1.0 Introduction to Your Snapdragon
Coalescer
Thank you for purchasing the Zebra® Snapdragon™ Si-
erra™ Coalescer System to meet your oil maintenance
challenges.
This system is designed to be utilized on straight oil ap-
plications to filter out fine particulate and separate any
water-based liquid content. The oils will accumulate
inside the tank, and then be drawn through the ultra
filter to remove particulate. The filtered oil will then be
delivered against pressure to your holding vessel.
The water-based liquid content of your solution, if any,
will remain at the bottom the tank for manual discharge
to your waste container. Please make sure to discharge
the water portion on a timely basis so that oils are
always being fed to the ultra filter. If no oils are in the
holding tank of this unit, it will circulate the water portion
instead.

2.0 Precautionary Safety Measures
WARNING: Read, understand, and follow all instructions contained in this manual before starting. Keep
this manual in a safe, yet convenient, place for future reference.
WARNING: Failure to comply with all installation, operating, and maintenance guidelines will void all
warranties, may cause damage to the unit, or cause personal injury.
WARNING: It is the responsibility of the user to only allow individuals familiar with, and with full knowl-
edge of, this unit to install, operate, and maintain it. Zebra Skimmers Corp. will not be liable
for any damages due to lack of proper use of this equipment.
WARNING: Make sure you have the MSDS for your coolant on file, and measures related to its mixing,
measuring, maintenance, and disposal are read and understood. If you have any questions
regarding your specific coolant, contact your coolant supplier’s technical support service.
WARNING: Care must be taken at all times when handling coolant and waste oils. This includes utiliz-
ing safety glasses with side shield protection, gloves, longsleeved shirts and long-legged
pants. Sturdy shoes should also be worn, preferably with reinforced toes. Any liquids that
come into contact with the skin should be washed off with mild soap as soon as possible.
Liquid that comes into contact with the eyes should be washed out immediately with water
only.
WARNING: Tramp oils floating on coolant promote growth of anaerobic bacteria. These bacteria cre-
ate noxious gases, such as hydrogen sulfide (H2S) and hydrochloric acid (HCl). Hydrogen
sulfide causes unpleasant odors. Hydrochloric acid, however, can cause skin, eye, and
lung irritation. If these symptoms are present, consult a physician. Use the Zebra Muscle
Coalescer in a well- ventilated area to prevent these symptoms, should these gases be
present.
WARNING: Waste oil is hazardous and should be handled accordingly. Observe all proper national and
local disposal laws and regulations.
WARNING: Do not operate this equipment while under the influence of drugs or alcohol.

stand use with water, coolants,
and oils. Over time, however,
they may become stiff, depend-
ing upon your overall tank condi-
tions.
3.0 Component Review
Sumpster™ Skimmer
This free-standing skimmer in-
take attachment can be mount-
ed on the provided rod or on the
sump wall with a magnet, de-
pending upon your tank depth.
Position the Sumpster so the
top of the box is 1/4” ABOVE the
maximum fluid level in the tank.
It can handle a 3” fluid level drop
once installed.
You may contact your distributor for replacement hose
or choose your own. If choosing your own, please se-
lect a grade that has a wall thickness comparable to our
standard to prevent wall collapse and thus poor system
performance. Periodically inspect them for any block-
ages caused by debris to maintain system performance
and maximize pump life.
Push-to-Connect Fittings
The chip screen will prevent large floating chips, such
as aluminum and plastic, from clogging the intake hose
or damaging the pump diaphragms and other internal
pump components. Periodically clean the debris to
maintain the 1 gpm flow rate of the system and to maxi-
mize the pump life.

Pressure Limiter
Zebra incorporates a pressure limiter to
prevent over-pressurization of the pump
diaphragms, which leads to immediate
pump failure.
Cam Lock Quick-Connectors
If more than 85psi is needed to draw fluid through the
system, thorough inspection of the intake attachment,
connectors, hoses, and fittings is needed. It is likely that
there is a vacuum leak caused by an improper seal of
one of the above components or there is a debris block-
age in the system.
We supply these con-
nectors standard with
the Sierra. The female
is permanently fixed to
the oil intake hose and
the male to the end of
the intake attachment.
Before making the con-
nection, verify that the interiors of these connectors are
free of chips, debris, and oil residue to maintain a tight
seal.

Pressure Regulator and Lubricator Package
Baffled Anti-Turbulence System (BATS)
Use the adjustment knob
of the pressure regulator to
adjust the air pressure going
through the pump. It must be
pulled up before adjusting.
The BATS is made of PVC and acts to remove air
bubbles from the incoming fluid. In so, turbulence is
lessened in the coalescing tank, aiding in the separation
of oil and water-based fluids.
Pressurized Filtered Oil Return System
Check the oil atomizer, lo-
cated near the air line and
behind the regulator, to verify
The oil return piping system will remove oil from the
coalescing tank, circulating it through the pump to the
ultrafilter. After ultrafiltration, it is then pumped under
pressure to your holding vessel.

that it is running at approxi-
mately one drop every 2-3
minutes. This atomizer feeds
lubrication to the air line and
should be refilled with ISO
32 SAE10 Airline Lubricating
(mineral) Oil when necessary. Use of the wrong oil may
cause o-ring failure. If there is oil leaking from the muf-
fler, adjust the oil atomizer valve.

Air-Diaphragm Pump
Periodically inspect the cartridge to deter-
mine whether it needs replacement. Another
good indication for replacement is if the
system requires more than 40psi to maintain the proper
flow rate. Also verify that the o-ring is free of debris be-
fore reinstallation.
The 1/2” air diaphragm pump
is the heart of the system and
should be well maintained. Ze-
bra has chosen this particular
brand pump for its durability and
ease of maintenance.
Overfill Prevention Line
In normal operation, it will emit a
thumping sound. The faster the
sound, the faster fluid is moving
through the system.
This line, which is the 1/4” clear hose, recirculates up to
10% of the fluid back through the right side of the pump
to prevent the coalescing tank from overflowing.
Ball Valve for Waste Fluid Discharge
The pump can handle lifting fluids 15 feet on the intake
side. However, it develops great pressures on the out-
put side, and care must be taken to never try to restrict
the fluid flow in any way.
The waste fluid, whether it’s water or coolant, will settle
onthebottomofthecoalescingtank. Itwillbenecessary
to manually discharge this fluid to a waste container be-
fore its level reaches that of the oil return piping. NOTE:
Waste waters will recirculate through the ultrafilter and
into your holding vessel if not regularly discharged.
For more information on the pump, please refer to the
Third Party Information in the Appendix of this manual.
Coalescing Tank
The coalescing tank is made of polyethylene to with-
stand oils and coolant. It is not made to withstand
punctures or shock, so care must be taken to prevent
damage.
It can hold approximately 19 gallons of liquid. You will
need to prefill the tank with oil only in the event that your
application requires no oil to be “removed” from the tank
in service.

Chapter 4 System Operation & Maintenance
4.1 Oil Accumulation for
4.0 Installation & Usage Guidelines
Ultrafiltration & Waste Discharge
1. Inspect the unit to make sure it is in good operat-
ing condition.
Once the fluid is drawn into the coalescing tank, it will
begin to separate into two main layers. The oil com-
ponent will float towards the top of the tank and wa-
ter-based fluids will accumulate near the bottom of the
coalescing tank. The degree of this separation will be
strictly determined by these factors:
2. Fill the coalescing tank with 3 gallons of water to
fill the waste discharge pipe column. NOTE: If
the coalescer tank is not pre-filled, oils will enter
this column and your first waste discharge may
contain oil until this column fills with water-based
fluid.
• The strength of the water-based fluids anti-emulsi-
fication components (as in metalworking fluid, aka
coolants)
3. Secure the filtered oil return hose to your pre-
ferred holding vessel using the magnet, pro-
vided.
• The age and quality of the water-based fluid to be
manually discharged
4. Install your preferred fluid intake attachment, ac-
cording to the guidelines in Section 3.0, quick-
connecting it to the fluid intake hose.
• The age and quality of the oil to be ultrafiltered
• Chemical instabilities caused by other additives en-
tering fluid pool
5. Connect your air hose to the air connection fit-
ting.
• The flow rate of the coalescing system
6. Lift the air regulator knob and adjust until the
pressure is approximately 10-20 psi. NOTE:
You will need to adjust this pressure higher as
the filters fill with debris, if there is a blockage
in a line or fitting, or there is a loss of vacuum
pressure due to an improper seal. In each of the
previous cases, it is recommended to correct
the problem and not use excessive pressure
to operate the system. This will ensure a proper
flow rate for maximum oil/water separation.
Maintain a regulated flow rate so it provides for a proper
hold time for all fluids to separate, usually 1-2 gallons
per minute.
If there is not a complete separation of the oil and water
portions, then a slower flow rate may be necessary, as
your fluids have lost the ability to gravity separate within
10-20 minutes. You may notice a third layer which does
not completely separate at all. These are called inverse
layers, and are generally caused by high-pressure sys-
tems which further emulsify oils into one another. Con-
sider this layer as waste and discharge it regularly.
The Snapdragon Sierra is not guaranteed to separate
a straight oil from another straight oil and/or tramp oils.
Before reusing any straight oil, verify its integrity.
Manually discharge the wastewater portion to a waste
container, via the ball valve, so as not to recirculate it
through the ultrafilter and into your preferred holding
vessel. NOTE: We recommend maintaining a waste
water level of about a third of the tank heighth to main-
tain the separated fluid layers. ALWAYS discharge the
waste fluid while the pump is running to prevent vacuum
loss in the waste discharge pipe.

4.2 Finishing Up
4.4 Storing the System
1. Once the oils have been removed from the tank
being skimmed, disconnect the intake hose from
the intake attachment via the quick connection.
It is recommended to empty the coalescing tank before
storing the system for more than 1 or 2 days. Holding liq-
uid in the tank can contribute to bacterial contamination
of the coalescer, and thus your equipment. We recom-
mend utilizing an Oxygenator™ when storing fluids in
the coalescing tank to minimize bacterial growth.
2. Before shutting off the pump, lift the intake hose
out of the tank for about 10 seconds. This will
ensure that no liquid is still in the intake line.
3. Shut the pump off by adjusting the regulator.
NOTE: See Section 4.3 for details on empty-
ing the tank, if necessary, before proceeding
further.
4.5 Cleaning the System
1. Empty and clear the coalescing tank and both
hoses of all fluids (refer to Section 4.3)
4. Disconnect your air line from the air intake fit-
ting.
2. Discard the cellulose ultrafilter.
3. Mix a 10% solution of a mild degreasing agent,
such as Red Thunder™, provided, to clean the
coalescing tank and stainless steel prefilter. A
pressure washer works well, or just clean by
hand with the brush, provided.
5. Remove the return line from the tank being
skimmed by lifting it near its connection to the
coalescing tank to free it of liquid.
4.3 Emptying the Coalescing Tank
4. Rinse thoroughly with straight water.
1. Open waste water ball valve to manually drain
any wastewater to your waste container, then
close (refer to flow schematic in Section 3.2).
5. Dispose of wash and rinse baths in accordance
to federal, state, and local environmental laws
and regulations.
2. Tilt, in an upward position, the prefilter and ultra-
filter housings.
6. Replace filters, making sure o-rings are free of
debris and seated correctly.
3. Close ball valve for the oil ultrafiltration line (refer
to flow schematic in Section 3.2).
7. Double-check all hoses, fittings, and attach-
ments for cracks and obstructions.
4. Open ball valve for oils to be emptied from tank
(refer to flow schematic in Section 3.2).
5. Place the oil return line into your preferred oil
holding vessel. Make sure that it can hold the re-
maining amount of oil left in the coalescing tank.
CAUTION: Fluid is returned under pressure.
6. Adjust the air regulator of the pump to 10psi.

regulator to desired downstream pressure. This permits pressure to build up slowly
in the downstream line.
5. To decrease regulated pressure settings, always reset from a pressure lower than
the final setting required. Example, lowering the secondary pressure from 550 to 410
kPa (80 to 60 psig) is best accomplished by dropping the secondary pressure to 350
kPa (50 psig), then adjusting upward to 410 kPa (60 psig).

It is necessary to install a gauge or pipe plug into each port during installation.
4. To protect regulator units against rust, pipe scale, and other foreign matter, install
a filter on the upstream (high pressure) side as close to the regulator as possible.
WARNING To avoid polycarbonate bowl rupture that can cause personal injury or property damage,
do not exceed bowl pressure of temperature ratings. Polycarbonate bowls have a 150 psig (1030 kPa)
pressure rating and a maximum temperature rating of 52°C (125°F).
Caution: For proper assembly of P3A-RN and 8AR fittings, they must be installed
hand-tight and then tightened by wrench 1/2 turn. To prevent leakage past
threads, apply thread sealant to fitting. Prestolok fittings are recommended. Use
of hard pipe is not recommended.

1. Before turning on air supply, turn adjusting handle counterclockwise until
compression is released from control spring. Then turn on air supply and adjust
regulator to desired secondary pressure by turning adjusting handle clockwise. This
permits pressure to build up slowly, preventing any unexpected operation of the valve,
cylinders, tools, etc., attached to the line. Adjustment to desired secondary pressure
can be made only with primary pressure applied to the regulator,
2. To decrease regulator pressure setting, always reset from a pressure lower than
the final setting desired. For example, lowering the secondary pressure from 550 to
410 kPa (80 to 60 psig) is best accomplished by dropping the secondary pressure to
350 kPa (50 psig), then adjusting upward to 410 kPa (60 psig).

SAFETY: Transparent Bowls
Caution: Polycarbonate bowls, being transparent and tough, are ideal for use
with Filters and Lubricators. They are suitable for use in normal industrial
environments, but should not be located in areas where they could be subject
to direct sunlight, an impact blow, nor temperatures outside of the rated range.
As with most plastics, some chemicals can cause damage. Polycarbonate
bowls should not be exposed to chlorinated hydrocarbons, ketones, esters and
certain alcohols. They should not be used in air systems where compressors are
lubricated with fire resistant fluids such as phosphate ester and di-ester types.
Servicing Filter Element:
Note: See Figure 1 to aid with this procedure.
1 . Unscrew threaded bowl and element holder. Then remove filter element,
deflector, and gaskets.
2. Clean all internal parts, bowl, and body before re-assembling unit. See
Polycarbonate bowl cleaning section.
3. Install deflector, filter element, and gaskets.
4. Attach element holder. Torque 0.9 to 1.4 Nm (8 to 12 in-lbs).
5. To assist with retaining bowl’s o-ring while installing bowl, lubricate the o-ring (with
a mineral based oil or grease). Then place it on the bowl.
6. Screw bowl into body until it is stopped by body; then back off bowl 1/8 turn.
7. Apply pressure to the system and check for leaks. If leaks occur, shut off the
air supply, de-pressurize the system and make necessary adjustments to eliminate
leakage. If you have questions concerning how to service this unit, contact your local
authorized dealer or your customer service representative.
Metal bowls are recommended where ambient and/or media conditions are not
compatible with Polycarbonate bowls. Metal bowls resist the action of most such
solvents, but should not be used where strong acids or bases are present or in
at laden atmospheres. Consult the factory for specific recommendations where
these conditions exist.
TO CLEAN POLYCARBONATE BOWLS USE MILD SOAP AND WATER ONLY!
DO NOT use cleansing agents such as acetone, benzene, carbon tetrachloride,
gasoline, toluene, etc., which are damaging to this plastic.

HAZARDOUS MATERIAL: Protective eye wear and clothing should
be used whenever pumping hazardous or toxic fluids.
• If a diaphragm ruptures, the pumped product can enter the air side of the pump and
exit through the air exhaust. When the fluid is hazardous pipe exhaust away from the
work area and personnel.
• When the fluid source is at a higher level than the pump (flooded suction), the
exhaust should be piped to a higher level than the fluid source to prevent spills
caused by siphoning if a diaphragm rupture should occur.

Performance Curve
1. A lube-free, clean, dry, compressed air source (or any nonflammable, compressed
gas) is recommended. Use a filter that is capable of filtering out
particles larger than 50 microns.
2. All pumps should be mounted in an upright position with the exception of the 1/4”
models which may be rotated 360° to suit the application.
3. When particles exceed the maximum particle specification of the pump or are
sharp enough to cut elastomers install a particle fluid filter on the fluid
suction line.
4. Fluid suctions lines and air exhaust lines should never be smaller than specified
pipe size of pump.
5. Apply PTFE tape to threads upon assembly to prevent leakage.
6. Never use pipe dope on air line connections.
7. Never use collapsible tube on fluid inlet.
8. Do not exceed 10 ft-pounds of torque on plastic pipe threads.
9. If changing to a different application reconfirm compatibility of fluid.
GENERAL MAINTENANCE
1. Check periodically for product or air leakage. Tighten any joint where leakage is
occurring.
2. When pumping hazardous or toxic materials, diaphragms should be replaced at
regularly scheduled intervals based upon pump usage.
3. In freezing temperatures, the pump must be completely drained when idle.
4. When pumping highly abrasive fluids reduce discharge flow rate or reduce air
pressure to prolong diaphragm life.

1. Check all suction line connections for leakage.
2. Inspect check valves for wear or debris.
3. Suction lift specifications may be exceeded.
4. If fluid is viscous use larger suction lines.
8. Position outer diaphragm chambers onto intermediate making sure that witness
lines are matching.
NOTE: If air valve has been removed, proper orientation of air system with fluid
chambers must be observed. The top of the intermediate has a single vertical air
passage slot on the air valve mounting face while the outer chamber check ball cavity
should be pointing downward.
LEAKAGE
9. When positioning band clamps use soapy water or a compatible lubricating spray
on the inside of band clamps to aid assembly. Tap with a mallet on the outside of
clamp to help position the clamp while tightening the fasteners. The band clamp
fasteners are stainless steel. To prevent galling always apply an anti-seize compound
to the thread. Tighten all external fasteners to final torque requirement after pump is
completely assembled.
10. Position the reassembled manifolds making sure of the proper orientation in
relation to the air valve for your application. Also make sure that the valve seat o-rings
do not shift from their grooves during reassembly. Flat washers should be placed
under the head of each cap screw and nut. Tighten all external fasteners to final
torque requirement after pump is completely assembled.
1. Retorque all fasteners to specified torque requirements.
2. Replace o-rings.
3. Inspect diaphragms for rupture
LOW FLOW RATE
1. Confirm air pressure and air capacity at the air valve as required.
2. Check for leaks in suction line or obstructions in lines.
3. If fluid is viscous use larger suction lines.
4. Viscosity of fluid may have increased if temperature is lower.
AIR IN DISCHARGE LINES
1. Check for leaks in suction lines.
2. Inspect diaphragms for rupture.
External Fastener Torque Requirements
ERRATIC CYCLING
1. Inspect check valve seats for debris.
2. Inspect fluid lines for debris.
3. Automatic valves must be properly functioning.
4. Viscosity of product may be changing.
PREMATURE DESTRUCTION OF WETTED COMPONENTS
1. If fluid is abrasive slow down pump or increase size of pump
2. Filter fluid for sharp objects.
NOTE: When reassembling loosely tighten all external fasteners adjusting and
aligning and gradually, in an alternating fashion, tighten to torque requirements listed
below.
AIR VALVE CAP SCREWS 40 in-lbs (4,52 NM)
BAND CLAMPS 13.3 ft-lbs (18,08 NM)
MANIFOLD BOLTS, 20 in-lbs (2,26 NM)
OUTER CHAMBER CAP SCREWS, 28 in-oz (0,02 NM) (Plastic Pumps)
OUTER CHAMBER CAP SCREWS, 30 in-lbs (3,39 NM) (Metal Pumps)
3. Make sure fluid is compatible with wetted materials.
Air Valve Maintenance
11. To evaluate air valve components, remove the four cap screws (11), washers,
(25, 10) and nuts from the air valve body (7). The valve plate (5) and shuttle (6) may
be inspected by removing them from their location in the slot in the back of the air
valve. Inspect for scratches or surface irregularities. Replace if necessary. To remove
the plug (1) at the bottom of the air valve, point the bottom of the air valve safely away
from people, direct compressed air through one of the lower holes in the back of the
air valve body and the plug will shoot out. Next push the air valve spool (2) out of the
air valve body. Gently reach in and pull lip seals (43) out of inside bore of the air valve
body. Check for cracks, splitting or scratches. Clean components if replacement is
not necessary. Inspect plug oring (44) for any damage and replace if necessary and
reinsert in o-ring groove.
NOTE: Make sure that the open side of the two lip seals face each other when
reassembling air valve. Lube all components with suggested maintenance grease as
an aid in reassembly.
12. Reinsert air valve spool inside of air valve body. Place shuttle on middle rib of
air valve spool through the square slot in back of air valve. If using original valve
plate lubricate side of plate that was facing the shuttle (or if new valve plate is used
lubricate the lapped and polished side of plate) and place the lubricated side next to
the shuttle in the slot. Press valve plug into air valve body, chamfered end first.
13. Check that gaskets (3, 4) are not cracked. If damaged replace.
1⁄2˝ MODELS
MAINTENANCE MANUAL
Check Valve And O-ring Maintenance
1. Flush and neutralize the pump to be certain all corrosives or hazardous materials
are removed prior to any maintenance. This procedure should always be followed
when returning pumps for factory service also.
2. Remove the nuts (19) and washers (10) from the four long pumping cap screws
(35). Suction check valve seats and check balls (26, 27) are located inside of the
bottom of the outer chamber (28). Gently remove and inspect for excessive wear,
pitting or other signs of degradation. Inspect valve seat o-rings (38). Replace if
necessary. Discharge check valves are located inside of the bottom of the discharge
elbows (28). Repeat procedure for inspection of discharge check valves.
3. To inspect the manifold o-rings remove the eight sets of nuts, washers and bolts
(10, 19, 20) from each manifold assembly and replace if necessary. Then reassemble,
lightly tighten fasteners. Tighten all external fasteners to final torque requirement after
pump is completely assembled. The check ball should fit into the curved portion of the
valve seat and be facing upward when reinserted into the valve seat location.
NOTE: When using pumps built with PTFE o-rings always replace with new PTFE
o-rings, since the original o-rings will not reseal the pump.
14. After gaskets are pressed back into position align air valve onto intermediate and
reinsert the four capscrews with lock washer and flat washers. Apply 40 in-lbs (4,52
NM) of torque to fasteners.
Diaphragm And Pilot Sleeve Assembly Maintenance
4. To inspect diaphragms remove the band clamps (16) from the
outer pumping chambers (28). If replacement is necessary due to
abrasion or rupture unscrew the outer diaphragm plates (29). Models
that are built with PTFE elastomers will have a PTFE overlay (30) that
faces the outer pumping chamber and a back-up diaphragm (31) on
the air side of pump. Pumps without PTFE will contain only the back-
up diaphragms.
5. If there has been a diaphragm rupture and corrosive or viscous
fluid has entered the air side of pump the complete air system should
be inspected. After removing diaphragms and inner diaphragm plate
(33), the pilot sleeve assembly (14, 40, 42, 45-47) and diaphragm
rod assembly (13, 15) may be removed by removing the retaining
plates (41) (you may only need to remove one retaining plate) and
pushing the entire unit out through the bore in the intermediate (34).
Diaphragm rod assembly must be unscrewed to remove pilot sleeve.
NOTE: To aid in reassembly use a non-synthetic, petroleum based
lubricating grease without EP additives. Carleton-Stuart MagnaLube
G is recommended.
6. Clean or replace any components that have excessive wear,
dirt build-up, or chemical attack. Lube all components prior to
reassembling. Reassemble pilot sleeve spacers, o-rings and lip seals
(40) within bore of intermediate. Make sure that the open side of the
lip seals is facing outward toward the diaphragms. Also make sure
that the end pilot spacers (14) are at the end on either side of the pilot
sleeve assembly and all inner spacers (47) are separated by o-rings.
Next carefully insert the diaphragm rod assembly with pilot sleeve
inside the assembly in the bore. Reattach retaining plates. Do not
overtighten self-tapping screws (24).
7. Take one diaphragm and invert (reverse the natural bow of the
material) and with the curved side of the inner diaphragm plate facing
the diaphragm assemble onto outer diaphragm plate stud and then
screw assembly into diaphragm rod. Push diaphragm rod to opposite
side of intermediate and add the opposite diaphragm assembly.
Tighten the outer diaphragm plates to 70 in-lbs (7,91 NM) of torque.
NOTE: Inverting the first diaphragm aids reassembly.
