STOW SDP-2/SDP-3 — GENERAL INFORMATION
Elevation
APPLICATION
Higher elevations will effect the performance of the pump. Due to
less atmospheric pressure at higher altitudes, pumps DO NOT
have the priming ability that they have at sea level. This is due to
the “thinner air” or lack of oxygen at higher altitudes.
The STOW Model SDP-2 and SDP-3 diaphragm pumps are
designed to be used for de-watering applications. The suction
and discharge ports on the SDP-2 use a 2-inch diameter opening,
which allows the pump to pump at rate of approximately 3,000
gallons/hour (gph) or 11,340 liters/hour (lph). The suction and
discharge ports on the SDP-3 use a 3-inch diameter opening,
which allows the pump to pump at rate of approximately 5,100
gallons/hour (gph) or 19,320 liters/hour (lph).
A general rule of thumb is that for every 1,000 feet of elevation
above sea level a pump will lose one foot of priming ability.
For example, in Flagstaff, Arizona where the elevation is
approximately 7,000 feet, the pump would have a suction lift of
only 18 feet rather than the 25 feet at sea level. Table 3 shows
suction lift at various elevations.
Diaphragm pumps use a positive displacement design rather
than centrifugal force to move water through the casing. This
means the pump will deliver a specific amount of flow per stroke,
revolution or cycle. These pumps are commonly referred to as
mud hogs, mud hens and mud suckers.Their names reflect their
popularity for use in applications where shallow depths and slurry
water render centrifugal pumps ineffective

These diaphragm pumps are powered by an 4.0 horsepower air
cooled, 4-stroke, single cylinder HONDA GX-120 gasoline engine
that incorporates a low "Oil Alert Feature" .The drive shaft of the
engine is coupled to an offset connecting rod that is coupled to a
flexible diaphragm. The connecting rod alternately raises
(expands) and lowers (contracts) the diaphragm at a rate
between 40 and 65 strokes per minute depending on engine
speed.

Oil Alert Feature
In the event of low oil or no oil, the HONDA GX-120 engine has
a built-in oil alarm engine shut-down feature. In the event the oil
level is low the engine will automatically shut-down.

Pump Support
The pump should always be placed on solid stationary ground
in a level position.
NEVER place the pump on soft soil. The suction hose or pipe
connection should always be checked for tightness and leaks. A
small suction leak in the hose or fittings could prevent the pump
from priming.

able, a rigid suction hose can be substituted in its place.
6. Make sure the suction strainer (Figure 2) is clean and
securely attached to the water end of the suction hose. The
strainer is designed to protect the pump by preventing large
objects from being pulled into the pump.
CAUTION :
Pump casing must be filled with water
before using pump. Otherwise pump will not
be able to begin pumping.
CAUTION :
The strainer should be positioned so it will
remain completely under water. Running the
pump with the strainer above water for long
periods can damage the pump.
WARNING :
DO NOT open fill cap if pump is hot! Water
inside may be under pressure.
CAUTION :
DO NOT pump flammable fluids, corrosive chemicals or fluids
containing toxic substances. These fluids can create potentially
dangerous health and environmental hazards. Contact local
authorities for assistance.

Hoses and Clamps
CAUTION :
This pump uses a water-cooled mechanical
seal to prevent water from seeping into the
engine.The passage of water through the pump
casing lubricates the seal and prevents it from
overheating. NEVER! operate the pump without
water in the casing as this will cause damage to the mechanical
seal.
1. Check that all hoses are securely attached to the pump.
Make certain suction hose (Figure 2) does not have any air
leakage.Tighten hose clamps and couplings as required.
2. Itisrecommendedthat 2 clampsbeusedwhensecuringthe
suction hose to the inlet side (suction) of the pump.
3. Remember suction hoses must be rigid enough not to
collapse when the pump is in operation.
4. Check that the discharge hose (Figure 2) is not restricted.
Place hose so that it lays as straight as it is possible on the
ground. Remove any twists or sharp bends from hose which
may block the flow of water.

STOW SDP-2/SDP-3 — MAINTENANCE (PUMP)
Pump Vacuum Test
Pump Cleaning
After pumping water containing large amounts of dirt and
debris, perform the following:
CAUTION:
DO NOT attempt to start the engine unless the
pump has previously been primed with water.
1. Remove the drain plug from the pump housing (Figure 2)
and drain any water left in the pump.
Severe pump damage will occur if pump has
not been primed.
3. Clean and remove dirt, debris from pump casing.Inspect
impeller and volute for wear. Replace any damaged or
worn parts.
To perform the pump vacuum test do the following:
Gear Reduction Oil (Transmission)
1. Remove the pump fill cap (Figure 2), and fill the pump
with water.
1.
Change transmission oil after the first 40 hours of
operation. Use SAE 80/90 EP gear oil. Transmission oil
capacity is 1-1/4 pints (590 ml.). Check oil level periodically
and change oil after every 400 hours of operation.
2. Start the engine as outlined in the initial start-up section,
and wait for the pump to begin pumping.
3. As shown in Figure 19 (next page), place a water hose
inside the discharge opening of the pump, and turn on
the water.This flow of water into the discharge opening
will prevent the pump from running dry.
Connecting Rod Bearing Lubrication
1. Grease connecting rod bearing thru the access
hole (Figure 7) every 25 hours of operation.
2.
Use only premium lithium based grease, conforming to
NLG1 Grade #2 consistency.
4. Place the Pump Vacuum Tester (P/N 7000030) over
the pump suction (inlet) opening (Figure 19) with the
vacuum gauge facing upwards. It may be necessary to
apply a small amount of water around the rubber seal of
the vacuum tester to make a good suction fit.
Connecting Rod Bearing Lubrication
1. Keep interior of pump and valves clean. Flush out
pump with clear water after operation.
2. Remove connecting rod guard occasionally and wipe
up excess grease from connecting rod bearing.
5. Check and make sure that there are no air leaks between
the vacuum tester and the inlet port on the pump. If air
leaks are present reseat vacuum tester.
6. Run the pump for a few minutes while monitoring the
vacuum gauge. If the gauge indicates a reading between
-25 and -20 in. Hg. (inches of mercury) then it can be
assumed that the pump is working correctly.
25 in. Hg (inches of mercury)
translates into 25 feet of lift at sea
level.
7. If the vacuum tester gauge indicates a reading
below -20 in. Hg, it can then be assumed that the pump
is not functioning correctly, and corrective action needs
to be taken.
6. To test the flapper valve, shut down the engine. The
vacuum tester should remain attached to the pump
suction inlet port by vacuum. This indicates the pump's
flapper valve is seating properly to hold water in the
suction hose when the engine is stopped.This prevents
backflow and allows for faster priming when the engine
is restarted.
