PULLEY INFORMATION  
Pulley selection and pump speed are based on a 1725  
RPM motor and "B" section belts. When selecting  
desired GPM, allow for a ±5% tolerance on pumps  
output due to variations in pulleys, belts and motors  
among manufacturers.  
1. Select GPM required, then select appropriate  
motor and pump pulley from the same line.  
2. The desired pressure is achieved by selecting the  
correct nozzle size that corresponds with the pump  
GPM.  
HORSEPOWER INFORMATION  
Horsepower ratings shown are the power require-  
ments for the pump. Gas engine power outputs  
must be approximately twice the pump power  
requirements shown above.  
We recommend that a 1.1 service factor be specified  
when selecting an electric motor as the power source.  
To compute specific pump horsepower requirements,  
use the following formula:  
(GPM X PSI)/1450 = HP

REPAIR INSTRUCTION - LP121HT PUMP  
To Check Valves  
Loosen valve plugs (48). Either with needle nose pliers or with a M12 screw, which can be  
threaded into the hole of the spring retainer (46D), take out discharge and inlet valve  
assemblies. Press onto the valve plate (46B) and twist to take apart the valve assembly.  
Check and replace worn parts. Tighten the plug to 107 ft.-lbs.  
To Check Seals and Plungers  
Loosen the eight nuts (49A) and take off the valve casing (43). Remove the seals (40) on the  
valve casing. Take seal sleeve (35) out of the guides in the crankcase (1) and remove the  
leakage seals (36).  
Check plunger pipes (29B) for damage and remove any dirt. When replacing plunger pipes,  
use new copper rings (29D). Apply loctite on threads of plunger bolts (29C) and tighten to 33  
ft.-lbs.  
Check seals and replace as necessary.  
Place new v-sleeves (40) along with support rings (41) in the valve casing (43). Place seals  
(36) and pressure rings (39) in seal sleeve (35). Install the complete unit in the valve casing.  
Finally, fit in the complete pump head assembly carefully over the plunger pipes and evenly  
tighten nuts to 59 ft.-lbs.  
To Dismantle Gear End  
After removing the valve casing (1) and plunger pipes (29B), drain the oil. Take off crankcase  
cover (4) and bearing cover (14). Loosen connecting rod screws (24) and push the connecting  
rod/plunger base assembly forward (as far as possible) into the crosshead guides. Caution:  
Connecting rods are marked for identification. Do not twist connecting rod halves.  
Connecting rods are to be reinstalled in the same position on the crankshaft journals.  
Turning the crankshaft (22) slightly, hit it out carefully to the side with a rubber hammer.  
Caution: Do not bend the connecting rod shanks. Check crankshaft and connecting  
rod surfaces, shaft seals (15) and taper roller bearings (20).  
To Reassemble  
Using a soft tool, press in the outer bearing ring until the outer edge is aligned with the outer  
edge of the bearing hole. Take off bearing cover (14) together with shaft seal (15) and o-ring  
(16). Fit crankshaft (22) through bearing hole on the opposite side. Press in outer bearing  
and tension it inwards with the bearing cover (keeping the shaft in a vertical position and  
turning slowly so that the taper rollers of the bearings touch the edge of the outer bearing ring).  
Adjust axial bearing clearance to at least 0.1mm and a maximum of 0.15mm by placing fitting  
discs (20A and 20B) under the bearing cover. Caution: After assembly, the crankshaft  
(22) should turn easily with very little clearance. Tighten connecting rod screws (24) to  
310 in.-lbs.

Supplementary Plant Lay-Out Instructions - LP121HT PUMP  
Pressure in Inlet Side  
The stipulated NPSHR is the minimum required pressure above the vapor pressure of the  
medium and is never to fall short of this figure. Temperature and vapor pressure of the  
medium, the geodetical height of the location, the flow rate and the loss of friction in the suction  
line, must all be taken into consideration. It may be necessary to install a booster pump  
(centrifugal) in the suction line.  
Pulsation  
Due to its construction, the plunger pump creates pulsation in the inlet and discharge lines. In  
particular, inlet pulsation must be dampened in order to prevent resonance in the suction line  
which in turn causes cavitation. Therefore, the pump is never to be connected by a rigid pipe.  
Rather, use a flexible hose, which is not reinforced by steel, that is 1.5 to 2 times wider than the  
inlet port. If a booster pump is used, the hose is to be attached between the booster pump  
and the high pressure pump.  
If several pumps are used, each pump must have its own inlet line. If this cannot be done, an  
inlet air chamber or inlet flow stabilizer must be installed in front of each pump. The bladder in  
the stabilizer is to be pre-tensioned on location.  
Depending on the layout of the plant, a pressure accumulator may be necessary on the  
discharge side. The pressure accumulator must be installed right behind the discharge outlet  
of the high pressure pump. Only use one pressure accumulator (in the discharge line) at a  
time in order to avoid irritation which could be caused by different pretension levels in the  
accumulators.  
Gas-tension in both the inlet flow stabilizer and the pressure accumulator are to be checked  
regularly.
