Installation Highlights:
The proper installation of your SPM well service pump is a must in obtaining long life and trouble free service.
Particular attention must be given to the following items:
A. Power Source:
The prime mover (usually a 2100 RPM diesel engine) should not be rated at more than
725 BHP intermittent service in order to avoid overpowering the pump.
B. Drivetrain:
The drivetrain which connects the pump to the engine should include a transmission (5 speed or more)
and a mechanical driveline with universal joints and a slip joint in order to fully utilize the pump's wide
range of pressure and flow capabilities.
A powershift type transmission with integral torque converter and automatic lock-up clutch will provide the
most trouble-free means of shifting under pressure. When using an ordinary mechanical transmission
with manual clutch, extreme caution must be exercised when clutching and shifting in order to avoid
introducing severe shock loads to the pump's input shaft. When using any transmission with a “high
gear” or “overdrive” ratio greater than 1.0:1, the “overdrive” gear range must be blocked out in order to
avoid overspeeding the pump. When using a transmission with a torque converter and/or a low gear
ratio of 5.0:1 or lower, extreme caution should be exercised to avoid over-pressuring the pump when
operating in low gear or converter mode.
The mechanical driveline should have a “Diesel Engine Use” torque rating of approximate 1250 to 1700
ft. lbs. (6500 to 8900 ft. lbs. Short Duration) and should have no less than 1” slip capacity. The
manufacturer's recommendations for maximum installed angle, maximum RPM, etc. must not be
exceeded.
C. Power End Mounting:
The pump must be securely bolted to the skid or vehicle at all four power end mounting hold locations
(Refer to pump installation drawing).
D. Power End Lubrication:
SPM
®
well service plunger pumps are shipped dry, do not include an integral oil pump, and are designed
for a pressure lubricated dry sump system. An auxiliary oil reservoir and engine driven oil pump must be
provided for proper lubrication. More information pertaining to the power end lube system and power end
lube oils is included in this manual.
