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:
Power Source :
The prime mover (usually a 1900 to 2100 RPM diesel engine) should be rated at no more than 2700 BHP
intermittent service in order to avoid overpowering the pump.
Drivetrain:
The drivetrain which connects the pump to the engine should include a transmission (7 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 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. Extreme caution should be exercised in order 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 20,000 ft. lbs. (96,000 ft. lbs. Short
Duration) and should have no less than
1” slip capacity . Weir Oil and Gas recommends a maximum driveline
angle of 3 degrees.
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).
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 on page 30.
Plunger Lubrication:
Complete information on the plunger lubrication can be found in the SPM
®
QWS2500 fluid end operation
instruction and service manual . SPM
®
document number 2P136539.
Supercharging System:
SPM
®
well service plunger pumps require the use of a centrifugal slurry pump supercharging system to avoid
cavitation at the higher pump speeds. More information pertaining to the supercharging requirements is
included in this manual.
