SUNPUMPS SPB-SERIES
PISTON PUMP SERVICE MANUAL
Caution: Piston pumps are positive displacement pumps. Therefore, a properly
designed pressure RELIEF OR SAFETY VALVE MUST BE INSTALLED in the
discharge piping. Failure to install such a relief mechanism could result in personal
injury or damage to the pump or system. SunPumps does not assume any liability or
responsibility for the operation of a customer’s high-pressure system.
INSTALLATION AND START-UP INFORMATION
Optimum performance of the pump is dependent upon the entire fluid system and will be
obtained only with the proper selection, installation of plumbing and operation of the
pump.
LUBRICATION: Fill crankcase with special hydraulic oil per pump specifications.
DO NOT RUN PUMP WITHOUT OIL IN CRANKCASE. Change initial fill after 50
hours running period. Thereafter, change oil every three months or at 500 hour
intervals.
PUMP ROTATION: Pump was designed for forward rotation to allow optimum
lubrication of the crosshead area. Reverse rotation is acceptable if the crankcase oil level
is increased slightly above center dot to assure adequate lubrication.
To minimize piping stress, use appropriate flexible hose to inlet and discharge ports.
Use the correct belt; make sure pulleys are aligned. Excessive belt tension may be
harmful to the bearings. Hand rotate pump before starting to be certain shaft and
bearings are free moving.
LOCATION: If the pump is used in extremely dirty or humid conditions, it is
recommended pump be enclosed. Do not store or operate in excessively high
temperature areas or without proper ventilation.
INLET CONDITIONS: Refer to complete Inlet Condition Check-List in this
manual before starting system. DO NOT STARVE THE PUMP OR RUN DRY.
DISCHARGE PLUMBING: OPEN ALL VALVES BEFORE STARTING
SYSTEM to avoid deadhead overpressure condition and severe damage to the pump or
system.
Install a Pulsation Dampening device mounted directly to the discharge line. Optimum
precharge should be calibrated at 30-50% of the operating system.
A reliable Pressure Gauge should be installed near the discharge outlet of the high-
pressure manifold.
The pump is rated for a maximum pressure; this is the pressure, which would be read at
the discharge manifold of the pump.
