❑ Operation
32 Silencer Series Booster Pump, p/n: 029-0020-83-0
WARNING !
DO NOT ADVANCE THE THROTTLE UNLESS THE “OK TO PUMP” INDICATOR
IS ON.
7. Verify the pump panel shift indicator light is ON.
8. Activate the priming pump by pulling the control handle located on the pump
panel or pressing the push-button.
Running the engine at speeds higher than 1,200 RPM during priming is not
recommended. It does not improve the priming operation but can cause
damage to the pump.
CAUTION !
IF DISCHARGE GAUGE READING DOES NOT INCREASE, THE INTAKE
GAUGE READING DOES NOT FALL BELOW ZERO, OR THE PRIMING PUMP
DOES NOT DISCHARGE WATER TO THE GROUND WITHIN 30 TO 45 SEC-
ONDS, DO NOT CONTINUE TO RUN THE PRIMING PUMP.
STOP THE PUMP AND CHECK FOR AIR LEAKS OR POSSIBLE PROBLEMS.
SEE SECTION 5 “TROUBLESHOOTING,” ON PAGE 55.
9. Monitor the intake and discharge master gauges. The pump is primed when
the intake reading falls below zero (0), and the discharge pressure starts to
increase. Water can also discharge to the ground.
10. Gradually open the discharge valve until water emerges in a steady stream.
Then open the engine throttle gradually until the desired pressure or flow is
achieved.
As the throttle is opened, the pressure gauge reading increases with engine
speed. If the engine speed increases without an increase in pressure, the
pump is cavitating. Reduce the flow from the pump to maintain pressure.
Note: Also see heading “Cavitation” on page 36.
11. If a pump shutdown is desired while pumping from draft, reduce the engine
speed to idle, and close the discharge valves.
To resume pumping, open the throttle and discharge valves. To prevent the
pump from overheating due to continued churning without water flow, open
the tank fill valve, the pump cooler valve, or discharge to ground.
