Engine Driven Pump
Model GP960
Please read these instructions in full before installing and commission-
ing the pump unit.
Pump Protection
Warranty of these pumps is void unless they are housed correctly and
protected from weather, floods, chemicals, dust, vermin, insects etc.
Housing used should be weather-proof and well vented so that engine
heat and exhaust fumes can escape. To obtain best possible perform-
ance, pumps should be installed as close to water as possible.
Suction and Discharge Pipes
Suction pipe should be laid so that it rises evenly from water source to
pump. This makes priming easy and avoids airlocks.
Hoses should be the same size as the pump inlet and/or larger than the
discharge port.
All pipe joints must be sealed to ensure they are airtight.
Priming
To prime pump, remove priming plug and fill pump and suction pipe
with water. Pump is equipped with suction flap valve and should be
capable of drawing air out of normal size suction pipes or hoses. Re-
place plug and start the pump. If the pump pumps a little and stops,
turn the pump off, check suction pipe for possible leaks and repeat
priming procedure until the pump operates satisfactorily.
Self priming pumps, when filled with water, will gradually draw air out
of the suction line (depending on model) to a maximum vertical lift of
6 metres (20 ft). If priming a long or large diameter pipe, additional
water may have to be added to the pump at 3 minute intervals.
