Davey 4 Floodfighter Pumps - Manual (Page 3)

PUMP LOCATION:
For most efficient operation, site the pump as close to the water as practical.
It is essential for the correct function of the engine that it be located on a
horizontal surface. If allowed to run at an inclination, the oil lubrication system of
the engine may not operate correctly. Subsequent engine failure would not be
covered by the manufacturer’s guarantee.
The pump should be positioned in a well drained location to avoid possible
property damage by leaking hose fittings or pump seals, spilled engine fuel etc.
If you intend to operate your pump on a hard surface, Davey suggest a suitable
resilient mounting to be fitted to your pump and engine.
SUCTION PIPE:
The Floodfighter
™ , depending upon the model, uses a 3” or 4” suction pipe.
Always locate the pump so that the rise of suction pipe from the water is even
with no humps or hollows where air may be trapped. All pipe connections must
be air tight for best priming and pump operation – check that washers in nuts and
tails are in good order.
DISCHARgE PIPE:
Care should be taken with the selection of pipe pressure rating as the 3”
Floodfighter
™ is capable of delivering pressures of 250kPa.
PUMP PRIMINg:
To prime the pump initially, it is necessary to fill the pump body with water before
starting the engine.
Choke and start engine, open discharge then allow the pump to run until it is
drawing water.
The pump will establish prime better at higher engine speeds. Allow up to 3
minutes for long or deep suctions.
If the pump fails to prime, then it may be due to the pump flap valve not seating
properly, an air leak in the suction pipe or fittings, a blocked suction pipe, or the
bottom end of the pipe embedded in mud.
NOTE: When transporting your Davey Floodfighter ™ Pump,
water from the casing may leak back past the priming flap.
before attempting to self prime the pump you may need to
check that the pump casing is full of water.
