    This pump is light weight (22Kg dry weight) and comes with a carry handle for
    easy portability.

    Pump Location

    • For the 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 pumps 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.

    A reinforced or non-collapsible hose should be used for the pump suction. The
    minimum suction pipe size should be 50mm (2”) I.D. A strainer should always be
    fitted to the bottom of the suction pipe. The strainer should be kept out of sand,
    mud, etc., to avoid particles being drawn into the pump and causing damage by

    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 to ensure the best priming and operation of
    the pump. Check that the washers in nuts and tails are in good order.
    Discharge Piping
    Care should be taken on correct selection of discharge pipe pressure rating as the 2”
    Poly Pump is capable of delivering pressures up to 280kPa (41psi). The pump outlet
    is 2” BSP female and 2”, or larger, polythene piping or equivalent should be used.


    Priming the Pump

    • Do not attempt to run pump if the pump casing (pump body) has not been filled with water (primed). Severe damage will result to
      mechanical seal.
    • To prime the pump initially, it is necessary to fill the pump body with
      water before starting the engine. Remove the priming cap (on top of
      the pump casing near the discharge port). Fill the pump body with
      water and refit the priming cap tightly.

    Choke and start the engine, open the discharge valve and 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 lifts.

    High performance can be obtained from these pump if the engine speed is
    increased, however, we do not recommend the pump be operated over 3,600rpm
    for extended periods as this may overload the engine. Operating the engine
    at full throttle for extended periods will shorten the engine’s life and may result
    in premature failure. For operations such as irrigation or dam and tank filling,
    the throttle should be closed to around ¾ maximum. This should correspond to
    around 3,000rpm maximum.

    When pumping other than clean water, the specific gravity or relative weight of
    the fluid may be different to water. If the fluid being pumped is heavier than water,
    such as pumping liquid fertilizers, then the load on the pump will be increased. In
    these cases care should be taken to ensure the engine is operated at lower flows
    to relieve the load. This can be achieved by partially closing an outlet valve.

    • Pumping water containing sand, dirt or other abrasive materials will result in
      accelerated pump wear and mechanical seal failure. Damage of this kind is not
      covered by the guarantee.
    • Never operate the pump against closed head or with no discharge flow as this
      will lead to damage to the pump not covered by the guarantee. If the pump is
      required to operate at no flow then a bypass line should be used to return flow to
      the source or to waste.
    • This pump is not designed to boost high incoming pressure and should not be
      connected to mains or other pressuring water supplies as this may result in
      discharge pressures above the rated casing pressure capacity. Damage to the
      pump from such over pressurisation is not covered by the guarantee.

    The pump should be drained of water or chemicals and normal engine storage
    procedure should be followed. Run the pump until the fuel is exhausted; drain
    the fill the sump with fresh oil. The pump should be stored in a dry place. Before
    starting the pump after storage it should be checked to make sure that it is free to
    rotate by pulling the starter rope with the ignition off.
