    Davey 125D Deep Well Jet Pump

    Rugged, reliable single stage centrifugal pumps with deep well injectors, driven by Davey’s TEFC motor. Pump fitted with pressure switch for easy conversion to automatic operation. Automatic demand response valve fitted as standard to protect against loss of prime from over pumping. A deep well jet pump combines two principles of pumping – that of the centrifugal pump and that of an injector (nozzle and venturi assembly). Davey’s range of deep well pumps are fitted with a pressure switch for easy conversion to automatic operation. An automatic demand response valve (ADR) is fitted as standard to protect against loss of prime from over pumping.

    Used in conjunction with Deep Well injector kits, these pumps are ideal for supplying high pressure water from bores to 42m depth for:

    • Water supply
    • Tank filling
    • Stock watering
    • Sprinkler supply

    Pumps can also be used in applications where the pump needs to be horizontally offset from the water supply.
