The Davey K95D469 deep well jet pump is built for drawing water from deeper sources where surface pumps cannot operate effectively. Paired with the 22469 injector kit, this model is designed to suit nominal 4” wells, making it a reliable choice for correctly sized bore installations.
It delivers up to 85 L/Min and reaches a shut-off pressure of 550 kPa, which converts to 56 m head. The system is capable of handling suction depths up to 42 m, providing steady output where consistent pressure is required across varying draw conditions.
The pump uses a jet assisted centrifugal design with a matched deep well injector, combining jet and venturi components to lift water efficiently. An Automatic Demand Response (ADR) valve is built in to help maintain pressure balance and protect the pump from loss of prime during operation.
The casing is made from marine grade aluminium with a Rilsan® lining for added resistance in wet environments. It includes a TEFC motor with IP56 protection and Class F insulation. A pressure switch and gauge come pre-fitted, allowing automatic operation and simple system control.
