Configured for deeper installations where both flow and pressure need to be maintained, the Davey K165D473 is supplied with the 22473 injector and is suited to nominal 4” wells. This combination ensures proper compatibility between the pump and bore size, allowing stable operation across varying installation depths.
The pump delivers a maximum flow of 107 L/Min and develops a shut-off pressure of 620 kPa, equivalent to 63 m head. It is capable of operating from depths up to 42 m, making it suitable for systems where consistent output is required across moderate to high lift conditions.
The system operates using a jet assisted centrifugal arrangement with a matched deep well injector assembly. This configuration enables water to be lifted from below pump level while maintaining steady performance without the complexity of multistage designs.
Construction is based on a marine grade aluminium body with a Rilsan® lining to improve resistance against corrosion and abrasive water. The TEFC motor includes IP56 protection and Class F insulation, and the unit is supplied with built-in control components to support automatic operation.
