Configured with the 22475 injector, the Davey K165D475 is intended for nominal 4” wells where injector selection plays a key role in achieving higher pressure output. This setup is suited to installations where maintaining delivery pressure is more critical than flow volume.
The pump delivers a maximum flow of 25 L/Min and develops a shut-off pressure of 750 kPa, equivalent to 76.4 m head. It is capable of operating from depths up to 42 m, allowing stable performance in systems that require pressure over extended vertical lift.
Its operation is based on a jet assisted mechanism working alongside the pump body. Through a venturi injector system, water is lifted from below the installed level while maintaining controlled and consistent operation under varying demand conditions.
The unit is constructed from marine grade aluminium and internally lined with Rilsan® to improve resistance to corrosion and abrasive water. It is driven by a TEFC motor with IP56 protection and Class F insulation, and comes equipped with built-in components for automatic system operation.
