DAB DP Series Self Priming Centrifugal Cast Iron Deep Well Pumps Manual

The DAB DP Series Manual Deep Well Jet Pump is a robust, high-performance solution for drawing water from deep bores, rivers, tanks, and offset wells with static suction depths of up to 27 metres. Built from heavy-duty cast iron for corrosion resistance and long service life, the DP Series is ideal for rural water supply, agriculture, and deep suction irrigation applications.

This manual model offers flexibility to integrate with external pressure systems or controllers and is suited to setups where automatic control is not required or is handled separately. The DP Series is designed for use with DAB Deep Well Injector Kits (sold separately — models E20, E25, and E30 depending on depth and pipe size), making it an adaptable solution for a wide range of site conditions.

Internally, the pump features technopolymer impellers and diffusers, stainless steel adjustment rings, and a carbon/ceramic mechanical seal for efficiency and longevity. The TEFC asynchronous motor is air-cooled and includes built-in thermal overload protection in single-phase versions.

This pump requires a compatible DAB deep well injector kit (E20, E25, or E30) and does not include automatic control. A pressure switch or tank must be added separately for pressure system operation.
