DP255 SELF-PRIMING JET PUMPS


Applications & Installation

The DP series self-priming deep well pumps consist of an ejector unit and a centrifugal pump connected. The ejector unit can be lowered into a 4" diameter pipe of the well. These pumps are ideal for conveying clean water and non-aggressive fluids. They are highly reliable and user-friendly, suitable for domestic use, automatic water distribution from small to medium surge tanks, and boosting systems. To ensure proper counter-pressure, it is recommended to install a foot valve with a strainer on the suction nozzle.
