hp-Technik UHE-A2-PZ-I-4-20 oil pump

Technick UHE-A2-PZ-I-4-20 pumps are internal gear pumps. They have an integrated overflow valve. The flow rate for normal fuel oil at 20 °C (6 cSt) and motor speed of 2800 min -1 is max. 1300 l/h. The pressure range where the pump works depends on the chosen pressure stage. It ranges between 1 – 40 bar.

An internal geared rotor drives an eccentric mounted outer geared pinion. The pumping medium will conveyed between the tooth gaps of the two gears. For this purpose the conveyor rooms are sealed by a cap with an integrated crescent.

hpTechnick UHE-A2-PZ-I-4-20 pumps are intended for transporting heating oils. Where other media has to be transported, this must be verified by the manufacturer. Otherwise, the pump’s service life may be decreased.
