ZH/ZV Blue Series


A high performance pump customized to your needs

With our diverse standard and high performance gear pump range we are able to serve all your needs and respond to any challenge. Our gear pumps are robust, self-priming and are designed for your specific application.

On demand, we can provide external gear pumps which API, ATEX, TR-CU 10, TR-CU 12 and TA Luft compliant.

External gear pumps are self-priming, non-pulsating and reversible pumps that work best on clean, lubricating fluids with a viscosity thicker than water. Two gear teeth, one idler and one driver, mesh together to transfer the liquid.

Because of the balanced construction and bearings on both sides of the shafts, the pumps are capable of non-pulsating flow and high pressures.
