LZ Series

Gear Pump

High-performance pumps customized to your needs.

Our gear pumps enjoy an excellent reputation due to their solid, high-quality construction and exceptional robustness. They are safe to run dry, self-priming, rotary positive-displacement pumps.

On request, we also supply pumps according to API, ATEX, TR-CU 10, TR-CU 12 and TA Luft standards.

External gear pumps are self-priming and low-pulsation pumps that can run in either flow direction. They are especially suitable for clean, self-lubricating fluids with viscosities higher than water. Gear pumps are not suitable for fluids containing solids or abrasive media. A driving gear and a driven gear work together to pump the fluid. Because of their special design and the double-sided bearing of the gear shafts, gear pumps minimize pulsation and can generate high differential pressures.
