Internal-gear pump ZPI

for coolantstationaryfor petrochemical applications

Internal gear pump ZPI Thanks to internal gear wheels, the gear pump ZPI allows an especially low-noise conveying of the fluid which not only reduces the noise emission but also the costs for noise-absorbing measures. Furthermore, the high volumetric efficiency of the ZPI internal gear pump has a positive effect on the energy balance due to the improvement of the overall efficiency.
