Beinlich ZPI internal gear pumps
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.
