Pumps for high efficiency
Published: 18 July, 2019
Thanks to their unique, seal-less design, Hydra-Cell pumps are able to operate at exceptionally high efficiency levels, claims WANNER INTERNATIONAL… And higher efficiency translates directly to ‘lower energy costs’.
The Hydra-Cell pump drive mechanism is submerged in a reservoir of oil, which keeps it permanently lubricated and allows power to be transmitted through the drive train with minimal frictional losses. With no dynamic seals in the pumped liquid to further consume energy, industry leading pumping efficiencies as high as 85% minimise Hydra-Cell’s power requirements.
This compares with around 45-50% pumping efficiency for a typical multi-stage centrifugal pump and, as a result, Hydra-Cell pumps can frequently be fitted with smaller motors than would be needed to meet the same flow and pressure requirements.

WANNER INTERNATIONAL says that although positive displacement pumps are unquestionably more energy efficient than multistage centrifugal pumps, not all positive displacement pumps are equal in that respect.
WANNER INTERNATIONAL has introduced the Hydra-Cell Intelligent High Pressure Coolant Pump that it claims can save machine tool operators up to 70% of their pump energy costs.
WANNER has launched the Hydra-Cell T8030, a Triplex diaphragm pump that it claims eliminates leaks, hazards and the expense associated with replacing seals and packing.
