Wanner makes energy efficiency top priority with new coolant pumps
30 Jan 2019
Wanner’s Hydra-Cell high pressure coolant pumps are the most energy efficient, machine tool coolant pumps available, says the company, measured at upwards of 80%, pump shaft to hydraulic power.
The positive displacement pumps maintain this efficiency virtually irrespective of coolant viscosity and system pressure. A Hydra-Cell pump’s flow rate is directly proportional to input shaft speed, enabling a variety of accurate control options to be employed.
With no close internal tolerances, no dynamic seals and no bearings immersed in the coolant, Hydra-Cell pumps are not prone to wear, minimising the need for maintenance and guaranteeing efficiency over a long life.
An added bonus is that the pumps are able to run dry indefinitely with no adverse effects. Filter blocking remains undesirable but in this case is not disastrous.
