Energy efficient coolant delivery

Screw pumps and gear pumps have internal leak paths that reduce energy efficiency as the pressure increases and as internal wear occurs. They are less efficient when pumping water mix fluids than they are when pumping neat oils as they rely on the higher viscosity of neat oil for internal sealing purposes. 
High pressure cooling is usually carried out with watermix coolants, making Hydra-Cell pumps an obvious choice. 



Independent tests have shown Hydra-Cell to be up to 25% more energy efficient when compared to screw pumps pumping oil emulsions across a wide range of pressures and flow rates and up to 78% more energy efficient than multistage centrifugal pumps pumping emulsion coolant 10 lpm at 40 bar pressure.
