Shear Sensitive Liquids

Hydra-Cell® delivers a low shear pumping action, even at high pressure.

Extensive customer testing on shear sensitive liquids, such as polymers, algae solutions, food oils and milk from 50 to 3,500 cP, have proved that the Hydra-Cell's pumping action achieves the lowest shear, especially in high pressure applications, testing up to 200 bar.

Shear is imparted to a liquid when the velocity gradient through the liquid is large. This can be high when there is a moving surface travelling over a stationary surface. If shear is high enough it can break down the structure of the liquid changing it’s properties. For example in algae suspensions used in bio fuel production.

The gentle pumping action of the Hydra-Cell pump helps to reduce shear and improve processing.
