Pumps for shear sensitive liquids

As soon as the liquid leaves the vessel and enters the suction piping, it begins to shear as the liquid traveling through the middle of the pipe moves in relation to the pipe walls. Rotary pumps impart more shear between the rotating elements and the stationary casing.

As Hydra-Cell pumps have no rotating elements in contact with the pumped liquid and no tight internal tolerances, they impose minimal tangential stress to cause shear.
