The pumped fluid flows through the screws in an axial direction. Therefore, the pump imparts very low shear and little pulsation to viscous and shear-sensitive products. For this reason, SLH pumps are well suited for fluids with high or low viscosity, with lubricating or non-lubricating properties, and fluids containing some solids. The entrance geometry of the suction chamber is modified to accommodate the particular fluid properties of the product, thus allowing the pump to handle applications with liquid, lumpy and abrasive fluids.

The SLH Pump can easily be adapted to the user's requirements according to the viscosity, temperatures, working pressures, speed and other criteria. Speeds range from 100 rpm up to 3.600 rpm.

 With this wide range it is possible to operate the SLH not only on normal process sequences, but also cleaning and CIP operations as well, using only one pump..

... E. g.: Fruit stays whole
