Principle

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, SLI pumps are well suited for fluids with high or low viscosity, with lubricating or non-lubricating properties, and fluids containing some solid

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 SLI pump can easily be adapted to the user's requirements according to viscosity, temperatures, working pressure, speed and other criteria.

Speeds range from 200 rpm up to 3.000 rpm.
