Twin STS B.60 Screw Pumps Application
The STS B.60 is a twin screw pump, with a hygienic design, suitable for use in the food, dairy, beverage and cosmetic industries.
The flow is uniform and in an axial direction, so there are no changes in the volume or physical properties of the product. Therefore, it is an ideal pump for handling shear-sensitive fluids.
It has a high suction lift capability with very low NPSH values.It is capable of pumping liquids with high viscosity, but also with low viscosity, so it can be used as a CIP-supply pump.The design ensures full cleanability and drainability.
Twin STS B.60 Screw Pumps Operation
Twin STS B.60 screw pump is a positive displacement pump what means that the pump is transferring a certain volume of product in accordance with the speed and pitch of the screws. While turning, the two screws are forming closed chambers that are moving in an axial direction.
This movement creates a vacuum at the inlet side and pressure at the outlet. Due to this double chamber technic, there is an almost pulsation free working with high and low viscosity products.
