How Do Twin Screw Pumps Work?
A twin screw pump is a positive displacement pump what means that the pump is transferring a certain volume of product in accordance to 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 inlet side and a pressure at the outlet. Due to this double chamber technic there is an almost pulsation free working with high and low viscosity products.To get more news about NETZSCH Pump Accessories, you can visit hw-screwpump.com official website.

Why Choose a Twin Screw Pump?
The twin screw pumps offer a great feature that they can operate over a large speedrange. With this feature, these pumps can have a dual function in hygienic application pumping the product at low speed and the CIP fluid at high speed so No additional CIP pump is needed. Due to the design, the twin screw pump can deliver a pulsation free flow on low viscosity product (<1cP), volatile and gaseous fluids. Also as a result of the design these pumps are able to create a high vacuum causing the pump to be self-priming. The JEC twin screw pump is developed according the highest hygienic specification such as EHEDG and 3A and fulfils the utmost hygienic and efficiency requirements for the most delicate hygienic applications!
Advantages Twin Screw Pumps
