(Twin) Screw Pumps
What are screw pumps? Screw pumps belong to the positive displacement pump principle and use one, or more, screws to move fluids or solids along the screw(s) axis. Historically, the pump was invented by Archimedes for transferring water on the field to a higher level. Nowadays, we use this pump in many hygienic applications like food, diary, beverage, cosmetics, pharmaceutical and chemical applications.

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.
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 Packo 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!
Applications Twin Screw Pump
- To pump structure sensitive products
- Pumping fluids with solids
- Multiple use, operate at low capacities with low RPM's and high RPM’s for CIP cleaning
- For applications where high viscous products, as well as low viscous products need to be pumped under high pressure.
- Applications where you need a pulsation free flow
Advantages Twin Screw Pumps
✔ Flexible for various conditions at the best operating: from high to low viscous liquids
✔ A 2 in 1 pump: high speed range (up to 3,000rpm) of revolution ensures “2-in-1” operation for both products and CIP.
✔ Pulsation free for gentle treatment and high suction performance
✔ Out shimming located between gearbox and casing reduces a lot of time-consumed rotor’s alignment.
✔ 3-A & EHEDG certified and elastomers with FDA & EC1935/2004 complied.
✔ Integral geared adaptor can be coupled with B5, 4pole motor directly.
✔ Simple & easy maintenance with low service cost.
✔ Fully drainable front cover.
