At Alflow, we sell screw pumps – also called screw spindle pumps and double screw pumps – for the pharmaceutical industry, for the chemical industry and for the food industry. The pumps are produced in durable materials that help ensure an efficient experience. See the selection of screw pumps from leading manufacturers on this site, and transport the particular fluids in the best way.
What is a screw pump?
Screw pumps, which are positive displacement pumps, are suitable for pumping extremely liquid and highly viscous products. They deliver a gentle and pulsation-free pumping of liquids with high suction power.
The screw pump moves the medium with the help of the double screws, which rotate and thus push the medium forward from the suction side towards the pressure side. This achieves a uniform and delicate flow without pulsation. The contact-free movement of the screws also eliminates the risk of wear particles in the medium.
Screw pumps are known for their versatility and are available in different models in AISI 316 stainless steel, cast iron, Inconel, Hastelloy, nickel-aluminium bronze, Duplex and Super Duplex.
Find the right screw pump for your process
A screw pump can of course be used for several different purposes. We have mentioned below, some of the places where you can use a screw pump:
- Process and chemical manufacturing
- Food production
- Beverage production
- The pharmaceutical industry
- Cosmetics manufacturing
Our sanitary screw pumps are high-performance and hygienic double screw pumps for sanitary applications that also ensure gentle treatment of the product. Whether the medium is aqueous, highly viscous, lumpy, fibrous or gaseous, it is suitable for all types of media with virtually any consistency.
With our sanitary screw pump, you get product and CIP in one pump, as the pump’s low moment of inertia on the screws means it can handle both product and CIP. There is thus no need for a separate CIP pump.
Our sanitary screw pump is also available as a hopper model or as a double-flow model.
The hopper is the effective solution for non-liquid media. It is fitted with a funnel just above the screws, which allows the screws to catch even the most problematic product.
The double flow model is custom made with double inlet and single outlet, allowing to run very high pressures.
Our industrial twin-screw pumps are powerful positive displacement pumps that provide pulsation-free pumping of media with a high suction capacity and low NPSHr. They are self-priming, have a low noise level and low vibration.
They are designed and manufactured in a modular format, so that it is possible to replace spare parts. This way you achieve low operating costs and longer maintenance intervals.
Fluids for screw pumps
The screw pump is versatile and designed to handle both thin and very thick liquids, including much abrasive and corrosive media. An added advantage is the ability to handle liquids containing fibres or solid materials in suspension. For example, it is compatible with:
- Dairy products
- Cream cheese
- Fruit juice
- Blood plasma
- CIP fluid
