Rotary Lobe Pumps
Variety of models: Discover exceptional rotary lobe pumps at Foeth
Rotary lobe pumps are used to move liquids throughout industrial processes. The PD pumps rely on two lobes that rotate around parallel shafts, so the lobes don't make physical contact with each other. Rotary pumps are useful for hygienic processing industries, including biopharmaceutical manufacturing and food processing. At Foeth, all of our positive displacement pumps are mechanically tested to ensure they function as expected. Buying used equipment is cost-effective, and the equipment performs the same functions as new machinery. Let our team help you find the right industrial PD pumps.

How does an Alfa Laval rotary lobe pump work?
Rotary lobe pumps are positive displacement pumps that are capable of handling sensitive materials. They are usually made of stainless steel with steam-in-place and clean-in-place capabilities for superior sanitary qualities and excellent performance. Alfa Laval rotary lobe pumps work similarly to gear pumps. These specialised industrial pumps also use two rotary lobes that rotate in parallel to one another. While doing so, the pump traps a volume of liquid in the chamber. The even rotation of the lobes creates a vacuum effect and continues to pump, forcing the material through the outlet port. Due to the dead spots in the casing, Alfa Laval rotary pumps can be difficult to clean. Plus, you have two sets of mechanical seals to maintain. Unlike other pumps that can be adapted for various functions, lobe pumps are specifically designed for only one industrial application.
What are the advantages of Alfa Laval rotary lobe pumps?
Lobe pump applications are mostly in the chemical, pharmaceutical, cosmetic, and food and beverage industries. Most applications require hygienic pumping and low-shear handling. Rotary lobe pumps don't work well with large solids or abrasive fluids and can reduce flow rates. The main benefit of rotary pumps is that they allow you to move solids suspended in slurries without causing any damage to the product. The gentle pumping action ensures minimal product degradation. Additionally, rotary lobe pumps can handle larger-sized particles that other positive displacement pumps might not be capable of pumping. Since these rotary pumps are efficient for pumping viscous liquids, they offer accurate and consistent fluid output. By adjusting the drive speed, you can also control the flow of fluids.
