How does a lobe pump work

Can handle larger sized particles than may be pumped with other types of positive displacement pumps. May be easily cleaned using either clean-in-place CIP or steam-in-place SIP methods, making them ideal for hygienic processing applications. Highly efficient for pumping very viscous liquids. Offer accurate and consistent fluid output that is unaffected by changes in head pressure, assuming sufficient fluid viscosity.

The fluid flow can be increased or decreased by controlling the drive speed. Generally easy to maintain. Alfa Laval SX Series. The two sets of mechanical seals used in lobe pumps adds to the cost of maintenance and overall ownership. The design of lobe pumps requires the use of pressure release and safety bypass valves, adding to their complexity. The efficiency of lobe pumps is compromised when pumping low viscosity fluids. Slip is the amount of fluid that flows back from the discharge side of the pump to the suction side of the pump during normal operation.

Then, as the discharge pressure of the pump increases, slip will increase as well because the pump is working harder to move fluid from the suction side of the pump to the discharge side and out.

Rotary lobe pumps offered by CSI There are a number of global manufacturers of rotary lobe pumps, and CSI is proud to represent two companies, Alfa Laval and Ampco , which provide premier products for hygienic processing applications.

Alfa Laval rotary lobe pumps OptiLobe Series Developed for general applications in the dairy, beverage, food, home, and personal care industries, OptiLobe pumps combine cost-effective simplicity and easy maintenance with Alfa Laval quality and reliability.

SRU Series Designed for wide ranging applications in the brewing, dairy, food, pharmaceutical, and chemical industries, SRU pumps can handle low to high viscosity media including creams, gels, cells, and organic solids in suspension ; are suitable for CIP ; and conform to 3-A sanitary standards.

Ampco rotary lobe pumps AL Series These pumps combine ease of maintenance, CIP performance, and reliability with economical pricing, and are suitable for a variety of food, dairy, beverage, and pharmaceutical applications. A Guide to Choosing the Right Pump for Hygienic Applications This guide is intended for engineers, production managers, or anyone concerned with proper pump selection for pharmaceutical, biotechnology, and other ultra-clean applications.

Contact CSI. As the rotors pass the suction port, the cavity generated increases creating a pressure decrease, which induces the pumped medium to flow into the rotor case. The core benefits of using a lobe pump are the perfect cleaning capabilities, the ease of maintenance and the extended life time thanks to the improved construction. Lobe pumps mean reliable and safe pumping of food and pharma related fluids. Phone number. Company name. Privacy conditions.
