Rotary lobe pumps are positive displacement pumps that create moving cavities between the synchronised lobes in the pump chamber that move the fluid around the pump chamber. Rotary lobe pumps are one of the most useful types of positive displacement pumps and are particularly wide spread in the food and beverage industry.
Advantages of Lobe Pumps
- Pass medium solids.
- No metal-to-metal contact.
- Superior CIP/SIP capabilities
- Can offer short term dry run capabilities.
- Non-pulsating discharge.
- Can be constructed for hygienic and sanitary applictions.
Typical Applications for Lobe Pumps
Because lobe pumps offer a gentle pumping action and run at low speeds they are good in applications involving solids and high viscosity fluids. This means that they are commonly found in two very different environments.
WHY BUY ROTARY LOBE PUMPS FROM AXFLOW
We specialise in hygienic lobe pumps and large lobe pumps for industrial applications.
AxFlow holds over 1,600 lobe & ECP pumps in stock which us to offer a reliable delivery on bare-shaft pumps of 2-3 days and new pump-sets of under 3 weeks.
To support our pumps in the field, AxFlow holds over 128,152 spare hygienic pump components and kits in stock available on a standard 2-3 or express 24-hour delivery.
We offer three types of rotary lobe pump design.
- Rubber lined lobe pumps for industrial applications.
- Hygienic rotary lobe pumps for low to medium viscosity applications.
- External circumferential piston pumps for more demanding and exacting hygienic duties.
The Waukesha external circumferential piston pump (ECP) design evolved from the traditional lobe pump design. The long sealing path of the winged rotors reduces slippage and offers gentle handling of particulates. They perform better with liquids which require gentle handling, low viscosity, and high viscosity or contain abrasives.
