Rotary Lobe Pumps

Rotary Lobe Pumps for Precise Fluid Transfer

Rotary lobe pumps are similar in design to gear pumps, utilising two Y or I-shaped lobes that rotate within a pump casing. The precise timing of these lobes is controlled via a gearbox and timing gear, ensuring that the lobes do not make direct contact with each other, promoting smoother operation.

As the lobes rotate, they create a vacuum that enables the pump to be self-priming up to 6 metres and handle gas slugs effectively. The rotating lobes form cavities that draw in liquid, which is then transported through the pump casing towards the outlet and expelled. Notably, the liquid flows between the lobes and the outer casing, not between the lobes themselves, ensuring that the fluid remains unaltered during the transfer process.

This unique design allows for precise fluid transfer, with minimal disruption to the product being pumped. The inlet and outlet ports of rotary lobe pumps can be configured horizontally or vertically, giving them flexibility for various installation requirements, making them an ideal choice for both compact and large-scale setups.

With reliable self-priming capabilities, the ability to handle gas-liquid mixtures, and precise fluid control, rotary lobe pumps are well-suited for applications in industries such as food and beverage processing and chemical transfer. Their unique operating principle ensures consistent fluid movement and makes them an excellent option for applications that require accuracy and reliability.
