LR Series Liquid Ring Vacuum Pumps

For rough vacuum applications in the chemical and allied process industries

Peak performance at low suction pressures

Peak efficiency at high vacuum

The LR range of single-stage pumps are designed for operation across your vacuum range; LR1A right down to 30 mbara; LR1B pumps are optimised for applications at higher pressures above 300 mbara. These pumps include an enhanced bearing design enabling reduced internal clearances for improved efficiency.

Engineered to order

We can help you to meet your process and project specific requirements, using our years of experience to design, engineer, and assemble LR pumps to order.

ATEX versions available

The LR series of liquid ring pumps are available as part of ATEX category 1 or category 2 T4 pump systems. We can supply pumps that are suited to operation in your hazardous environments without the need for flame arrestors.

A choice of configurations

Our Liquid Ring Pumps are offered as standard packages in three basic configurations: Once Through; Partial; Total Re-circulation mode. We can help you to choose the best configuration for your application.

Suitable for a wide range of process industries

The LR1A series of pumps are ideal for the filtration, vacuum forming, general industrial applications, chemical and petrochemical applications.

The LR1B series of pumps are ideal for fly ash conveying, pulp and paper, filtration, flue gas desulphurization, methane extraction in mining and chemical and petrochemical applications.
