Liquid ring vacuum pump EDWARDS

LR Single and Two Stage Liquid Ring Pumps

The Edwards single and two stage liquid ring vacuum pumps provide the optimum solution for many rough vacuum applications in the chemical and allied process industries. Single stage liquid ring pumps are suitable for continuous operation on pressure from atmosphere down to 100 mbar, while the two stage configuration offers greater efficiency at low pressures. Both configurations can handle wet corrosive process streams and are tolerant of particulates while offering minimal maintenance requirements, vibration and noise.

LR1A Liquid Ring Pumps :

The LR1A Series of Liquid Ring Vacuum Pumps provide a single-stage design and curved blade impellor with reinforcing rings for improved ruggedness, reducing noise and vibration. Capable of handling wet or dry gases with a high tolerance to liquid carry over, the LR1A Series has an enhanced bearing design enabling reduced internal clearances for improved efficiency.

Pumps are available in cast iron and 316 stainless steel construction as standard with other materials and corrosion-resistant coatings available. All are tested to DIN 28431:1987and are available as part of ATEX Category 1 and 2 T4 systems.

The LR1A pumps are bare-shaft machines and can be supplied as part of a standard package, incorporating electric motor, base-plate and seal liquid recovery system, suitable for once through, partial or total recirculation. Custom-engineered packages are also available.
