Overview

Edwards offers a full range of liquid ring pumps. The LR1B21000 provides a single-stage design and curved blade impellor with reinforcing rings for improved ruggedness, reducing noise and vibration.
 
All of our liquid ring pumps handle wet or dry gases, with high tolerance to liquid carry over. The LR1B 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 28431:1987 and are available as part of ATEX Category 1 and 2 T4 systems.
 
The LR1B21000 is a bare-shaft machine 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, please contact your local office for more complex process system requirements.

Applications

  • The LR1B21000 is ideal for fly ash conveying, pulp and paper, filtration, flue gas desulphurization, methane extraction in mining and chemical and petrochemical applications.
