LRE Type (single stage)

LRE pumps are designed for pumping large volumes of vapor-air mixture. The pump shaft with impellers is located on two support bearings. There are shaft end seals on both sides of the pump. For different applications, the type of shaft seal, as well as the shut-off fluid supply systems, may vary.

The pumps are certified according to the Technical Regulations of the Customs Union 010/2011 and 012/2011 for operation in explosive zones.

On the basis of liquid-ring vacuum pumps, vacuum installations can be assembled, designed exactly for the process and equipped with a liquid-separator separator, heat exchanger, shut-off and control valves, control and measuring devices and automation and other components.

Main applications of LRE liquid-ring vacuum pumps:

• chemical and petrochemical industries (vacuum distillation, evaporation, crystallization, dehydrogenation processes),
• power engineering (pumping of steam-air mixture from turbine condensers, deaeration processes),
• aerospace industry (aerological simulation),
• as part of sterilizers and autoclaves,
• pharmaceutical and textile industries,
• pulp and paper and mining and processing enterprises.
