LRF Type (single stage)

LRF pumps is the new generation energy saving product. It is generally used for handling solids free gases which can be dissolved or just slightly dissolved in the working liquid.

LRF vacuum pumps usually utilize water as working liquid. Innovative hydraulics achived by optimizing the wetted ends, resulting in higher efficiency when operated at 200-1013 mbar in particular. 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.

Wide applications of LRF liquid-ring vacuum pumps:

• negative pressure dedusting in power industry,
• vacuum distillation, vacuum crystallizing in petrochemical industry,
• aerospace industry (aerological simulation),
• vacuum systems and de-aeration in Paper making industry,
• varying adsorption in gas making,
• vacuum floation and filtration in fuels sector and mine,
• Methane removing from coal bed in coal mine.
