Sell liquid ring vacuum pumps VVN-1,5, WN-3, WN-6, WN-12, WN-25, WN-50

Vacuum, liquid ring pump with BBH Salnikov shaft seals. The pump consists of a cover, a housing, drive bracket, shaft. When the disk rotates, the water under the action of centrifugal force, is thrown to periferie cover, forming a water ring. Between the hub of the working disk and the inner surface of the water ring creates a rarefied environment which provides suction gas through the Crescent-shaped recess in the pump casing. Further rotation of the disc causes compression of the pumped gas. Through a small Crescent-shaped cutout in the housing of the gas and the excess water is discharged into the discharge nozzle of the pump.
Pumps VVN to 0.8 can be used to create a preliminary vacuum to high vacuum installations. Vacuum pumps BBH used in the chemical and oil industry, agriculture, milking installations for drying in paper production and processing of leather, for transportation of dry and liquid products, for drying and sterilization in medicine, plant dust removal at wastewater treatment plants.

Vacuum pump type BBH and the electric pump unit based on it, designed to create a vacuum when working on air or inert gases insoluble in water.
Vacuum pumps with oil seals are designed for pumping air, non-aggressive gases, vapors and gas-vapor mixtures, previously cleared from condensed moisture and mechanical impurities from closed sealed volume in fixed installations placed in the premises, and to generate a preliminary vacuum in a high-vacuum installations.

For example:
Pump WN-0,75 A4.2,
where WN vacuum, liquid ring pump with a nominal suction pressure of 0.04 MPa
0,75 - capacity, m3/min
A4.2 - climatic version and location category
Pump WN-0,8 A4.2,
where 2 is the sequence number modernization;
WN vacuum, liquid ring pump with a nominal suction pressure of 0.04 MPa
0,8 - capacity, m3/min
A4.2 - climatic version and location category
