liquid ring vacuum pumps manufacturer

Shanghai EVP liquid ring vacuum pumps manufacturer specializes in manufacturing and supplying various types of vacuum pump products. We can design and supply vacuum pump solutions according to customer needs.


The liquid ring vacuum pump is equipped with an eccentric rotor with fixed blades. The water (liquid) is thrown to the stator wall. The water (liquid) forms a liquid ring concentric with the stator. The liquid ring and the rotor blade together constitute a variable volume. The pump cavity volume changes to achieve suction, compression and exhaust, so it belongs to variable volume vacuum pump.

liquid ring vacuum pumps manufacturer True Pump Factory is located in Shanghai, mainly R&D design, production and manufacture of a number of series of  liquid ring vacuum pump products, according to customer requirements to design and process various specifications of liquid ring vacuum pump, vacuum pump unit, etc., reasonable price, factory direct sales.

2BV Series Liquid Ring Vacuum Pump

liquid ring vacuum pump features:

Easy to maintain, the temperature of compressed gas is low, the exhaust temperature is only 10 ~ 15 degrees higher than the intake temperature, because of this characteristic, it is very easy to suck pressure to send flammable and explosive gas.

Scope of application: mainly used in coal mine, chemical, pharmaceutical, mining, paper, food, beer, building materials, plastics, metallurgy, electrical appliances and other industries.

Configuration flexible: can be assembled with separators, heat exchangers, pipelines, valves, meters, electronic control devices together on a chassis as a complete set of equipment.

liquid ring vacuum pump manufacturer vacuum pump advantages:

1.the structure is simple, the manufacturing accuracy is not high, and it is easy to process.

2.compact structure, high rotational speed of the pump, usually connected directly to the motor without slowing down. Therefore, with a small structural size, large displacement can be achieved and the floor area is also small.

3.he compressed gas is basically isothermal, that is, the temperature change of compressed gas is very small.

Because there is no metal friction surface in the pump cavity, there is no need to lubricate the pump, and the wear is very small. The seals between the rotating parts and the fixings can be directly sealed by water seals.

4.uniform suction, stable and reliable operation, simple operation, easy maintenance.

In short, because the gas compression in the water ring pump is isothermal, it is possible to remove flammable and explosive gases. Since there is no exhaust valve and friction surface, dust-laden gas, condensable gas and gas-water mixture can be extracted. With these outstanding characteristics, although it is inefficient, it has been widely applied.
