2BEC series water ring vacuum pumps and compressors

Short Description:

Product overview 2BEC series water ring vacuum pumps are usually used to pump the gases without small solid granules, and gases that doesn’t dissolve in water, and noncorrosive gases, so as to form the vacuum and pressure in the closed container. By changing the structural material, it is also available in aspirating corrosive gas or using the corrosive liquid as the operating liquid.

Product overview

2BEC series water ring vacuum pumps are usually used to pump the gases without small solid granules, and gases that doesn’t dissolve in water, and noncorrosive gases, so as to form the vacuum and pressure in the closed container. By changing the structural material, it is also available in aspirating corrosive gas or using the corrosive liquid as the operating liquid. It is used extensively in many trades such as papermaking, chemical industry, petrol chemical industry, light industry, pharmacy, foodstuff, metallurgy and construction materials, stone implement, coal washing, ore dressing and chemical fertilizer etc.

Main application areas

All the bearings are the imported products for ensuring the precise orientation and the high stability during the working of the pump.

The casing is made of steel or stainless steel plates to extend the lifetime of the 2BEA series pumps.

The V-belt pulley (when the pump is driven by the belt) is used the high precise pulley with taper bushing to keep the reliability of the pump and extend its life. And it is also easy to mantle and dismantle.

The coupling is used to drive the pump directly. The flexible part connecting the two half coupling is made of polyurethane that makes the pump more reliable.

The unique design to set the separator above the pump saves the space and decreases the noise efficiently.

All the parts are cast by the resin sands that make the pump surface very smooth. It is not necessary to cover the surface of the pumps with putty and gives out the heat efficiently.

The mechanical seals (optional) are used the imported products to avoid the leakage when the pump works for a long time.
