Water ring vacuum pump selection manual

2BE1 water ring vacuum pump selection manual

2BE1 water ring vacuum pump adopts single-stage and single-action structure form, which is an energy-saving product popularized by the country. It is usually used for pumping gases that do not contain solid particles and are insoluble or slightly soluble in working fluid. The vacuum pump generally USES water as the working fluid.

2BE1 water ring vacuum pump has the advantages of simple structure, reliable operation, high efficiency and energy saving, etc. It is the ideal product for vacuum dehydration, vacuum drying, vacuum filtration and pressure delivery in the electric power, petrochemical, coal, paper, tobacco, food, textile, metallurgy and pharmaceutical industries.

Water ring vacuum pump material distribution

The general standard configuration of 2BE1 series water ring vacuum pumps is as follows:

Pump body Carbon steel
Pump cover Cast iron
The impeller Ductile iron or carbon steel
Distribution board Cast iron
Pump shaft material Carbon steel
Mechanical seal High wear resistant ceramic alloys and fluoroelastomers or corrosion and abrasion resistant fillers

The following material configuration can also be selected according to the actual working conditions to improve the performance:

Impeller, distribution plate, pump cover, pump body SUS304(0Cr18Ni9)、SUS316(0Cr17Ni12Mo2)、SUS316L(00Cr17Ni14Mo2)
Pump shaft material 2Cr13、SUS304 or SUS316L
Mechanical seal High wear resistant ceramic alloys and fluoroelastomers or corrosion resistant fillers
Shaft sleeve Cr28 high chromium stainless steel

Water ring vacuum pump performance characteristics

Adopting the latest foreign advanced technology, it has large air volume and high efficiency (working efficiency of 2BE1 series vacuum pumps is up to 60%-70%, and efficiency of SK, 2SK and SZ series vacuum pumps is about 30-40%) and low noise.

Bearing all imported original bearings, to ensure accurate positioning of the impeller and high stability in the process of operation.

The impeller is made of ductile cast iron or welded with steel plate, which ensures the stability of the impeller under various bad working conditions and greatly improves the service life of the  vacuum pump.

The vacuum pump body is made of high quality steel plate, which improves the service life.

As the most easily damaged parts, the company all made of high chromium stainless steel, than the ordinary material life increased 5 times.

Coupling (drive straight al) with a standard high strength elastic coupling, polyurethane (pu) material elastic element, stable and reliable operation, long service life.

Belt pulley (belt drive) adopts standard high-precision cone belt pulley, which runs reliably, has long belt life and is easy to disassemble.

The unique up-mounted gas-water separator not only saves space but also reduces noise.

The mechanical seal is made of high strength ceramic alloy to ensure no leakage during the long operation of the vacuum pump.

The wall profile of the vacuum pump body adopts the approximate ellipse profile to ensure the best vacuum pumping effect.

The over current parts can all be made of sus304/316 stainless steel, used for vacuums with acid and alkali corrosion or higher sanitary grade
