Product Description

Structure and Characteristics

Water ring vacuum pumps and compressors are a new type of high-efficiency and energy-saving product developed by our company based on long-term scientific research, combined with international advanced technology, and continuously verified through practice. They are often used to extract gases that do not contain solid particles, are insoluble in water, and are non-corrosive, to create vacuum and pressure in closed containers. By changing the structural materials, they can also be used to extract corrosive gases and liquids. They are widely used in papermaking, chemical, petrochemical, light industry, pharmaceutical, food, metallurgy, building materials, electrical appliances, coal washing, ore dressing, and fertilizer industries.

The water ring vacuum pump adopts a single-suction single-acting structure, which has the advantages of simple structure, convenient maintenance, high efficiency and energy saving, and reliable operation. Key components such as the pump shaft, impeller, and distribution plate have been optimized in design. Whether it is a ductile iron impeller or a stamped welded impeller, it has undergone good heat treatment. Interference fit hot assembly is carried out before and after balance and dynamic balance checks to ensure smoother operation, better impact resistance, and better adaptability to harsh working conditions such as large drainage volume and load fluctuation impact.

The water ring vacuum pump has a built-in gas-water separator, multiple inlets and outlets, and an exhaust valve inspection window cover added to the pump cover, making installation and maintenance more convenient.

Fluid Material: 304, 316L, 2205, 2507, Titanium

1. The above performance data are based on the conditions of inlet air temperature 20℃, inlet water temperature 15℃, and exhaust pressure 1013hpa.

2. Performance tolerance 10%.

3. The motor power is the commonly used matching power. For special requirements, please contact the technical development department.

4. Some pumps, such as 2BE1-355, can be made with a diaphragm in the pump body. The basic installation dimensions of the pump remain unchanged, and during operation, both sides of the pump body can operate under different inlet absolute pressures.
