China Water Ring Vacuum Pump Types

There are many types of China water ring vacuum pumps, which can be categorized into SK/SZ series water ring vacuum pumps, 2BV series water ring vacuum pumps, 2BEA/2BEC series water ring vacuum pumps, 2SK series water ring vacuum pumps according to the ultimate vacuum degree, pumping capacity, single-stage or double-stage, and the materials.

The main features of these water ring vacuum pumps are as follows:

SK/SZ Series Water Ring Vacuum Pumps

Features:

1. Compact structure, easy maintenance. The pump and motor share one same shaft.
2. Wide range of applications. It can suction and pump gases that is flammable, explosive, and contains water vapor, small amount of dust, small amount of liquid.
3. It mainly use water as working medium, so the maintenance cost is not much.
4. It can work in the harsh environment.
5. Impeller is usually made of alloy copper or cast iron.

2BV Series Water Ring Vacuum Pump

Features:

The working principle of 2BV series water ring vacuum pump is the same as SK/SZ series water ring vacuum pump. The vacuum degree is generally higher, and the pumping capacity is usually larger than SK/SZ series water ring vacuum pumps. The impeller material is usually stainless steel 304, and stainless steel 316L can be selected according to customer requirements.

2BEA/2BEC Series Water Ring Vacuum Pump

Features:

1. Oil-free lubrication
2. Compact structure
3. Reliable operation
4. Easy to use and maintain
5. Simple structure and easy maintenance.

It is mainly used for pumping gas without particles, the working medium is water at room temperature, and other mediums such as acid and alkali can be used as the working fluid for special requirements, the pumping capacity ranges from 4.8 m3/min-450 m3/min, and the ultimate vacuum degree is 33hpa or 160hpa.

It is widely used in electric power, chemical industry, coal mine, paper making industry, plastic and rubber machinery, environmental protection industry, medical and pharmaceutical industry, food industry, packaging industry, etc.

2SK Series Water Ring Vacuum Pump

Overview:

2SK series water ring vacuum pump is two stage pump.

Because the ultimate vacuum of SK/SZ series water ring vacuum pumps is not high, in order to achieve a higher vacuum and a larger pumping rate under high vacuum, 2SK series vacuum pumps were developed in 1980s in China. It is widely used in the applications like vacuum evaporation, vacuum concentration, vacuum damping, vacuum impregnation, vacuum drying and vacuum smelting for food, textile, chemical, pharmaceutical, metallurgical, electronic field, etc.

Features:

1. High vacuum degree.
2. Large pumping speed while in high vacuum degree.
