DSR-VH High Pressure Roots Vacuum Blower Pump

DSR-VH High Pressure Roots Vacuum Pump

Our DSR series roots vacuum pump is pre intake vacuum pump. The vacuum pump is used for absorbing high vacuum.

Dia. meter:                   80-300mm

Air capacity:                 0.5-223m3/min

Vacuum Pressure:        9.8-73.5Kpa

Main Advantages

(1) High vacuum pressure roots type blower, much higher than common roots vacuum pumps.

(2) Air cooling, don't need water cooling system even at high vacuum pressure.

(3) Advanced structure design, low vibration and noise level.

(4) Positive displacement structure, flow rate changes little even pressure changes.

(5) Long service life term, more than 10 years under the guidance.

(6) Adopt a pre intake vacuum technologies, advanced and reasonable structural design.

(7) The impeller adopts a specially designed composite line with high efficiency.

(8) The processing precision of key parts is high to ensure the smooth operation of the vacuum pump.

(9) High vacuum, wide flow coverage.

Roots vacuum pump in petroleum, chemical industry, plastics, pesticides, steam turbine rotor dynamic balance, aerospace space simulation and other devices have been tested for a long time, so it should be vigorously promoted and applied all around the world. It is also widely used in petroleum, chemical, metallurgy, textile and other industries.

Piping Layout

Fixed/mobile vacuum suction and exhaust unit

This device adopts our high-pressure Roots vacuum pump and uses the principle of negative pressure delivery. It operates without dust, with high negative pressure suction, large flow rate, long distance, and high efficiency.

Suitable for high-density materials such as steel sand, aluminum sand, etc.

Suitable for large particle materials, the material diameter can reach 3-5 centimeters.

Suitable for long-distance transportation, with a conveying distance of up to 60 meters.
