Description

Double stage rotary vane vacuum pump is the basic equipment used to extract gas from a sealed container to obtain a vacuum. The suction port of double stage rotary vane vacuum pump is connected to the vacuum container or vacuum equipment. During operation, the air in the experimental device will be inhaled and discharged in large quantities to achieve a high vacuum. It can be used alone or as a backing pump for various high vacuum systems and pre-suction pump.

Rotary vane vacuum pump for sale only needs air cooling, with anti-return oil structure which can prevent pump oil from returning into the pumping system, and exhaust filter which can effectively eliminate oil mist, whose working performance is low noise, fast pumping speed, high efficiency and can work under arbitrary pressure.

Double stage rotary vane vacuum pump can be widely used individually in the production of the refrigerator, air conditioner, bulb, fluorescent lamp, bottle; the process of vacuum smelting, vacuum welding, vacuum impregnation, vacuum coating, vacuum heat treatment, vacuum drying.

As a pre-stage pump, a rotary vane vacuum pump for sale can be used before diffusion pump, roots pump, molecular pump in electronic equipment, medical equipment, and other supporting and experimental applications to achieve a higher vacuum environment. Because single stage rotary vane vacuum pump has the advantages of small size, lightweight, and low operating sound, it is more suitable for laboratory use.

Rotary vane vacuum pump manufacturer suggests that we check the pump oil frequently incase the pump will break because it cannot remove water or other liquids. Double stage rotary vane vacuum pump
is equipped with a gas ballast valve to remove out a small amount of condensable steam.

Features of double stage rotary vane vacuum pump

1. Single stage rotary vane vacuum pump has a strong ability to remove water vapor.
2. The oil mist eliminator at discharge port designed by rotary vane vacuum pump manufacturer, which can effectively eliminate the oil mist in the gas discharged by the pump and avoid the pollution to the surrounding environment, which is oil saving as well.
3. Rotary vane vacuum pumps for sale can work continuously under any atmospheric pressure.
4. High pumping speed under low pressure.
5. Rotary vane vacuum pump manufacturer designs built-in automatic anti-oil return valve to prevent pump oil from being back into the system.
6. Air cooling rather than water cooling, which is easy to install, economical, and convenient.
7. Low noise and vibration. Single stage rotary vane vacuum pump is equipped with oil and gas separator, together with oil mist eliminator, constitutes an effective muffler system, which can eliminate exhaust noise and avoid noise pollution.
8. Rotary vane vacuum pump for sale is with compact structure and small size, so it is very suitable for space-saving laboratories.
9. It can be used with various accessories, so it can meet the needs of different applications and makes it the most popular small-sized rotary vane vacuum pump for sale.
10. Double stage rotary vane vacuum pump is suitable for small freeze dryer and forced convection drying oven.
11. Single stage rotary vane vacuum pump is suitable for refrigeration, electronic light bulbs, and other industrial sectors, scientific research, and colleges and universities. They are indispensable basic equipment for various vacuum operation systems.

Advantages of single stage rotary vane vacuum pump

Rotary vane vacuum pump manufacturers designed this series of pumps have the advantages of low noise, no return of oil when the pump is stopped, and easy start-up.

Tips from single stage rotary vane vacuum pump manufacturers

As a single stage rotary vane vacuum pump manufacturers, Hawach reminds customers, single stage rotary vane vacuum pump cannot remove out gas with high oxygen content, explosive, flammable or toxic, corrosive gas containing material experiments, and particulate dust, it also can’t be used as a compression pump or gas pump.
