Water Circulation Vacuum Pump

Water circulation vacuum pump provides vacuum conditions for evaporation, distillation, crystallization, drying, sublimation, filtration, and decompression, degassing and other reaction processes. Considering the small spaces of labs, Water Circulation Vacuum Pump is made with reduced size and one-shot forming.



rotovap pump

Water circulation vacuum pump takes circulating water as the working fluid and uses the fluid jet to produce the negative pressure to eject the vacuum pump. It is especially suitable for the laboratory and small test of chemical, pharmaceutical, biochemical, food, pesticide, agricultural engineering, biological engineering and other industries in colleges and universities, scientific research institutes.

Features of rotary evaporator pump

Apart from features of small size, lightweight and beautiful appearance, water circulation vacuum pump is also upgraded with anti-corrosion performance, longer service life, better reliability, free pollution and low noise.
To suit different requirements of customers, water circulation vacuum pump has a 2-vacuum gauge-2-tap and 4-vacuum gauge-4-tap, which can be used on 1-5L evaporation devices.

For devices with big evaporator volume, you may choose rotovap pumps like multi-usage circulating water pump with 3-vacuum gauge-3-tap, 5-vacuum gauge-5-tap or 10-vacuum gauge-10-tap; or double stage rotary vane vacuum pump, vacuum pump for rotary evaporator, rotary evaporator kit or even molecular vacuum pump with higher vacuum degree.
