SH Scientific Vacuum Pump SH-WV20

SH Scientific Vacuum Pump SH-WV20

Product Description

The SH-WV20 vacuum pump from SH Scientific is a water circulation vacuum pump designed for laboratory applications requiring stable and continuous vacuum generation. It utilizes circulating water as the working medium to create vacuum pressure, making it suitable for laboratories that require reliable and environmentally friendly vacuum systems.

The pump can achieve a maximum vacuum degree of 25 mmHg (torr) or -0.098 MPa and delivers a pumping speed of 20 L/min. Its design includes a built-in water bath with a 15-liter capacity, which supports stable circulation and continuous operation during vacuum processes.

The system is equipped with two taps that allow simultaneous vacuum supply to multiple instruments. Each tap can provide an air suction amount of 10 L/min, with a total suction capacity of 20 L/min. An external circulation nozzle is also included, allowing the pump to support circulation applications when connected with a silicone tube.
