SH Scientific Vacuum Pump SH-DSV330

SH Scientific Vacuum Pump SH-DSV330

Product Description

The SH-DSV330 vacuum pump from SH Scientific is designed for reliable vacuum generation in laboratory and industrial applications. It offers stable pumping performance and precise control, making it suitable for processes such as vacuum drying, filtration, distillation, and laboratory vacuum systems.

The pump provides a pumping speed of 330 L/min and can achieve an extreme vacuum level of 3 Pa. This capability allows efficient evacuation of gases and vapors from vacuum chambers and laboratory equipment. The unit also supports gas purging using dry nitrogen or dry compressed air, helping maintain stable operation when handling moisture or mildly corrosive gases.

The system is powered by a 1.8 kW motor and uses inverter control to regulate rotational speed between 3000 and 4800 rpm. The integrated PID control function allows stable vacuum performance during operation.

The pump supports analog speed control as well as digital monitoring through MODBUS-RTU communication. These features allow easy integration with automated laboratory systems and remote monitoring platforms. The air-cooled design ensures stable temperature management and reliable operation during continuous use.
