SH Scientific Vacuum Pump SH-CV20

SH Scientific Vacuum Pump SH-CV20

Product Description

The SH-CV20 vacuum pump from SH Scientific is a compact oil rotary vacuum pump designed for reliable vacuum generation in laboratory and industrial applications. It provides stable pumping performance and efficient air evacuation for systems that require consistent vacuum conditions.

The pump offers a pumping speed of 167 L/min, allowing rapid evacuation of gases from laboratory equipment and vacuum chambers. It can achieve an ultimate total pressure of 5 × 10⁻¹ Pa without gas ballast and 3 Pa when the gas ballast is in operation. This feature allows the pump to handle both dry gases and processes involving moisture or condensable vapors.

The SH-CV20 operates with a single-phase power supply and uses a 3/4 HP motor. The pump includes KF25 inlet and exhaust ports, which allow secure connection to standard laboratory vacuum systems. The oil rotary mechanism is supported by an oil capacity of 0.75 liters, ensuring proper lubrication and stable operation.

Its compact design, efficient motor speed, and relatively low noise level make the SH-CV20 suitable for continuous operation in laboratory environments.
