SH Scientific Vacuum Pump SH-VDC20

SH Scientific Vacuum Pump SH-VDC20

Product Description

The SH-VDC20 vacuum pump from SH Scientific is a compact oil rotary vacuum pump designed for laboratory applications that require stable and efficient vacuum generation. It provides reliable performance for vacuum drying, filtration, and laboratory systems that need consistent air evacuation.

The pump delivers a pumping speed of 183 L/min and can reach an ultimate total pressure of 5 × 10⁻¹ Pa when the gas ballast is closed. When the gas ballast is open, the pump achieves a pressure of 10 Pa. This gas ballast feature helps manage moisture and condensable vapors, improving stability during vacuum operations.

The SH-VDC20 operates with a single-phase motor rated at 0.37 kW and supports power supply options of 220 V or 110 V at 50/60 Hz. The pump includes KF16 inlet and KF25 exhaust flanges, allowing easy connection to standard laboratory vacuum systems.

Its compact design, efficient oil lubrication system, and relatively low noise level make the SH-VDC20 suitable for continuous operation in laboratory environments. The pump is commonly used with vacuum drying ovens and tube furnace systems.
