The C920ZF high power chemically-resistant diaphragm vacuum pump from Wiggens is resistant to acid, base and solvent vapours as well as to high and low temperatures. All vapour contact materials of this tightly-sealed unit are constructed of PTFE and the instrument features overheating protection to prevent damage to the pump. The C920ZF can achieve flow rates of up to 75 L/min and a maximum vacuum down to 8 mbar.

The C920ZF pump is direct-driven from the motor so there is no belt-driven transmission. This reduces both instrument vibration and noise.
