The LMVP20 Diaphragm Vacuum Pump is an oil-free, two-stage vacuum pump designed for laboratory and industrial applications where reliable vacuum generation and resistance to chemical corrosion are important. It delivers a 20 L/min flow rate at atmospheric pressure and achieves a final vacuum of 8–15 mbar absolute.

The LMVP20 incorporates a PTFE-coated pump head and diaphragm, providing high resistance to chemical corrosion. Its low-vibration direct-drive motor, overheat protection and automatic temperature cooling/stability features make it suitable for demanding laboratory vacuum applications.
