Diaphragm Vacuum Pump – LMVP20 / LMVP40 / LMVP60 (20–60 L/min Flow Rate | Oil-Free Two-Stage Pump | PTFE Coated Head)

LMVP20, LMVP40 and LMVP60 Diaphragm Vacuum Pumps are oil-free vacuum pumps designed for laboratory and industrial applications requiring clean and maintenance-free vacuum generation. Operating with a flexible diaphragm mechanism, these pumps provide suction and compression without the need for lubricating oil, eliminating contamination risks.

The pumps feature a two-stage design with PTFE-coated pump heads and FPM valve materials to provide excellent resistance to corrosive chemicals and aggressive vapors. Low vibration operation, direct motor transmission and built-in overheating protection ensure stable and reliable performance during continuous operation.

Available with flow rates of 20 L/min, 40 L/min and 60 L/min, the LMVP series is widely used with rotary evaporators, vacuum filtration systems, vacuum drying applications, distillation processes and gas transfer operations. The compact design and pollution-free operation make these pumps suitable for pharmaceutical, chemical and research laboratories.
