The V-20 Diaphragm Vacuum Pump is a compact, oil-free, maintenance-free vacuum pump designed for clean laboratory vacuum applications requiring strong chemical resistance to corrosive gas environments. Featuring a PTFE composite diaphragm, PTFE pump head, and FPM valve construction — the V-20 provides comprehensive chemical resistance across the full range of laboratory solvents and corrosive gases encountered in chemical, pharmaceutical, and analytical laboratory vacuum applications. With 20 L/min maximum flow, 8 mbar ultimate vacuum, a two-stage pump head design for reliable deep vacuum performance, direct electric drive for stable continuous operation, and compact low-vibration construction — the V-20 delivers oil-free, contamination-free vacuum without the maintenance requirements of conventional oil-sealed rotary vane pumps. Enquire about the V-20 today.
The V-40 Diaphragm Vacuum Pump is the general-purpose mid-range model in the V Series — providing higher 35 L/min flow capacity than the compact V-20 while maintaining the same oil-free, PTFE-based anticorrosion construction, 8 mbar ultimate vacuum, and continuous operation reliability. Designed for the broader flow rate requirements of general laboratory vacuum applications — including vacuum filtration of larger sample volumes, medium-size rotary evaporator vacuum supply, chemical processing, and vacuum drying support — the V-40 combines PTFE pump head, PTFE composite diaphragm, FPM valves, direct drive motor, and low-noise low-vibration operation in a compact 170 × 330 × 210 mm footprint at 240W. Enquire about the V-40 today.
The V-65 Diaphragm Vacuum Pump delivers the highest flow rate in the compact V Series range at 65 L/min — specifically designed for demanding laboratory conditions where higher vacuum system throughput, faster evacuation of larger connected systems, or multiple simultaneous vacuum connections require flow capacity beyond the V-40's 35 L/min. Maintaining the V Series' comprehensive chemical resistance through PTFE pump head, PTFE composite diaphragm, and FPM valve construction — the V-65 achieves 8 mbar ultimate vacuum at 400W with a 12 mm interface specification that reduces pressure drop at the pump inlet for high-flow applications. The V-65's direct drive system, quiet low-vibration performance, and continuous operation rating make it the appropriate choice for pharmaceutical process vacuum, high-throughput chemical laboratory filtration, and demanding corrosive gas environments requiring reliable high-capacity oil-free vacuum.

The V-135 Diaphragm Vacuum Pump is the highest-capacity model in the V Series — delivering 125 L/min maximum flow for industrial vacuum systems, large-scale laboratory operations, and continuous chemical processing applications that exceed the flow capacity of compact and mid-range diaphragm vacuum pumps. The V-135 introduces two capabilities unique in the V Series: vacuum adjustment for real-time control of the operating vacuum level, and a real-time display showing current vacuum status — enabling operators to monitor and modify the vacuum conditions of connected processes during operation without external vacuum gauges or manual adjustment. At 600W with PTFE pump head, PTFE composite diaphragm, FPM valves, and continuous operation rating — the V-135 provides industrial-scale clean, oil-free, chemically resistant vacuum for the most demanding laboratory and process environments.
