The diaphragm vacuum pump introduces ideal solutions to sample, transfer, or evacuate air and gases. The compact and cool-running pump benefits from a patented structured diaphragm promoting optimized pneumatic performance and long service life. The pump can suit a wide variety of process, laboratory, or OEM applications ranging from large-scale rotary evaporators and continuous/manifold filtration systems to process control sampling. Customization capabilities expand their application potential to many other areas. The pump features standard specially engineered multi-port valves to tolerate condensation without damage, perform oil-free transfer with uncontaminated flow and minimal maintenance, and run quietly with low vibration. They can achieve enhanced gas tightness with leak rates as low as 6 x 10-3 mbar L/s, deep vacuum potential of 2 mbar, and flows as high as 110 L/min. Pumps can be equipped with standard AC motors or explosion-proof AC versions for compliance with Class 1, Division 1, Groups C & D hazardous locations. Single- or doubled-headed pump options can also be specified. Wetted material choices range from economical aluminum heads and EPDM diaphragms to solid glass-filled PTFE heads and PTFE diaphragms, which offer higher resistance to corrosion and chemicals.
