Versamatic distributor Germany – air-operated diaphragm pumps for tough media
As Versamatic distributor Germany we supply air-operated double diaphragm (AODD) pumps for media where centrifugal pumps fail: solids-laden slurries, highly viscous adhesives, aggressive acids and alkalis. Versamatic pumps run dry, are self-priming and can be dead-headed without damage.
Why compressed air instead of an electric motor?
- Intrinsically safe: no ignition source, therefore usable in ATEX zones without elaborate motor protection
- Infinitely adjustable: flow controlled via air pressure and throttling, no frequency inverter needed
- Solids-capable: ball valves pass particles that would block any impeller
- Service-friendly: diaphragm change in the field without dismantling pipework
Combining materials correctly
Housings in polypropylene, PVDF, aluminium or stainless steel are combined with diaphragms in Santoprene, PTFE, EPDM or Neoprene. PTFE is chemically almost universally resistant but stiffer and therefore less suction-friendly; Santoprene offers the longest service life with aqueous media. We match the combination to your medium and state the expected service life openly and realistically.
- Record medium, solids content and grain size
- Determine flow rate and back pressure
- Check air consumption against available compressor capacity
- Define housing and diaphragm material
- Add accessories: pulsation damper, leak detection, foot valve – ranges and technology are shown in the air-operated diaphragm pumps category
