E2 2" Pumps

Versa-Matic E2 Series Double Diaphragm Pumps

Versa-Matic's E2 2" pump uses the Elima-Matic air valve system to provide non-stalling, lube-free performance. It is available in a clamped or bolted design, with some models offering a side discharge feature that prevents corrosive fluid from leaking onto the pump's center section.

The E2 2" Pump...

  • is available in either plastic or metal
  • avoids blow-by when the pump is online but not in use
  • is self-priming
  • provides dimensional interchangeability with Wilden 2" pumps
  • offers horizontal discharge model on bolted metallic pump
