PoweRupp diaphragm pumps from Tri-Ark can be powered electrically, hydraulically or by air and have no mechanical seals or rotating parts, allowing abrasive slurries to be pumped. As with some air-operated pumps, spill containment chambers are available as an additional option. The power end of PoweRupp pumps is made from cast iron. The wetted end can be provided in cast iron or stainless steel, and diaphragms and check valves can be specified in Neoprene, Buna N, Teflon or Viton. The majority of options are available ex-stock.
