This pump is part of the Containment Duty Pumps. It is specially fitted with PTFE diaphragms as well as elastomeric or elastomeric/PTFE driver diaphragms. The liquid-filled spill chambers provide an additional chemically-resistant barrier, should a pumping diaphragm fail. The Spill Containment design gives the pump user advanced warning of diaphragm failure, before pumpage can damage the air valve or be released into the work environment. Three optional leak detectors available for this model:
  • Mechanical VIP Leak Detector 031-025-000
  • Electronic Leak Detector (115V) 032-043-000
  • Electronic Leak Detector (220V) 032-043-000
The Containment Duty pumps offer many different levels of materials and spill monitoring devices designed to fit a variety of applications and budgets.
