Containment Duty Pumps

Containment Duty Non-Metallic Pumps are ideal for highly corrosive and hazardous chemical fluid requirements. All CD duty pumps are exclusively designed with:

  • Containment chambers
  • Hydraulically balanced/coupled pumping diaphragm and driver diaphragm assenblies
  • Designed to accommodate visual, mechanical and low voltage leak detection devices
  • Constructed of Aluminum, Cast Iron, Stainless Steel, Alloy C
  • Constructed of Polypropylene and PVDF with TPE (thermal plastic elastomers)
  • PTFE options in diaphragms and check valves


  • Safe pumping of aggressive, unpredictable, hazardous or toxic liquids
  • Chambers keep accidental spills from entering the air valve
  • Allows the pump to complete the operation in progress before repair has to be done
  • Pumping diaphragms are balanced on suction and discharge stroke
  • Evenly distributed pressure over the surface of the diaphragm gives longer flex life
  • Save money and downtime - protects air valve parts from contamination
  • Longer flex life of the diaphragm means leff frequent routine servicing
  • Solids range +1/4" (6mm) to 3/4" (18mm)
  • Dry primes up to 18 feet of water
  • Free standing support base
