CONTAINMENT DUTY BALL

ST1½ST1 S20S1F S30 S15

Containment Duty Metallic and 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 assemblies. All containment chambers are designed to accommodate visual, mechanical and low voltage leak detection devices. CD pumps are constructed of Aluminum, Cast Iron, Stainless Steel, Alloy C, Polypropylene and PVDF with TPE (thermal plastic elastomers), PTFE options in diaphragms and check valves.

Containment Duty Pumps additional FEATURES and BENEFITS

Spill Containment

9 o - 1 9 8 o o - 1 r o 8 t a o t i o r o n t a t i o n

•

Safe pumping of aggressive, unpredictable, hazardous or toxic liquids.

•

Chambers keep accidental spills from entering the air valve, protecting plant environment and personnel.

•

Allows the pump to complete the batch or operation in progress, before repair has to be done.

Hydraulically Balanced/Coupled Diaphragms

•

Pumping diaphragms are balanced on suction and discharge stroke.

A A E E

•

Evenly distributed pressure over the surface of the diaphragm gives longer flex life.

Save Money and Downtime

•

Protects air valve parts from contamination, meaning fewer service parts and less maintenance time.

•

Longer flex life of the diaphragm means less frequent routine servicing.
