CALPEDA CA Self Priming Liquid Ring Pumps.

Applications

• For clean liquids without abrasives, without suspended solids, non-explosive, non-aggressive for the pump materials.
• If the liquid to be pumped has entrained air or gas or the flow in the suction pipe is not stable.
• For drawing water out of a well.
• For increasing network pressure.

Construction

• Close coupled self priming liquid ring pumps with star impeller.

Operating Conditions

• Liquid temperature up to 90°C.
• Room temperature up to 40°C.
• Total suction lift up to 9m.
• Continuous Duty.
