CALPEDA A Self Priming Pumps With Open Impeller.

Applications

• For clean or slightly dirty water, also with solids up to 10mm grain size.
• For draining a basin or a sump.
• For irrigation.
• For civil and industrial applications.

Construction

• Close coupled self-priming cenrifugal pumps with open impeller.
• The built in back flow preventer avoids reverse siphoning when the pump is stopped and assures automatic re-priming at the next start.
• The pump re-primes itself even if partially filled with liquid and with completely empty suction pipe.

Operating Conditions

• Liquid temperature up to 90°C.
• Room temperature up to 40°C.
• Maximum permissable working pressure up to 10 bar.
• Continuous duty.
