Centrifugal Pump Calpeda AM40 Self Priming Pumps With Open Impeller
Construction
- Close-coupled centrifugal pump with open impeller.
- the built-in backflow 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.
- A: version with pump casing and lantern bracket in cast iron.
- B-A: version with pump casing and lantern bracket in bronze.
- The pump are supplied fully painted.
