Calpeda A80 170BA close coupled centrifugal pump 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.
This version with pump casing and lantern bracket in cast iron.
