Calpeda A40-110BA Centrifugal pump close coupled with open impeller. The built-in backflow preventer avoids reverse siphoning when the pumps is stopped and assures automatic re-priming at the next start. The pump re-primes itself even if partially filled with liquids and with completely empty suction pipe.
This version with pump casing and lantern bracket in cast iron.
