The Calpeda A-series self-priming centrifugal pumps have an 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.
Flows up to 1100l/min
Heads up to 33 metres
