Data sheet

Close-coupled centrifugal pumps 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 lanter bracket in cast iron.
B-A: version with pump casing and lanter bracket in bronze (the pumps are supplied fully painted).
