Construction |
|
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. |
