Self-priming monobloc centrifugal pumps with open impeller.

An anti-back-suction device built into the suction bell prevents back-suction when stopped and re-suctions every time it is turned on.

The pump is self-priming even if it is partially filled with liquid and the suction pipe is completely empty.
