Technical details

Installation notes

• Replace the impeller when flow drops or the blades show cracks, set or missing pieces.

• Lubricate the impeller and the pump body with a little oil or grease before inserting it.

• Do not run the pump dry: the flexible impeller is cooled and lubricated by the pumped fluid.

• Refit the end cover and check that the impeller rotates freely by hand.
