IMP1 NBR Rubber Impeller For UP1, UP1-B, UP1-M & UP1/AC Pumps - Bilge Use

Impeller made from special nitril rubber NBR for use with the UP1, UP1-M and UP1/AC models of pump.  This impeller is for use with water and salt water.  The flexible nature of the impeller also means that it can handle an amount of solids in suspension up to a maximum size of Ø5mm.

It is recommended by Marco that the rubber impeller is replaced every season or 500 hours, whichever occurs soonest.  This is to ensure the correct performance of the pump.
