Replacement impeller for your Rainman watermaker lift pump.
The lift pump in any of the Rainman pressure supply units contains a small rubber impeller and is considered a consumable item. Life of the impeller will vary with use, but in general you should plan to change it annually.
We offer replacement impellers, but you can equally use Jabsco Profile D 22405-0001-P as replacement. There are also equivalent spec impellers from other brands (Johnson, Volvo, etc.). As they are small and inexpensive, it is worth keeping a spare on hand.
