Proven Pump 3360010 Impeller, High and Low Temperature
The Proven Pump 3360010 is the genuine high and low temperature flexible impeller for the 360 and 365 Series utility transfer pumps. It is the part that does the pumping: a flexible rubber hub with vanes that bend as they pass the cam inside the pump head, opening behind to draw liquid in and closing ahead to push it out. That bending is what makes the pump self-priming, and it is also what wears the impeller out.
Impellers fail three ways, and all three are easy to recognize. Vanes crack or tear at the hub, usually from age and heat; vanes take a permanent set and stay curled, which costs you prime and flow; and vanes shear off completely, almost always from running the pump dry. A flexible impeller is lubricated by the liquid it is moving, so a few seconds without liquid is enough to do real damage. If any vane is missing, find the pieces before you run the pump again, because they travel downstream into whatever the pump is feeding.

Frequently Asked Questions
Q: Why did my impeller lose its vanes?
Almost always dry running. The liquid being pumped is what lubricates and cools the vanes as they flex past the cam, so with nothing in the head the vanes overheat and shear within seconds.
Q: How do I know when to replace it rather than refit it?
Lay it flat and look at the vanes. Any crack at the root, any vane that stays curled instead of springing back, and any set in the rubber means it will not seal against the cam any more.
Q: Does an impeller wear out even in light use?
Yes. Rubber takes a set while the pump sits with the vanes deflected, so a pump used twice a season can have a tired impeller while one in weekly use stays supple.
Q: Should I lubricate the new impeller on assembly?
Wet it with the liquid the pump will handle, or with a little glycerine, before fitting. It makes the impeller far easier to push past the cam and it protects the vanes on the first revolution.
