Jabsco 17936-0001-B Neoprene Impeller, 12 Blade
The Jabsco 17936-0001-B is a genuine Jabsco flexible impeller with a neoprene impeller, supplied as a single impeller kit, bulk packed. It has 12 blades, a 3-3/4 in diameter and a 3-1/2 in width, with a 1 in spline drive, brass insert. As it turns inside the offset pump body, the blades bend and straighten, drawing liquid in and pushing it out, which is what makes a flexible impeller pump self-priming. It is listed for Jabsco 18330 series 2 in electro-magnetic clutch pumps and the 18370-0000 2 in pedestal pump. The impeller itself is Jabsco 17936-0001.
Neoprene is the general purpose compound for water, raw water cooling and mildly abrasive liquids. Impellers are wear parts. Replace one when blades are cracked, torn or have taken a permanent set in the curved position, when the pump is slow to prime, or after it has run dry even briefly. Lubricate the new impeller with a little water pump grease before fitting it, and fit a new end cover gasket or O-ring at the same time.

Frequently Asked Questions
Q: What causes blades to break off?
Running dry is the main cause. Broken pieces can travel downstream and block coolers or strainers, so find every piece.
Q: Should I grease the new impeller?
Yes, a light coat of water pump grease on the blades and hub helps it survive the first dry seconds before liquid arrives.
Q: Can I change impeller compound?
Yes, where the same impeller is offered in another compound for your pump. Choose the compound for the liquid being pumped.
Q: Why is my new impeller hard to fit?
The blades need to fold the right way. A little grease on the blades and turning the shaft in the running direction as you push helps.
