Jabsco 14346-0003 Nitrile Impeller, 12 Blade
The Jabsco 14346-0003 is a genuine Jabsco flexible impeller in nitrile. It has 12 blades, a 3-3/4 in diameter and a 2-1/2 in width, with a 1 in double flat shaft, epoxy plastic hub. 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 30530 and 30570 series stainless steel pumps and 28440 series pump heads.
Nitrile is the compound to choose where oils, fuels or other petroleum products are present, since it resists swelling where neoprene would soften. 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: How long does an impeller last?
It depends on hours, temperature and what is being pumped. Many owners replace it every season or at a set number of running hours as insurance.
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.
