Jabsco 1133-0003 Impeller Kit, Nitrile
The Jabsco 1133-0003 is a genuine Jabsco flexible impeller kit with a nitrile impeller. The impeller has six blades, a 2 in diameter and a 7/8 in width, with a brass insert for a 1/2 in shaft driven by a pin in a slotted shaft. As it turns inside the offset pump body, the blades bend and straighten, drawing liquid in and pushing it out, which is what lets a flexible impeller pump self-prime. Jabsco uses this part number on specific pump models only, so match it against the parts list for the model number on your pump plate before ordering.
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 the pump 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 at the same time.

Frequently Asked Questions
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: Neoprene or nitrile?
Neoprene for water service, nitrile where oils or fuels are present. Use the compound listed for your pump application.
Q: Which way should the blades bend?
They bend back against the direction of rotation as the impeller is pushed into the body. Turning the shaft in the running direction while pushing makes this easy.
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.
