Neoprene 6-blade impeller

An impeller is a key component of water pumps, especially in marine applications. It consists of flexible blades (here, 6 blades) that rotate inside a pump body to create fluid movement. The neoprene impeller is specifically designed for pumping fresh and saltwater, as well as for engine cooling systems, thanks to its resistance to abrasion and common chemicals in the marine environment.

This impeller has the following dimensions:

Outer diameter (Ø B): 51 mmShaft diameter (Ø A): 12.7 mmThickness (C): 22 mmHub type: Brass insert

Neoprene is a synthetic elastomer material known for its good resistance to abrasion, seawater, and many chemicals, including small amounts of oil or diesel fuel. These properties make it an ideal choice for marine pump impellers, ensuring reliable durability and performance in harsh conditions.

This Jabsco impeller has 6 blades, a common configuration that provides a good balance between flow rate and priming capability for water pumping applications.

Yes, this neoprene impeller is perfectly suited for pumping fresh water and seawater. Its neoprene composition provides excellent resistance to corrosion and wear caused by the marine environment.

Yes, the neoprene impeller is designed to tolerate small amounts of oil or diesel fuel without significant damage. However, prolonged exposure or high concentrations should be avoided to preserve its optimal lifespan.

The Jabsco manufacturer part number for this impeller is 22799-0001B.

The standard packaging for this Jabsco impeller typically includes the impeller itself. The seals or gaskets required for installation are often sold separately or included in pump-specific maintenance kits. Check your pump’s specifications to determine if additional seals are needed.

This impeller is designed to fit a pump shaft with a diameter of 12.7 mm (Ø A).

Although physical dimensions (outer diameter, shaft diameter, thickness) are crucial, other factors such as hub type (brass insert here) and material flexibility can vary between brands. For optimal performance and durability, it is strongly recommended to use an impeller from the brand and model specified by your pump manufacturer. Using a non-original impeller, even with similar dimensions, could affect the pump's efficiency or lifespan.

Yes, this neoprene impeller is specifically designed and widely used in marine engine cooling systems. Its resistance to seawater and temperature variations makes it a reliable choice for this critical application.

To identify your impeller, check the reference engraved on the impeller hub if it is still legible. If not, precisely measure the outer diameter, the shaft diameter, and the thickness of your old impeller. Compare these measurements with the specifications of the Jabsco 22799-0001B impeller (Ø A: 12.7 mm, Ø B: 51 mm, C: 22 mm). It is also useful to consult the maintenance manual for your pump or engine, which will indicate the exact reference for the replacement impeller.

To replace an impeller, you will generally need the following tools:

A wrench or screwdriver to open the pump cover.A fine-nose pliers or a specific impeller extractor (for difficult models).A bit of lubricant (glycerin or liquid soap) to ease the insertion of the new impeller.A clean cloth.

Yes, it is strongly recommended to lightly lubricate the new impeller and the inside of the pump housing with soapy water, glycerin, or a water-based lubricant before installation. This makes inserting the impeller easier without damaging the blades and aids in the initial priming of the pump.

During installation, ensure the engine is off and the pump is isolated from the circuit. Clean the impeller housing thoroughly and check the condition of the cover gasket. Insert the impeller while slightly turning it in the direction of the pump's rotation so the blades bend correctly. Tighten the cover evenly to prevent leaks.

To remove a used impeller, cut the pump’s power supply. Remove the pump cover. Use needle-nose pliers or an impeller puller designed for this purpose to grip the impeller hub and gently pull it out of its housing. Avoid forcing or using tools that could damage the pump shaft or pump body.

Impellers are wear parts subjected to significant stress during operation. As consumables, they typically carry a limited warranty covering manufacturing defects only, not normal wear from use. Regular inspection and preventive replacement are essential to avoid more severe damage to the pump or motor.

Several signs can indicate that an impeller is worn and needs replacement:

Reduced water flow: The most common sign of a failing impeller.Overheating of the engine: If the impeller is part of the cooling system.Abnormal vibrations or noises: May indicate damaged blades or imbalance.Visual inspection: Cracked, torn, deformed, or missing blades.Water leaks around the pump: May be linked to a damaged seal due to impeller failure.
