Jabsco 5915-0001-P Flexible Neoprene Impeller Kit for High-Pressure Applications

The Jabsco 5915-0001-P is a specialist neoprene impeller kit identified by Jabsco as a high-pressure option in its 777-series pump documentation. Its eight-blade impeller uses a brass splined hub. This is an application-specific service part, so selection should follow the pump requirements rather than a general comparison with standard cooling impellers.

Technical Data & Parameters

• Nominal shaft diameter (C): 16 mm
• Drive type: Spline drive
• Insert material: Brass

Choosing the Correct Replacement

Jabsco advises consulting the factory for application recommendations when using this high-pressure option. Confirm that 5915-0001-P is specified or approved for the installed pump and operating duty before ordering. An impeller alone does not establish a safe pressure or flow rating for the complete pumping system.

Similar Impellers: What to Check

The nominal 65 mm diameter, 51 mm depth and 16 mm spline size resemble other Jabsco impellers. Those measurements do not establish equivalent operating suitability. Do not treat 5915-0001-P as an automatic upgrade for every pump using a similarly sized 920 or 17937 impeller.

Application & Compatibility

Jabsco lists 5915-0001-P as an optional high-pressure neoprene impeller in the 777-series manual. The manual directs users to obtain application recommendations. Check the complete pump model, fluid, speed and pressure requirements together.

Service Kit Selection

This listing is the packaged -P impeller version. Match any supplied gasket or seal to the fitted pump and use only the correct end-cover sealing arrangement. An impeller service pack is not a complete pump overhaul kit: inspect the shaft, cam, cover and seals separately, and order additional worn parts as required.

Why Choose This Impeller?

• Correct replacement specification: The 8-blade configuration and spline drive help identify the required service part.
• Neoprene for water duties: Suitable for fresh and salt water applications where approved for the pump.
• Serviceable component: Replacing the impeller allows a compatible pump to be maintained without automatically replacing the complete assembly.

Installation & Maintenance

Follow the fitted pump's service instructions. Isolate its drive and close the relevant seacock before opening it. Remove the old impeller with a suitable tool, inspect the chamber for wear and recover any missing blade fragments. Fit the correct cover gasket or seal and lubricate the replacement with an installation lubricant approved for the pump and neoprene.

Restore the water supply before starting, then check for leaks and normal water delivery. Avoid dry running. Include the impeller in routine servicing and keep a matching spare available for essential onboard systems.
