Quick Answer
The Jabsco 17370-0001 rubber impeller is a flexible vane pump component for replacement, maintenance and fluid handling applications. Dimensions, blade profile, hub structure, shaft connection, rubber compound, Shore A hardness, tolerance and packaging must be confirmed by drawing, sample or official specification before production.
Jabsco 17370-0001 Rubber Impeller with Brass Hub
Product Overview
The Jabsco 17370-0001 Rubber Impeller is a 12-blade flexible Neoprene impeller manufactured as a direct-fit replacement for Jabsco raw-water engine cooling pumps used across a wide range of marine diesel engines. This part number is also listed under the updated designation 17370-0001-P, and while the OEM standard hub is typically plastic/epoxy double-flat drive, a brass-insert version is available and preferred by many aftermarket manufacturers for improved durability and machining precision. It is widely specified for Caterpillar, Cummins, Detroit Diesel, and Doosan marine diesel engine cooling pump applications, making it a benchmark reference impeller across heavy-duty marine engine cooling systems.

What Is the Jabsco 17370-0001 Impeller?
The Jabsco 17370-0001 is a flexible Neoprene rubber impeller with 12 curved blades mounted on a double-flat-drive hub, designed for use in bronze-bodied flexible impeller pumps that circulate raw seawater or freshwater for marine diesel engine cooling. As the pump shaft rotates, the flexible Neoprene blades deform and re-expand within the pump housing to draw in and discharge cooling water — a self-priming action characteristic of flexible impeller pump design. This impeller is the reference part number for numerous heavy-duty marine diesel cooling pump systems and is widely cross-matched by other engine manufacturers and aftermarket impeller brands.
Brass Hub vs. Plastic Hub
While the original Jabsco OEM specification for this impeller uses an epoxy plastic double-flat drive hub, many aftermarket manufacturers produce this impeller with a brass insert instead, for the following reasons:
- Longer service life — the combination of precision fit and material durability results in a more reliable, longer-lasting product versus stock plastic-hub versions
- Superior machining precision — brass machines more cleanly than molded plastic, producing a tighter, more accurate double-flat drive fit to the pump shaft
- Greater durability — brass resists wear, cracking, and fatigue failure better than plastic/epoxy hubs under sustained torque load
- Better heat tolerance — brass maintains dimensional stability at the upper end of the impeller’s rated temperature range, whereas plastic hubs can soften or deform under prolonged heat exposure

Why Neoprene Is Used for This Impeller
- Wide chemical resistance — Neoprene tolerates exposure to fresh water, salt water, and general engine cooling circuit conditions
- Proven temperature range — rated for continuous service between 7°C and 82°C, matching typical raw-water engine cooling circuit conditions
- Industry-standard flexibility — Neoprene remains the most widely used impeller material across heavy-duty marine diesel cooling pump applications
- High blade count for flow volume — the 12-blade configuration increases displacement per rotation, suited to larger-displacement diesel engine cooling demands
Installation & Maintenance Notes
- Dry-running caution — like all flexible impeller pumps, this impeller must never be run dry, even briefly, as the Neoprene blades can overheat and deform without water lubrication and cooling
- Recommended replacement interval — typically every 1–2 seasons or per engine manufacturer service interval, depending on usage intensity and water conditions
- Service kit availability — commonly supplied as a complete kit including a matching gasket and O-ring set for a full service replacement in one part number
- Installation orientation — blade curvature must be installed in the correct rotational direction per the pump housing orientation to ensure proper self-priming function
Applications
- Caterpillar 3406, 3406B, 3406C marine diesel engine cooling pumps
- Cummins VT903M marine diesel engine cooling circuits

FAQ
Can this rubber impeller be supplied as a Jabsco 17370-0001 replacement?
Yes, it can be reviewed as a replacement reference for Jabsco 17370-0001 applications. However, compatibility must be confirmed by drawing, physical sample, pump model or official specification. The part number alone is not enough for production approval.
Why are dimensions not listed on this page?
Dimensions are not listed because they must be supported by a confirmed drawing, measured sample or official specification. For pump impellers, incorrect OD, height, hub size or shaft connection can cause installation failure, low flow or early blade damage.
Can the impeller be manufactured from an old sample?
Yes. A physical sample can be used for reverse engineering when the original drawing is unavailable. The sample should be checked for wear, deformation and blade damage. Critical dimensions and pump operating conditions should still be confirmed before tooling and production.
How should buyers select the rubber material?
Rubber material selection depends on liquid media, temperature, rotation speed, dry-running risk, oil exposure and chemical contact. Buyers should provide the exact working liquid and service conditions. Material selection depends on the application conditions.
Is tooling required for this rubber impeller?
Tooling is usually required for molded rubber impellers with custom blade profiles, hub structures or metal inserts. Tooling cost depends on the drawing and product structure. Prototype samples can be reviewed before batch production.
Are samples available before bulk production?
Samples are available upon request. Sample preparation depends on the impeller dimensions, rubber compound, Shore A hardness, insert structure, tooling status and inspection requirements. Please provide a drawing, official specification or physical sample for review.
