Dimensions, blade profile, hub structure, shaft connection, rubber compound, Shore A hardness, tolerance and packaging must be confirmed by drawing, official specification or physical sample before production.
Rubber impellers for Jabsco 14346-0005 replacement applications are flexible vane pump components used for compatible pump repair, maintenance and fluid handling systems. This page does not assume unconfirmed dimensions, blade quantity, material grade, hardness, color or insert details. Outer diameter, height, shaft connection, hub structure and rubber compound should be confirmed by drawing, official specification or physical sample.
Product Overview
The Jabsco 14346-0005 Rubber Impeller is a 12-blade flexible impeller manufactured from 3A Sanitary Food Grade Neoprene, designed specifically for hygienic flexible impeller pumps used in food, beverage, and pharmaceutical product transfer applications. This impeller fully conforms to stringent hygienic 3A sanitary standards, making it a specialized variant distinct from standard marine engine cooling impellers. It is also produced under the closely related designation 14346-0005B, which uses the same core geometry with a stainless steel double flat key drive insert.

What Is the Jabsco 14346-0005 Impeller?
The Jabsco 14346-0005 is a flexible food-grade Neoprene rubber impeller with 12 curved blades mounted on a double flat drive hub, designed for use in hygienic flexible impeller pumps that transfer food, beverage, and pharmaceutical liquids. As the pump shaft rotates, the flexible Neoprene blades deform and re-expand within the pump housing to draw in and discharge fluid — a self-priming action that provides smooth, steady, and totally pulsation-free output flow. This gentle pumping action does not break down shear-sensitive or fragile liquids, making it well suited to delicate food-grade fluid handling.
Sanitary Design Features
This impeller is engineered specifically for hygienic transfer duty, offering functional advantages beyond standard marine impellers:
- 3A Sanitary Food Grade compliance — fully conforms to today’s stringent hygienic food industry standards for materials in contact with consumable products
- Handles varying viscosities — capable of pumping both low-viscosity and high-viscosity liquids, gels, and pastes
- Solids handling — can pass suspended soft and hard solids with minimal damage to the impeller or the product
- Pulsation-free flow — delivers smooth, steady output without the pulsing common to other pump types, protecting shear-sensitive products
- Fast self-priming — capable of self-priming in as little as 30 seconds on air-tight suction lines
Chemical Compatibility Notes
- Do not pump severe solvents or acids with this impeller
- If any doubt exists about compatibility with a specific product, consult the Jabsco Chemical Resistance Table or contact the factory before use
- If corrosive products are pumped, flushing the pump with water at the end of each work cycle will help prolong impeller life
- Proper marine-grade grease lubrication is recommended during installation to maximize suction/self-priming performance, since the impeller is sensitive to dry running
Related Part Variant
| Part Number | Hub Insert | Notes |
|---|---|---|
| 14346-0005 | Epoxy Plastic Double Flat | Standard hygienic version |
| 14346-0005B | Stainless Steel Double Flat Key Drive | Upgraded metal insert variant, same 12-blade/95mm/63.5mm geometry |
The stainless steel insert (0005B) is generally preferred in aftermarket manufacturing over the OEM plastic insert for improved durability and a more precise shaft drive fit.
Installation & Maintenance Notes
- Dry-running caution — this impeller must never be run dry, even briefly, as the Neoprene blades can overheat and deform without liquid lubrication and cooling
- Lubrication before startup — apply suitable marine grease to the impeller during installation for maximum suction performance
- Recommended replacement interval — follow standard hygienic pump service schedules to maintain sanitary compliance and pumping efficiency
- Flushing practice — flush the pump with water after each work cycle, especially after pumping any mildly corrosive or acidic product, to extend impeller service life

FAQ
Can this product be supplied as a Jabsco 14346-0005 replacement?
Yes, the product can be reviewed as a replacement reference for Jabsco 14346-0005 applications. However, the part number alone is not enough for production approval. Dimensions, blade profile, shaft connection, rubber compound and pump compatibility must be confirmed before manufacturing.
Why are exact dimensions not listed on this page?
Exact dimensions are not listed because no confirmed drawing, official specification or measured sample data has been provided. For rubber impellers, unsupported dimensions can cause installation problems, reduced flow, excessive friction or early blade damage. Confirmed data is required before production.
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, pump chamber clearance and operating conditions should still be confirmed before tooling.
How should buyers select the rubber material?
Rubber material selection depends on the working liquid, temperature, rotation speed, dry-running risk, oil exposure and chemical contact. Buyers should provide the exact media 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 geometry, hub structure or insert design. 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 confirmed dimensions, rubber compound, Shore A hardness, insert structure, tooling status and inspection requirements. Please provide a drawing, official specification or physical sample for review.
