Quick Answer
The JMP 810-01 rubber impeller is a flexible vane component for marine pump replacement, seawater circulation, engine cooling and fluid transfer applications. 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.
The JMP 810-01 rubber impeller is a flexible vane pump component used as a replacement reference for marine pump service and fluid handling applications. This page does not assume unconfirmed dimensions, material grade or insert details. Outer diameter, height, blade profile, shaft connection, rubber compound and hardness should be confirmed by drawing, official specification or physical sample.
Product Overview
The JMP 8101-01 Rubber Impeller is a 12-blade flexible impeller manufactured to JMP Marine’s proprietary rubber compound formula, engineered specifically as a direct replacement for JMP’s own multi-purpose marine pump line. It is used in the JPR-VK2000 pump — a general multi-purpose pump designed for a wide range of liquid transfer, circulation, and processing applications including bottling systems, cleaning solutions, sewage treatment, and marine seawater use. This impeller reflects JMP Marine’s decades of proprietary rubber compounding experience, marketed as delivering significantly longer service life than standard Neoprene or Nitrile impellers used by other brands.

What Is the JMP 8101-01 Impeller?
The JMP 8101-01 is a flexible 12-blade impeller mounted on a double-flat-drive hub, designed for use in the JPR-VK2000 general multi-purpose pump. As the pump shaft rotates, the flexible blades deform and re-expand within the pump housing to draw in and discharge fluid — a self-priming action that allows the pump to lift fluid dry up to 3 meters, and up to 9.5 meters when primed wet. This makes it well suited to bilge, deck wash, and general liquid transfer duties beyond standard engine cooling applications.
JMP’s Proprietary Rubber Compound
JMP Marine has developed a rubber compound formula over more than 40 years of experience specifically engineered for seawater and raw water applications. This proprietary mixture is positioned as delivering greater durability and longer service life compared to the standard Neoprene and Nitrile compounds used by many other impeller brands, while JMP also offers Nitrile-specific versions for oil, fuel transfer, and food-sanitary applications where chemical compatibility requirements differ from seawater duty.

FAQ
Can this impeller be supplied as a JMP 810-01 replacement?
Yes, the product can be reviewed as a replacement reference for JMP 810-01 marine pump applications. However, the part number alone is not enough for production approval. Dimensions, blade profile, shaft connection, material 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 seawater, freshwater, coolant additives, oil exposure, temperature, rotation speed and dry-running risk. 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 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.
