Model Comparison: 17936 Versions at a Glance
-
17936-0001B (this article): The pure single impeller (bulk) without any accessories.
-
17936-0001-P: The complete service kit including lubricant and the most common body gasket for a professional impeller replacement.
Note on Impeller Markings: Original Jabsco impellers often have the internal production number 17936-0001 or 17936-0101 molded directly into the rubber. These represent the identical component, and the single impeller 17936-0001B provides the exact matching replacement.
The Advantages of Jabsco Original Quality
-
Specific Rubber Compound: Guarantees precise elasticity and dimensional stability even at extreme fluid temperatures.
-
Constant Flow Rate: Reliably stable volume flow over many operating hours.
-
Vulcanized Core: The high-strength vulcanization bond between the robust brass hub and the neoprene body prevents the elastomer from detaching under load. The maximum drive torque is fully maintained, and spinning on the shaft is effectively minimized.
-
Excellent Memory Effect: The blades straighten up precisely millions of times, ensuring fast and powerful self-priming.
-
Dimensional Accuracy: Tight manufacturing tolerances ensure an optimal fit in the pump housing and maximize efficiency.
Maintenance, Storage & Service Life
-
Replacement Interval: As a central wear part of the raw water cooling system, the impeller should be replaced annually as a precaution. A failure can lead to overheating and severe engine damage. Commercial or intensively used systems may require shorter maintenance intervals.
-
Dry Run Protection: Always use a suitable glycerin-based impeller lubricant during installation to prevent friction damage (scorch marks) during the first startup.
-
Storage: Store in a cool, dark, and dry place. Maximum shelf life before initial commissioning: 5 years.
Practical Tip: Always carry at least one spare impeller in your inventory or on board for critical systems. Use an impeller puller for removal to avoid damaging the bronze pump housing.
