Jabsco # 8600-0023B Impeller

Applications:

The Jabsco 8600-0023B is a replacement impeller used in Industrial processing applications. After replacing and installing the new impeller, the pump will need up to 30 seconds to prime - DO NOT run dry any longer than 30 seconds as the lack of liquid will damage the impeller. Ensure suction pipework is airtight or the pump will not self-prime.

Impeller Replacement:

Replacing impellers is easy. By removing the end cover screws, it is possible to remove the impeller by using either a Jabsco Impeller Removal Tool, or channel lock pliers, to grip the hub of the impeller. Don't use screwdrivers as they may damage the face of the pump body, causing leaks, and they can be dangerous in confined spaces.
The Flexible Impeller Removal Tool is the easiest way to remove impellers, especially when the pump is mounted in tight and cramped conditions. The Flexible Impeller Removal Tool easily removes the impeller, and removes the risk of expensive damage to the pump.

Always grease new impellers. Firstly, it makes it easier to install the impeller into the pump bore, and secondly it gives added protection to the impeller during initial prime. After replacing the gasket and end cover the pump is ready to use.

Troubleshooting:

This is a replacement impeller.
Depending on how often you use the pump and how hard you are on the impeller you may need to replace this once every few years, or a few times per year.
The normal end of the flexible impeller is when there are some pieces of a blade or blades missing, and/ or some of the impeller blades are permanently and excessively curved. The blades might also be cracked about half way up their height. Sometimes the impellers can wear out because of system issues like cavitation or air being sucked into the system, and you might see pieces missing from blades tips especially in center of impeller.
Note that Flexible Impeller pumps need up to 30 seconds to prime - but do not run dry any longer as lack of liquid will damage the impeller.
If the system does not have liquid in it while the impeller is running for even a minute the impeller can burn out. If this is the case you will see that the impeller end faces are hard, polished, and cracked, like carbon. You may be missing some or all of the blades completely in severe cases. Do not run your impellers dry / without liquid. |
