JBL CPe1501 Impeller + Shaft + Bearing

JBL CPe1501 Impeller + Shaft + Bearing is the pump service kit for the JBL CristalProfi e1501: impeller, shaft and bearing together. These are the only moving parts in an external filter, and they are what wears out long before the filter body does.

Key Features

• Impeller, shaft and bearing: the complete set of wearing parts, so nothing is left old running against new.
• For the JBL CristalProfi e1501: match the model number on your filter before ordering.
• Replace them as a set: a new impeller on a worn bearing will not last. Changing all three together is what restores the pump.
• Fixes a rattle or weak flow: the two symptoms of a worn pump, and the two that get blamed on the whole filter.
• No tools needed beyond the filter head: the head lifts off and the parts come out.
• Cheaper than a filter: a service kit will bring a tired external filter back rather than replacing it.

Fitting It

• Switch the filter off at the mains and isolate the hoses before you open anything, with a bucket and towel underneath.
• Lift the pump head off and note how the old parts sit before you take them out. The shaft and bearings only go back one way.
• Clean the impeller chamber while it is open. Grit and limescale in the chamber are what wear the next impeller out.
• Seat the new impeller without forcing it, refit the head and check the seal before you switch on.
• Prime the filter and listen. A rattle means something is not seated.

Good To Know

• A noisy or weak external filter is usually the impeller, the shaft or the bearings rather than the pump. They are the only moving parts in it.
• Replacing the impeller, shaft and bearings together gives the best result. A new impeller running on a worn bearing wears out quickly.
• Never run an external filter dry, even briefly. That is what kills impellers.
• Check the model number on your filter against this part before ordering. JBL has made several generations of the CristalProfi e and the pump parts are not interchangeable between them.
• Keep the old parts if they still turn. A spare impeller in the cupboard is worth having the day a filter starts rattling.
