Burks 20158-6 Turbine Repair Kit for CT6M series
The Burks 20158-6 is the genuine Burks turbine pump repair kit for all Burks CT6M series pumps. It gathers every wearing part in the wet end into one box: impeller, raceway, shaft seal, O-ring gasket, impeller locknut and instructions. Buying it as a kit is what keeps a rebuild to a single afternoon instead of three separate orders.
The classic symptom is a pump that still turns, still moves liquid and no longer makes pressure. In a regenerative turbine that almost always means the clearance between impeller and raceway has opened up. Replacing one part without the other leaves a worn surface running against a new one, and the pressure never fully comes back.
This kit is built around the standard Buna-N seal specification. Pumps ordered with Viton, EPDM or a high-temperature seal arrangement take a different kit, so check the nameplate and the original order before fitting. Confirm the pump is one of the CT6M series models as well, because the impeller and raceway are sized to the model.

Frequently Asked Questions
Q: How often should these pumps be overhauled?
It depends far more on the liquid than on the hours. Clean water and a flooded suction can run for years, while anything carrying grit shortens the interval sharply. Trending discharge pressure at a fixed flow is the most reliable way to plan the work.
Q: Will this kit change the pump performance?
It restores it rather than changing it. The kit brings the internal clearances back to factory dimensions, which is what returns the pump to its original pressure and flow curve.
Q: Do I need any special tools to fit this kit?
Nothing exotic. A means of holding the impeller while the locknut is released, a puller for a stubborn impeller, and a torque wrench for reassembly cover most jobs. The instructions in the box give the sequence and the settings.
Q: Can I fit just the impeller and leave the raceway?
It is a false economy. The two wear as a pair and the clearance between them is what makes the pressure, so a new impeller inside a worn raceway gives back only part of the lost performance and the job has to be done again sooner.
