Finish Thompson KC11PCVN35 KC11 Magnetic Drive Wet end
Finish Thompson builds the KC11PCVN35 as a KC11 sealless magnetic drive wet end in glass fiber reinforced polypropylene. It is supplied as the wet end alone, the fluid handling section that carries the housing, impeller and barrier. There is no mechanical shaft seal anywhere in the design: the motor turns an outer magnet, and the field couples through a solid containment barrier to the magnet inside the impeller, so the only way out for the pumped fluid is the discharge port.
Removing the seal removes the usual failure mode. On a conventional pump the seal is what weeps, what needs flushing and what puts the pump back on the bench, and none of that applies here. The wetted parts are glass fiber reinforced polypropylene with a carbon bushing and a ceramic shaft, and the elastomers are Viton FKM. Maximum working pressure for this size is 35 psi, with the housing material setting the temperature ceiling at 180 degrees F.
Key Features
- Sealless magnetic drive with no shaft seal and no leak path
- Glass fiber reinforced polypropylene wetted construction
- Carbon bushing on a ceramic shaft
- Neodymium magnets for full torque in a compact coupling
- Back pull out design so the wet end is serviced without disturbing the piping
Applications
- Acid, caustic and solvent transfer where a leak cannot be tolerated
- Plating, etching, anodizing and metal finishing lines
- Water treatment, scrubber and filtration recirculation
- Laboratory, photo processing and chemical blending systems
- Replacing a sealed pump that keeps failing at the shaft seal

Frequently Asked Questions
Q: Is a suction strainer worth fitting?
On a magnetic drive pump, yes. The running clearances are small and a single piece of debris can take out the bushing.
Q: How is the pump taken apart for service?
The wet end separates from the motor adapter without disturbing the piping, so bushings and O-rings can be renewed in place.
Q: What causes most premature wet end wear?
Dry running, abrasive solids, and operating well to the left of the curve where recirculation heats the fluid inside the pump.
Q: Does a higher specific gravity fluid need a different pump?
It needs more torque, which is why the heavier duty builds use a stronger magnet coupling rather than a bigger motor alone.
