KTH-LOGO.gif (8856 bytes)KC Series -  Magnetic Driven Centrifugal Pump
Polypropylene and PVDF
The Finish Thompson KC Series pump was introduced in 1990 and has become known for dependable service life and excellence in engineering design.  All KC Series pumps are seal less magnetic driven horizontal centrifugal pumps.  Pumps are constructed with polypropylene or carbon filled KynarŽ (PVDF)

Key features of the KC pumps is the usage of Neodymiun rare earth magnets.   They are compact in size and weight and strong in magnetic attraction.  Using smaller and lighter magnets provides pump designs allow; the usage of standard torque electric motors, lower weight impeller magnets requiring less support, and compact pump size designs.  All KC pumps are standard with high density carbon bushings and ceramic support shaft.  The usage of carbon allows the pump to run dry for up to 24 hours without damage to the pump.  For applications that carbon is not compatible, ceramic or PTFE bushing can be provided.  Four different size groups provide complete flow rate coverage from 5 GPM to 200 GPM.  For additional information see below.

All KC and DB Series pumps:

  • polypropylene or PVDF construction
  • high density carbon, ceramic  or TeflonŽ  impeller bushing
  • EPDM or VitonŽ  cover O-ring
  • ceramic shaft
 Solution Temperature Range
  • polypropylene - to 180o F
  • PVDF - to 220o F

* Actual motor horse power selection is determined by the specific gravity of the liquid.  Please advise us of actual liquid flow conditions and solution density for our recommendation.

Note:  Information for this pump using IEC motors and performance curves for 50 Hertz are available upon request.

Note:  Impeller bushing - Carbon bushing will allow the pump to run dry for short periods of time without damage caused by friction between the impeller bushing and the ceramic spindle.  Some chemicals such as chromic or bleach will attack carbon.  Abrasive solutions will cause wear of the carbon bushing.  Teflon and ceramic are options that could be considered -- however sever damage will occur to the pump if these bushing are used and the pump is run dry.

This pump is also available in a Vertical model - VKC Vertical Mag. Drive
