  • The clean-out cover and volute can be easily removed in seconds for easy cleaning of debris.
  • Suction lift to 26FT.
  •  The seal is the heart of the pump. Silicon Carbide seals, developed exclusively for Koshin, vastly increase the durability of the mechanical seal and protect engine shaft. Silicon carbide SiC seals are 2 times harder, 15% tougher, and 50% stronger than common ceramic seals.
  • Impeller is Hi-chrome cast iron. Volute manufactured from Spheroidal Graphite (ductile) cast iron. These materials employed to ensure long life, erosion resistance  and low maintenance. No wear plates to wear out as on the imitations.
  •  Sturdy steel wrap-around pipe frame protects entire unit.
  • Rubber mountings minimize vibration.
  • Koshin OHV engine with oil alert, cast iron cylinder and electronic ignition provides reliability and low fuel consumption.
  • All aluminum die cast pump housing for light weight and portability.
  • 0.95 Gal. fuel tank provides up to 2 Hrs run time.
  • Commercial 3-year warranty on engine and pump ends.

 Do not be fooled by imitation "industrial" pumps sold elsewhere. The pump quality is not the same and as with any pump parts will be needed and PumpBiz stocks parts to all the pumps we sell and support. These are the same pumps used by many rental stores, so they have proven themselves many times over.

Cast Iron impeller and volute are premium Spheroidal Graphite Cast Iron. This provides much greater wear resistance than ordinary and less expensive plain cast iron. Koshin is the ONLY pump manufacturer to use this high grade material. Other 2" trash pumps
