For demanding construction and agricultural water removal applications where small abrasive material, stones and sand may cause premature wear on centrifugal pumps, Koshin offers 2″ and 3″ semi-trash units. Deeper cast steel impeller vanes coupled with a large volute discharge opening allow Koshin’s semi-trash pumps to pass water containing particulate matter and small solid objects without clogging the passage. These self-priming construction pumps feature a tough silicone-carbide mechanical seal and a quick clean-out port for easy maintenance and long service life.
The STH-50X is used New Zealand-wide by some of the largest construction and rental companies in the industry.
