Koshin Pump Parts 

Repair your Koshin brand water pump, Honda engine drive or electric submersible pumps. PumpBiz has the parts in stock and ready to ship to any state in USA, Candada, Mexico and the rest of the World. Overnight shipping is available.

Need help with fixing your Koshin pump, contact PumpBiz for FREE expert help, tip, tricks and tools. Need a manual? Simply look up your pump and find the repair / parts manual on the pump page under the "Docs" tab.

Also repair many other brands with Koshin OEM parts, subaru, powermate, godwin, wacker. Many generic / off brand pumps "look" like the brand name pumps above, but since they were cheap china pumps the parts are not identical. Further, the engine or motor brand has nothing to due with the pump mounted to it as far as identification. Honda engines are used on the quality pumps like Koshin, AMT and Pacer but they are also used on the cheap clones.
