2″ Diaphragm Pump

The Koshin KDP-50X diaphragm pump delivers 196 Litres per minute and 7.6M head.


Koshin’s line of self-priming diaphragm pump features positive displacement pressure for thicker than water viscosities. The quiet and reliable Honda GX120 overhead valve engine has a “low oil” sensor. The straight-line flow design is self-cleaning and eliminates clogging. The pump housing is made of lightweight cast aluminum while the standard wheel kit provides easy portability. Built to run dry without damage, it is perfect for areas of slow seepage. Oil-filled gear reduction means quiet operation.
