Honda High Pressure Pumps WH15XK1C1 and WH20XK1AC1

Updated Jul 29, 2010

High Pressure

Honda’s high pressure pumps are designed for moving clean, uncontaminated water – excluding drinking water or flammable liquids – from one place to another.  Typical applications for the general purpose pump series include irrigation, flood control, light construction, fire fighting and swimming pool drainage.  Thanks to the use of Honda’s quiet four-stroke engines and superior technology, these pumps boast incredibly low decibel levels.

The WH15 and WH20 model pumps offer high pressure with a lower flow.  The best application for these water pumps is where higher pressure is required, such as a sprinkler, irrigation systems or use with hoses and nozzles.
