For sale is a used Hypro Model D50 semi-hydraulic diaphragm pump. This is a heavy-duty commercial unit rated for 14 GPM at 580 PSI, making it the perfect workhorse for agricultural spraying, weed/pest control rigs, or liquid fertilizer application.

Comes complete with the integrated gear reduction drive kit designed to mount directly onto standard 5 HP to 6.5 HP small gas engines (like a Honda GX160). It includes the top pulsation dampener, pressure gauge setup, and control valve assembly.

Sold as-is. Great replacement unit or core for a custom skid sprayer build.
