Primary Mover Gasoline Hydraulic Pump – Multiple Start, Reservoir, and Valve Options | PF-GPU Series

Primary Mover 200cc Gas-Powered Hydraulic Power Unit Built to Perform Under Load — Not Just on Paper Most gas-powered hydraulic units look impressive at no load, but once pressure increases, performance drops off fast. That’s where cycle times slow down and frustration begins. The Primary Mover 200cc Gas Power Unit was designed to solve that exact problem. After years of selling and supporting traditional 160cc gas units sourced from vendors, we engineered our own system from the ground up — optimized to maintain usable hydraulic flow at real working pressure. The result is a power unit that stays fast where cheaper units fall off — especially near 3200 PSI, where heavy dump trailers and truck beds actually operate. Why Flow at High Pressure Matters Many gas power units advertise high flow numbers, but those ratings are typically measured at very low pressure. In real dump trailer applications, pressure rises quickly, and flow is what determines how fast your bed actually lifts. The
