Piston Pumps (Golden)

The Golden Piston Pumps (GPP Series), commonly known as "Donkey Pumps" in Pakistan, are heavy-duty reciprocating positive-displacement double-acting water pumps designed for high-pressure water delivery applications. Unlike conventional centrifugal pumps, these piston pumps are engineered to handle greater vertical lifting requirements and long-distance water transfer with consistent performance. The series features a rugged mechanical construction with a cast iron main body, cylinder head, crank components, and piston assembly, combined with stainless steel cylinder liners and piston rods for enhanced wear resistance and durability. Its smooth-finish S.G. iron crankshaft, brass components, and abrasion-resistant rubber valves ensure reliable operation and extended service life. Designed for clean water applications, the pump provides strong suction capability, high-pressure head performance, and efficient water delivery through slow-speed, high-torque operation. Proper installation, including correct priming, accurate pulley alignment, suitable belt tension, and functional safety relief protection, is essential for achieving maximum efficiency and long-term reliability.
