Air Over Hydraulic Pump 3,200 PSI Double Action 122in³ Reservoir Foot Treadle Operated PA11-122D
Precision control meets dependable performance in the PowerX PA11-122D, a double-acting air over hydraulic pump engineered for industrial, construction, and maintenance applications that require smooth, balanced power in both directions. Rated for 3,200 PSI (220 bar), this 3-position, 4-way hydraulic pump delivers turbo-speed, high-flow performance with the strength and efficiency needed to operate double-acting cylinders and tools under demanding conditions.
The reinforced aluminum-alloy reservoir provides 122 in³ of usable oil capacity, supporting longer run times and consistent output through extended-duty cycles. Lightweight yet rugged, its corrosion-resistant construction ensures durability in harsh environments, while the one-piece air piston design minimizes air consumption and operating cost. A built-in pressure-relief valve adds overload protection for safe operation at maximum output.
Operating on 40–170 PSI of shop air, the PA11-122D foot pump starts easily even at low inlet pressures and runs quietly with minimal vibration. The anti-slip foot treadle provides hands-free control for precise operation, while the 3-position, 4-way valve allows smooth directional control of double-acting cylinders—making it an excellent choice for applications that require both extension and retraction power.
Compact, efficient, and engineered for productivity, the PA11-122D Air Over Hydraulic Pump is ideal for powering double-acting hydraulic cylinders, presses, pullers, and lifting tools in construction, mining, manufacturing, and heavy-equipment service environments that demand reliability and control.
Pair the PA11-122D with PowerX Double-Acting Cylinders or compatible hydraulic tools to build a complete 3,200 PSI system designed for balanced power, smooth performance, and maximum operating efficiency.
