Air Over Hydraulic Pump 3,200 PSI Single Action 231in³ Reservoir Foot Treadle Operated PA11-231
High efficiency meets high capacity in the PowerX PA11-231, a single-acting air over 2P/3W hydraulic pump engineered for industrial, construction, and maintenance applications that require reliable performance. Rated for 3,200 PSI (220 bar), this air-driven hydraulic pump delivers turbo-speed output with high flow at high pressure, outperforming competitors in both speed and durability.
The reinforced aluminum-alloy reservoir provides a generous 231 in³ of usable oil capacity, allowing extended run time between refills while maintaining consistent flow during long-cycle operations. The corrosion-resistant body keeps weight low without sacrificing strength, and the rugged one-piece air piston minimizes air consumption and operating costs. A built-in pressure-relief valve adds overload protection for safer operation under demanding conditions.
Operating on 40 – 170 PSI of shop air, the PA11-231 starts easily even at low air pressure and runs quietly with minimal vibration. The anti-slip foot treadle offers precise, hands-free control for added safety and efficiency in workshop and field environments.
Compact, efficient, and built to last, the PA11-231 Air Over Hydraulic Pump is ideal for powering single-acting hydraulic cylinders, presses, pullers, and tools used in manufacturing, construction, mining, and heavy-equipment maintenance.
Pair the PA11-231 with PowerX Automotive Cylinders, Flat Body Cylinders, Low Profile Cylinders and select Center Hole Cylinders to build a complete 3,200 PSI hydraulic system that delivers dependable performance, long cycle life, and superior control.
