OTC 4020 Air/Hydraulic Foot Pump

The OTC 4020 is an Air/Hydraulic Foot Pump. With shop air as the energy source, the pump has the power and oil capacity (80 cu-inch usable oil) to drive even the large 55 ton rams. It is an ideal all-around power source for dozens of body, frame and alignment applications. It can be used with a variety of rams, presses and hydraulic pullers operating at up to 10000 PSI. An internal relief valve protects the hydraulic components regardless of hydraulic pressure. In addition, a two-stage release mechanism gives fast or metered ram return while reducing hydraulic shock.
