Omega Portable Foot Pump with an air-actuated/manually-operated design and usable oil capacity of 91.5 cubic inches provides up to 10,000 PSI with a standard shop air supply of 90-175 PSI. Omega Air Hydraulic Treadle Pumps supply compressed hydraulic fluid to compatible applications, such as rams, presses, and compactors, where 10,000 PSI (700 Bar) of fluid pressure is needed. Made of durable, lightweight, and corrosion-free aluminum, this portable, heavy-duty unit allows you to efficiently operate any single-acting rams (up to 55-ton capacity) in many industrial and construction applications, and the built-in pressure by-pass system protects overload operation. The user-friendly, foot-actuated design allows for easy control of fluids moving at tremendous rates, using a 3/8" NPT fluid coupler, and a 91.5 cubic inch reservoir is included.
