"Handles a wide variety of industrial applications. All models have 1725 RPM TEFC totally enclosed, fan-cooled motors, check valve, adjustable relief valve and 3000 PSI pressure gauge. High strength cast iron housing. DU bearings. Filler screen, sight gauge and flexible coupling. Hardened and ground alloy steel gears and shafts. Pressure-balanced pumps provide up to 90 overall efficiency. Ideal for systems using low viscosity fluids in high temps and high duty cycle applications. Pressure balanced pump provides high speed positioning and then maximum working pressure as in clamping, crimping and metal-forming machines. Does not include manifold or interface. HP 5, Inlet Port in. 9/16 18 SAE, Outlet Port in. 9/16 18 SAE, Phase 3, Reservoir Capacity 15 gal., Volts 230, 460 AC, Flow GPM 3 1/2 GPM @ 2,150 PSI. Fully integrated power unit, featuring reservoir, electric motor and pump Robust construction featuring steel reservoir Built-in check valve and relief valve for protection against over-pressurization of system components Includes filter and breather to ensure fluid cleanliness TEFC motor for extended duty cycles Pressure balanced pump for high efficiency operation which maximizes flow rate AC motor for use in industrial application such as garage door lifts, hydraulic presses and lift tables Pressure gauge monitors system's operating pressure up to 3000 psi Reservoir drain plug allows for easy fluid replacement"
