Weatherford‘s 37kW-EHPU is designed for temporary installation in outdoor areas to ensure safe operations in explosive areas that meet ATEX regulations. This piston-pump (variable displacement) designed system is used in open- or closed-center hydraulic circuits, with the pump directly connected to the pressure control valve. Working pressure can be regulated by the hand-wheel pressure relief valve. The EHPU’s flow-setting valve regulates the maximum hydraulic system flow required by the connected equipment. An integrated air cooler controls the temperature of the hydraulic fluid. The power unit is frame-mounted, with a hose basket to carry hydraulic hoses and other equipment when not in use.
