AplO DeZURIK HPU-DHS HYDRASTORM HYDRAULIC POWER UNIT Design and Construction DeZURIK's HydraStorm Hydraulic Power Unit (HPU-DHS) generates a tremendous amount of power to drive most valves fitted with hydraulic cylinder actuators. The HPU-DHS is designed specifically with rugged construction and diverse capabilities to best suit the needs of tough indoor/ outdoor industrial applications in numerous industries including mining, power, hydropower, water, wastewater, and others. HPU-DHS Hydraulic Power Units are available in a variety of AC and DC voltages, three reservoir sizes, flow rates up to 24 gpm (90 l/min), pressures up to 3000 psi (20,684 kPa), and an operating temperature range from -49 to 140°F (-45 to 60°C). The HPU-DHS system is compact, portable, quiet and fully enclosed with IP66 protection (dust tight, water jet protected). Offered with intuitive operator controls and capable of operating a number of valve actuators, the HPU-DHS is both user friendly and easy to maintain. Application The HPU-DHS is used in applications that would encounter power failures and extreme environmental conditions, where higher speeds & controlled valve actuation is critical. Due to their high power density, & lower power usage, hydraulics are often the chosen method for valve actuation in challenging applications. Base Frame HPU-DHS Hydraulic Power Units enclosure includes an ergonomically designed base frame positions the control panel at a 48” operator height. The operator interface, with large buttons and switches, allow for gloved operation. Lifting eyes are incorporated into the frame for easy lifting and footpads on the legs are pre-drilled to allow the unit to be secured to a surface. The entire structure and reservoir are coated for protection. Operation and Maintenance Controls for Valve Open, Valve Close, Light On/ Off, and Heat Cycle On/Off are included on the face of the control panel. Temperature of the oil and ambient air temperature are monitored, and help with the heat cycle for efficient operation. The warning indicator lamp blinks to indicate; Dirty Filter, High Temperature, and Service Interval. Area

lighting is provided by two durable frame mounted LED's. Power connection is standardized. Main power disconnect is lockable. The entire assembly is designed for ease of maintenance. The unit is easily disassembled for cleaning and maintenance. All key components are accessible and replaceable. Controls Variable Pressure & Speed Control The variable pressure and speed controls allow the user to adjust force control and valve speed of operation. For example, if the cylinder requires 1700 psi to operate, the user simply sets the pressure control to 1800 psi (100 psi above the required pressure...
