Profile: PSS Technologies specializes in the design and supply of fully automated, high pressure emulsion pump systems for provision of hydraulic fluid power to critical roof supports in coal mining applications. Our high flow, low pressure water systems provide the perfect solution to reduce air-borne coal dust by supplying clear spray water to the shearer, the coal plow and to drive motor cooling systems. Our directional control valves are suitable for water and oil hydraulics control systems with working pressures up to 320 Bar. They are characterized by fast response times and seal using a ball seat valve.
