Highland Hydraulic Motor Pump System notices:
Ensure that the hydraulic fluid you use has adequate thermal stability, especially in high-temperature environments. This stability prevents the formation of varnish and sludge, which can clog valves and lead to system inefficiencies. Use specialized thermal stability additives when necessary.
Highland Hydraulic Motor Pump System Use:
Mixer truck: concrete mixer truck, cement mixer truck;
Coal mining machinery: scraper;
Industry: pharmaceutical machinery;
Transport vehicles: road rollers, concrete pump trucks, stabilized soil mixers
