Notices:

To maintain the optimal performance of your Heavy Duty Hydraulic Motors, it’s essential to regularly analyze the hydraulic fluid. Contaminants in the fluid can cause wear and tear, leading to decreased efficiency and potential motor failure. By conducting routine fluid analysis, you can detect and address contamination issues early, ensuring your hydraulic system operates smoothly. This practice is crucial in environments exposed to dust, debris, and other contaminants, such as construction sites and agricultural fields.

Application:

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
