Features
- Significant energy reduction: Lower motor power compared with conventional slurry pumps results in 50%–80% lower energy consumption and reduced operating costs.
- Higher pressure and efficiency: Delivers higher outlet pressure (up to 2 MPa) than traditional slurry and screw pumps, improving filtration efficiency and reducing moisture content.
- Vertical structural design: Minimizes wear caused by abrasive particles in the slurry, significantly extending the service life of cylinders and seals.
- Excellent wear and corrosion resistance: Engineered for industries where both abrasion and chemical corrosion are common.
- Low noise and vibration: Operates smoothly without damaging flocculated slurry states.
- Smart lubrication system: Provides timed, closed-loop lubrication for seal groups to prevent hydraulic oil loss and contamination while avoiding human-error-related seal damage.
- High feed pressure: Ensures stable and reliable high-pressure feeding.
- LED status indicators: Allows operators to easily monitor real-time operating conditions; instructions are processed and issued through the PLC.
