Product advantages

Technical parameters

● ultra-high pressure, transmission over long distances, adjustment of displacement without restrictions

Maximum output pressure is 21 MPa, maximum transport length is 8 km. The volume of the hydraulic pump is adjusted using electronic proportional variable control technology, which allows remote stepless adjustment.


● stable output signal, small shock loads when changing polarity

Open hydraulic system, hydraulic system with multiple pumps and unified flow, with constant power management; The change of direction in the main hydraulic cylinder is carried out in a proportional manner with a sharp decrease in performance, which ensures small shock loads when changing direction and a low failure rate. Swing valve hydraulic cylinders use an adjustable set of damping valves, which reduces shock loads when changing direction in the swing valve hydraulic cylinders.


● High reliability key electrical and hydraulic components are made of imported materials; wear-resistant parts are made of special materials and designed in a special way, which ensures a long service life.


● High Inhalation Efficiency

The large inlet area S valve design increases the suction area and increases the suction efficiency.


● High efficiency and energy saving

The hydraulic pump volume is adjusted by electronic proportional change technology, ensuring accurate feed and high energy efficiency.


● Ease of maintenance

Repair and operation areas are easily accessible; open layout provides more space for maintenance; Special repair tools are provided in special places.


● Saving operating costs

Technology of automatic regulation of the feed volume, output as needed; high-quality hydraulic pumps and valve systems; durable wear parts (loading plates, cutting rings, pistons, S-shaped pipes, etc.), which ensures low operating and maintenance cost


● Built-in mixing device

A mixing device is installed in the pump fork, which improves the fluidity of the suspension and increases the suction efficiency of the pump. Hydraulic pumps and valve systems from leading world and domestic brands are used to ensure reliable quality; spare parts are made of special materials and using special technology (such as lenses, cutting rings, piston S-shaped tubes, etc.), which ensures a long service life of all equipment.
