□ It is driven by diesel engine. The main pumping system is equipped with open loop, constant control, pressure cut protection. It also can realize the infinitely variable speed of the master hydraulic cylinder and adjust the concrete output.

□ All hydraulic pumps and main valves are original German Rexroth products.

□ The high and low pressure conversion of the outlet pressure can achieve large discharge at low pressure and small discharge at high pressure so different conveying distance and height can be realized.

□ Powerful and low-noise Deutz diesel engine.

□ The reversing control is electric-hydraulic type. The electric part is controlled by PLC, which is reliable, more accurate with small impact.

□ The counterforce on specially designed “S” valve is received by hopper wall to assure the service life of goggle plate and cutting ring.

□ Control mode: manual operation and wireless remote control.

□ Reverse pumping function can facilitate cleaning the conveying pipe.

□ Unique mixing unit can achieve homogeneous mixing of different proportioned concrete so as to realize ideal pumping effect.

□ Automatic lubricant filling device can eliminate the trouble of manual filling and extend the service life of the parts with less abrasion in the lubricants.
