Fine stone concrete pumps

Configuration

Hydraulic system

The new hydraulic commutation control technology makes the pump word more reliable and has a lower failure rate of hydraulic system. It is equipped with specially-made valves with large flows, little energy consumption and light impact, ensuring longer service lives.

Power system

Electromotor adopts famous brands at home and abroad, Yantai Motor and Beide Motor of Siemes. Diesel engine adopts Tianjin LOVOL and Yuchai Brand with low energy consumption and high efficiency.

Mail oil pump

Main oil pump adopts joint venture brand constant power variable plunger pump. Constant power control is effective to prevent the electromotor or diesel engine form overloading. It can withstand higher pressure and load than conventional gear pump.

Cooling system

It adopts dual-cooling system, with cooling and water cooling, not only for hot climate but also for cold climate, it can effectively control the oil temperature of hydraulic system and ensure the safety and reliability.

Electric system

Main electric elements are Schneider and LS brand

Hopper Device

The hopper is capacity-increased, coupled with fence and equipped with vibration motor to meet the requirements of fine aggregate concrete pumping.

S tube

S tube valve is casted into form with ligh manganese steel. The easy-worn surface if welded with anti-wear material, which is anti-high pressure and anti-wearing. The inner surface of the tube transits smoothly and concrete can flow freely in the tube, further improving the pumping performance. The splined shaft is made of alloy and the surface is specially treated, enhancing the performance of anti-wearing and anti-fatigue.

Glassed plate

Glasses plate and cut loop are made of hard alloy and have long service lives.

Hydraulic pipes joints

American Eaton; Pipeline: Original from Italy supported by Etaon

Centralized lubrication system

The lubricant will be injected to the main oil line by the plunger pump and distributed to each lubrication point by the distributor. Point-to-point lubrication protects main components from wear and tear.
