On the basis of mature electric commutation technology,we have developed overall hydraulic concrete pumps with excellent performance. This hydraulic system deletes PCL, constent pressure pump, accumulator and approach switch four parts that are extremely damageable parts in electronic commutation system. It greatly improves the reliability of the machine and makes sure it can work in any hard condition. Our various motor concrete pumps( diesel engine concrete pumps) mainly cover capacity from 30-120m³/h and pressure from 5-20Mpa.



HBT and DHBT Series Concrete Pump Hydraulic system Advantages

Extend component life

overall hydraulic commutation system: the alternative commutation actions between pumping and S tube distribution doesn't involve electric signals. Little impact and noise occurs during the commutation, so the service lives of the hydraulic pump and valves are evidently lengthened.

Improve equipment reliability

Overall hydraulic system saves the intermediate process of the electric signals. In this way, the reliability of the whole equipment is greatly increased.

Reduce the failure rate

Full hydraulic commutation system adopts centralized valve plate, the hydraulic valves of main system are centralized in one valve plate. The number of cross-connected pipelines is reduced, the system gets more compact, at the same time the oil leaking possibility is decreased.

Reduce maintenance costs

Full hydraulic commutation system, deleting four parts extremely damageable in the electronic commutation system, reduces equipment maintenance costs.
