Based on our mature hydraulic large concrete pumps especially for urban construction and the new rural reconstruction, our company developed the mini model that could pump not only large aggregate concrete but also fine stone concrete and mortar. We mainly manufacture this mini concrete pumps with capacity 20-50m³/h and delivery pressure 7-13Mpa. This mini concrete pump is widely applied in the construction, transportation construction, railway construction, hydraulic and power engineering, etc. Main oil pump adopts Kawasaki series from Japan.



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.
