Concrete Trailer Pumps

The motor (Diesel or Electric) drives the axial piston pump via a flexible coupling. Due to automatic output adjustment optimum utilization of the motor power, resulting in low energy consumption at differing   pumping condition. Additionally, the concrete flow can be manually adjusted. The pump operates in a proven open circuit.
The maximum   placing output   and the pressure   are determined by the construction sites. Between these two values, automatic adjustment  by the governor occurs maintaining a  constant output depending on the  power available from the installed drive motor.

Design

The portable concrete pumps are assembled in the unit construction system.  The main assembly groups are Frame, Power unit, Concrete pump kit, Control block, Hydraulic tank and Hopper with agitator.

The Frame & Axle 

The frame, in compact execution, is constructed from standard vehicle profiles. The pump is mounted on heavy duty single axle chassis with draw bar, pneumatic tyres and for travelling on construction sites at up to 25 km/hr.

Control System 

The fully hydraulic control system is integrated within the drive. The compact control block and minimal hydraulic lines makes the equipment reliable and durable. The differential cylinder has trouble free piston rings and automatic constant stroke maintenance. Both gate valves change independently so that even when full change over is prevented by foreign material or similar obstructions  in the concrete, the pump continues to operate without problems. All components are especially developed and manufactured to withstand the rough treatment on construction sites.
