Description:

Drive
The motor (diesel or electric) drives the axial piston pumpvia a flexible coupling. Due to automatic outputadjustment optimum utilization of the motor power,results in low energy consumption at different pumpingconditions. Additionally the concrete flow can bemanually adjusted and the pump operates in a provenopen circuit.The pump is renowned for it's low fuel consumption.Automatic adjustment by the governor helps to maintain aconstant output depending on the power available fromthe 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 heavyduty single axle chassis with draw bars and pneumatic tyres for travelling on construction sites at upto 25 km/hr.

Control System
The fully hydraulic control system is integrated within the drive. The compact control block and minimalhydraulic lines makes the equipment reliable and durable. The differential cylinder has trouble free piston ringsand automatic constant stroke maintenance. Both gate valves change independently so that even when fullchange over is prevented by foreign materials or similar obstructions in the concrete, the pump continues tooperate without any problems. All components are specially developed and manufactured to withstand therough conditions on construction sites.

Hopper and Agitator
Good suction power is possible due to large apertures at the hopper bottom section. According to the conditionson the construction site the hopper equipped with a grill and rubber border standard can be provided with anappropriate extension as an option. The agitator is driven by separate hydraulic pump. The reversible agitatormotor drives the agitator shaft via an oil bath gear box.

Pumping Cylinders
The two pumping cylinders are hardened by a special process and designed for an extremely long working life.The replaceable hard rubber arms are easily changed due to quickly detachable connections.

Control Housing
Ideal flow conditions in the control housing results insuperior placing properties, even in the case ofconcrete low on sand and fines, stiff consistence orcrushed aggregates. Simple tilting of the output pipesenables easy control and cleaning of the concreteconveying path and the gate valve parts.

Flat Gate Valve
The two flat gate valves working independently havebeen specially developed for pumping concrete.Their working system with automatic adjustmentpermits trouble free pumping even with badly wornparts.Pumping MaterialPumpable concrete, within any consistency rangedown to a water cement ratio of 0.4. Even concretewith aggregate grading up to 40mm can be pumpedby with the concrete pump through a 125mmdiameter pipe line.

Integrated Control Block
The hydraulic control system is integrated within thedrive. The compact control block & minimalhydraulic lines makes the equipment reliable &durable.
