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, results in low energy
consumption at different pumping conditions. Additionally
the concrete flow can be manually adjusted and the pump
operates in a proven open circuit.
The pump is renowned for it's low fuel consumption.
Automatic adjustment by the governor helps maintain a
constant output depending on the power available from the
installed drive motor.
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
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 bars and pneumatic tyres for travelling on construction sites at upto 25 km/hr.
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 aintenance. Both gate valves change independently so that even when full change over is prevented
by foreign materials or similar bstructions in the concrete, the pump continues to operate without problems. All
components are specially developed and manufactured to withstand the rough conditions on construction sites.
Hopper and Agitator
Good suction power is possible due to large apertures at the hopper bottom section. According to the conditions on
the construction site the hopper equipped with a grill and rubber border standard can be provided with an appropriate
extension as an option. The agitator is driven by separate hydraulic pump. The reversible agitator motor drives the
agitator shaft via an oil bath gear box.
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.
Ideal flow conditions in the control housing results in superior
placing properties, even in the case of concrete low on sand and
fines, stiff consistence or crushed aggregates. Simple tilting of the
output pipes enables easy control and cleaning of the concrete
conveying path and the gate valve parts.
Pumpable concrete, within any consistency range down to a water
cement ratio of 0.4. Even concrete with aggregate grading up to
40mm can be pumped by with the concrete pump through a
125mm diameter pipe line.
Flat gate valve
The two flat gate valves working independently have been specially
developed for pumping concrete. Their working system with
automatic adjustment permits trouble free pumping even with
badly worn parts.
Integrated Control Block
The hydraulic control system is integrated within the drive. The
compact control block & minimal hydraulic lines makes the
equipment reliable & durable.
