Schwing concrete pumps set the standard for modern concrete conveying.
With worldwide experience and up-to-date technology Schwing engineers
have designed highly efficient and low-wearing pumps ideal for long-term
use under the most severe conditions. These concrete pumps (and
sludge pumps) are hydraulically driven, twin-cylinder pumps. Their
hydraulic drive and control systems (called the "brain")
have all been designed by SCHWING engineers specifically for applications
in concrete and sludge pumps. Because of this, they fulfil more than
just the necessary functions of a hydraulic pumping system. The combination
of the two systems achieves an extremely steady and gentle pumping
pattern, even at maximum outputs.
Schwing concrete pumps are designed and built with an open hydraulic
circuit. With lower maintenance and operational costs Schwing
pumps provide efficiency even in the most severe working conditions.
Hydraulic oil is
pumped under pressure to the working cylinders. The hydraulic
brain block runs through a compulsory control sequence and extends
one of the working cylinders, the other retracting at the same
stroke" is transferred to the concrete pumping cylinders
so that one cylinder pump draws in concrete and the other one
pumps concrete into the connected pipeline.
The Rock Valve
The heart of the concrete pump, the Schwing Rock valve is
recognised all over the world for its high performance and
economy in the most difficult situations and locations.
The Rock is robust and easy to service. It is subject to
natural wear when pumping concrete and can then be rebuilt
with hard-face welding. That makes it multi-economical. A
real example of foresighted engineering, flexibility and value
The standard Rock offers efficiency and economy; the extended
G-Rock is suitable for dificult, stiff concrete mixes while
the extended and widened E-Rock ideally complements the long
stroke battery 2525 H with 250mm concrete cylinders.
