Schwing Pump Technology

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.
Pump Schematic

All 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 time.

This "boxer 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 for money.

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.
