Whatever result you want to bring about … Power and pipeline – A first-class combination Over the years and decades, our concrete pumps have become increasingly more powerful. This is an achievement that makes us proud, and which ultimately serves to achieve your objectives faster and more effectively. There are high demands which you can place on our pumps and which should be just as decisive when selecting the delivery lines. This applies as much for the pipework in the boom as it does for stationary delivery lines. With the SK and ZX series, or the PX hose system, we are offering, in combination...

Flying high – The pipework in the boom Delivery lines need to meet many diverse demands resulting from their particular use, the medium to be conveyed and the connected pump. For example, the pipework on the placing boom of truck-mounted concrete pumps is required to be flexible and movable. However, the components must be extremely robust and must have a long service life in order to keep the operating costs low and to maintain the level of availability of the machine. Suitable for handling long distances – Stationary delivery lines The task of stationary delivery lines is to transport the widest...

Congestion-free feeder for all demands Outstanding properties in all parts Increasingly more pressure, increasingly more output – the further development of the pumps has also had a decisive influence on the properties of delivery lines. They must remain leak-proof at extremely high pressures and withstand higher flow rates over as long a time period as possible. However, the greater the volumetric flow rate, the higher the level of stress and wear. The delivery line systems from Putzmeister therefore have various re- sources to counter this. Extremely robust pipes, for example, are available...

A system is only perfect when it is complete Delivery lines with matching coupling systems create a connection that is one hundred percent secure. They are adjusted to the purpose and, depending on this, are extremely mobile, easy to assemble, quick to open or extremely rigid. Reducers, transition pieces, delivery and end hoses, a wide range of cleaning accessories and measuring instruments are available to provide an integrated system solution. Our systems provide you with the best manually and hydraulically operated gate valves and transfer tubes, which can be operated via external hydraulic...

The SK delivery line system – The ideal combination of robustness and adaptability SK system – Absolutely robust, no matter how you twist and turn it The SK quick-release coupling system is ideal if pipelines must be installed flexibly and quickly, and concrete pressures are up to 85 bar*. They can also be rotated axially and can be bent by up to 2° so that they can be optimally adapted to the conditions at the construction site. Due to these preferences, the SK system comes as standard equipment on Putzmeister truck-mounted concrete pumps, but is also very well suited for shorter, fixed pumping...

SK two-layer pipes When it comes to costs per m3 of pumped medium, it may be more economical for highly abrasive materials and high outputs to invest more in the delivery line. For a longer life, Putzmeister therefore offers two-layer pipes. These consist of a hardened, especially wear-resistant inner pipe and a soft outer cladding and protective pipe. Standard two-layer pipe: This pipe has an internal hardness of 63 HRC Rockwell (corresponding to approx. 780 Vickers). For delivery lines on the placing boom, the inner pipe is 2 mm (PM 22) or 2.5 mm (PM 252) thick, while the outer pipe is 2 mm...

SK-H lever coupling as mounting coupling Couplings All SK couplings from Putzmeister are drop-forged and are electrogalvanized as standard, this guarantees a long life and reliable use. A securing cotter pin on the lever couplings prevents the coupling from being opened unintentionally when under pressure. You can choose between three different models: S K-H lever coupling as a flexibly mounted coupling or as a mounting coupling; for extremely fast, uncomplicated manual opening without the need for additional tools S K-S threaded coupling as a secured connection for delivery lines S K-K handle...

ZX Zentrifix® – Robust connection which is absolutely leak-proof ZX Zentrifix® system – Extremely resilient at high pressures and with heavy materials Pumping under high pressure – this is where particularly high demands are placed on the delivery line. They must be absolutely leak-proof, stable and wear-resistant. The ZX delivery line system from Putzmeister fulfils these criteria with ease, and is therefore ideal for fixed, stationary pipe systems in concrete high-rise and long-distance placement. However, beyond construction sites, the system is tried and tested in a wide variety of industrial...
