Pump: Innovative and reliable

With high delivery pressures of up to 130 bar for delivery outputs of up to 200 m³/h, Putzmeister pumps are  suitable for all concreting tasks. 

The S-transfer tube is the optimum leak-proof delivery system as there is only one point of separation between the spectacle plate and the transfer tube. The entire switch-over hydraulics and bearings lie outside the concreting area. The low number of parts and ease of exchange make them extremely  maintenance friendly.  Additionally, the hopper does not have to be dismounted to exchange the wear parts.

 

Durability

Specific details such as the durable delivery pistons, series standard chrome-plated delivery cylinders and the S-transfer tube system designed by Putzmeister ensure that all our machines are able to withstand long periods of intensive use.

 

Mode of operation

  • The low lying agitator which is driven at both ends shifts the concrete directly in front of the cylinder openings.
  • Two powerful and quick moving switch cylinders (which are muffled) move the trunk back and forth in front of the large suction openings, thus releasing the pressure and intake openings alternately.
  • Depending on the position of the S-valve the concrete is lighting into a cylinder or pressed through the delivery pipeline.

 

 

Piston Pump (S valve system)

Stationary concrete pumps with the S-transfer tube are continually setting new world records in vertical and horizontal delivery. For example, in 1994 at Riva del Garda in Italy, concrete was pumped vertically over 532m! Or a pump height of 606m at the Burj Khalifa job site in Dubai. Even in these cases, both the machines and accessories were not operating at their limits. Even when dealing with difficult concrete Putzmeister machines can be counted on to perform continiously and reliably.

Wherever extremely stiff and highly abrasive mixes are encountered this system is used. Of course it is also available with truck-mounted concrete pumps. In pre-cast factories you will find always find a piston pump when it comes to high strength concrete, steel fibre concrete or when there is a longer distance to cover.

The S-valve is the first choice for concrete pressures above 85 bars. This is especially useful for long pumping distances over stationary pipelines. The Putzmeister S-valve is especially designed for long life and high concrete pressure. This results in long service intervals and increased availability of the machine. To extend the life of the S-valve, the inside wall can be rebuilt by hard face welding.

Benefits at a glance

  • More power and less energy lost
  • High efficiency
  • While valves interrupt the oil flow on other systems, the intelligent control directs the oil into the drive cylinders without significant losses
  • Expensive control blocks are not required which avoids the oil heating up and makes servicing easier
  • Good ratio ensures powerful, convenient operation

Today concrete pumps are predominantly operated by hydraulic systems. Putzmeister places its trust in the benefits of free-flow hydraulics because the most important performance factors are the concrete pressure, low-loss oil delivery and costs.

When large quantities of concrete are pumped, large quantities of oil also flow inside the hydraulic system. More power is transferred inside a closed free-flow hydraulic circuit because the oil is conveyed from the pump to the drive cylinders without loss. The adapted hydraulic System ensures extremely powerful interaction between components because the oil Ratio is perfect. Compared to the open circuit, this ingenious drive technology requires significantly less oil and does not generate as much heat. The system is also economical to operate because it achieves a high degree of energy efficiency and is easy to service.

Ergonic

Greater efficiency, lower costs, increased flexibility – these are the results that Putzmeister truck mixer concrete pumps with Ergonic® systems can achieve in practice.

ESC is a system that ensures that the safety-related functions of the machine are monitored. It also allows you to work as flexibly and easily as possible within the framework of the existing directives and standards.

  • In addition to the possibility of full support, Putzmeister also offers a safe system for one-sided support.
  • Only certain arm positions and working areas are allowed in order to guarantee the stability of the concrete pumps in operation.
  • It is a win-win situation in terms of safety for people who work at and with the machine and for operators because the investment is protected against possible damage.

Base structure: Stability in the smallest space

The installation conditions on many construction sites are restricted because they are located in urban areas or alongside busy roads. Whether or not truck-mounted concrete pumps can be used essentially depends on the support dimensions. The OSS (One Side Support) and ESC (Ergonic® Setup Control) offer distinct advantages here:

  • Extent of supports significantly reduced with use of ESC and OSS
  • Flexible application options
  • Fewer obstacles in the surrounding area such as traffic
