PUMI new generation – simply more flexible

At bauma 2016, Putzmeister presented the next generation of its tried and proven truck mixer concrete pumps: the PUMI 25-4 and the 28-4 New Generation. The most important advancements include the unique stepless support, the 4-arm distributing boom, the new S-pump, the Ergonic 2.0 control and technologies for reduced operating costs and exhaust and noise emissions.

In order to counteract wear, Putzmeister has further refined the design of its machines. The torsion-resistant integral frame and shape-optimised mixer drum ensure a consistent axle load distribution, preserving the machine over the long term and keeping operating costs low. The new PUMIs are proving to be eco-friendly and economic thanks to lower operating fluid consumption and reduced exhaust and noise emissions.
The stepless support allows a flexible and safe machine setup. The ESC (Ergonic® Setup Control), Putzmeister safety system, guarantees permanent control at all times through the interaction between support, boom movements and pump function. In addition to the full support, the machine can also be setup with one side support.
The 4-arm distributing boom with Z-fold offers optimised slip characteristics. The perfected kinematics enlarges the spatial working range and prevents “dead space”. This increases the effectively attainable operating reach. A 125 mm diameter delivery line supplies the required amount of concrete.
The PUMI 25-4 and the 28-4 New Generation are the first truck mixer concrete pumps to be fitted with the Ergonic® 2.0 control. An operating concept developed specifically for the machines makes operation of new PUMIs intuitive and hence very simple. The machine support is controlled by the Ergonic® Setup Control (ESC) safety system. The support ranges are displayed to the operator, thereby minimising operating errors.

Innovative design Made by Putzmeister
The latest generation models are recognisable even by their altered appearance. The shape-optimised mixer drum aids optimised axle load distribution. Additionally, the torsion-resistant integral frame ensures force is optimally transferred from boom to frame, from where it is conducted directly into the stabilisers. The incredibly stability and minimum movements during the pumping operation minimise wear and hence the associated costs.
The S-piston pump, designed specifically for the new PUMIs, is another innovative development. A large hopper, optimised accessibility to the water box and top performance data ensure a concrete pump that is ideally suited to the new PUMIs.
Lower exhaust and noise emissions, as well as reduced diesel and hydraulic oil consumption are easy on the budget and on the environment. This is made possible by a new drive concept and larger hydraulic pump. So the machine operates at a lower engine speed while the pump is operating. The new filter concept, which significantly reduces the number of oil changes, is also eco-friendly.
