Putzmeister’s iLS (intelligent low stroke) pumps are designed to ensure less wear through the use of larger cylinder diameters and fewer strokes.

Mirco Kuhlmey, product manager for truck-mounted concrete pumps, says: “This results in a significant increase in power due to a number of factors, including the prevention of leaks, improved suction performance and innovative control.”

According to Putzmeister, the seals on the hydraulic cylinders prevent oil leaks, increasing the efficiency of the core pump by a further 3%. The geometry of the delivery cylinder, S transfer and hopper are optimised to improve concrete flow while the Ergonic 2.0 control system saves up to 25% more fuel.

Additionally, the intelligent hydraulic pump control system helps to ensure the piston positions are recorded and evaluated during the entire stroke. The life of the components is extended as the stroke correction is no longer located in the end position.

The hopper lid can be positioned via the four spring-locked steps. The hopper grille sensor is located on the rear of the hopper and a simplified elbow replacement process uses the split screws.

The Ergonic 2.0 control system controls to engine, hydraulics and core pump to help reduce operating costs and save up to 25% more fuel.
