Heidelberger Druck optimises cooling lubricant pumps
21 Sep 2017

Heidelberger Druckmaschinen AG is a global provider of products and services for advertising and packaging
printing. The company’s offerings focus mainly on sheet-fed offset and digital printing solutions and on the
manufacture of components and assemblies for the precision engineering sector.

At its production site in Brandenburg an der Havel, Heidelberger  manufactures shafts, cylinders, sections and prefabricated assemblies. There, Heidelberger decided to replace the existing pump sets and modernise the control system.  Thanks to the performance of the new system, Heidelberger will require only 1.6 years for the investment to pay back.

At Heidelberger's production site in Brandenburg an der Havel, the cooling lubricant circuit serving the grinding machines was driven by four fixed speed pumps with motor ratings of 37 kW each - representing a substantial share of the wsite's power consumption.

The analysis revealed that the old pumps were designed for an operating point significantly higher than needed, a set of downstream throttle valves was then used to reduce the flow rate (!)

Heidelberger decided to change the whole pump set for new pumps fitted with KSB SuPremE® motors. This allowed important savings: this decision is expected to decrease energy consumption by about 78% and to pay for itself in 1.6 years!
