Concentric AB signs pump supply contract for Euro truck engines

Concentric AB, a fluid engineering company specialising in diesel engine pumps and niche hydraulic systems, has signed a multi-year contract with a global truck manufacturer to supply oil and variable flow water pumps for its new 11 litre engine which is designed to meet the requirements of Euro 6/EPA13 legislation.

This contract follows on from an earlier order, announced in October 2012, from the same customer for water pumps on its 13 litre engine. Volumes of all pumps will ramp up throughout 2013 in time for 1 January 2014, when Euro6 legislation comes into force, with mature volumes on both contracts anticipated by late 2014 / early 2015.

Concentric says it has undertaken a significant investment programme to ensure that its oil and water pumps will be delivered ready for the introduction of the 11 litre engine at the start of 2014. Both water and oil pumps have been designed and developed by Concentric in close collaboration with the customer.

The water pump is a two-speed pump, controlled by an advanced magnetic clutch from Licos Trucktec, which was acquired by Concentric in June 2013. The resulting assembly not only gives the end-user a 1% improvement in fuel economy, which is a major advance for truck operators, but also demonstrates the synergies resulting from the marriage of Licos and Concentric technologies.

As with the 13 litre engine, thermostats are integrated into the Concentric water pump module, along with integrated water filtration and a single-piece injection-moulded impeller. The oil pump is an external gear pump construction, providing an excellent balance of high efficiency and durability.
