Concentric has been on the receiving end of a new development contract for the supply of high voltage electric coolant pumps to a battery-electric mining machine.

The global construction OEM customer will use the e-pumps for cooling the batteries and power electronics on a large fully electric mining machine.

Electric battery-based powertrains will be one of the major tech enablers for the goal of zero emissions from off-highway machines.

Mining machines are one of the early adopters of this technology as construction OEMs expect their customers will enjoy a reduction in the total cost of ownership and enable zero emissions.

The electric coolant pump has the following key benefits:

· Enables the use of high voltage supply, eliminating the need for a low voltage DC converter;    
· Robust design which includes a wet rotor eliminating the possibility of a dynamic seal failure;           
· Long service life aided by liquid-cooled electronics and DC brushless design giving service life >50,000 hours;           
· Integrated diagnostics and utilizing sensors for temperature and pressure; and           
· Compact and low noise characteristics.

Martin Kunz, President and CEO, Concentric said, "This new agreement is another innovation milestone in the development of Concentric's e-pumps. We already supply e-pumps to many global OEMs for their hybrid and battery electric vehicles, this important contract will enable the development of a high voltage pump in the expected growth area of battery electric off-highway machines."
