Sweden-based pump manufacturer Concentric AB has been awarded a new development contract to supply high voltage electric coolant pumps for a battery-electric mining machine for an unnamed global original equipment manufacturer (OEM).

The company said the customer would use its e-pumps for cooling the batteries and power electronics on a large, fully electric mining machine.

It commented that battery-electric powertrains would be one of the key technology enablers for 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 as well as enable zero emissions.

Furthermore, it said the electric coolant pump would enable the use of a high voltage supply, eliminating the need for a low voltage DC converter.

It also includes a robust design and a wet rotor which would eliminate the possibility of a dynamic seal failure, and integrated diagnostics to monitor temperature and pressure.

Martin Kunz, president and chief executive officer of Concentric AB commented: "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."
