Abstract
A pump system is provided where low pressure (4) and high pressure (6) pumps are coaxially mounted to receive motive power from a shared drive (300). The drive shafts are arranged such that one extends within a void in the other and both have shear regions such that, in the event of torque overload, either shaft can shear so as to disconnect the drive to it's associated pump while the other pump and shaft can continue to work.
Claims11
A pump system comprising a first pump for providing a first flow of liquid for use within a cooling lubricant system, and a second pump for providing a second flow of liquid, wherein the pumps are drivingly connected via respective coupling elements and arranged such that failure of the second pump resulting in it requiring an increased torque at an input to the pump causes the second pump to be drivingly disconnected from the input element.
