Abstract
An apparatus is given for feeding a lubricating and cooling material to a pump or other device having a rotating member that operates intermittently. In particular it deals with methods for delivering lubricant to the pump whenever, and only whenever, the pump is running and with ensuring that the pump is always adequately lubricated when it is running. It is particularly useful for centrifugal pumps on mobile equipment, such as pumps used in cementing in the oil industry.
