Abstract
A lubricating system configured to provide a lubricating oil from a lubricant reservoir to a fluid end by use of a pump. The lubricating system has a plurality of check valves that each have an elastomeric insert. The lubricating system also has at least one pressure relief valve that is configured to re-rout lubricant to the lubricant reservoir when needed to stabilize pressure within the system. The lubricating system uses a pump drive controller and at least one sensor to selectively turn the pump on and off.
