A packing health monitoring system for a pump includes an isolation block arrangement having first and second connections, an integrated check valve, and means for securing the isolation block to a fluid end of the pump. A lubrication line which is coupled to a lubricant source connects to one of the first and second connections. A pressure sensor connects to the other for the first and second connections. The pressure sensor is configured to measure a back pressure within the fluid end. The packing health monitoring system further includes a control system in data communication with the pressure sensor; and an alert generator in data communication with the pressure sensor and the control system. The alert generator generates a first alert upon the control system determining the back pressure equals or exceeds a first predetermined threshold.
A pump, comprising:
A method of monitoring packing health in a pump comprising a fluid end having a bore hole and a plunger configured to pressurize fluid within the bore hole, a packing located between the plunger and a side wall of the bore hole, a packing lubrication system in fluid communication with the packing, the lubrication system having a lubricant source and a valve for selectively allowing flow of lubricant to the packing, a power end configured to provide reciprocating motion to the plunger, a packing health monitoring system comprising a pressure sensor incorporated into an isolation block connected to the fluid end between the bore hole and the valve for measuring a back pressure within the fluid end, a control system in data communication with the pressure sensor, and an alert generator in data communication with the pressure sensor and the control system, the method comprising:
