Abstract: A reciprocating pump system for replacing a removable packing bore, the system includes a fluid end and a pump drive end. The fluid end includes a fluid inlet, a fluid outlet, a working barrel, a reciprocating member disposed in the working barrel, and the removable packing bore disposed within the working barrel. The pump drive end includes a gearbox integrally connected to a crankshaft, a crosshead, a transverse member configured to oscillate the reciprocating member of the fluid end in transverse motion. The removable packing bore and the transverse member are each configured to be connected to a packing bore connector.

Abstract: A monitoring system for reciprocating pump having a plunger connected to a crankshaft by a crosshead and connecting rod assembly. The monitoring system includes a plurality of wireless temperature sensors which each have a temperature probe connected to a sensor head, a plurality of antennas which each have an antenna head configured to communicate wirelessly with a corresponding one of the sensor heads, and a signal processing unit connected to the plurality of antennas. Each temperature probe is positioned in contact with a corresponding crank pin bearing, wrist pin bearing or crosshead bearing. Each sensor head is mounted to the crosshead, and each antenna head is mounted to the pump at a location in which communication is enabled between the antenna head and its corresponding sensor head when the crosshead reaches a first position during each reciprocation of the crosshead. In operation, each antenna head transmits a radar pulse which is reflected by its corresponding sensor head, the reflected pulse is received by the antenna head and communicated to the signal processing unit, and the signal processing unit determines the temperature of the sensor head from the reflected pulse, which temperature is indicative of the temperature of its corresponding monitored bearing.
