Patent number: 8225694Abstract: A piston rod assembly for coupling between a power end and a fluid end of a high pressure reciprocating pump. Part cylindrical members are clamped together via pistons arranged orthogonally to the rod axis. The members grip the power and fluid end components in a knuckle joint or ball and socket. By providing orthogonal loading, a large contact area is obtained between the members and the components, which gives a mechanical advantage in keeping the parts together even when a maximum reciprocating force is applied by the pump.Type: GrantFiled: October 8, 2004Date of Patent: July 24, 2012Assignee: Spicket Valves and Pumps LimitedInventors: George Coulter Kennedy, Arnaud Fusilier

Publication number: 20120177517Abstract: A valve cap for sealing an aperture in a pump; a plugging assembly for a valve cap to seal at an aperture in a pump; a docking unit for use with a plugging assembly for sealing an aperture in a pump; and a method of sealing an aperture in a pump. A valve cap (10) comprises a valve plug (16) including, a first engaging means (40); a compression unit (20) including a plurality of springs (56) to apply a compressive load upon the plug and second engaging means (62, 64); a docking unit (24) for landing on the compression unit, including one or more pistons (92) to apply a compressive load upon said springs and third engaging means (74, 76, 78) to lock said plug to said compression unit and seal said plug against said aperture.Type: ApplicationFiled: December 12, 2011Publication date: July 12, 2012Applicant: SPICKET VALVES AND PUMPS LIMITEDInventors: George Coulter Kennedy, Guillaume Sourdois

Publication number: 20100236402Abstract: Apparatus and method for securing a cylinder liner to a pumping module. A first part of an assembly housing pistons is fastened to a pumping module and a second part of the assembly is brought against the first so that the pistons act on tensioning plates which each have a stud rod extending therefrom through the assembly at an end distal to the pumping module. Each rod has a first portion substantially surrounded in an elastomeric member and a second portion threaded to receive a nut. The rods are passed through a clamping ring on the cylinder liner and the nut is attached to the rod. Actuating the pistons causes initial compression of the elastomeric member by the tension plate and allows tightening of the nut toward the pumping module. Release of the pistons then causes expansion of the elastomeric member to urge the cylinder liner towards the pumping module.Type: ApplicationFiled: June 2, 2010Publication date: September 23, 2010Applicant: SPICKET VALVES AND PUMPS LIMITEDInventor: George C.

Patent number: 7656305Abstract: There is disclosed a monitoring system for monitoring alignment of a piston rod assembly of a reciprocating pump, such as those used to pump drilling mud in the oil and gas exploration and production industry. In one embodiment, a monitoring system is disclosed which is for a reciprocating pump (10) of a type comprising a fluid end component (20), a power end component (18), and a piston rod assembly (12) extending between the fluid and power end components. The monitoring system includes a number of sensors (52, 74) coupled to the piston rod assembly, for providing an output indicative that the piston rod assembly is experiencing bending stress, which occurs in the event that the piston rod assembly becomes misaligned, in use of the pump.Type: GrantFiled: November 22, 2005Date of Patent: February 2, 2010Assignee: Spicket Valves and Pumps LimitedInventor: George Coulter Kennedy
