Patent number: 11746775Abstract: A power end frame assembly for a reciprocating pump that includes a first and second end plate segment each including annular bearing support surfaces configured to support a crankshaft bearing assembly. At least one middle plate segment is disposed between the first and second end plate segments and includes an annular bearing support surface configured to support a crankshaft bearing assembly. The annular bearing support surfaces of the first and second end plate segments and the at least one middle plate segment each have a diameter and are coaxially aligned. The diameter of at least one of the first and second end plate segments is different from the diameter of the at least one middle plate segment to facilitate insertion and removal of the crankshaft bearing assembly from the power end frame assembly.Type: GrantFiled: October 1, 2018Date of Patent: September 5, 2023Assignee: SPM Oil & Gas Inc.Inventors: Jacob A. Bayyouk, Edward C. Kotapish, Chandu Kumar, Donald Keith Plemons, Benjamin D. Engstrom

Patent number: 11421682Abstract: A dual circuit lubrication system for a power end of a reciprocating pump that includes a lubrication pump that supplies lubrication fluid to a high pressure lubrication circuit and a low pressure lubrication circuit. The high pressure lubrication circuit is fluidly coupled to a crankshaft to supply lubrication fluid to journal surfaces associated with the crankshaft at a first lubrication fluid pressure. The crankshaft drives a crosshead coupled to a plunger to displace fluid from a fluid end of the reciprocating pump. The low pressure lubrication circuit is fluidly coupled to supply the lubrication fluid to a plurality of roller bearing surfaces associated with the crankshaft at a second lubrication fluid pressure. The first lubrication fluid pressure is greater than the second lubrication fluid pressure.Type: GrantFiled: May 29, 2019Date of Patent: August 23, 2022Assignee: SPM Oil & Gas Inc.Inventors: Joseph H. Byrne, Edward C. Kotapish, Scott Skurdalsvold, Jacob A. Bayyouk, Lawrence Waweru

Patent number: 8998168Abstract: A valve has a body having a rotatable valve element. A drive mechanism has a drive input member and a drive output member that are coupled to the valve element for rotating the valve element. A shear member is operatively located within the drive mechanism between the drive input member and the drive output member for shearing in the event the force to rotate the valve element is excessive. The valve has indicia indicating open and closed positions for the valve element. An indicator is mounted to output drive member to properly align with the indicia regardless whether the shear member has sheared or not.Type: GrantFiled: June 14, 2013Date of Patent: April 7, 2015Assignee: S.P.M.
