Abstract
Frac pumps have a fluid end and a fluid end block. The fluid end block has a plunger cylinder having a primary axis, a suction bore having a primary axis, a discharge bore, and a pump chamber. The pump chamber is defined by the intersection of the plunger cylinder, the suction bore, and the discharge bore. The fluid end block has a cylindrical portion extending along the primary axis of the suction bore. The cylindrical portion has a diameter greater than the diameter of the plunger cylinder. The pump chamber also has a ridge that extends radially inward from the walls of the pump chamber in a plane normal to the suction bore primary axis.
