Abstract:
1. A fluid end assembly for a high pressure pump for receiving a fluid from a fluid supply manifold and supplying the fluid to an outlet manifold comprising: a first section; a plunger bore extending into said first section and oriented along a first centerline, said plunger bore configured for receiving a reciprocating plunger, a discharge section formed in said first section, said discharge section having a discharge passage and a valve chamber, said discharge passage intersecting said plunger bore, said discharge passage oriented along a second center line, said second centerline being coplanar with said first centerline and intersecting said first centerline at a first reference point to define a first obtuse angle λ; a suction passage, said suction passage intersecting said plunger bore, said suction passage oriented along a third centerline, said third centerline being coplanar with said second centerline and first centerline and intersecting said first centerline at a second reference point so as to define a second obtuse angle α; a second section; an inlet opening through a surface of said second section; a suction port in said second section and a valve chamber in said second section, said valve chamber down stream of said suction inlet, said suction passage downstream of said suction port and said inlet; wherein said second section is removably attached to said first section.
