Claim 0:
1. A pump assembly, comprising:
a first section including a first outer housing and a first drive shaft, wherein the first outer housing is generally cylindrical with an inner chamber and the first drive shaft is generally cylindrical with splines on an outer surface and a retainer bore;
a second section including a second outer housing and a second drive shaft, wherein the second outer housing is generally cylindrical with an inner chamber and the second drive shaft is generally cylindrical with splines on an outer surface and a pin bore;
wherein the first outer housing of the first section is mechanically coupled to the second outer housing of the second section;
a coupling assembly comprising a coupling, a thrust pin, and a retainer ring, wherein the coupling is generally cylindrical in shape with an outer surface and splines formed along an inner surface, wherein the retainer ring is generally a shaped wire wound into a circular shape and installed within a retainer groove within the retainer bore of the first drive shaft, wherein the thrust pin is generally cylindrical in shape with an upper portion, a lower portion, and installed into the pin bore of the second drive shaft;
wherein the coupling assembly mechanically couples the first drive shaft and the second drive shaft;
wherein the coupling is configured to transmit torque from the first drive shaft to the second drive shaft via the splines; and
wherein the thrust pin is configured to transfer tensile stress from the retainer bore in first drive shaft to the pin bore in the second drive shaft.
