Easy Change Pump Plunger

A reciprocating element assembly comprising:

• a reciprocating element adapter having a reciprocating element end opposite a reciprocating element clamp end;
• a reciprocating element, wherein the reciprocating element is cylindrical and comprises a reciprocating element adapter end opposite a front end, wherein the reciprocating element adapter end of the reciprocating element can be coupled to the reciprocating element end of the reciprocating element adapter;
• and
• a reciprocating element clamp, wherein the reciprocating element clamp has a first contact surface perpendicular to a central axis of the reciprocating element clamp and a second contact surface tapered relative to the central axis of the reciprocating element clamp and is configured to couple a first component and a second component via contact of the first contact surface of the reciprocating element clamp with a portion of the first component and contact of the second contact surface of the reciprocating element clamp with a portion of the second component, and wherein the first component or the second component comprises the reciprocating element adapter.

A method of servicing a wellbore, the method comprising:

• fluidly coupling a pump to a source of a wellbore servicing fluid and to the wellbore, wherein the pump comprises:
• a pump fluid end and a power end, wherein the pump fluid end comprises:
• a reciprocating element assembly comprising a reciprocating element adapter having a reciprocating element end opposite a reciprocating element clamp end;
• a reciprocating element, wherein the reciprocating element is cylindrical and has a reciprocating element adapter end opposite a front end, wherein the reciprocating element adapter end of the reciprocating element can be coupled to the reciprocating element end of the reciprocating element adapter;
• and a reciprocating element clamp, wherein the reciprocating element clamp has a first contact surface perpendicular to a central axis of the reciprocating element clamp and a second contact surface tapered relative to a central axis of the reciprocating element clamp, wherein the pump assembly is in an assembled configuration in which the reciprocating element adapter end of the reciprocating element is coupled to the reciprocating element end of the reciprocating element adapter, and wherein the reciprocating element clamp couples the reciprocating element clamp end of the reciprocating element adapter in contact and aligned with a reciprocating element clamp end of a pushrod of a pump power end, whereby a central axis of the reciprocating element is parallel to or coincident with a central axis of the pushrod;
• and wherein the pump power end is operable to reciprocate the reciprocating element within a reciprocating element bore of the pump fluid end;
• and
• communicating wellbore servicing fluid into the wellbore via the pump.
