Abstract:
A wear sleeve is removably mounted on a piston rod. The piston rod includes a piston cap, a piston rod body, and a piston head, with at least one of the piston cap and the piston head being removable from the piston rod body. The wear sleeve is disposed over the piston rod body and prevents the piston rod from contacting dynamic seals disposed within a pump. The wear sleeve is mechanically secured in a cylindrical recess on the piston rod between a cap shoulder of the piston cap and a head shoulder of the piston head.

Claim (Index 13):
A pump comprising:\n a cylinder having an upstream end and a downstream end; a dynamic seal mounted in the cylinder; and a piston extending into the cylinder and through the first dynamic seal, the piston configured to reciprocate within the cylinder and relative to the dynamic seal, the piston comprising:\n a piston rod body elongate between a first end and a second end; \n a piston cap connected to the first end, the piston cap including a cap shoulder extending radially relative to the first end; \n a piston head connected to the second end, the piston head including a head shoulder extending radially relative to the second end; \n a cylindrical relief extending around the piston rod body and between the cap shoulder and the head shoulder; and \n a wear sleeve mounted on the piston rod body within the cylindrical relief; \n wherein the piston rod body is removably connected to at least one of the piston cap and the piston head; and \n wherein no portion of the piston besides an outer surface of the wear sleeve contacts the dynamic seal during reciprocating pump strokes of the piston within the cylinder.
