Pump rod connector apparatus and method

A connector assembly positioned about abutting ends of an extension rod and a piston rod of a reciprocating pump, the connector assembly comprising:

• a pair of outer clamp members and a pair of removable inner clamp members;
• wherein each of the outer clamp members receives one of the removable inner clamp members;
• wherein each of the inner clamp members has a pair of opposed inner surfaces, with one of said inner surfaces contacting a shoulder on the end of the piston rod and the other of said inner surfaces contacting a shoulder on the end of the extension rod;
• means for urging the outer clamp members toward one another, said means causing the inner surfaces of the inner clamp members to impart forces on the corresponding shoulders of the ends of the rods that urge the ends of the rods toward one another to enable a transfer of reciprocating motion from the extension rod to the piston rod;
• and
• a manifold bolted on to at least one of the outer clamp members to direct a fluid stream generally parallel to an axis of the abutting rod ends.
