ABSTRACT:
A manifold for a front-discharge fluid end reciprocating pump. The manifold comprises tubular portions which are connected to ports on the pump by threaded engagement of a plurality of nuts. The manifold has a center portion and at least one branch portion which intersects the center portion. Another tubular portion having a ported end is in communication with the center and branch portions and provides an outlet for the manifold. At least one nut on the manifold is a standard nut having lugs extending therefrom adjacent to an outer surface of the nut. A special nut is used on at least one of the connections and has lugs extending adjacent to the inner surface thereof. The lugs on the special nut have a longitudinal thickness less than the nuts on the standard nut. In this way, the nuts may be engaged with closely adjacent ports on the pump without interference of the lugs on the nuts with one another.
