Abstract
A suction manifold unit for mounting on a pump fluid end in association with at least one further suction manifold unit to provide a suction manifold assembly for supplying fluid to suction cylinders of such a pump fluid end. The manifold unit has at least one supply duct leading to its interior, and outlet duct for leading fluid from the supply duct to a suction cylinder during use, and a supply conduit sealingly associated with the supply duct, the supply conduit being adjustable between a retracted position where it will be spaced from another manifold unit mounted relatively to such a pump fluid end, and an extended position for engaging sealingly with a corresponding supply duct of such a further manifold unit to place the manifold units in communication with each other.
