The right triplex pump for the shallowest to deepest drilling operations can be readily selected with a new eight-page guide from National Supply Company. The guide gives full physical dimensions and performance specification of the entire National triplex mud pump line. Five models are available from 500 to 1,600 input hp, all adaptable to a variety of drive arrangements. Each is compactly engineered for space savings and most efficient rig set-up and layout, says the guide. Text sections emphasize engineering features that improve durability, operating smoothness, ease of inspection and servicing.
