National Petroleum Oilfield Products (NPOP) serves as the Purvis oilfield division. Specializing in mechanical products for oil rigs and production, NPOP handles mud pumps, draw works, and other rig equipment maintenance items. Located in Houston and Odessa, NPOP has quality tier-one bearings, power transmission, and gearing products in stock and is focused on providing the quick service oil and gas require!

 

Mud Pumps - NPOP inventories bearings and seals for most mud pump makes and models, including the largest inventory of mud pump V-Belt sheaves, Q.D. bushings, and Kevlar belts. If we do not have the right sheaves for your application, we can make the selection and design your belt drive for single and dual traction motor drives, as well as independent diesel applications. We offer tensioning devices that get V-belt drives tensioned to spec, avoiding premature failures and shaft breakages.

 

DWWKS- NPOP inventories bearings, seals, and roller chains for all legacy DWWKS makes and models. We also inventory motor input gear couplings for legacy DWWKS, as well newer model gearbox driven DWWKS. If you need a sprocket and delivery is unacceptable, please give NPOP a call.  We can re-engineer the part through our AutoCAD services and have the part made on an expedited basis.  This service is also available on gear couplings. Give us a call and we will begin working on your breakdown immediately.

 

Crown & Traveling Equipment - We inventory Timken and Schaeffler (formerly FAG) sheave bearings with and without snap rings, as well as Clark seals. We also carry snap rings for 8", 10", and 12" sheave applications. We offer both Schaeffler and Timken completed sealed unitized sheave bearings.

 

Top Drive- NPOP carries an extensive inventory of top drive bearings, seals, and bearing isolators. We are happy to use our extensive knowledge of top drive bearings to assist you with new applications or to help you troubleshoot existing problems.

 

Iron Roughnecks - We inventory hundreds of parts iron roughnecks, including bearings and made-to-order machine parts.

 

Machining Capabilities - NPOP helps with designs for numerous applications that require made-to-order parts. From special hubs and shafts to exotic couplings and adapters, we are excited to work with you on making your plans a reality.
