A centrifugal pump is a dynamic device that brings fluid into the center of the “impeller”, the impeller slings it outward and forces it into a diverging section called a diffuser or volute chamber.

During the 1950’s the Mission” 1780 type “W” pumps were introduced to replace duplex pumps while creating the first low pressure mud system. The use of a high quality concentric type centrifugal pump allowed abrasive fluids to be mixed and transferred while reducing initial and maintenance costs for the drilling industry. The low-pressure mud system with Mission 1 780 Type “W” centrifugal pumps became the industry standard.

As well depths increased so did the need for heavier mud weights. When the mud weight began exceeding 14 ppg the need for a pump that could withstand greater horsepower loads arose. During the 1970’s Mission organized a design team that engineered the Mission Magnum. The Magnum was designed to have the same footprint, flange locations, and drive shaft diameter as the 1780 “W”. This allowed a 1780 to be replaced by a Magnum without any skid modifications. The Magnums were originally engineered with a 2-1/2″ shaft (3″ between the bearings), double row bearings with an engineered life of over 2 years at 200 HP, larger impellers and heavier frames. The Magnum allowed drilling contractors to upgrade their centrifugal pumps and mix heavier fluids.

The National Oilwell Varco” Mission centrifugal pump line has proven to be the best centrifugal design for handling abrasive mud. This pump line offers a broad selection of innovative features for a variety of routine, demanding, abrasive and corrosive applications. These pumps are designed for a wide range of flow rates, from a few gallons per minute to thousands of gallons per minute.

Each pump contains the finest materials, engineering and craftsmanship available in the industry. Described are like features of these pump lines and unique features are described on the following pages.

National Oilwell Varco utilizes unique design features developed for slurries. Three major differences from most pump designs include the concentric casing, wider impellers and increased re-circulation areas. Each feature contributes to reducing wear when handling abrasive fluids.

All of the pumps feature a concentric casing. This casing averages 37% thicker than conventional pump casings, and up to 50% thicker for the larger, mud pumping models. They are pressure rated at 1 .5 times the flange rating and are designed with a 1 /8″ erosion allowance. The concentric style casing has proven to offer the greatest pump life and reduced downtime. The walls of a concentric style casing are an equal distance from the impeller throughout the impeller circumference, which results in a smooth flow pattern. A volute style casing has a cutwater point that disturbs the fluid flow pattern creating an eddy. The concentric casing eliminates vibration, turbulence and aeration that is caused by the cutwater point in conventional volute pumps. It also reduces the high bearing loads and shaft deflection even at near shutoff flows.

The shaft is much larger in diameter than conventional pump shafts for heavy-duty performance, minimum deflection and increased operating life of the seal or packing. With a 2-1/2″ diameter at the seal area and 3″ diameter between the bearings these pumps can be direct connected or belt driven.

Tobee® Mission Magnum I Pumps are proven as reliable, heavy-duty, low-cost slurry pumps. The 3×2×13 through 8×6×14 pumps all feature the same power end, which ensures production and reduced spare-part inventory requirements. The Mission MAGNUM I has been engineered for the toughest jobs in drilling, production, well-servicing, and industrial applications. The MAGNUM I is more powerful, more durable, and easier to maintain than any conventional pump in use today.

The Magnum has an open impeller design that contains wide-tipped vanes and a more tangential circumference of the suction allowing the pump to create a smoother flow pattern when handling abrasive fluids. The Magnum is available in Magnachrome™, hard iron, stainless steel, and aluminum bronze fluid ends. The pumps can be unitized with electric motors, diesel engines, and hydraulic motors (horizontal, vertical, or close-coupled configuration).

Used Gardner Denver PAH 4 1/2 x 8 Triplex Mud Pump Package, 4.5" Metal plungers x 8" stroke, Detroit 8V-71 diesel engine, manual transmission, hydraulically driven Harrisburg 3x4 charge pump, 5 valve reversing manifold & piping, plunger lubricator, Oteco relief valve, mud gauge, make up air compressor on engine, fuel tank, hydraulic oil tank, parts cabinet, lights, Ruffneck heater, etc. packaged on heavy duty I-beam sub skid with steel pump house, 2124 Hrs showing, 28" long x 10" wide x 9" high

The 2,200-hp mud pump for offshore applications is a single-acting reciprocating triplex mud pump designed for high fluid flow rates, even at low operating speeds, and with a long stroke design. These features reduce the number of load reversals in critical components and increase the life of fluid end parts.

The pump’s critical components are strategically placed to make maintenance and inspection far easier and safer. The two-piece, quick-release piston rod lets you remove the piston without disturbing the liner, minimizing downtime when you’re replacing fluid parts.
