National Oil well Varco’s line of Magnum Centrifugal mission pump is proven as reliable, weighty duty, low cost slurry mission pumps. Magnum centrifugal mission pumps have been world leaders in the drilling industry since their inception in the 1970’s. The 3x5x14 through 10x7x15 mission pump sizes all feature the same control end. By exploiting the same control end, these mission pumps can be providing at a low cost, and customer’s spare parts list requirements are greatly abridged. Featuring a concentric casing design coupled with wide vane impellers. The mission pump functions of Magnum centrifugal mission pumps exhibit reduced wear and increased mission pump life. Extended mission pump life reduces maintenance costs and, more outstandingly, reductions downtime and service supplies. Concentric casings remove vibration, turbulence, and aeration caused by the cutwater point in conservative volute mission pumps. Commotion and aeration produce eddy that cause excessive wear when handling abrasive fluids. The concentric of shear pump casings also reduce the high bearing load and shaft deflection present in other projects, even at near shutoff currents.

Here are the functions of mission pump. It removes the coarse jetting effect that is present with narrow impellers. The distance between the impeller tip and the casing is greater than shear pump, resulting in an increased re-circulation area. The entrance shape of the impeller vanes is more peripheral to the perimeter of the suction, creating a flatter flow pattern. Flat flow patterns are crucial when handling abrasive fluids at the shear pump. It also is the special design of the mission pump functions.

In addition to the higher fluid end features, Magnum centrifugal mission pumps are fortified with a heavy-duty shaft bearing meeting. The bearing meeting is the major of the mission pump functions. These are as important as the shaft. The shaft, larger in width than conservative mission pump shafts, provides heavy-duty presentation, minimum refraction and amplified operating life of the seal or packing. With a 3?” width at the seal area, and a 4”diameter between the bearings, these mission pumps can be direct linked or tie driven. This die driven is to make sure shear pump is safe enough for working. Forward front and rear bearing design decreases both radial and thrust lots. Magnum centrifugal mission pumps and shear pump are accessible with hard iron, Magna chrome stainless steel and aluminum bronze liquid trimmings.

National Oil well Varco offers both bare mission pumps and customized packaging of shear pump . Years of knowledge in unitization design and assembly allow quick response to customer needs. Magnum mission pumps can be combined with electronic motors, diesel engines and hydraulic motors in a level, vertical or close coupled shape. National Oil well Varco employments practiced personnel to assist clienteles with sizing and connection procedures.

With this knowledge of the mission pumps you can easily to find suitable pumps for you.
