Mission pump is widely applied to drilling industry. The low-pressure slurry system with mission pump is proved to be the industry standard. You may wonder why so many enterprises choose Mission pump. Then I’d like to introduce the features and advantages of mission pump to you.
Each mission pump comprises the best materials, engineering and technology available in the industry. The special design features of mission pump are developed for mud. Three primary differences from most pump designs comprise the concentric casing, wider impellers and incremental re-circulation areas. Each feature is help to decrease wear and tear when dealing with abrasive liquids.
All the mission pumps have a characteristic that a concentric casing pipe is an average of 36% thicker than other ordinary pump casing pipes, and the larger mission pump models can even up to 50% thicker. Their pressure rate is at 1.6 times the flange rating and is developed with a 0.125 erosion allowance. The concentric casing pipe of mission pump has been proven to provide the longest service life and decreased shutdown time. The walls of a concentric casing pipe are an equal distance from the impeller though out the impeller periphery, which leads to a glossy streaming model. A volute casing pipe has a cutwater point that blocks the liquid streaming model forming a vortex. The concentric casing pipe of mission pump removes vibration, turbulent flow and aeration that are given rise to the cutwater point in ordinary volute pumps. It also decreases the high beating loads and axle lean even at near shutoff flows.
The impeller originality of mission pump has larger vanes at the pointed end which reduces the speed of the liquid quitting the impeller. This removes the abrasive jetting influence that is present with narrow impellers. The distance between the impeller tip and the casing pipe is larger leading to an incremental re-circulation areas allow the quitting liquid to mix with the re-circulating liquid reducing turbulent flow and wear. The entrance shape of the impeller canes is more tangential to the periphery of the suction creating a glossier steaming model. Smooth flow is vital when handing abrasive fluids.
The shaft is much larger in diameter than ordinary pump shafts for heavy-duty function, minimum lean and incremental operating life of the seal or packing. With a 2.5’ diameter at the seal region and 3’ diameter between the bearings, mission pump can be immediate connected or belt driven. The shaft region under the packing is safeguarded by a substitution, hook type bushing with one end free to extend with temperature alteration. This bushing can be substituted in the field without shaft removal. The outboard bearing is a duplex set of angular touch bearings with high thrust burthen volumes and zero endplay. This bearing set features 24 large balls that are preloaded so that each beating carries an equal load. Mission pump adopts an inboard bearing that is a single row roller bearing with high radial load volumes. This bearing was chosen to take the place of the formerly utilized double row bearing.
