19123-01-30A Casing is an important Wear Parts for Mission Magnum 6x5x14 Centrifugal Pump. 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 /8â?³ 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 Mission MAGNUM I has been engineered for the toughest jobs in drilling, production, well-servicing, and industrial applications. The revolutionary design of the MAGNUM I provides supreme-duty performance in all types of fluid pumping operations. Although it offers greater capacity and higher heads, the MAGNUM I remains the competitive pump of choice for aggressive applications. The MAGNUM I is more powerful, more durable, and easier to maintain than any conventional pump in use today.
