Viking Pumps' new line of Mag Drive Magnum sealless pumps features a thrust-controlled design that allows short-term run-dry capabilities. This design all but eliminates damage resulting from priming and accidental empty tank situations. These cast-iron, reversible-direction-of-flow pumps are ideal for hazardous or hard-to-seal liquids, or for applications where low maintenance is a requirement. The adjustable rotor clearance enables high volumetric efficiency, whether pumping thin or viscous liquids.
Extended pump life is made possible by Viking's in-canister bushing and hollow shaft design. The pump's construction permits positive cooling flow that minimizes the potential for thermal product degradation. A patent-pending barrier fluid option is also available. This feature allows a fluid flush or barrier fluid to remove heat and keep pumped fluid out of the canister.
Additional features of the Mag Drive Magnum series include a close-couple motor flange option and the ability to run at synchronous motor speeds. This series of pumps offers flow rates of up to 200 gpm, with pressures to 200 psi at temperatures ranging from -60° to 500° F ( -51° to 260° C).
