Available in cast iron, steel and stainless steel, these seal-less pumps eliminate seal leakage and environmental concerns, along with downtime due to seal replacement. They are ideal for hazardous, hard-to-seal liquids or for applications where very 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 thanks to Viking’s in-canister bushing and hollow shaft design, which generates positive internal cooling flow.
The Universal Mag Drive series offering includes multiple port location options, sizes, types and ratings including threaded, flat- and raised-face flanged. Jacketing options are also available. This series of pumps currently offers flow rates of up to 45 m3/hr (200 gpm), with pressures to 14 Bar (200 psi) and at temperatures ranging from -51ºC to 260°C (-60ºF to 500ºF). Capacities to 114 m3/hr (500 gpm) will be available later this year.
