Dimensionally interchangeable, seal-less pump

15 July 2008

Viking Pumps’ line of Universal Mag Drive series adds a seal-less option to the proven Universal Series product line. Dimensionally interchangeable footprint with Viking’s most popular Heavy Duty Bracketed packed and sealed pumps, the Universal Mag Drive Series provides a proven, simple solution for upgrading existing pumps. This seal-less pump features a thrust-controlled design that allows short-term run-dry capabilities and bi-directional pump operation for enhanced application flexibility.

Available in cast iron, steel and stainless steel, these sealless 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 260ºC (-60ºF to 500ºF). Capacities to 114 M3/Hr (500 GPM) will be available later this year.
