UMD – Universal Mag Drive

VIKING Universal Mag Drive® Internal Gear Pumps
Sealless, Industrial Duty Pumping for Crucial Liquid Containment Applications

Viking's Universal mag-Drive (UMD) pumps are dimensionally interchangeable with current Viking Universal Series pumps and other competitors. Due in part to the multiple port configurations and sizes that Viking has available, this allows easy upgrade from a packed or mechanically sealed pump to a sealless design without the added cost of re-piping. Elimination mechanical seal replacement and associated maintenance costs reduce downtime and significantly reduce total cost of ownership.

How we designed the UMD to address “Customer Benefits”

Cost effective sealless pump
Cost reductions average over 30% vs. existing mag drives and are reasonably priced above the cost of double seals with barrier systems, alarms, etc.

Minimize installation costs
No re-piping costs required when upgrading from packing or mechanical seal to sealless. Directly interchangeable with existing Viking U-Seal and Heavy Duty Series, along with many other competitor pumps.  Often can use existing gearbox, motor, base, coupling and guards.

Improve tolerance to accidental dry-run operation
Designed to tolerate temporary run-dry conditions if the internal components have been wetted.  Carbon graphite bushing and hardened cast iron / silicon carbide thrust washers have very good run-dry characteristics.  Heat build-up from eddy currents in magnet assembly only starts to be an issue above 1000 rpm.

Ease of maintenance
Make product more maintenance friendly by standard lifting eye & jacking screws permit pump assembly and disassembly without risk of injuries to fingers.  Simple, modular construction that does not need special tools makes maintenance fast and easy.

Provide reversible operation
Rotor support system and dual thrust control allows the pump to be operated in either direction without modification or pump disassembly. Allows for loading or unloading using one pump. Lowering system cost. It also locks rotor axially in place preventing contact with pump head during system upsets and regardless of rotation.

Bearing failure protection
Added to outer magnet assembly to prevent contact to canister in the event of a bearing failure.

Multiple port configurations, material and jacketing options
Wide array of pump materials available for internal and external components to match applications needs lengthens life of pump and lowers total cost of ownership. Also many port sizes, types, ratings, integral jacketed casings and jacketed heads are available as options. Provides easy solution to match customer requirements.
