Flow Range

Where shaft seal leakage is not allowable, for liquids
that are hard to seal, or where seal maintenance
is difficult, Viking Mag Drive® sealless SG pumps
are the solution. In this type of pump, a canister
hermetically seals the liquid within the pump. Inner
magnets are connected to the pump drive shaft
inside the canister, and an outer magnet assembly
rotates outside of the canister, driven by a motor or
other drive, so that magnetic forces pass through the
canister to the inner magnets and cause the drive
shaft to rotate. This eliminates traditional dynamic
shaft seals, and problems associated with them
(wear, leakage, air infiltration).

TYPICAL APPLICATIONS:
■t Fuels and Additives
■t Polyurethane Meter / Mix
■t Adhesive & Sealant Dispensing
■t Pipeline Sampling
■t Chemical Metering
■t Heat Transfer Oils

A hollow drive shaft allows some liquid to flow by
means of pressure differential from the high pressure
side of the pump through the shaft, into the canister
and back to the low pressure side of the pump.
This provides magnet cooling and prevents product
stagnation.
