‡@ See model numbering code on Page 3 of this brochure. Performance is the same for
SGN-05,-07 (ductile iron) models, or for SG-8_ _ _ _ (sealless mag drive models).
‡A Standard Buna-N seals (O-Rings and shaft lip seals) can be used from -40°F to +225°F
(-40°C to +107°C). With optional sealing elements of PTFE or Kalrez®, temperatures up
to +450°F (+230°C) are possible. Extra clearances may be required. Contact factory for
recommendations.
‡B UL 343 rating (-X) for fuel oil available.
‡C NPT standard. Consult factory for other port size or type options such as BSP, SAE
O-Ring or other.
‡D SAE J518 Code 61 flange with metric fasteners standard. Consult factory for other port
size or type options such as NPT, BSP, SAE O-Ring or other.
‡E Nominal capacity based on 100 SSU (22 cSt) liquid at 100 PSI (7 BAR)

Sealless magnetic drives are available on all SG and SGN pumps. Liquid is hermetically
sealed in a containment canister at the bracket end of the pump. Outer magnets are
positioned outside of the canister and are driven by the motor. Magnetic force passes
through the canister and turns inner magnets inside the canister, connected to the pump
drive shaft, to generate flow. Magnetic drives are especially useful for hazardous, volatile
or flammable liquids where leakage or vapors are not allowable, or for high inlet pressures
which would damage a shaft seal.
Contact your Viking distributor for assistance in selecting the right magnetic coupling for your
pump. Several different torque ratings are available (see table on right) depending on the
required flow, pressure and temperature. Neodymium Iron Boron magnets are used to +225°F
(+107°C), and Samarium Cobalt magnets are used to +500°F (+260°C). Magnetic couplings
offer either a long-coupled bearing carrier or NEMA or IEC face-mounted motor drive.
