850 Series pumps are provided with NEMA JM or JP close-coupled motors. As an alternative, Griswold offers flexible couplings to electric motors, including open drip-proof, totally-enclosed and explosion-proof motors, or engine, steam turbine, and belt-driven options.
Seal Options
While our standard mechanical seal is comprised of carbon/ceramic/Buna, we also offer alternatives for more abrasive/corrosive and high-temperature applications.
Coating Options and Baseplate Mounting Systems
For corrosion protection, 850 Series pumps can be coated on the interior and/or exterior with 3M™ Scotchkote™ 134 Fusion Bonded Epoxy. Griswold also offers a complete range of pre-engineered channeled steel baseplates to reduce stress and vibration.
