Griswold E, F & G Series Pump





Close-Coupled or Frame-Mounted Configurations

E,F&G 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, E,F&G 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.
