Conventional tank maintenance poses significant challenges, especially with various chemicals. To address this, Poly Processing has pioneered a distinctive system aimed at reducing the risks inherent in traditional vertical tank upkeep. 

Poly’s Integrally Molded Flanged Outlet, known as the IMFO® system, integrates the flange seamlessly into the tank during the molding process, eliminating stress points. Unlike inserts added during or after production, the flange is formed from the same material as the tank, ensuring integrity and durability. 


  • With the flange positioned at the tank’s base, complete drainage occurs below the tank’s knuckle radius, potentially obviating the need for tank entry during cleaning procedures.
  • One-piece construction ensures the tank’s long-term performance by preserving the integrity and structural design of the tank hoop.
  • In aggressive operating environments, the entire flange face receives protection from the antioxidant OR-1000™ system.
  • facilitates the highest static head pressure, thereby contributing to the highest net positive head suction (NPHS) among vertical non-coned tanks.
