2. Flexible Drain System

Flexible drain hose can cover most applications from continued submergence in 100% aromatics to 300 F hot tanks to Ethanol and Methanol applications. Flexible drain is designed to prevent kinking of the hose or pinching of the hose under the deck support legs.
CLAD HOSE
* The 'Clad Hose' type drain can be installed from center sump to shell even in the largest tanks with one continuous length or, for economy, can utilize the "shortest length" concept in conjunction with rigid piping.

FLEX HOSE
* The 'Flex Hose' type drain is installed with a 360° cil and can connect the sump nozzle to the shell nozzle (without rigid piping) in one continuous length regardless of tank size.
