 Top Pourer Foam Maker-TPFM

Application

The GPE Top Pourer Foam Maker (TPFM) is designed for use in foam systems for the protection of flammable liquid storage tanks and combine foam generation, vapor sealing and foam pouring in a robust, low-maintenance integral unit.

Features and Benefits

There are four basic body sizes with capacities ranging from 75 to 3,300 liters/min. at inlet pressures between 3 and 10 bar g. Each unit is factory calibrated to perform at a fixed flow and pressure point within the limits shown over its name plate. Then the system is therefore able to make the most cost effective use of available water and foam concentrate resources. The discharge characteristics of the TPF are enhanced by the deflector plate fitted to the outlet which disperses the finished foam against the tank interior shell. This ensures a rapid spread across the surface of the tank content, whilst lowering the application velocity to reduce contamination of the foam by the tank content.

TPF units are fitted with a unique bursting disc fabricated from impregnated graphite to seal the tank and prevent vapor loss. Graphite is used to ensure that the disc will burst when subjected to the pressure of foam entering the top chamber but will not burst during normal tank operations such as filling and discharging. The use of graphite enables the bursting pressure to be held within tolerances of ± 0.05 bar (± 0.75 Psi).
