The PHYM Foam Bladder Tank is to provide foam solution. It is mainly consist of bladder tank, capsule, proportioner, control valves, pressure gage and pipelines. High-pressure water is needed to swap out foam concentrate (stored in the capsule of the tank) from the tank as a certain proportion. The foam concentrate then mixed with pressurized water and form foam solution. For the capsule is separated from the pressure water that it can be utilized next time if not finished. Besides, there is feed inlet to refill or change the foam concentrate.

Working Principle:

When pressure water flow through the proportioner, a small part of water (3%~6%) flow into tank from water inlet and press capsule to swap out equal foam concentrate and mixed with another part of water (97%~94%) in proportioner. Foam solution flows out from outlet and was provided to foam generators or foam nozzles  (this part is not belong to the unit, you should buy extra) through pipelines.

Application:

The unit usually constitutes foam spray system and low/high expansion foam extinguishing system with pipelines, foam generators and foam nozzles. This unit provides foam solution for these systems through pipelines which are distributed in all destination areas and they are connected with generators or foam nozzles. The system works once there is fire somewhere and solution was transported to destination area through pipelines. Thus destination area gets foam solution to put out fire with foam generators or foam nozzles.

Characteristic:

1. Big flow pressure range and small pressure loss.
2. Widely used both in mid-multiples and low multiples foam extinguishing system.
3. Two types: horizontal and vertical.
