Meter Mixers of Foam Generator EI MXC-MIXER

Foam mixers depending on the inner diameter are divided into: EI-MXC-MIXER – in size of 2"½ (with nominal diameter of the calibrated diaphragm for water of 65 mm); EI-MXC-MIXER – in size of 3" (with diameter of 80 mm); EI-MXC-MIXER – in size of 4" (with diameter of 100 mm); EI-MXC-MIXER – in size of 6" (with diameter of 150 mm); EI-MXC-MIXER – in size of 8" (with diameter of 200 mm); EI-MXC MIXER – in size of 10" (with diameter of 250 mm) and have a discharge capacity of from 100 up to 10 740 l/min. Upon the customer's request, the capacity can be increased up to 18,000 l / min.

For these foam mixers you can use any foam generators with a viscosity of no more than 200 mm²×-¹.

Principle of operation of foam mixer EI-MXC-MIXER in assembly with dosing tank EI-MHS is based on the displacement of the foam generator with water pressure and subsequent mixing of the two streams in the ratio specified by the area ratio of the holes of calibrated diaphragms. At the entrance to the mixer water is divided into two streams: a large part of the water flows into the foam mixer through a calibrated diaphragm for the water, the other - is drained through the side tube inside the tank, creating a compression on the whole surface of the flexible container and displacing the foam generator through the pipeline with a calibrated diaphragm into the foam mixer. Elastic membrane prevents mixing of the foam generator with water within the tank.

The foam mixer is fitted with a calibrated diaphragm on the water supply line and a calibrated diaphragm with a check valve in the supply line of the foam generator which prevents mixing of the water inside the tank. This device is guaranteed to provide a receiving of a 1.3 or 6% solution, depending on the internal diameter of the mounted diaphragm. Upon the customer's request, the mixing ratio may be changed in one way or another (from 0 up to 20%).

A straight section of the foam solution supply piping in length of no less than 1 m should be foreseen during the design.
