THE BASIC IDEA OF FIREMIKS-SYSTEM

A reliable, simple and self-regulating mechanical system driven by the existing water flow - no other energy source required. Accurate proportioning is made automatic, the FIREMIKS system adjust itself for changes in flow and pressure, without any calibration needed.

WORKING PRINCIPLE

FIREMIKS is flow driven. The water flow goes through the FIREMIKS positive displacement water motor. This generates an axial rotation, transferred to the dosing pump over the direct drive coupling.

Since the water motor functions both as a drive to the dosing pump and as a flow meter device, the system becomes by that flow proportional: dosing remains within approved tolerance regardless of variations in the water flow.

UNIQUE WATER MOTOR

Special designed volumetric water motor using 8-10 vanes extending from the rotor gives smooth rotation and volumetric function without using moving elastomer sealing.

SOME IMPORTANT INSTALLATION GUIDELINES

When installing FIREMIKS we strongly recommend that the concentrate tank minimum level is above the inlet of the dosing pump so that the concentrate has a free flow from the tank down to the dosing pump, this makes the suction efficient and immediate from the start. Gravity feed is a requirement when installing our piston pump type model - PP,

The internal diameter on the suction system must have an equal diameter, or one step larger, as the inlet of the  Selector valve Dosing/Flushing valve on the dosing pump. Consult Data sheet for each model for detailed recommendations.

FIREMIKS is designed to operate with clean water. No abrasive particles should be present in the water flow. Attention! Rinse the piping thoroughly before installing FIREMIKS to ensure that the extinguishing water is completely clean of waste products after welding, etc.

If the installation is to operate for an extended period of time with extinguishing water only, a by-pass with suitable valves should be installed around the FIREMIKS system to avoid unnecessary wear.

Dry running of the FIREMIKS dosing pump is not allowed, always use the internal flushing if suction of concentrate does not occur.

For fixed installations we recommend that FIRMIKS is delivered with a Dosing Return Valve (DRV) that makes it possible to return extinguishing media to the tank. This enables simple, fast and regular testing of the device’s functionality, including the ability to check the proportioning without wasting any concentrate.

WORKS WITH ALL COMMON NOZZLES

FIREMIKS works with all common types of nozzles, among others: Low-Ex, Medium-Ex and High-Ex nozzles, foam sprinkler heads, spray nozzles, foam monitors and foam chambers.
