Frequently asked questions about our pumps | FIREMIKS®

Q: Can we apply several different types of nozzles to a FIREMIKS?

A: Yes, you can use for example spray nozzles, Low- Medium- or High-EX devices, or any other type of nozzle at the same time as long as they are designed for roughly the same nominal pressure.

Q: Can we use different and varied feed pressures to the FIREMIKS?

A: Yes, the admixture is practically independent of the inlet and back pressure in the system.

Q: Can we distribute a correct concentrate solution to a nozzle placed on a 40-meter high raised platform?

A: Yes, the FIREMIKS can cope with heights up to 50 meters if the inlet pressure to the FIREMIKS from the main pump is 12 bar. Pressure drop over FIREMIKS 1-2 bar, 50 meters height 5 bar, leaving about 5 bar for hoses and nozzles.

Q: What length of hoses can we use downstream the FIREMIKS?

A: You can use whatever length you want or need since the length doesn’t affect the function of the FIREMIKS.

The crucial factor is having an adequate pressure of the water from the main water pump so the water/concentrate solution can be transported to the nozzle at the required flow and pressure.

Q: Can we divide the hoses and use several nozzles positioned in different lengths and heights from the FIREMIKS?

A: Yes, there are no problems with this; it creates practically no effect on the dosing rate. You may also close and open these nozzles independently of each other. See also crucial factor in previous answer.

Q: Does the FIREMIKS function even with high-viscosity Alcohol Resistant foam concentrates and low-viscosity wetting agents?

For more information, please visit our website.

A: Yes, FIREMIKS can be adapted to all common types of concentrates, on request please specify which type of extinguishing concentrate, dosing rate and its viscosity, and we will offer you the FIREMIKS type that is optimally adapted to your choice. The general rule is that the gear pump (-GP) is best suited for high-viscous concentrates and a piston pump (-PP) is best suited for low and medium viscosity.

Q: Can we install a FIREMIKS in an existing water sprinkler system?

A: Yes, you only have to install the FIREMIKS somewhere suitably between the main pump and sprinkler heads and connect it to an atmospheric concentrate tank. The optimum FIREMIKS for sprinkler systems is our piston pump type – PP.

Q: Can we use FIREMIKS in a deluge system?

A: Yes, it works perfectly. Deluge systems are designed for a certain flow/pressure, with a FIREMIKS you have an increased safety margin if the system for any reason occasionally does not keep this intended flow/pressure. A suitable FIREMIKS for deluge systems is normally our gear pump type – GP.

Q: Do we need a pressure tank for the concentrate supply?

A: No, just a normal atmospheric tank is needed, you may well use the container from the extinguishing media concentrate supplier.

Q: Can we install two FIREMIKS in parallel?

A: Yes, that is not a problem; you can even install 3-4 units in parallel as long as you create a harmonic flow in the pipes and you keep the required min. flow of each unit.

1. What is a Chemical Metering Pump?

A Chemical Metering Pump is a specialized pump used to meter and pump various types of corrosive and hazardous chemicals at precise flow rates. These pumps can be manually or automatically adjusted, and are typically low-flow pumps used in applications such as wastewater treatment, water treatment, and air pollution control to meter the necessary amount of chemicals. Chemical Metering Pumps are commonly used in water treatment and wastewater treatment applications.

2. Types of Chemical Metering Pumps?

– Piston Chemical Metering Pump: This type of pump has a pump chamber in the form of a cylinder and the forward and backward movement of the piston within the cylinder regulates the flow rate. The pump’s flow rate can be adjusted by changing the stroke length or the frequency of the piston. Piston Chemical Metering Pumps are commonly used for pumping non-corrosive liquids without solids and for high-pressure systems.
Diaphragm Chemical Metering Pump: This type of pump is used for applications that require precise measurement of liquid flow rate. It mainly uses a diaphragm pump (usually made of rubber, but can also be made of other materials depending on the liquid being pumped). Diaphragm metering pumps have many advantages: they allow for flow rate adjustment from low to high as required, have a sealed structure and do not leak fluid, have a simple pump structure, and only have a few moving parts which makes them long-lasting with minimal maintenance.

Hydraulic Diaphragm Chemical Metering Pump: This type of pump has a pump chamber that is separated into two compartments by a flat energy barrier made of rubber or plastic. The first compartment is the auxiliary chamber, located between the diaphragm and the piston. The second compartment is the main chamber, located between the pump head and the diaphragm and acts as a diaphragm pump chamber. The movement of the diaphragm creates suction or discharge of the liquid that needs to be pumped.

Electromagnetic Chemical Metering Pump: This type of pump is used for treating inorganic sludge such as semiconductors, circuits, metals, etc. It is commonly used in industrial chemical sludge treatment as well as in food processing for items such as beer, dipping sauce, and beverages. This pump is also widely used in industrial and food processing wastewater treatment.

Electromagnetic Dosing Pump: This type of dosing pump is used in the treatment of inorganic sludge such as semiconductors, circuits, metals, etc. It is often used in the treatment of industrial chemical sludge as well as in the treatment of sludge for the food technology industry such as sugar, beer, condiments, beverages. In addition, this pump is widely used in industrial and food processing today.

Moreover, there are currently many other types of chemical dosing pumps on the market, such as Electronic Dosing Pump, Automatic Control Dosing Pump…

3. Applications of various types of Chemical Dosing Pumps

3.1/ Applications of the Piston Chemical Dosing Pump:

• The pumped substance should not be a corrosive compound or a compound containing solid particles (as corrosive substances will damage the piston seal)
• Leakage prevention requirements are not too stringent (as there will inevitably be some leakage between the piston and piston seal)

• The system requires high pressure (as the piston pump allows for pressures of several hundred kg/cm2 while other types of chemical dosing pumps can only achieve a maximum pressure of 10-15 kg/cm2)

3.2/ Applications of Hydraulic Diaphragm Metering Pumps:

• The pumped substance requires corrosion-resistant compounds and suspensions of solid particles.
• There is a high demand for leak prevention and gas leakage prevention.

• The system requires high pressure.

• The pumped substance is toxic.

3.3/ Applications of Metering Pump with Diaphragm:

• Metering Pumps with Diaphragm are used in many industries, including pumping liquids, clean water, sludge and wastewater, pumping viscous liquids, in power plants, paper mills, in the oil and gas industry, chemical industry, marine industry, etc…

4. How to choose a Chemical Dosing Pump?

When selecting a Chemical Dosing Pump, users need to understand their pumping solution as well as understand the different types of Chemical Dosing Pumps in order to choose the appropriate one.
Typically, the most important factors when choosing a Chemical Dosing Pump are the material and pump capacity. In addition, customers may choose according to the brand or price of the pump.

4.1/ Factors to consider when selecting a Chemical Dosing Pump include:

– Does the pumping solution contain solids or have viscosity?
Pumping solution: Temperature, flow rate, properties, corrosiveness, viscosity, and level

Pump voltage, pump material, pump operation, and applications for each type of pump
