Discover the innovative line of FMX pumps from FAMAC Motobombas, with stainless steel impeller for superior performance in demanding applications. Know more!
(Carlos Longo – FAMAC Engineering)
To deliver pumping solutions to the market that combine resistance, reliability and cutting-edge quality, FAMAC proudly presented its innovative FMX pump line. Equipped with AISI304 stainless steel rotors and AISI420 shaft, these multistage pumps were meticulously designed for demanding applications, in circumstances that require a higher degree of resistance, lower oxidation content and high mechanical quality. Due to all this, the market reception and the results obtained so far have been very positive, confirming the excellence of our innovation.
The stainless steel
Stainless steel (or simply stainless steel) is a noble alloy with undeniable resistance when compared to others such as aluminum, iron or bronze and, therefore, stands out particularly in the context of motor pumps. Furthermore, thanks to the exceptional durability of stainless steel rotors, they are almost immune to the typical wear faced by alternative materials, ensuring exceptional performance over time. Excellent, isn't it?
The architecture of FMX pumps
The architecture of the multistage pumps FMX line is given by a sequence of rotors mounted in series and separated by stages. (It is important to highlight, for those new to the subject, that at each stage, the pumped liquid gains more pressure, maintaining a constant flow rate).
Furthermore, a notable innovation in the company's motor pumps FMX line of FAMAC is the inclusion of stainless steel bushings. They not only separate, but also ensure the correct position of the rotors within each stage, improving the efficiency and durability of the system.
Rotor efficiency
The performance of the rotors is fundamental to the general performance of the motor pumps, being affected by factors such as:
- Corrosion: the rotor metal reacts with the pumped fluid, which is aggressive towards the rotor metal, resulting in material loss, surface weakening and premature failures.
- Erosion: solid particles in suspension such as sand, silt or abrasive particles can collide with the surfaces of the rotors, causing progressive wear.
- Cavitation: caused by the formation and implosion of vapor bubbles that create jets of liquid that reach the rotor surfaces, causing damage and erosion (to understand more about cavitation, read the article that we previously published here on the blog).
Furthermore, fluids containing chemical components can react with the rotor material and result in the formation of some unwanted chemical “mixture”, corrosion or deposition of materials on surfaces, negatively affecting the performance and useful life of the rotors. Likewise, fluids with extremely high or low pH can be more corrosive to certain rotor materials, increasing wear.
The temperature of the fluid can also influence its chemical and physical properties, thus affecting the performance, useful life, and wear of the rotors. Thus, fluids operating at high temperatures can accelerate chemical corrosion reactions and the rate of surface erosion.
Stainless steel rotors from the FMX line
Do you understand how the choice of rotor materials in relation to the pumped fluid is essential to avoid unwanted chemical reactions and damage to this important component?
The rotors used by FAMAC in this product are made of stainless steel (AISI 304), the same one you find in kitchen utensils, also used in hospitals and in the chemical and pharmaceutical industries. In fact, formally called austenitic steel, is known for its robust composition – with iron, chromium, nickel and, at most, 2% manganese and 1% silicon.
Furthermore, the impeller of the pumps FMX line made of FAMAC stainless steel, it has a very special feature: it is a stamped rotor. This is a manufacturing technique in which sheet metal material is shaped and cut to produce a part with a specific shape. The biggest difference is FAMAC's innovation in stamping even the rotor fins, providing incomparable lightness, quality and resistance when compared to cast iron or aluminum rotors. Did you notice the advantage?
And there's more! This FAMAC technological innovation made it possible to work with threaded shaft ends, without the use of keys, which would have been impossible to use with cast stainless steel rotors. This was another technological improvement made with our customers in mind!
Line of FMX pumps with stainless steel impeller from FAMAC
If you've come this far, you've probably noticed that the use of stainless steel in the impellers of the pumps FMX line is a direct response to all these challenges, offering impressive resistance and ensuring long life and efficient operation.
It is possible to purchase products from FMX line in single-phase, two-phase or three-phase energy. In addition to motor pumps with IP21 or IP55 motors, you can also find motor pumps with intermediate and bearing bearings. It is also possible to couple the FMX to a combustion engine, as it has a bearing developed especially for this purpose.
Also suitable for working with hot liquids (with the viton or epdm seal), as the stainless steel impeller is resistant and prevents oxidation in situations like this, the pumps FMX line meet:
- Pressure up to 221,0 mca.
- Maximum flow of 36,5 m3/ h.
- Powers from 2,0 to 15,0 hp.
You can find pump models from FMX line with different types of mechanical seals, to meet any need.
Benefits of Choosing the FMX Line
Certainly, opting for FAMAC's FMX pumps with stainless steel impeller means investing in a high-quality pumping solution that offers several benefits, such as reduced operating costs, simplified maintenance and exceptional performance even in the most challenging conditions.
Did you see how many cool features? Know that you can apply the products from FMX line in the most varied segments and applications, including:
