As a result of our concern to improve our performance and investing much of our resources in research, we have adapted and modernized our facilities to meet a wide variety of demands. Now our machining area is controlled through a digital computerized control system.
Thanks to this modernization, we have better production control, ensuring our customers greater flexibility and even shorter delivery times. In addition, spare parts and accessories can be shipped within 24 hours.
It is made up of the suction and discharge nozzles and the intermediate sections, which are made of steel or cast aluminum, depending on the model. The standard position of the nozzles is vertical, although they can be modified depending on needs. The nozzles and intermediate sections are fitted and assembled with steel bars. The tightness of the components is achieved through the use of a sealing compound and in certain cases by an O-ring. The number of compression stages varies depending on the pressure required with a maximum of 10 in small machines and 7 in large machines.
It is made up of a steel shaft and a set of impellers with spacers fixed by keys. The impellers are made of cast aluminum alloy or in certain applications, riveted sheet metal. They are statically balanced. The rotor is dynamically balanced to ensure vibrations less than 4.5 mm/s when rotating. There is a wide range of radial and curved impellers in order to meet different requirements.
The bearings are mounted in independent cast iron bearings. The bearings are fixed to the nozzles, allowing easy accessibility in case of maintenance without the need to dismantle other parts. The bearings constitute the only point of contact between the rotor and the stator of the machine. The tightness of the bearings is ensured by graphite braids or in large machines by 4-section carbon rings joined by a stainless steel spring. The sealing by carbon rings reduces leaks to the minimum possible. In case of working with dangerous gases, tightness is ensured by double mechanical sealing. It is also possible to achieve sealing by injecting gas between the carbon rings. For machines up to 5000 m3/h, lubrication is carried out with grease and for larger machines with a constant oil level, allowing maintenance time to be extended, ensuring impeccable operation.
