Mechanical manufacture


Manufacturing products of carbon steel (1040 steel), stainless steel INOX AISI 304 (4580 steel), AISI 304L (45701 steel), AISI 316 (4573 steel), AISI 316L (45703 steel) and AISI 316Ti (4574 steel) materials needed for work and easier execution of works at pumping stations and water reservoirs. The manufacturing programme consists of manufacturing water treatment plants, such as pipelines, fittings, intake gates, screw transporters, different trolleys, mud and flotate extractors, screw pumps, automatic fine screw sieves, automatic vertical bar screens, etc., We also produce covers of different dimensions and shapes for manholes of fecal sewers, water reservoirs and other objects according to the needs of the client.

Electrical engineering activities


Manufacturing electrical cabinets with the application of telemetrics - long distance surveillance and control (systems SIEMENS, SCADA etc.). They are used for alimentation of sewerage or water supply pumping stations and for controlling automatic vertical bar screens, automatic fine screw sieves, transporters and other appliances, as well as for air treatment on wastewater treatment plants. The electrical cabinets contain equipment made by renowned manufacturers of electrical equipment, such as Schrack, Schneider, Siemens, Allen Bradley etc. Within the electrical engineering activity, we perform winding of coils on the stator of electric motors of up to 50 kW.

Assembly


We are successfully performing all tasks on the field in any given moment. The employees of the company are motivated for performing assignments with high quality and they will be pleased to accept and learn to perform new assignments, according to the needs of the market. We offer assembly and dismantling of all appliances needed at the pumping stations for fecal sewerage, as well as at the drinking water reservoirs. During assembly, we use specialized tools and appliances, as well as a mobile crane if needed in case of larger and heavier constructions. We have employees trained for handling trucks above 3.5 t and mobile cranes.

Service


The service program includes service of pumps for drinking, waste and technological water (EMU, ABS, FLYGT, ELEKTROKOVINA, KSB) and other pumps, sieves and nets for extracting impurities (HUBER, GEIGER, NOGGERATH), appliances for basin aeration (RIETSCHLE - Germany, BECKER - Germany, ROBUSCCI - Italy, KUBIČEK - Slovakia). The service includes also the repairs of mechanical sets, of hardware construction, electric sets for alimentation and automatic work and for electric motor winding. In the maintenance department, repairs of reductors, compressors, diesel engines, electric motors and other mechanical equipment are performed. The service is performed by educated and quality workers, trained for working and servicing machines needed for a successful performance of the pumping stations or water reservoirs.
