The ASTURO K1000 230V trolley-mounted electric diaphragm airless pump is a professional airless spraying system designed for high-productivity coating applications on large surfaces, industrial environments, construction sites, maintenance work, marine applications and technical protective treatments. Airless technology atomises the coating material through the pressure generated by the pump, without mixing compressed air directly at the nozzle outlet. This allows fast coverage, good material penetration on the surface and reduced application time compared with traditional roller or brush methods.

The K1000 model is a 230V electric diaphragm pump mounted on a trolley to make movement easier on site, in workshops and in production areas. The trolley-mounted structure is particularly useful when the operator needs to work on large areas, change position frequently or reach different zones without manually carrying the complete unit. The image indicates direct suction from a 40-litre tank in the Export version, a useful feature for continuous work and for reducing interruptions caused by frequent refilling.

The pump is suitable for single- and two-component paints, water-based paints, dispersions, water-soluble products, primers, undercoats, fillers, latex, quartz washable paints, anti-rust coatings, enamels, impregnating products, zinc-rich coatings and waterproofing products. This wide compatibility makes it suitable for different coating cycles, from substrate preparation to finishing, from anti-corrosion protection to maintenance of metal surfaces, as well as technical coatings on masonry, wood, industrial structures and components exposed to weather conditions. It is a practical solution when fast coverage, work continuity and the ability to handle different materials are required.

The possibility of using two spray guns and a maximum nozzle size of 0.031", always to be evaluated according to paint viscosity and Asturo technical recommendations. Nozzle selection is essential for correct spraying: a nozzle that is too small for the material viscosity may reduce flow, create irregular application or overload the pump; a nozzle that is too large may increase material consumption and make film control more difficult. For this reason, it is advisable to check the coating product’s technical data sheet, permitted dilution, material filtration and compatibility with the selected nozzle size.

The ASTURO K1000 airless pump is intended for large surfaces, indoor and outdoor applications, spraying of dispersions, wide marine surfaces and asbestos encapsulation, where continuous and controlled product distribution is required. In construction, it can be used on walls, façades, structures, industrial buildings, technical rooms and production environments. In industrial applications, it is suitable for machinery, steel structures, metalwork, panels, containers, frames, bases and parts requiring surface protection. In preventive and corrective maintenance, it allows operators to treat already installed surfaces, reducing downtime and improving productivity.

For professional results, the substrate must be prepared carefully by removing dust, residues, grease, loose rust or unstable old coatings. The material must be mixed, filtered and prepared according to the manufacturer’s instructions. During spraying, the operator should keep a constant distance from the surface, work with regular overlapping passes and control travel speed according to nozzle flow and required coverage. Correct adjustment helps reduce defects such as runs, striping, poor coverage, material build-up, overspray and uneven film thickness.

References to precision, resolution, measurement, heights, transmission play and shape errors are not applicable to this pump as they would be to a dimensional inspection instrument. In this context, precision means regular delivery, pressure control, correct nozzle selection, stable flow and uniformity of the applied coating. Work quality depends on the combination of coating material, viscosity, pressure, nozzle, spray distance, substrate preparation and operator technique. For technicians and professionals, these parameters are essential to obtain repeatable finishing and consistent coverage over the entire surface.

After use, it is essential to clean the circuit, spray gun, filters, hose and suction system thoroughly, using a cleaning product compatible with the coating material used. Proper maintenance prevents clogging, pressure loss, premature wear and defects during subsequent spraying. The ASTURO K1000 electric diaphragm airless pump is therefore a professional solution for operators who need to handle large jobs, technical applications and demanding coating cycles with a transportable, productive system suitable for a wide range of materials.
