The ASTURO K2300 electric piston airless pump is a professional solution for applying coating materials on indoor and outdoor surfaces, suitable for light to medium building work, maintenance, technical decoration and surface finishing. The airless system atomizes the material without using compressed air directly in the spray formation process. Instead, the pump generates pressure and pushes the coating through the spray tip, allowing fast, continuous and even application compared with traditional manual methods.

The pump is suitable for coating materials, impregnating products, lacquers, enamels and wall paints for interior and exterior use, including water-based products compatible with airless spraying. The stainless steel piston and stainless steel internal components help protect the pumping unit during material flow, while the anodized aluminium line filter helps retain impurities and particles that could affect spray quality or clog the spray tip. The stable painted steel wheeled frame makes the unit easy to position on site, in workshops or in maintenance areas.

The electronic pressure control allows the operator to adapt the pump performance to the coating material, product viscosity, spray tip size and required finish. Correct pressure adjustment improves atomization quality, helps reduce excessive overspray, prevents material build-up and supports a more regular coating film on the surface. More fluid products can generally be applied at lower pressure, while thicker materials or large surfaces may require higher settings, always according to the technical instructions of the coating material and the installed spray tip.

The switch and recirculation valve are positioned for simple operation during start-up, priming, unloading and cleaning of the circuit. The recirculation valve is particularly important because it helps prepare the pump before spraying, remove air from the circuit and simplify cleaning after use. Correct cleaning is essential to maintain constant pump performance, prevent internal deposits and preserve the spray tip, filter, piston, hose and spray gun over time.

The ASTURO K2300 is suitable for professionals who need to paint walls, building surfaces, structures, panels, metal elements or components where uniform coverage and good productivity are required. In light industrial and craft applications, it can be used for maintenance work, restoration, surface protection and technical finishing. It is not a measuring instrument and does not check dimensions, heights, transmission play or geometric errors; however, in its field of use, precision depends on correct pressure adjustment, flow control, spraying distance, operator movement and correct spray tip selection.

For best practical results, it is recommended to filter the product before use, check compatibility with airless spraying, select the spray tip according to viscosity and surface type, maintain a constant distance from the workpiece and move the gun with regular overlapping passes. Spraying should not be started or stopped while remaining still on the same point, as this can cause material build-up, runs or uneven coating thickness. Pressure should be adjusted progressively, increasing it only as much as necessary to obtain a stable and uniform spray fan.

The ASTURO K2300 electric piston airless pump is therefore a practical solution for technicians, painters, maintenance operators and companies looking for a compact, robust and easy-to-transport machine for professional coating applications. The combination of stable frame, stainless steel components, electronic pressure regulation and filtered line circuit helps operators work with better control, reduce interruptions and improve the final quality of the painted surface.
