The Asturo K300 electric airless diaphragm pump 230V, item 0730006, is a professional pump for airless application of liquid materials, designed for medium-small jobs and non-heavy-duty use in craft, light industrial, building and agricultural environments. The image shows a compact configuration with fixed frame, motor-pump unit, upper hopper and product suction hose, making it suitable when a practical, stable and easily positioned system is required in the work area.

The airless principle allows the material to be sprayed without using compressed air as the main atomising medium. The pump pressurises the material and sends it through a high-pressure hose and dedicated spray gun to the spray tip. This allows an even distribution of the product on flat surfaces, structures, panels, wooden elements, light metalwork, internal walls and components requiring regular and continuous coverage.

The version shown is described as “pump only”, therefore it must be completed with compatible accessories such as high-pressure hose, airless spray gun, filter, tip holder and spray tip selected according to the material to be applied. Choosing the correct spray tip is essential because it affects flow rate, spray fan width, applied thickness and finishing quality. More fluid materials generally require smaller orifices, while denser products, base coats, primers or fillers require an adequate tip size and compatibility with the pump must always be checked.

The Asturo K300 Airless pump is suitable for synthetic acrylic and water-based paints, one-component and two-component enamels, polyurethanes, impregnating products, dispersions, emulsion paints, washable paints, epoxies, base coats, primers, anti-rust coatings, fillers for crack repair in building restoration, liquid resin injection and agricultural pesticide products. This versatility makes it suitable for different departments and sectors, from interior painting to structural maintenance, from corrosion protection to finishing wooden or metal products.

In joinery it can be used for impregnating products, base coats, primers and protective materials on panels, frames, structural elements and wooden components. In metalwork it is useful for applying anti-rust coatings, primers and enamels on metal structures, supports, frames and painted parts. In building applications it is suitable for emulsion paints, washable paints, dispersions and restoration products, while in agriculture it can be used with liquid pesticide products, always respecting chemical compatibility and the safety procedures required by the material manufacturer.

To obtain a correct application, it is important to filter the material before use, check viscosity, select the correct spray tip and maintain a constant distance from the surface. The spray gun must be moved regularly, with parallel passes and uniform overlap, avoiding material build-up at turning points. Pressure should be adjusted to obtain a full and stable spray fan, without side streaks, excessive overspray or poor coverage.

During operation, it is advisable to perform a preliminary test on a sample surface in order to check fan pattern, deposited quantity, uniformity and material compatibility. If the spray pattern is irregular, it may be necessary to correct filtration, dilution according to the technical data sheet, spray tip selection or working pressure. Moving too quickly may cause insufficient coverage, while moving too slowly may cause runs, excessive thickness or uneven drying times.

Pump maintenance is essential to preserve delivery consistency, diaphragm life and system reliability. At the end of the job, the circuit, suction line, filters, spray gun and tip must be thoroughly cleaned with a cleaning product compatible with the material used. Dry or partially cured residues can obstruct passages, reduce flow rate, affect spray quality and increase wear on internal components.

The Asturo K300 electric airless diaphragm pump 230V is therefore a practical solution for professionals looking for a compact machine for medium-small applications with liquid products. It is suitable for painters, joinery workshops, metalwork shops, building contractors, maintenance technicians and agricultural operators who need a stable, versatile airless system that can be completed with spraying accessories suited to the specific job.
