The ASTURO K30 stainless steel pneumatic piston airless pump with trolley-mounted FRL unit and painting kit is a professional high-pressure spraying system designed for intensive applications on large surfaces and industrial coating cycles. Airless technology atomises the coating material through the pressure generated by the pump, without direct compressed air mixing at the nozzle outlet, allowing fast coverage, good material deposition and higher productivity compared with traditional roller or brush methods. The trolley-mounted configuration makes the unit easier to move on site, in workshops, in production departments and along extended surfaces.

The K30 stainless steel model is suitable for painting large surfaces, shipyards, medium and large metal structures, industrial bodywork and mechanical constructions. The 30:1 compression ratio converts the supply air pressure into adequate material pressure for airless spraying, making the pump suitable for technical materials and application cycles requiring continuity, flow rate and stability. The integrated FRL unit plays an important role in compressed air preparation, as it filters, regulates and lubricates the pneumatic supply according to system requirements, contributing to regular operation and protection of internal components.

The pump is intended for use with high-solid paints, primers, adhesives, water-based paints without ethanol and epoxy resins for corrosion protection. This compatibility makes it suitable for applications where the coating must provide coverage, adhesion and long-term protection, especially on steel structures, metalwork, frames, bases, machinery, tanks, marine components, industrial vehicle body parts and surfaces exposed to weather or demanding operating conditions. In anti-corrosion applications, it is particularly important to apply the material uniformly, respecting film thickness, substrate preparation and the technical requirements specified by the coating manufacturer.

During use, correct pressure adjustment is essential to obtain stable spraying. Insufficient pressure may cause an irregular spray fan, streaking, uneven coverage or poor atomisation, especially with thicker or high-solid materials. Excessive pressure can increase overspray, material consumption, nozzle wear and stress on the circuit. For this reason, pressure should be adjusted progressively, product viscosity should be checked, compatibility with the selected nozzle should be verified and the circuit should be kept filtered and clean. Nozzle selection must be based on the type of material, required spray fan width, desired flow rate and size of the surface to be treated.

For professional results, the surface must be prepared correctly before application by removing dust, loose rust, grease, unstable old coatings and contaminants that could reduce adhesion. The material must be mixed and filtered according to the manufacturer’s technical instructions. During spraying, the operator should maintain a constant distance from the surface, use regular overlapping passes and control travel speed according to material output. When working on metal structures, complex frames, edges, welds and profiles, it is important to avoid localised build-up and ensure continuous coverage even in difficult-to-reach areas.

For this product, references to precision, measurement, resolution, heights, transmission play and shape errors should not be interpreted as they would be for a dimensional inspection instrument. The precision of the ASTURO K30 pump refers to its ability to maintain regular flow, controlled pressure, a stable spray fan and a uniform applied film. Final quality depends on the correct combination of air pressure, compression ratio, product viscosity, nozzle, spray distance, substrate preparation and operator technique. For technicians, maintenance operators and process managers, these parameters are essential to reduce rework, coverage defects and material waste.

The stainless steel configuration is particularly useful for professional applications where robustness, circuit cleanliness and compatibility with technical materials are required. The trolley-mounted frame simplifies pump transport, while the painting kit helps prepare the equipment more quickly for operation. In preventive and corrective maintenance, the K30 can be used to restore surface protection, apply anti-corrosion primers, treat metal structures and work on large installed components. In production, it can improve coating cycle efficiency, especially when large surfaces must be covered continuously.

After every use, the pump, hose, gun, filters, nozzle and material circuit must be cleaned thoroughly with cleaning products compatible with the coating applied. Dried or hardened residues can reduce flow, create spray irregularities, damage seals and compromise the quality of subsequent applications. Scheduled maintenance of the FRL unit, fittings, seals and wear parts helps keep the pump efficient over time. The ASTURO K30 stainless steel trolley-mounted pump with painting kit is therefore a professional solution for companies requiring a robust, productive pneumatic airless system suitable for technical coatings on large industrial surfaces.
