About the product
The Werku WK501400 Gasoline Hydraulic Airless Sprayer is the most powerful spraying system in the Werku range — 9 HP gasoline engine, hydraulic system, and 12 LPM flow rate for industrial jobs, high-rise facades, and high-volume projects where no electrical outlet is available. Hydraulic technology ensures absolutely uniform and constant pressure regardless of the material, with a composite ABS body, anodized aluminum, and forged carbon steel. 330 mm pneumatic wheels for all-terrain job sites. Includes gun with 635 tip, 3.6 m and 15 m hoses. CE certified.
What jobs and materials is it ideal for?
- ✓ Industrial facades, warehouses, storage facilities, and buildings without access to electricity
- ✓ Work in rural areas, outdoors, or with generators where electricity is not available
- ✓ Anti-corrosion paints, roof coatings, and high-viscosity materials
- ✓ High-volume projects — up to 0.057" tip for the thickest pastes
- ✓ Acrylic paints, latex, polyurethane, lacquers, varnishes, enamels, and primers
Why choose the WK501400
- ✓ 12 LPM — the highest flow rate in the Werku range — capable of painting large-scale surfaces without interruptions; with a 635 tip, it can apply the most viscous materials on the market in a single pass
- ✓ 9 HP gasoline engine — no reliance on the electrical grid — works in any location; facades without power, warehouses under construction, remote outdoor areas; the gasoline engine does not have the limitations of a 30 m electrical cable
- ✓ Hydraulic system — absolutely uniform pressure — the hydraulic pump provides more stable and constant pressure than direct piston systems; the result is a more homogeneous finish on large surfaces
- ✓ 330 mm pneumatic wheels — all-terrain mobility — designed to move across job sites with uneven ground, dirt, gravel, and ramps; the extendable handle and large wheels facilitate transport over difficult terrain
- ✓ Complete kit ready to work — includes airless gun with 635 tip and two hoses (3.6 m + 15 m); arrive, connect, and paint without needing to buy additional accessories to start
