FD511 Hydraulic Spray Foam Machine: A Decade Forging China’s Leading Spray Foam Equipment Brand
In the field of polyurethane foam and polyurea spraying, the stability of equipment performance, construction efficiency, and adaptability directly determine project quality and overall cost. As the demand for high-end equipment in the building insulation, anti-corrosion, and waterproofing industries has increased, foreign brands long dominated the high-end market. However, China’s FDFD-511-pro" class="text-primary hover:text-primary-dark underline transition-colors" title="Dual‑gun Hydraulic Polyurea Sprayer FD‑511‑PRO" data-type="product" data-similarity="1.00">511 hydraulic spray foam insulation machine, after ten years of technological accumulation, with its core advantages of 3500 psi ultra-high working pressure, low failure rate, and high-efficiency output, has disrupted the market pattern and become a leading domestic hydraulic spraying equipment product. It has also become the preferred equipment for polyurethane foam and polyurea spraying projects. Sold to over 40 countries worldwide, with thousands of units shipped annually, it has won consistent praise from customers.

The FDFD-511-pro" class="text-primary hover:text-primary-dark underline transition-colors" title="Dual‑gun Hydraulic Polyurea Sprayer FD‑511‑PRO" data-type="product" data-similarity="1.00">511 spray foam machine offers spraying pressure comparable to the Graco HXP2, with a maximum working pressure of up to 3500 psi (approximately 24.1 MPa), far exceeding the level of ordinary industry equipment. The ample pressure allows finer atomization of materials, more uniform mixing, and seamless coating application. Whether filling polyurethane insulation layers or applying polyurea anti-corrosion layers, it effectively prevents bubbles and blisters, greatly enhancing coating adhesion and durability. This advantage is particularly notable in scenarios with strict coating quality requirements, such as large storage tanks and pipeline corrosion protection, achieving the design thickness in a single pass and overcoming the drawbacks of multiple-layer applications.
Efficient heating and ultra-long hoses can adapt to different environments—from the scorching Middle East, where the dual 10 kW heaters can operate in extreme cold conditions in North America, ensuring the necessary spraying and foaming temperature. Our oil-cooled heat dissipation system can work continuously even in the hot Middle East, reducing downtime. The system supports heated hoses up to 150 meters in length, breaking construction space limitations. Whether spraying at heights in large factories, insulating long-distance pipelines, or operating in complex sites, it can cover the work area easily without frequent equipment relocation, greatly improving construction convenience.
Relying on a stable hydraulic drive system and efficient spraying technology, the FDFD-511-pro" class="text-primary hover:text-primary-dark underline transition-colors" title="Dual‑gun Hydraulic Polyurea Sprayer FD‑511‑PRO" data-type="product" data-similarity="1.00">511 can achieve a daily spraying area of up to 2,000 square meters. For large projects with tight schedules, this efficiency can significantly shorten construction periods and reduce labor and management costs. Compared with traditional equipment, it can save more than 30% of construction time for the same workload, making it especially suitable for large-scale projects such as prefabricated building insulation, cold storage construction, and extensive exterior wall insulation.
In addition to its outstanding performance, the FDFD-511-pro" class="text-primary hover:text-primary-dark underline transition-colors" title="Dual‑gun Hydraulic Polyurea Sprayer FD‑511‑PRO" data-type="product" data-similarity="1.00">511’sappearance design is equally remarkable, reflecting the integration of industrial aesthetics and modern craftsmanship. Its sleek lines and well-organized operation interface not only enhance the machine's grade but also optimize user experience. This machine proves that practicality and beauty can coexist perfectly.
