Model No : WL-25ASB
Product Description
Pressure: 20–50 bar (300–700 PSI) Suction Volume: 7.5–15.5 L/min (2–4.1 GPM)
Product Introduction
Key Features & Performance Advantages
  • Stainless Steel Plunger System:  Equipped with durable, corrosion-resistant stainless steel plungers designed to withstand rigorous chemical usage, ensuring long-term reliability and performance.
  • Automatic Pressure Relief (Ideal for Spray Guns):  Engineered with an air chamber-free structure and built-in automatic pressure relief, making it exceptionally suited for spray gun applications and frequent start-stop operations. It safely releases excess pressure when the trigger is released, protecting pipes and fittings from water hammer while reducing operator fatigue and mechanical wear.
  • Precision-Machined Construction:  High-rigidity design engineered for ultra-stable pressure delivery, low vibration, and minimal maintenance downtime.
Standard Accessories Included
  • Aluminum Pump Pulley 7" A2 x 19mm bore (5mm keyway)
  • Suction Hose Assembly (3/4" x 2.7m / 9ft)
  • Overflow / Bypass Hose Assembly (1/2" x 2.7m / 9ft)
  • Suction Filter (S-42)
  • Export Standard: Spare Packing Kit (V-Packings & Valve Packings)
Commercial Terms & Supply Chain: • MOQ: No MOQ required (Flexible sample & small-batch orders welcome).

Key Applications & Operational Advantages
Agricultural Crop & Orchard Spraying
Delivers a continuous and stable pressure flow to ensure fine mist atomization, enabling even chemical coverage across dense crop canopies and fruit trees.
Greenhouse Fertigation & Pest Control
Corrosion-resistant fluid path components safely handle liquid fertilizers and agricultural chemicals, making it ideal for automated or manual greenhouse spraying operations.
Livestock Farm Sanitation & Disinfection
High-pressure output enables thorough washdown and chemical fogging in poultry houses, barns, and agricultural facilities to maintain strict biosecurity standards.
Industrial & Pipeline Pressure Testing
Capable of maintaining consistent high working pressure (up to 50 kgf/cm²), suitable for hydrostatic pipe testing and heavy-duty equipment washdown.
Flexible System Configurations & Compatible Accessories
Flexible Power Matching
Easily coupled with a 0.4 - 2.0 HP electric motor for quiet greenhouse use, or a portable gasoline engine for remote field spraying without grid power.
High-Pressure Spray Hoses & Reels
Fully compatible with 8.5mm to 10mm high-pressure agricultural hoses and manual/automatic hose reels for extended spraying range.
Professional Spray Guns & Automatic Pressure Relief
Features an air chamber-free design with built-in automatic pressure relief, making it exceptionally ideal for spray gun applications. It safely discharges excess pressure when the trigger is released, protecting pipes from water hammer and reducing operator fatigue during frequent start-stop washdown tasks.
Base Frame Options
Standard Flat Base Frame provided for stationary installations. Heavy-duty Bus Frames and U-Shape Mobile Carts are also available for bulk orders (MOQ required).
