Product Description

Pressure: 20~50 kgf/cm2 | Suction Volume: 7.5~18 L/Min.

Product Introduction
Key Features & Performance Advantages
  • Automatic Pressure Relief System: Automatically shifts to zero-pressure bypass mode when spray gun is closed, preventing overheating, reducing power consumption, and protecting system seals.
  • Premium Solid Ceramic Plungers: Features ultra-hard, mirror-finished ceramic plungers engineered for exceptional wear resistance, thermal stability, and extended packing seal life under heavy duty.
  • Superior Chemical & Corrosion Resistance: Highly resistant to aggressive agricultural chemicals, liquid fertilizers, and pest control agents, preventing plunger scoring and fluid leakage.
  • High-Speed 1000 RPM Capability: Precision-balanced components allow continuous operation up to 1000 RPM, delivering maximum output flow (18.2 LPM) with minimum vibration.
  • 100% Grease-Free & Self-Cooling Design: Zero-grease packing system eliminates fluid contamination, combined with fluid self-cooling mechanics to reduce friction and operating temperatures.
Standard Accessories
  • 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)
  • Heavy-Duty Suction Strainer (S-42)
  • Export Standard: Spare Packing Kit (V-Packings & Valve Packings)
Recommended Applications: Automatic-shutoff spray gun applications, high-concentration chemical spraying, continuous heavy-duty orchard operations, greenhouse fertigation, high-pressure industrial washdown, and corrosive fluid transfer.
