Core Performance
Pressure and Flow:
Operating Pressure: Standard version ≤ 25 bar; optional mechanical seal version supports ≤ 25 bar (customization required for high-pressure scenarios)
Flow Range: 0–200 L/min (adjustable based on rotational speed), with a maximum rotational speed of 2200 rpm
Temperature Adaptability:
Standard Seal (NBR): -25°C to 80°C;
High-Temperature-Resistant Seal (FKM): -25°C to 150°C (requires heat-resistant couplings and other accessories)
Viscosity Range: 5–1500 cSt, covering lubricating media such as diesel, gear oil, and hydraulic oil
Wear-Resistant and Low-Noise Design
Gears and Bearings: Hardened steel gears + specially coated composite sliding bearings, supporting ≤ 20 minutes of dry running (requires no radial force)
Flow Path Optimization: Short straight flow path reduces turbulence and enhances self-priming capability (startup negative pressure ≤ 0.6 bar)
Sealing System:
Standard radial shaft seal (leak-proof);
Optional mechanical seal (e.g., slip ring seal) with higher pressure resistance
Efficiency and Reliability
Volumetric Efficiency: > 90% (double circular arc tooth design reduces internal leakage)
Lifespan: > 20,000 hours under normal operating conditions (enhanced wear resistance of bearings and gears)
Environmental Friendliness: Leakage volume is only 1% of that of soft packing seals, reducing oil contamination
