Description
Unique Product Advantages
- Exceptional Extraction Pressure: The pump generates a formidable water pressure of 220–290 PSI (1500–2000 KPa). This specific pressure range is a unique competitive advantage, as it is precisely calibrated to meet the rigorous demands of professional espresso extraction.
- Industrial-Grade Durability: Validated through exhaustive testing, the unit supports a lifespan of over 100,000 cycles. This longevity is measured under a demanding duty cycle of 20 seconds active (ON) and 40 seconds rest (OFF), ensuring reliability in high-frequency commercial environments.
- Whisper-Quiet Operation: Despite its high-pressure output, the device maintains a low acoustic profile of less than 55dB at a distance of 30cm. This makes it ideally suited for premium home appliances and quiet office settings.
- Consistent Power Efficiency: Across all supported voltage variants (from 3.7V to 12V), the pump maintains a stable power consumption of 3.6W. This consistency allows for predictable energy management in battery-powered or mains-connected designs.
- Robust Self-Priming Capabilities: The engineering design allows for a suction head of 1.5–3 metres and a pump head of 3–5 metres. This ensures the pump can effectively draw and lift water across significant distances without external priming.
