Stable Water Supply and Boost: As the core power component of the coffee machine, it continuously and stably delivers fresh water from the water tank to the extraction system, accurately establishing standard extraction water pressure to ensure consistent water flow. This prevents fluctuations in water pressure that could affect coffee extraction and is suitable for various types of Italian coffee making. Precise Pressure-Controlled Extraction: The water pressure can be flexibly adjusted to achieve dual modes of low-pressure pre-infusion and high-pressure standard extraction, allowing the coffee grounds to fully absorb water and expand, evenly releasing flavor compounds, enhancing the coffee's taste and crema thickness. Rapid Start and Stop Water Delivery: Water delivery starts instantly when powered on and stops immediately when powered off, with no delay or residual water. This ensures precise control of water output and extraction time, avoiding over-extraction or under-extraction, so that each cup of coffee maintains consistent brewing time and flavor. Adaptable for Multiple Water Delivery Scenarios: It can meet the high-pressure water supply needs for espresso extraction while also supporting hot water output and steam-assisted water supply, accommodating functions such as American coffee, espresso, and milk frothing, fully suitable for both home and commercial coffee machines.
