Designed by WPM (Welhome) and unveiled at major coffee expos including Melbourne (MICE) and Geneva (World of Coffee), it brings real-time pressure profiling, a rare quiet gear pump, and a circular LCD interface to a price point that used to mean spending far more. Built around a hybrid dual-boiler heating system and gear-pump precision (1–12 bar in 0.1-bar increments) with live extraction feedback, the Primus delivers flagship-level control without the flagship price. For serious home baristas who want true pressure profiling, modern extraction tools, and a tech-forward interface, it's a genuine standout in the home espresso category. 🎚️ Real-Time Pressure Profiling 🔇 Quiet Gear Pump 🔥 Hybrid Dual Boiler · 2–3 Min Heat-Up 📱 Circular LCD · Live Data 💾 20 Saved Profiles ⚫⚪ Black or Silver 💳 Finance Options Available ✅ Tariffs & Duties Included Why the Primus stands out Real-time pressure profiling — 1–12 bar in 0.1-bar increments via the tactile paddle, or programmed multi-stage profiles. Rare gear pump — a high-end component usually reserved for far pricier machines; whisper-quiet across the whole pressure range. Hybrid dual-boiler heating — 0.8 L boiler + PID thermoblock + dedicated SuperSteam thermoblock; brew and steam at once, ready in 2–3 minutes. Live extraction feedback — circular LCD in the group head shows pressure, flow, time, and temperature, plus an analog gauge. Three brewing modes — Full Manual, Semi-Auto (4-stage profile), and Auto one-touch, so it grows with your skills. 20 saved profiles — store a recipe for every bean and dial it back in any time.

Pressure profiling is the ability to vary brew pressure during extraction instead of holding a fixed 9 bar. Lower pressure during pre-infusion saturates the puck evenly; higher pressure during extraction maximizes flavor transfer. The Primus lets you control pressure from 1–12 bar in 0.1-bar increments, unlocking flavor clarity and complexity that fixed-pressure machines can't achieve. What's a gear pump and why is it special? A gear pump uses meshing gears to deliver water at precise, controllable pressure — unlike vibratory pumps (loud, fixed pressure) or rotary pumps (commercial-grade but no profiling). Gear pumps are normally found only in much more expensive machines. They're whisper-quiet across all pressure ranges and enable true 0.1-bar precision profiling. Is the Primus suitable for beginners? Yes. The Auto and Semi-Auto modes use one-touch presets, making it as easy to use as a basic espresso machine. As your skills develop, you can move into Full Manual mode for hands-on, real-time pressure control — so the machine grows with you. Can the Primus be plumbed in? Yes. It runs from its external 1.8 L rear-mounted reservoir for easy refilling, or it can be connected to direct plumbing for fewer refills — useful for higher-volume or compact cafe use.
