Description

 

The WPM Primus is one of the most advanced and innovative espresso machines released in recent years — a tech-forward home and prosumer machine that brings real-time pressure profiling, a quiet gear pump, and a circular LCD interface to a price point that previously required spending $5,000+. Designed by WPM (Welhome) and unveiled at major international coffee expos including Melbourne (MICE) and Geneva (World of Coffee), the Primus has been hailed as a genuine game-changer in the home espresso category.

Built around a hybrid dual-boiler heating system, gear pump precision (1–12 bar in 0.1-bar increments), and live extraction feedback, the Primus rivals flagship machines costing significantly more — including the Decent DE1, Lelit Bianca, and La Marzocco GS3. For serious home baristas who want pressure profiling without the flagship price tag, the Primus is unmatched.

The Gear Pump — A Rare High-End Component

The star of the show is the advanced gear pump — a high-end component normally reserved for commercial machines costing $20,000 and up. This is what makes the Primus capable of true pressure profiling in 0.1-bar increments, allowing real-time pressure control as you brew. The gear pump is also whisper-quiet across the entire 1–12 bar pressure range — a stark contrast to the noisy vibration and rotary pumps found in most home machines.

Even newer Slayer Espresso models no longer feature gear pumps — and that's a feature found in machines costing five figures. The Primus brings this premium component to a fraction of the price.

WPM Primus FAQs

What is pressure profiling and why does it matter?
Pressure profiling is the ability to vary brew pressure during espresso extraction (instead of a fixed 9 bar). Lower pressure during pre-infusion saturates the puck evenly; higher pressure during extraction maximises flavour transfer. The Primus lets you control pressure from 1–12 bar in 0.1-bar increments — unlocking flavour 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 only found in machines costing $20,000+. 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 to Manual mode for full real-time pressure control. The machine grows with you from beginner to advanced barista.
Can I use my existing 58mm portafilter?
The Primus uses a proprietary portafilter design, but it's fully compatible with standard 58mm baskets and accessories. WPM has also released a bottomless (naked) portafilter for the Primus. Note: industry-standard 58mm portafilter handles will not fit — use the supplied or WPM-branded portafilter.
Can the Primus be plumbed in?
Yes. The Primus supports both the included external 1.8L water reservoir and direct plumbing connection — flexibility for home counter use or compact café installation.
Is the Primus suitable for commercial use?
According to WPM, the Primus can comfortably handle 10 cups in one go — making it suitable for compact specialty cafés, pop-up bars, and small coffee programs. For high-volume cafés (200+ cups daily), a multi-group commercial machine is recommended.
What grinder pairs best with the Primus?
A premium home grinder is essential to take advantage of the Primus's profiling capabilities. Recommended pairings: Niche Zero, Eureka Atom 75, ECM V-Titan, or Mahlkönig X54. Browse our home grinder collection.
