WPM Primus Espresso Machine — Gear Pump Pressure Profiling (KD-360X)
€1,980.00
Sales Tax Included
The WPM Primus (KD-360X) is a prosumer espresso machine built around a professional gear pump — the same pump technology found in commercial machines costing five to ten times more. It adjusts brewing pressure in 0.1-bar increments across a 1 to 12 bar range, giving you precise, repeatable control over every extraction. The triple hybrid heating system allows simultaneous brewing and steaming without any drop in pressure or temperature.
Gear Pump Pressure Profiling
Most espresso machines in this category use vibratory or rotary pumps. The Primus uses a gear pump — a mechanism typically reserved for high-end commercial equipment. The practical difference: near-silent operation, electronically controlled pressure adjustments down to 0.1 bar, and a working lifespan of 10 to 15 years with daily use. An advanced pressure sensor provides real-time feedback during extraction, displayed directly on the group head screen.
You can brew in three distinct modes. Full Manual gives you direct control via the pressure-sensitive paddle, similar to operating a lever machine but with electronic precision. Semi-Auto lets you pre-set up to 4 pressure stages and advance through them manually. Auto mode runs a fully programmable profile — up to 5 stages with set pressures and durations — for repeatable results every time. You can save up to 30 custom profiles and switch between them before each shot.
Triple Hybrid Heating System
Inside the Primus, three independent heating elements work together. A 0.8-litre copper boiler stores thermal energy for brewing. A PID-controlled thermoblock maintains group head temperature at ±1°C accuracy. A separate SuperSteam thermoblock handles steam exclusively. This architecture means you can pull a shot and steam milk at the same time — no waiting, no temperature compromise. The steam is adjustable across 7 levels and the 360° cool-touch wand provides full range of motion.
The machine is ready to brew in 3 to 5 minutes. For optimal thermal stability in the portafilter, WPM recommends a 10-minute warm-up.
Real-Time Extraction Display
A circular colour LED touchscreen sits at the top of the group head. During extraction, it shows a live graph of pressure, flow rate, temperature, and shot duration. After each shot, the extraction curve is displayed with the option to save the profile. A rotating collar around the display and the brew paddle are the main controls. No external app, phone, or tablet is needed — everything is operated directly on the machine.
Firmware updates are delivered via Wi-Fi, transferred from your smartphone to the machine.

Build and Dimensions
The Primus has a stainless steel body and weighs 21.5 kg. At 235 mm wide, 490 mm deep, and 400 mm tall, it is the most compact pressure-profiling espresso machine currently available. The 58 mm group head uses a proprietary three-ear locking design — the portafilter body is WPM-specific, but the internal baskets are standard 58 mm size. VST, IMS, and other third-party 58 mm baskets and tampers are fully compatible.
It ships with a 1.8-litre external water tank. A plumb-in option is available with the separately sold Pressure Reducer Kit. All internal water lines are food-grade Teflon (PTFE). BRITA AquaAroma Crema filters fit directly into the tank.
What's Included
The machine comes with a spouted portafilter with single and double baskets, a cleaning filter and cleaning needle, a coffee tamper, a 1.8-litre water tank with extended tube, two steam tip nozzles, and a cleaning brush. The WPM 2-in-1 Bottomless Portafilter is available separately.
