WPM introduces the PRIMUS with real-time Pressure Profiling technology - a feature previously exclusive to professional machines. The advanced pressure sensor displays precise readings instantly on a color LED screen, giving you complete extraction control. The professional Gear Pump delivers quiet performance and exceptional stability, while the Triple Hybrid Heating System ensures ±1°C thermal accuracy. PRIMUS transforms home espresso into a customizable professional experience.

Pressure Profiling

PRIMUS features advanced real-time pressure profiling technology, a feature previously exclusive to extremely expensive professional machines. The precision pressure sensor allows you to monitor and adjust pressure instantly during extraction on the color LED display. You can choose from pre-programmed pressure profiles (classic, pre-infusion, low, very low) or create and save your own custom profiles. This technology gives you the ability to extract complex and varied flavors from the same coffee beans, and control sweetness, bitterness, and acidity with surgical precision. Whether you're using light roast Ethiopian or dark Brazilian coffee, you can customize the perfect pressure profile for each type.

Professional Gear Pump

Unlike the noisy vibratory pumps in traditional machines, PRIMUS uses a professional gear pump that delivers exceptionally quiet performance. This pump operates almost silently. The gear pump provides completely stable and smooth pressure without any pulsing or vibration, resulting in more even extraction and cleaner, clearer flavor. It also offers a wide pressure range from 2 to 11+ bar, essential for effective pressure profiling. The gear pump features a long lifespan of 10-15 years with daily use, compared to 2-3 years for vibratory pumps, making it a true long-term investment.

Triple Hybrid Heating System

WPM has innovated a unique heating system combining three components working in perfect harmony: a 0.8L copper boiler providing excellent thermal stability and large energy storage, a smart thermoblock with PID control ensuring ±1°C thermal accuracy and rapid heating, and a SuperSteam thermoblock dedicated exclusively to producing powerful and continuous steam. This advanced system allows you to brew espresso and steam milk simultaneously without any impact on either function's performance. No waiting between shots, no cooling flush needed, and no concern about steam temperature drops. A smooth professional workflow just like commercial cafes.

Precise Temperature Control

PRIMUS offers a wide adjustable temperature range from 70 to 98°C, allowing you to set the optimal temperature according to roast type. Light roast coffee needs higher temperature (92-96°C) to extract bright and complex flavors, while dark roast needs lower temperature (85-88°C) to reduce bitterness. Thanks to advanced PID technology, the machine maintains the target temperature with ±1°C accuracy without any fluctuation, ensuring perfect repeatability and consistent extraction every time. This level of thermal control eliminates the need for "temperature surfing" and guarantees professional results in every shot.

Professional 58mm Group Head

PRIMUS uses a professional 58mm metal group head, the industry standard used in commercial cafes worldwide. This size means complete compatibility with thousands of professional accessories and tools available in the market, from specialized filter baskets to distribution tools and various tampers. The heavy metal construction provides excellent heat retention, ensuring stable extraction temperature. The skills you develop on PRIMUS transfer directly to commercial equipment, making it ideal for baristas training at home or practicing competition recipes.

Advanced Steam System

PRIMUS features a 360-degree rotating steam wand with a professional dual-hole tip, providing complete freedom in pitcher positioning and creating silky microfoam perfect for latte art. The standout feature is steam power control across 7 adjustable levels, allowing you to adjust power according to pitcher size and your technique. Low levels (1-2) are ideal for small quantities and provide precise control for beginners, medium levels (3-5) are excellent for standard latte size, and high levels (6-7) provide professional power for large pitchers or multiple preparations. The dedicated SuperSteam thermoblock ensures powerful and continuous steam without waiting or performance degradation.

Smart Color LED Display

The clear color LED display shows all vital information in real-time: current pressure during extraction, set and actual temperature, pressure profile in use, and operating status. The screen is easy to read in all lighting conditions and provides immediate visual feedback helping you learn and improve quickly. You can monitor how grinding and dosing adjustments affect pressure directly, turning the brewing process into an interactive learning experience. The intuitive interface makes navigating between different settings and profiles easy and fast.

Complete and Comprehensive Package

PRIMUS comes with all necessary accessories to start immediately: professional 58mm portafilter with ergonomic handle, single-shot (7-10g) and double-shot (14-18g) precision filter baskets, properly sized coffee tamper, backflush cleaning basket, steam wand cleaning needle, and group head maintenance brush. The removable 1.8L water reservoir reduces the need for frequent refilling and facilitates cleaning. All these high-quality accessories valued at over $200 are included with the machine, saving you separate purchase costs and ensuring perfect compatibility.

*The machine includes a free portafilter. If you would like to use an additional portafilter, please ensure it is designated for WPM machines in both type and size.
