PRIMUS is WPM's latest gear-pump espresso machine — the successor to the KD-330X, engineered for the serious home barista and small café bar. A significant brewing upgrade over its predecessor: variable pressure profiling, dual PID thermoblocks, and a proper 58mm commercial group head.

Gear pump delivers smooth, quiet, precise flow. Independent supersteam thermoblock powers a 360° steam wand — no waiting between shot and milk.
