Description
The Annovi Reverberi (AR) RG21.25HN is a high-volume, industrial-grade Solid Shaft Triplex Plunger Pump.
In the world of professional pressure washing, this is considered a “Large Frame” pump. It is designed for continuous, all-day use in heavy-duty commercial environments. Because it operates at a slow 1450 RPM, it is quieter, runs cooler, and lasts significantly longer than standard direct-drive pumps.
