Description
The AR (Annovi Reverberi) RKA4G40HN is a high-performance, industrial-grade triplex plunger pump designed specifically for belt-drive or pulley-drive systems. Unlike direct-drive pumps that bolt directly to an engine, this “HN” version features a 24mm solid shaft, allowing it to be driven by a belt to reduce RPM, heat, and vibration, which significantly extends the life of the pump.
This is a “heavy hitter” in the RKA family, capable of delivering a potent 4.0 GPM at a very high 4000 PSI.
