AR RKA4G40GR Gear Drive Pressure Washer Pump – 4.0 GPM @ 4000 PSI

Part Number: RKA4G40GR
Category: Pressure Washer Pumps
Type: Gear-Drive Triplex Pump – AR RKA4G40GR, 4.0 GPM @ 4000 PSI

The AR RKA4G40GR Gear Drive Pressure Washer Pump is a commercial-grade triplex plunger pump designed for gear-reduced pressure washer systems that demand high pressure, durability, and long service life. Delivering 4.0 GPM at up to 4000 PSI, this pump is ideal for professional and industrial applications where consistent performance and reduced pump wear are critical. Built by Annovi Reverberi (AR) with heavy-duty internals, the RKA4G40GR pairs perfectly with gear-reduction drives to provide smoother operation, lower operating speeds, and extended component life compared to standard direct-drive setups.

This model is commonly used in engine-driven commercial machines where reliability, torque handling, and continuous-duty capability are required.
