AR Annovi Reverberi RMV25G30D-EZ Replacement Horizontal Plunger Pump – 3000 PSI, 2.5 GPM, EZ Start, Aluminum

Product overview

The AR Annovi Reverberi RMV25G30D-EZ is a horizontal plunger pump designed for demanding cleaning tasks. It delivers up to 3,000 psi and 2.5 GPM through a direct-drive setup that can pair with gasoline engines in the 4–7 HP range. The pump body is die-cast aluminum, paired with a hollow shaft, a brass head, and hardened steel pistons, creating a sturdy core that supports frequent use and long-lasting performance.

Key design details support efficiency and reliability. A built-in pressure control valve helps maintain a steady flow, while a chemical injection system enables controlled additive delivery without external adapters. The EZ Start valve reduces starting effort and helps prevent sudden pressure surges as the unit engages. The three-piston alternating design is optimized for steady cleaning cycles, and a double gasket sealing system minimizes leaks in typical work environments.

Versatility and compatibility are at the core of this pump. It fits 3/4" shaft engines and standard mounting patterns, with a 3/4" inlet and 22mm x 14M discharge. Direct coupling to a wide range of motors is supported, making it suitable for many pressure-washer configurations. The lightweight, die-cast aluminum construction simplifies handling and storage on job sites or in repair shops.

Practical use scenarios include patio and driveway upkeep, deck scrubbing, vehicle washing, and exterior surface cleaning. The unit is designed for reliable performance under typical outdoor conditions, with a maximum operating temperature of 140°F. For maintenance, keep seals in good condition, and ensure detergent lines are clean and properly connected when using chemical injectors.
