The RSV 4G40 Annovi Reverberi hollow shaft pump is designed for high-performance cleaning systems and direct engine-driven setups. Operating at 3400 RPM, it features a 1" hollow shaft and comes equipped with an integrated unloader valve and chemical injector, making it ideal for petrol-driven pressure washers.

This pump delivers a powerful 15.1 litres per minute at 275 Bar (4000 PSI), requiring 11 HP to run at full output. Its 3-piston alternating volumetric design, driven by a crank-connecting rod mechanism, ensures smooth performance and long-term durability.

The die-cast aluminium alloy pump body includes an oil drain outlet, with a matching rear cover for added rigidity. The pressed high-strength steel shaft, oversized friction bearings, and bronze connecting rods enhance strength and reduce wear.

Internally, the pump uses ceramic-coated stainless steel pistons, a pressed brass pump head, and a double gasket sealing system for optimum sealing and resistance under pressure. The delivery valves are inspectable, and the built-in regulating valve allows for precise control during use.

Supplied with a 1" SAE J609a flange, it’s ready for direct mounting to most common petrol engines.
