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.

Different mounting mechanism than photos
Color: Light Brown, Size: 4, Color: Light Brown, Size: 4
I'm going to start off this review by stating that the mounting mechanism used on the Shelf is different than the one shown in the photo. In the photo, it shows a single bar which would have made the Shelf easier to level however, the product I received has two separate bars which means I have to be extra careful holding a level against the paper. Stencil. The reason I chose this product over different listings was because for a dollar or two more its photo showed a single bar. Now for the pros and cons: Pros: Accurate measurement. Shelf appears to be actual wood! The photos made it looks like a veneer, which it is not. Easy to install. Includes good instructions. Seems like it can hold items fairly well. Cons: The mounting hardware for drywall pretty flimsy, and I stripped out some of the drywall anchors during install. They still worked, but it was annoying to finish inserting them. The shelf doesn't sit fully flush to the wall from factory as the screws included make it protrude slightly. I can fix this with my dremel, However, This could have been solved from the factory by making the cavity slightly deeper. As mentioned above in my main detractor, it is a two bar mounting system rather than a one bar, which was shown in the photo.

Pleased overall
Color: Light Brown, Size: 4
They have an unfinished feel, and the underside screws used to hold the shelf on the poles strip out really easy. Tighten those by hand and with care. Other than that, they look great and were easy to install. Came with a full set of hardware including anchors for various wall types. Stable enough to hold small to medium sized Lego sets (don't try to put Lego Hogwarts size kits on them--not big enough). Bought 3 sets of 4 and used others as Book shelves. They work very well for novel size or paperback sized books. Just make sure you anchor them well into the wall. These will only be as good as the installation.

Nice and Inexpensive!
Color: Light Brown, Size: 4, Color: Light Brown, Size: 4
Thé shelves are good quality and easy to hang. Thé instructions do leave a bit to be desired as they misidentify which anchor to use for dry wall. I followed instructions for the first shelf and it was not very stable. I switched to the other anchors and it was great. All hardware in included. These require minimum size holes in your wall, but it is a floating shelf so be prepared to patch when you take them down.  It’s a set of 4 so a good value!
