TPR400-12 Rotating Nozzle | 5800 PSI Extreme Turbo
The Annovi Reverberi TPR400-12 Rotary Turbo Nozzle is a heavy-flow, high-pressure rotary nozzle built for the most demanding cleaning and excavation support applications. With a massive 12.0 nozzle size, a standard 1/4″ female inlet, and a maximum pressure rating of 5,800 PSI (400 bar), this nozzle drives very high water volume through a rotating zero-degree jet. Its 20° cone pattern and 212°F temperature rating make it a serious tool for industrial flatwork, tank and pad cleaning, and hydro-excavation/potholing when paired with appropriate equipment.
Leveraging the proven TPR400 design, the TPR400-12 combines a brass body, ceramic orifice, and balanced rotor system engineered to withstand continuous use in harsh environments. This nozzle is an excellent fit for powerful trailer skids, plant pumps, or vac-truck support setups where productivity and material removal rate are paramount.

Performance & Design Highlights
- Extreme-flow 12.0 orifice: Designed for very high-GPM professional systems, maximizing the mass of water delivered to the work zone.
- Rotating 0° jet: Concentrated stream rotates at high RPM, providing deep, chisel-like cutting for stubborn contamination and dense soils.
- Industrial-grade pressure capability: 5,800 PSI rating supports severe-duty cleaning and excavation support work.
- Hot-water ready: 212°F compatible for degreasing, softening of clays, and accelerated cleaning.
- Continuous-duty architecture: Brass and ceramic internals are engineered to maintain performance under long runtime and repeated on/off cycles.
Typical Applications
- Hydro-excavation & potholing assist: Used to loosen and cut soils, compacted aggregate, and backfill so vac-trucks can safely expose utilities, manholes, and valve boxes.
- Utility daylighting & slot trenching: Non-mechanical excavation around buried pipes and cables, reducing risk of strikes while maintaining productivity.
- Large industrial pads & containment: Cleaning heavy buildup, product residue, and tracked-in mud from big slabs and bermed areas.
- Heavy equipment & plant cleaning: Washing thick contamination from structural steel, frames, conveyors, and processing equipment.
- Extreme-duty surface preparation: Aggressive removal of stubborn coatings, scale, and weathered material prior to blasting or resurfacing.
Sizing & Compatibility Recommendations
- The 12.0 nozzle requires very high GPM; verify your pump’s GPM and PSI to avoid underperformance or overloading.
- Respect the 5,800 PSI and 212°F limits.
- The 1/4″ F connection pairs with professional lances and manifolds; for excavators, use rated adapters and plumbing.
- Not intended for light-duty or residential pressure washers—this is a severe-duty industrial accessory.
Maintenance & Best Practices
- Maintain clean supply: High-flow nozzles are sensitive to debris—service strainers and filters frequently.
- Use gradual passes when digging: In hydro-excavation, use controlled sweeps and standoff to avoid over-excavation.
- Inspect rotor and tip: Check for pattern distortion, vibration, or uneven rotation as early signs of wear.
