HYD-RTXSS130.500 Stainless RTX Pump | Hydraulic Package

HYD-RTXSS130.500 | Stainless Steel UHP Hydraulic Pump | 7.9 GPM 7250 PSI | 500 Bar

HYD-RTXSS130.500 combines the two most demanding specifications in Annovi Reverberi’s compact range: ultra-high pressure and a stainless steel head. Built on AR’s UHP RTX platform, it delivers 7.9 GPM (30 L/min) at up to 7250 PSI (500 bar) at 1450 RPM with a published 38 HP (28.3 kW) rating, driven hydraulically — and its wetted head is solid stainless, corrosion-resistant through the full material section rather than coated over brass.

That pairing exists because the hardest UHP work happens in the worst water. Marine and offshore blasting strips coatings in permanent salt exposure. Desalination and RO plants run surface prep where chlorides saturate everything. Food and pharmaceutical facilities specify wetted materials before they specify pressure. Shipyard, dock, and ballast-tank work soaks equipment in brine between every job. A standard-head UHP pump in that service fights corrosion and 500-bar stress simultaneously; the HYD-RTXSS130.500 removes the corrosion front entirely and lets the frame fight one battle.

Why Stainless Matters More at 500 Bar

Corrosion and ultra-high pressure multiply each other. A corrosion pit that would be cosmetic at 2000 PSI becomes a stress riser at 7250, and a valve seat roughened by chloride attack stops sealing precisely when precise sealing matters most. Plated heads carry a barrier that erosion and cavitation microjets can breach, letting corrosion undercut from beneath — an accelerated risk at UHP velocities. The HYD-RTXSS130.500’s solid stainless head has no barrier to breach: full-section corrosion resistance at every seat, port, and sealing surface, holding UHP-grade geometry in chloride service for the life of the component. In salt-side blasting, that is the difference between a head that is a lifetime part and one that is a consumable.

Hydraulic Supply Requirements

AR’s published pairing for this platform is a piston 64cc motor supplied with 102 L/min (26.9 GPM) of oil at 203 bar (2,944 PSI) — roughly 46 hydraulic horsepower, delivered continuously from a dedicated power unit or an engineered truck system. Offshore and shipyard installations often already run hydraulic power; this pump integrates into it directly, keeping diesel and electrics away from the wet containment. For alternative motors, target 1450 RPM via RPM ≈ 231 × hydraulic GPM ÷ displacement (in³), verify torque at working pressure, cap the circuit with a protecting relief, and size reservoir, return filtration, and cooling for all-shift blasting. Call WSHPWR with your system’s numbers and we will confirm the motor spec before anything ships.

UHP System Discipline

At 500 bar the pump is one component of a safety system. Every downstream element — hose, lance, gun, nozzles, relief — carries a genuine UHP rating with margin; nothing from the 4000 PSI world enters the circuit. Inlet water is filtered rigorously, because 500-bar orifices forgive no grit, and in marine service that filtration doubles as the stainless head’s best ally against abrasive salt crystals. Operators train to UHP practice with matching PPE, seal inspections are treated as safety checks, and a pressure test follows every seal service. The HYD-RTXSS130.500 holds its side with the 366-series frame, ceramic plungers, and in-place valve access that keeps disciplined inspection easy to sustain.

Drive Architecture

The 13T spline interface couples the pump to a male-splined SAE B hydraulic motor on one centerline at the F56 flange family — no coupler, no belt, no field alignment, no side load reaching bearings or seal packs. Motor and pump separate independently at the flange for service, and the complete assembly stays compact enough for blast containers, trailer decks, and shipboard installations where space is bought in inches.

Installation & Operation Notes

Verify the motor spline before ordering — 13T SAE B class; 14T SAE C hardware will not engage. Mount horizontally, confirm rotation at commissioning, and feed the 1″ inlets flooded and filtered — cavitation at this pressure class destroys valves and plungers faster than any operating error, stainless or not. Install a certified safety relief in addition to primary regulation, pressure-test the complete assembly to UHP practice before first use, match nozzles to 7.9 GPM at working pressure, rinse the system with fresh water after salt service as good practice, hold 1450 RPM, and winterize without exception — freeze expansion in a 500-bar head is a scrapped component.

Quality Assurance & Maintenance

Every HYD-RTXSS130.500 ships factory-tested for flow, pressure stability, and vibration. Service follows AR’s RTX pattern on UHP-appropriate intervals — crankcase oil on schedule, seals inspected as safety items, valves checked through in-place access with AR repair kits — with the stainless head removing corrosion from the wear equation in the service this pump was built for.
