RTX85-DD 22.5 GPM 3000 PSI Pump | Direct Drive Hydraulic

RTX85-DD | Direct Drive Hydraulic Pump | 22.5 GPM Maximum Flow | Multi-Trigger Capable

RTX85-DD moves more water than anything else in Annovi Reverberi’s compact direct-drive line — 22.5 GPM (85 L/min) at up to 2200 PSI (150 bar) at 1450 RPM on the RTX 85.150 platform, with a hollow 13-tooth splined shaft for direct SAE B hydraulic motor mounting and AR’s published 32 HP rating on a 72-pound frame. And at this flow, the pump stops being a one-operator tool: 22.5 gallons a minute splits into two full commercial trigger wands, which turns one hydraulic drive into a two-person wash operation and rewrites the labor math on every job the crew touches.

Run the split: two operators at roughly 11 GPM each, both at genuine working pressure, washing opposite sides of a truck, both walls of a wash bay, or both flanks of an excavator simultaneously. Jobs finish in half the wall-clock time without a second pump, second motor, or second hydraulic circuit anywhere on the deck. Single-operator, the same RTX85-DD feeds oversized rinse nozzles, spray-bar networks, and dust-suppression manifolds that starve smaller pumps — the volume jobs are its native territory either way.

Two Triggers, One Drive — Done Correctly

Multi-trigger systems live or die on the plumbing. Feed both trigger circuits from a properly sized manifold with each line carrying an equal share, size each nozzle to its half of the flow — roughly 11 GPM per trigger wand at working pressure — and the RTX85-DD holds both operators at full performance whether one trigger is down or two. The dual 1/2″ discharge ports make the split natural: one port per trigger circuit, no tee fighting itself. The system unloader still governs the whole; set it against the combined duty point and confirm behavior with one trigger closed, because a second operator releasing the trigger should shift flow, not spike pressure. WSHPWR builds these systems regularly — call and we will spec the manifold, unloader, and nozzle pair against your layout.

Hydraulic Supply Requirements

Annovi Reverberi publishes four factory motor pairings for this platform, covering nearly every engineered circuit: gear 90cc on 37.5 GPM of oil at 1,798 PSI; piston 64cc on 26.9 GPM at 2,509 PSI; gear 44cc on 18.8 GPM at 3,611 PSI; piston 34cc on 14.5 GPM at 4,656 PSI — budget roughly 39–44 hydraulic horsepower continuously whichever fits. That wants a dedicated truck system or purpose-built power unit with reservoir, return filtration, and cooling sized for shift duty. For any other SAE B motor, target 1450 RPM via RPM ≈ 231 × hydraulic GPM ÷ displacement (in³), verify torque at working pressure, and relieve within the motor’s rating. Call WSHPWR with your circuit’s numbers and we will name the pairing.

Volume Discipline

Maximum flow concentrates the engineering at the inlet: 22.5 GPM through restricted suction cavitates, and cavitation is the one failure no build quality survives. Flooded supply, honest filtration, full-size plumbing through both 1″ inlets — non-negotiable, and doubly so on multi-trigger systems where demand steps up and down as triggers cycle. Get the inlet right and the RTX85-DD’s moderate 150-bar duty point returns the favor: seal and valve wear runs the gentlest curve in the family even at maximum water.

Direct-Drive Architecture

The hollow 13T spline engages a male-splined SAE B motor at the F56 flange — no coupler, no belt, no field alignment, no side load reaching bearings or seal packs. Motor and pump dismount independently at the flange, and the RTX85-DD shares repair kits and procedures with the entire RTX family, keeping one parts shelf behind the whole fleet.

Installation & Operation Notes

Confirm the motor spline before ordering — 13T SAE B; 14T SAE C hardware from RTD-class systems will not engage. Mount horizontally, verify rotation at commissioning, and honor the suction rules above without exception. Fit an unloader plus safety relief for the working pressure, size single-wand nozzles to the full 22.5 GPM or multi-trigger nozzles to their per-trigger share, hold 1450 RPM as the ceiling, and winterize thoroughly — the highest-flow pump in the line holds the most trapped water when the freeze comes.

Quality Assurance & Maintenance

Every RTX85-DD ships factory-tested for flow rate, pressure stability, and vibration. Service follows the shared RTX schedule — crankcase oil changes, seal inspection, in-place valve checks with common AR repair kits — on intervals the gentle 150-bar duty point stretches even at wash-bay hours.

RTX85-DD Key Features & Applications

• 22.5 GPM at 2200 PSI, 1450 RPM — the maximum-flow pump of AR’s compact direct-drive line.
• Splits into two full commercial trigger wands at ~11 GPM each — one drive, two operators, half the wall-clock time.
• Four AR-published motor pairings from 14.5 to 37.5 GPM of oil (~39–44 hydraulic HP).
• Dual discharge ports make twin-circuit plumbing natural; dual 1″ inlets feed the volume.
• Hollow 13T splined shaft direct drive on the shared RTX parts platform, ~72 lbs.
• Ideal for two-operator wash crews, fleet and bay systems, spray-bar and dust-suppression networks, hydrovac support, and maximum-volume single-wand rinse work.
