RTD-I-80.300N-DD | 21 GPM 4350 PSI Hydraulic Pump 1000 RPM Industrial

RTD-I-80.300N-DD | Industrial Hydraulic Drive Pump | 21 GPM 4350 PSI | Continuous Duty

RTD-I-80.300N-DD is the maximum-duty member of Annovi Reverberi’s RTD 80.300 family — the Industrial configuration of the platform, built for the service profile that separates plant equipment from truck equipment: continuous operation as the design case, not the exception. It carries the family’s defining numbers — 21 GPM (80 L/min) at up to 4350 PSI (300 bar) on the slow-turning 1000 RPM, 418-series frame, with hollow 14-tooth splined direct hydraulic drive — in the build specification AR reserves for installations that run at duty pressure hour after hour, shift after shift, as infrastructure rather than as a tool.

That distinction defines its buyers. Fixed jetting and process-cleaning stations inside plants. Industrial washdown infrastructure serving production lines. Mining and aggregate fixed-plant systems. OEM machines whose warranty math assumes the pump runs whenever the machine does. Test stands and hydro systems where the pump is a utility, like compressed air. Where the mobile RTD80.300HN-DD earns its keep on a hydrovac deck, the RTD-I-80.300N-DD is specified into the building.

What “Industrial” Means in a Duty Cycle

Most high-pressure pumps are rated honestly for hard mobile duty — full pressure while the trigger is down, recovery while the truck moves, maintenance between jobs. Continuous industrial service deletes the recovery: the pump holds duty point through entire shifts, heat soak reaches equilibrium instead of passing through it, and every wear mechanism runs at its maximum sustained rate. The Industrial configuration exists for exactly that math — the RTD-I-80.300N-DD is the version of this platform specified where the operating calendar, not the operator, sets the hours. If your application runs the pump like a utility, this is the build to quote; WSHPWR will walk the Industrial specification against your duty cycle and confirm the fit before you commit.

Hydraulic Supply Requirements

This is dedicated-power territory by definition — industrial installations feed this pump from engineered hydraulic power units. Plan roughly 70 hydraulic horsepower delivered continuously: as reference, AR’s published pairings for the adjacent RTD 100.210 run a piston 84cc motor at 314 bar and 93 L/min (24.6 GPM) — the Sunfab SCM 084W class WSHPWR supplies as the RTD companion — or a 108cc motor at 243 bar and 120 L/min. Continuous duty raises the stakes on every supporting system: reservoir volume sized for thermal mass, return filtration maintained on schedule, and cooling capacity engineered for equilibrium at full load, not peak-and-recover. Select motor displacement to hold 1000 RPM at your flow — RPM ≈ 231 × hydraulic GPM ÷ displacement (in³) — relieve within the motor’s rating, and send WSHPWR your power unit’s numbers for confirmation before the order.

Direct-Drive RTD-I-80.300N-DD Architecture

The hollow 14T splined shaft slides directly onto a male-splined SAE C hydraulic motor — no coupler, no belt, no alignment procedure, and no side load reaching bearings or seal packs. In a fixed installation that simplicity compounds: the drive that cannot drift out of alignment is the drive that never appears on the maintenance planner. Motor and pump dismount independently at the flange, so scheduled service extracts one component while the installation’s plumbing stays untouched.

Industrial 418-Series Construction

The 418 frame is AR’s heavy industrial architecture — ceramic plungers, bronze connecting rods, and crankcase geometry sized for sustained power the compact frames never see — with the 1000 RPM rated speed as the foundational durability decision: fewer plunger cycles per gallon pumped, at every hour of a service life measured in years of continuous duty. Valve access is serviceable in place, keeping inspection inside a maintenance window.

Installation & Operation Notes

Confirm the motor spline before ordering — 14T SAE C; 13T SAE B hardware will not engage. Mount horizontally, verify rotation at commissioning, and engineer the suction as permanent infrastructure: flooded supply, full-size 1-1/2″ plumbing, and filtration maintained on the plant schedule — at 21 GPM continuous, inlet condition is the single largest determinant of service life. Fit an unloader and certified safety relief rated for the working pressure, size nozzles or process orifices to the 21 GPM duty point, hold 1000 RPM without exception, and include the pump circuit in the plant’s freeze-protection plan.

Quality Assurance & Maintenance

Every RTD-I-80.300N-DD is factory-tested for flow rate, pressure stability, and vibration. Maintenance follows the industrial RTD pattern — crankcase oil, seals, and valves on intervals set by running hours — and in continuous service those intervals arrive on the calendar quickly, which is precisely where the 418 platform’s serviceable-in-place design and AR’s standard repair kits pay for themselves.

RTD-I-80.300N-DD Key Features & Applications

• 21 GPM at 4350 PSI on the 1000 RPM industrial frame — in AR’s Industrial continuous-duty configuration.
• Specified for installations that run the pump as infrastructure: shifts, not sessions.
• Hollow 14T splined shaft direct-drives from an SAE C hydraulic motor — no coupler or alignment, ever.
• Requires approximately 70 hydraulic HP continuously — engineered power units with equilibrium-rated cooling.
• Pairs with the Sunfab SCM 084W-class piston motor WSHPWR supplies for the RTD family.
• Ideal for fixed jetting and process-cleaning stations, plant washdown infrastructure, mining and aggregate fixed plant, test stands, and continuous-duty OEM systems.
