AR21655 Hydraulic Pump for HYD-XW3010 | Pump Only Without Flange

AR21655 | Hydraulic Pump for HYD-XW3010 | Pump Only, Without Flange | 8.0 GPM 2200 PSI

AR21655 Hydraulic Pump for HYD-XW3010 is the genuine Annovi Reverberi replacement pump for the HYD-XW30.10 hydraulic drive unit, supplied as the bare pump without the hydraulic flange. Rated at 8.0 GPM (30 L/min) and 2200 PSI (150 bar) at 1450 RPM, this XW-series triplex plunger pump restores factory performance to an existing drive package while reusing the flange and hydraulic motor already on your equipment — the most economical way to bring a worn HYD-XW3010 system back to full output.

The AR21655 is built on AR’s 194-series industrial frame: brass head, one-piece ceramic plungers, and a high-strength steel crankshaft on oversized bearings, delivering the smooth, pulse-controlled flow that fleet washdown, agricultural, municipal, and industrial cleaning systems depend on for continuous duty.

What “Without Flange” Means

This is a repair-path SKU. Your existing HYD-XW3010 drive unit already includes the close-couple hydraulic flange that joins the pump to its motor — and that flange outlives the pump. The AR21655 ships as the pump only: transfer your flange and hydraulic motor from the worn pump to the new one, torque the hardware to spec, and the system runs exactly as it did from the factory. You avoid paying twice for drive components that are not wear items. If your flange is damaged or missing, contact WSHPWR before ordering and we will quote the flange kit alongside the pump.

Hydraulic Supply Requirements

On the complete HYD-XW3010 drive unit, the factory-matched hydraulic motor draws approximately 9.5 GPM (36 L/min) of oil at up to 2,610 PSI (180 bar) to deliver full 8 GPM / 2200 PSI water performance — roughly 11 hydraulic horsepower your machine’s auxiliary circuit must sustain continuously. Because the AR21655 reuses your existing motor, your hydraulic supply requirement does not change with this replacement. Annovi Reverberi also publishes alternative gear-motor pairings for the XW frame: a 22cc motor drawing 37 L/min (9.8 GPM) at 170 bar (2,465 PSI), or a 17cc motor drawing 27 L/min (7.1 GPM) at 231 bar (3,350 PSI). Protect whichever motor you run with a properly set upstream relief valve, keep the return line low-restriction, and maintain oil cooling for continuous-duty washing.

Heavy-Duty XW-Series Construction

The AR21655 pairs a corrosion-resistant brass pump head with stainless-steel wet-end components engineered to resist wear, cavitation, and chemical attack across years of washdown service. One-piece ceramic plungers provide superior heat dissipation and abrasion resistance, while the pressed high-strength steel crankshaft rides on oversized bearings for precise alignment and minimal friction. The die-cast aluminum crankcase includes an oil sight glass for quick level checks and drain provisions for simple scheduled service.

Installation Notes

Replacing the pump on a HYD-XW3010 unit is a straightforward shop procedure: relieve system pressure, disconnect water and hydraulic plumbing as required, unbolt the flange from the worn pump, and transfer flange and motor onto the AR21655 shaft. Confirm motor rotation direction before commissioning, keep suction plumbing short and unrestricted (flooded suction preferred), verify your unloader setting against the 2200 PSI rating, and check crankcase oil level at the sight glass before first start. Nozzle sizing should match the 8.0 GPM duty point to hold working pressure without dead-heading the unloader.

Quality Assurance & Maintenance

Every AR21655 is manufactured under Annovi Reverberi’s quality control standards and factory-tested for flow, pressure stability, and vibration before shipment. Routine upkeep is limited to pump oil changes, seal inspection, and periodic valve checks at recommended intervals — the same service schedule as the original pump, using the same AR repair kits your parts shelf may already stock. Follow winterization procedures in cold-weather storage to prevent freeze damage to the head and plumbing.
