HYD-XWL50.20NB-DD | Direct Drive Hydraulic Pump | 13.2 GPM 2900 PSI | Nickel-Plated Head

HYD-XWL50.20NB-DD packs a remarkable amount of pump into 36 pounds: Annovi Reverberi’s XWL 50.20 platform delivering 13.2 GPM (50 L/min) at up to 2900 PSI (200 bar) at 1450 RPM, with AR’s published 25 HP rating, a nickel-plated brass head, and a 13-tooth splined direct-drive interface. Compare it across the aisle: the RTX-class pump carrying this same duty point weighs twice as much. For builds measured against a weight budget — slide-in skids, tandem trailers, weight-rated truck bodies, cart systems — this is RTX50-class water and pressure from the lightest frame that can produce it.

The NB head extends where that water can go. Nickel plating armors every wetted brass surface against the detergents, sanitation chemistry, salt exposure, and reclaimed-water duty that pit and de-zincify standard heads — so the HYD-XWL50.20NB-DD serves fleet detergent programs, marine and dock washdown, agricultural chemical environments, and softwash support rigs at a duty point strong enough to strip as well as rinse.

Hydraulic Supply Requirements

Annovi Reverberi’s published pairing for the XWL 50.20 platform is a gear 44cc motor drawing 71 L/min (18.8 GPM) of oil at 195 bar (2,828 PSI) — roughly 31 hydraulic horsepower delivered continuously. That wants a strong truck hydraulic system, a high-flow machine circuit, or a dedicated power unit; standard compact auxiliaries will run the pump at reduced output. For alternative motors, size displacement to reach 1450 RPM via RPM ≈ 231 × hydraulic GPM ÷ displacement (in³), verify torque at working pressure, cap the circuit with a relief protecting the motor, and provide return filtration and oil cooling for continuous duty. Call WSHPWR with your circuit’s flow and pressure and we will confirm the pairing before you order.

Power Density Is the Spec

Every pound on a mobile wash system is paid for twice — once in payload and once in the structure that carries it. At 25 published horsepower from a 36-pound frame, the HYD-XWL50.20NB-DD delivers among the best power-to-weight in AR’s entire hydraulic range: the practical difference between a one-technician slide-in and a forklift install, between a tandem trailer that scales legal and one that doesn’t, between fitting the wash system in the tool compartment and giving up the deck. Operations that need this duty point with maximum-hours durability can step to the RTX-class frame at twice the mass; operations that need the weight back choose this pump. WSHPWR stocks both sides of that trade.

Why the Nickel-Plated Head

Chemistry finds brass. Detergent programs, sanitizer cycles, salt air, and reclaimed water all attack standard heads at the valve seats and sealing surfaces — slowly, then as a cascade of valve service and pressure fade. Nickel plating lays a hard, chemically resistant barrier over every wetted surface of the HYD-XWL50.20NB-DD, extending head and seat life dramatically in exactly the duty its buyers run. If the system will ever inject soap, softwash mix, or sanitation chemistry, the NB head is cheap insurance bought once.

Direct-Drive Architecture

The 13-tooth splined interface couples the pump to its hydraulic motor on one centerline — no belts, pulleys, guards, or field alignment, minimal side loading on bearings and seal packs, and output independent of host engine speed. Motor and pump separate independently at the interface when service calls, keeping the repair path simple for fleet shops.

Installation & Operation Notes

Confirm the spline and mounting interface against your motor before ordering. Mount horizontally, verify rotation at commissioning, and engineer the suction path seriously: 13.2 GPM through the 3/4″ inlet demands flooded, filtered, unrestricted plumbing — buffer-tank feed is standard practice at this flow. Fit an unloader against working pressure plus appropriate relief protection, size nozzles to the 13.2 GPM duty point, flush with clean water after chemical sessions to maximize the nickel head’s service life, hold 1450 RPM, and winterize before cold-weather storage.

Quality Assurance & Maintenance

Every HYD-XWL50.20NB-DD ships factory-tested for flow rate, pressure stability, and vibration. Maintenance follows AR’s standard schedule — crankcase oil changes, seal inspection, periodic valve checks with AR repair kits — with the nickel head stretching valve-seat intervals in chemical-heavy duty.
