XWL50.20HNB-DD | 13 GPM 3000 PSI Direct Drive Nickel Plated Head

XWL50.20HNB-DD High-Capacity Industrial Pump

The Annovi Reverberi XWL50.20HNB-DD is a high-capacity, direct-drive industrial pump
designed for continuous-duty service where both flow and pressure are fully utilized.
Delivering 13.0 GPM at 3,000 PSI at a controlled 1,450 RPM,
it provides the volume needed for large-area cleaning while maintaining the pressure
required for aggressive washdown, degreasing, and process support in demanding plants
and wash bays.

• 13.0 GPM output to support multi-gun manifolds and large surface tools.
• 3,000 PSI working pressure for heavy cleaning and production washdown.
• Slow-speed 1,450 RPM operation to limit heat, vibration, and wear.
• Direct-drive configuration for compact packages and efficient power transfer.
• Designed for continuous-duty operation in industrial and commercial systems.

XWL50.20HNB-DD Hydraulic Performance & Duty Point

The XWL50.20HNB-DD is sized for systems where throughput and turnaround time are
critical. The 13 GPM duty point supports long hose runs, twin-gun operation, and
high-volume surface cleaners without starving downstream components. The 3,000 PSI
rating provides strong jet energy for removing grease, road film, and process residues
on equipment, vehicles, and production areas, while the low operating speed helps keep
the hydraulic circuit stable and predictable.

• High flow for rapid coverage of pads, bays, vehicles, and equipment.
• Consistent pressure delivery across long runs and multiple outlets.
• Reduced pulsation compared to lighter-duty designs at similar flow.
• Balanced operating point for electric or engine-driven power units.
• Practical duty range for centralized washdown and plant cleaning systems.

Nickel-Plated Manifold & Corrosion Protection

A key feature of the XWL50.20HNB-DD is its nickel-plated forged brass manifold. The
plating protects wetted surfaces from pitting, scaling, and chemical attack, helping
maintain internal port geometry and sealing surfaces over long service intervals.
This is especially important in installations that see aggressive detergents,
mineral-laden water, or high humidity.

• Nickel-plated forged brass head for enhanced corrosion resistance.
• Improved resistance to oxidation, mineral scaling, and surface degradation.
• Stable manifold geometry supports consistent pressure and flow over time.
• Suitable for moisture-rich, chemical-heavy, or outdoor wash environments.
• Extended manifold life relative to uncoated brass configurations.

Wet-End Materials & Components

All major wet-end components XWL50.20HNB-DD are selected for durability at high pressure. Solid
ceramic plungers provide a hard sealing surface that resists abrasion and thermal
shock, while stainless steel valves maintain accurate seating under repeated
cycling. High-temperature elastomers are used in the seal and packing sets to
tolerate pressure, temperature variation, and compatible detergents.

• Solid ceramic plungers for long wear life and stable sealing surfaces.
• Stainless steel valves for precise flow control and cavitation resistance.
• High-temperature Buna-N style seals for dependable leak protection.
• Wetted materials chosen for demanding washdown and industrial service.
• Serviceable design that accepts standard AR replacement kits.

Triplex Direct-Drive Powertrain

The XWL50.20HNB-DD uses a triplex plunger configuration to convert rotational power
into high-pressure flow with low pulsation. Three plungers operate in sequence,
driven by a precision-ground crankshaft housed in a rigid, die-cast aluminum
crankcase. The direct-drive layout removes the need for belts and pulleys, reducing
mechanical losses and eliminating belt-related adjustments from the maintenance plan.

• Triplex plunger arrangement for smooth, low-pulsation hydraulic output.
• Direct connection to the power source for efficient torque transfer.
• Reduced component count versus belt-drive designs.
• Compact assembly that simplifies guarding and enclosure design.
• Stable operation at 1,450 RPM for extended run times.

Crankcase, Bearings & Lubrication

The die-cast aluminum crankcase is machined for alignment and strength, with
external fins to support heat dissipation. Oversized bearings carry radial and
thrust loads, and an oil bath lubrication system keeps the crankshaft, rods, and
bearings continuously coated. This combination supports long service intervals in
continuous-duty fleets and plant systems.

• Die-cast aluminum crankcase with cooling fins to manage operating temperature.
• Precision-ground crankshaft for smooth, quiet rotation.
• Oversized bearings sized for continuous-duty industrial workloads.
• Oil bath lubrication system to reduce friction and wear.
• Crankcase layout designed for long-term mechanical stability.

Maintenance, Monitoring & Service Access

The XWL50.20HNB-DD is configured to make routine maintenance straightforward for
in-house technicians. An integrated oil sight glass allows quick confirmation of
oil level and condition, while clearly positioned fill and drain points support
clean oil changes. Large valve caps allow direct access to valve assemblies, and
standard AR seal and valve kits help keep turnaround times predictable.

• Oil sight glass for fast visual checks of crankcase level and oil appearance.
• Accessible fill and drain ports for efficient oil service.
• Large valve caps for straightforward valve inspection and replacement.
• Field-serviceable wet end with commonly available service kits.
• Factory testing for pressure, flow, and sealing integrity prior to shipment.

Integration & Typical Applications

With its compact frame and direct-drive layout, the XWL50.20HNB-DD integrates
cleanly into new builds or retrofit projects. It is suited to skid-mounted systems,
pump rooms, and mobile equipment where high flow and reliable pressure are needed
on every shift. The pump’s output and materials align well with industrial washdown,
fleet cleaning, and general plant sanitation.

• High-flow industrial cleaning and degreasing skids.
• Centralized sanitation and washdown manifolds.
• Portable and stationary wash units in plants and yards.
• Mobile cleaning trailers and fleet wash systems.
• Equipment, agricultural, and construction washdown operations.
