XWL42.20N | 11 GPM 3000 PSI Pump Oil Sight Glass 5-Yr Warranty

XWL42.20N Industrial Pressure Washer Pump

The Annovi Reverberi XWL42.20N is a high-capacity industrial pressure washer pump
built for continuous-duty cleaning in demanding environments. Delivering
11 GPM at 3,000 PSI and running at a controlled
1,450 RPM, it provides the volume needed for large-area coverage
while maintaining the pressure required to cut through heavy contamination,
grease, and process residues. This duty point makes the XWL42.20N a strong fit
for centralized wash bays, tank wash systems, and engineered skids where uptime
and throughput matter.

• High-output design for industrial washdown and large cleaning zones.
• Balanced combination of 11 GPM flow and 3,000 PSI operating pressure.
• Low-speed 1,450 RPM operation to reduce heat and extend component life.
• 24mm solid keyed shaft compatible with belt-drive and direct-drive systems.
• Configured for continuous-duty use in harsh, wet, or chemical-prone areas.

Performance & Duty Point

The XWL42.20N is engineered for facilities that run long cycles and expect
consistent performance across multiple shifts. The pump’s 11 GPM flow rate
supports multi-gun manifolds, long hose runs, and high-volume rinse operations,
while the 3,000 PSI pressure range provides enough impact to remove heavy
soils without overspecifying the power unit. The low operating speed keeps
internal temperatures under control and limits vibration, which is critical
when the pump is mounted on skids, mezzanines, or structural platforms.

• Flow Rate: 11 GPM for high-volume washdown and flushing.
• Pressure: 3,000 PSI for aggressive cleaning and rinsing.
• Speed: 1,450 RPM for cooler, quieter, and smoother operation.
• Shaft: 24mm solid keyed shaft for flexible drive integration.
• Optimized for continuous-duty applications in industrial and municipal plants.

Pump Construction & Internal Components

The XWL42.20N is built around a heavy-duty reciprocating pump architecture
designed to handle long hours and fluctuating loads. The crankcase is cast
for rigidity and heat dissipation, while oversized bearings and a hardened
crankshaft keep moving parts in alignment over extended service intervals.
Ceramic plungers and stainless-steel valves are selected to withstand
the combined effects of pressure, temperature, and water chemistry commonly
encountered in industrial wash systems.

• Reinforced crankcase for strength, dimensional stability, and cooling.
• Ceramic plungers to resist scoring, abrasion, and thermal shock.
• Stainless steel inlet and discharge valves for reliable sealing.
• Oversized bearings to support continuous operation and high side loads.
• Engineered seal packings for long wear life under demanding conditions.

Materials & Wear Components

Wear components in the XWL42.20N are chosen for predictable service life and
straightforward replacement. The ceramic plungers maintain a smooth surface for
seal contact, helping preserve volumetric efficiency over time. Valve seats and
springs are configured for clean opening and closing at the pump’s operating
pressure, reducing turbulence and minimizing pressure loss across the head.

• Ceramic plunger surface maintains seal integrity over long duty cycles.
• Valve assemblies designed for precise opening and positive reseating.
• Seal materials selected for compatibility with water and suitable detergents.
• Component layout supports quick access during valve or seal replacement.

System Integration & Mounting

With its 24mm solid keyed shaft, the XWL42.20N is straightforward to integrate
into new builds or retrofit projects. It pairs well with electric motors and
internal combustion engines when used with properly sized pulleys or couplings.
The pump’s footprint and mounting pattern are designed to fit standard industrial
frames, skid bases, and modular wash racks, making it suitable for OEMs and
system builders who need a repeatable layout.

• 24mm keyed shaft for belt-drive or flexible coupling configurations.
• Standardized mounting pattern compatible with common baseplates and frames.
• Appropriate for wall-mounted cabinets, skid systems, and pump rooms.
• Works with typical industrial accessories: unloaders, regulators, and filters.
• Supports multi-pump banks where additional capacity is required over time.

Maintenance, Serviceability & Operation

Routine maintenance on the XWL42.20N is easy to incorporate into daily and
weekly inspection schedules. The oil sight glass and vented dipstick simplify
crankcase checks, while clearly accessible valve caps and seal packings help
shorten service windows when wear components are replaced. When installed with
proper inlet filtration and correctly sized bypass and safety devices, the pump
delivers predictable service life and controlled operating costs.

• Oil sight glass for fast visual confirmation of fluid level and condition.
• Vented dipstick for proper crankcase ventilation and oil service access.
• Field-serviceable valves and seals with minimal disassembly required.
• Adaptable to preventative maintenance programs and documented service intervals.
• Factory testing and documentation to support commissioning and troubleshooting.

Industrial Applications

The XWL42.20N is targeted at high-throughput cleaning tasks where both volume
and pressure are fully utilized. Its output supports large spray patterns,
multi-nozzle bars, and extended hose runs without sacrificing cleaning
effectiveness. This makes it a practical choice for operators who need to keep
vehicles, equipment, and process areas in serviceable condition day after day.

• Industrial tank washouts and vessel cleaning systems.
• Marine, dockside, and port equipment washdown operations.
• Municipal fleet and transit system cleaning bays.
• Manufacturing plant sanitation, floors, and production zones.
• Agricultural and livestock facility washdowns and pen cleaning.
• Contractor-grade high-flow pressure washing for large surface areas.

Why Specify the XWL42.20N

The XWL42.20N combines high flow, solid cleaning pressure, and low-speed
operation in a robust industrial package. For OEMs, integrators, and facility
managers, it offers a dependable core component for new systems or upgrades
where higher throughput and longer service life are required. When matched
with good filtration, correct plumbing, and proper safety devices, this pump
is capable of delivering years of reliable operation in demanding environments.
