XWL41.21N | 10.8 GPM 3000 PSI Pump Bronze Rods Oil Dipstick

Annovi Reverberi C — 10.8 GPM, 3000 PSI Industrial Triplex Pump

High-flow pump for continuous-duty wash systems

• The Annovi Reverberi XWL41.21N is a high-flow industrial triplex plunger pump engineered for continuous-duty cleaning systems that demand both volume and pressure stability.
• Delivers 10.8 GPM at 3000 PSI, making it a strong fit for large wash bays, construction cleanup, agricultural sanitation, and commercial flatwork operations.
• Runs at a slow 1450 RPM, reducing heat, vibration, and mechanical stress to extend seal, bearing, and crankshaft life in demanding duty cycles.
• Bronze connecting rods, a forged brass head, and ceramic plungers provide a robust power section designed for long-term industrial service.
• 24 mm solid keyed shaft simplifies integration with belt-drive systems, gearboxes, or direct-coupled electric and engine-driven packages.

Construction & Materials of XWL42.15N

Industrial build for long service life

• Forged brass head and manifold deliver structural strength and resistance to pressure cycling on large wash systems.
• Bronze connecting rods provide higher fatigue resistance and load capacity than aluminum rods used in light-duty pumps.
• Solid ceramic plungers maintain dimensional stability under high pressure and temperature swings, reducing seal wear.
• Stainless steel inlet and discharge valves offer reliable sealing, corrosion resistance, and precise hydraulic timing.
• Rigid crankcase casting supports the crankshaft and bearings under continuous-duty loads with minimal deflection.
• Oversized bearings and precision-machined journals are specified to handle high side loads from belt or coupling drives.

Performance & Operation

Smooth hydraulics at high flow

• Triplex plunger layout provides smooth, low-pulsation flow, helping protect hoses, guns, and accessories from pressure spikes.
• 10.8 GPM at 3000 PSI supports multi-gun bays, rotary surface cleaners, and large-area flatwork on a single pump circuit.
• Slow 1450 RPM operation reduces fluid velocity in the pump head, which lowers erosion and internal temperature rise.
• Stable pressure output improves cleaning consistency on concrete, equipment, and vehicle surfaces, even under shifting loads.
• Low-vibration operation minimizes mechanical stress on frames, skids, and plumbing manifolds in mobile and stationary systems.

Benefits for Industrial Users

Advantages in demanding wash environments

• High throughput: 10.8 GPM flow reduces cleaning time on large surfaces, vehicles, and machinery.
• True industrial duty: Bronze rods and ceramic plungers are specified for long runtimes and frequent start/stop cycles.
• Low-RPM reliability: Cooler operation increases service intervals for seals, bearings, and oil changes.
• Service-friendly: Oil sight glass, vented dipstick, and accessible valve caps support fast routine maintenance.
• Predictable lifecycle: Built for installation in systems where uptime and planned maintenance are critical.
• Warranty confidence: 5-year commercial coverage aligns with industrial expectations for core equipment.

Typical Applications

Where the XWL41.21N is a strong fit

• Industrial vehicle wash bays handling fleets, buses, refuse trucks, and heavy equipment.
• Construction washdown for concrete tools, earthmoving equipment, and jobsite cleanup.
• Agricultural sanitation for tractors, implements, livestock trailers, and farm facilities.
• Commercial flatwork cleaning including sidewalks, parking structures, loading docks, and warehouse aprons.
• Manufacturing and industrial plant sanitation where high flow and durable hardware are required.
• Equipment rental fleets and contractor skids that demand long service life and straightforward field maintenance.

Integration & Maintenance

Design and service best practices

• Mount the pump on a rigid, level base with proper alignment to the motor or engine drive to minimize bearing load.
• Provide an oversized, well-filtered inlet supply to prevent cavitation when operating at 10.8 GPM.
• Pair with a correctly sized unloader or regulator, relief valve, and bypass return to maintain stable 3000 PSI working pressure.
• Monitor oil condition and level through the sight glass and follow a fixed schedule for oil changes and inspections.
• Inspect seals, valves, and plungers at planned intervals based on duty hours, water quality, and chemical usage.
• Document operating pressure, flow, and maintenance history to support long-term reliability in WSHPWR-grade systems.

Why Specify the XWL41.21N
