XWF26.20NV Triplex Plunger Pump | 7.0 GPM 2900 PSI

About the Annovi Reverberi XWF26.20NV Industrial Triplex Pump

High-Flow, Low-RPM Pump for Hot Water & Chemical Duty

The Annovi Reverberi XWF26.20NV is a heavy-duty horizontal triplex plunger pump engineered for
industrial-grade performance, chemical resistance, and long service life. Delivering
7.0 GPM (6.87 GPM factory rating) at 2,900 PSI while operating at a low
1,000 RPM, it is purpose-built for demanding cleaning, spraying, and wash-down applications where
uptime and durability are critical.

Designed with a forged brass manifold, ceramic plungers,
stainless steel valves, and NV (Viton) chemical-resistant seals, the XWF26.20NV
withstands hot water and aggressive detergents up to 185°F. Its 24 mm solid keyed shaft
supports belt-drive and gear-drive configurations, making it a flexible choice for industrial, agricultural, and
contractor-built systems.

How the XWF26.20NV Works

Triplex Plunger Operation & Low-RPM Design

The XWF26.20NV uses a triplex plunger design with three precision ceramic plungers that operate in
sequence to provide smooth, low-pulsation flow. This configuration reduces vibration and pressure spikes, resulting in
more stable performance at the gun or spray bar and less stress on fittings and plumbing.

Because it runs at a conservative 1,000 RPM, internal heat, friction, and mechanical wear are
significantly lower than in high-speed pumps. This low-RPM operating profile extends the life of bearings, seals,
and crank components, making the pump especially well-suited for continuous-duty industrial and agricultural systems.

The forged brass manifold resists corrosion and pressure cycling, while the
Viton (NV) seals provide compatibility with aggressive detergents, solvents, and hot-water washdown.
Together with ceramic plungers and stainless valves, these components deliver a robust, long-lasting pump platform for
demanding environments.

Benefits of the XWF26.20NV

Performance, Protection & Ease of Integration

• High flow output: 7.0 GPM supports large-scale cleaning, spraying, and rinse applications.
• Low-RPM durability: 1,000 RPM operation reduces heat, friction, and wear on internal parts.
• Chemical resistance: Viton seals handle harsh detergents, solvents, and sanitation chemistries.
• Hot water ready: rated for fluids up to 185°F for thermal-intensive cleaning.
• Heavy-duty build: brass head, ceramic plungers, and stainless valves maximize service life.
• Flexible integration: 24 mm solid keyed shaft works with belt-drive and gear-drive systems.
• Easy maintenance: oil sight glass and vented dipstick simplify daily checks.
• Long-term value: backed by a 5-year warranty and nationwide service network.

Typical Applications

Where the XWF26.20NV Excels

• Industrial washdown in food plants, factories, and chemical facilities
• Agricultural spraying and wash systems: pesticides, fertilizers, irrigation support
• Heavy equipment cleaning for construction, mining, and trucking fleets
• Marine and dock maintenance in corrosive, salt-exposed environments
• Contractor pressure washing for large-area cleaning and hot-water work

Why Choose the XWF26.20NV?

Balanced Flow, Chemical Resistance & Low-RPM Efficiency

The XWF26.20NV offers an ideal balance of high flow, moderate pressure, chemical resistance, and
low-speed efficiency. While high-RPM pumps can wear quickly under harsh conditions, this model’s
1,000 RPM operating speed keeps components cooler and reduces mechanical stress, extending service
intervals and overall life.

With Viton seals for chemical resistance, a forged brass manifold, and
ceramic plungers, it is built to thrive in tough industrial and agricultural environments where hot
water, detergents, and solvents are part of daily operation. Backed by a 5-year commercial warranty
and supported by a nationwide service network, the XWF26.20NV delivers the performance, durability, and peace of mind
professional users expect from an Annovi Reverberi industrial pump.
