XWAM8G29N-SX | 8 GPM 2900 PSI Pump 1750 RPM Left Hand Shaft

XWAM8G29N-SX Triplex Pump

Reverse-Rotation Pump for Heavy-Duty Cleaning Systems

The Annovi Reverberi XWAM8G29N-SX is a specialty industrial triplex plunger pump designed
specifically for reverse-rotation drive systems. Delivering 8.0 GPM at 2,900 PSI, it provides
high flow with controlled pressure, making it ideal for large-scale commercial and industrial cleaning where
productivity and reliability are critical.

• Engineered for counterclockwise belt- and pulley-drive configurations.
• High-flow, moderate-pressure output for multi-gun and wide-area cleaning.
• Built for aggressive environments with heat, chemicals, and long duty cycles.

How the XWAM8G29N-SX Works

Triplex Plunger & Reverse-Rotation Design

The XWAM8G29N-SX uses a triplex plunger system, where three ceramic plungers operate in sequence
to generate a smooth, low-pulsation flow of 8.0 GPM at 2,900 PSI. This design reduces vibration,
protects downstream components, and provides consistent pressure at the gun or spray bar.

Its 24 mm solid left-hand shaft is built for reverse-rotation drive systems, commonly used in
counterclockwise belt-drive layouts, compact trailer mounts, and custom skid builds. By matching the pump’s
rotation to the drive system, operators avoid extra idlers, cross-over belts, or complex packaging workarounds.

• Triplex plunger mechanism minimizes pulsation and vibration.
• Reverse-rotation shaft integrates directly with counterclockwise drive systems.
• Ceramic plungers and Viton seals handle heat and aggressive wash chemistries.
• Forged brass manifold is designed for repeated pressure cycles and harsh environments.

Benefits

Why This Pump Works Well in Reverse-Drive Rigs

• High-volume output: 8.0 GPM supports multi-gun operation and large-surface cleaning.
• Controlled pressure: 2,900 PSI delivers strong cleaning force without excessive surface damage.
• Reverse-rotation ready: left-hand shaft eliminates the need for workarounds on counterclockwise drives.
• Durable internals: ceramic plungers and Viton seals extend service life in hot, chemical-rich environments.
• Reliable manifold: forged brass head resists cracking, corrosion, and pressure fatigue.
• Easy maintenance: sight glass and vented dipstick simplify daily oil checks and service routines.
• Commercial support: factory testing and a 5-year warranty reduce downtime risk.

Typical Applications

Where the XWAM8G29N-SX Excels

• Parking structure and garage washdown, including ramps and decks.
• Theme parks, stadiums, and public facility cleaning and maintenance.
• Contractor-built wash trailers and mobile cleaning rigs using reverse-drive layouts.
• Meat, poultry, and USDA-orientated sanitation systems (with compatible accessories and chemistries).
• Oilfield and mining equipment cleaning in harsh, remote environments.
• Industrial fleet wash bays for trucks, buses, and heavy machinery.
• Custom reverse-drive cleaning systems where shaft orientation is critical.

Why Choose the XWAM8G29N-SX?

High Flow, Reverse Rotation & Long-Term Reliability

The XWAM8G29N-SX is built for operators who need a high-flow, reverse-rotation pump that can endure
long duty cycles, frequent use, and aggressive cleaning environments. Unlike standard clockwise pumps, its
left-hand shaft is designed from the ground up for reverse-drive applications, reducing complexity in the overall
system design.

• Ideal replacement or upgrade for reverse-rotation trailer and skid systems.
• Reduces design compromises in tight engine, motor, or belt layouts.
• Balances strong performance (8.0 GPM, 2,900 PSI) with proven AR durability.
• Supported by a 5-year commercial warranty and nationwide AR service network.

For large-scale industrial and commercial cleaning where reverse-rotation drives are required, the XWAM8G29N-SX
delivers the flow, pressure, and durability needed to keep rigs productive and profitable.
