AR1698 | Gear Box for XW Pump Drive

AR AR1698 Gear Box Overview

High-Performance Gear Box for AR XW Series Pumps

The AR AR1698 gear box is a precision-engineered power transmission system designed by Annovi Reverberi to deliver efficient, stable, and long-lasting torque transfer for AR XW series high-pressure pumps. Built for professional and industrial cleaning systems, this gear box ensures accurate speed alignment between engine/motor and pump—improving pressure consistency, reducing vibration, and extending equipment lifespan.

Durable, Corrosion-Resistant Housing

High-Strength Cast Aluminum or Alloy Steel Construction

Constructed from high-strength cast aluminum or alloy steel, the AR1698 housing provides exceptional durability while remaining lightweight for easier installation. Its corrosion-resistant structure withstands water, detergents, and environmental exposure. The rigid design minimizes vibration and mechanical flexing, keeping internal gears perfectly aligned for smooth operation in commercial, industrial, and agricultural applications.

Precision-Machined Hardened Steel Gears

Optimized Gear Ratio for AR XW Pump Performance

Inside the AR1698 are hardened, precision-ground steel gears engineered for smooth torque conversion and efficient power transmission. Each gear engages with minimal backlash to reduce friction and noise. The optimized gear ratio converts high engine RPM into the ideal pump speed for maximum pressure output, reduced mechanical stress, and extended service life during continuous-duty operation.

Engineered Input and Output Shaft Design

Perfect Alignment for Vibration-Free Power Transfer

The precision-machined input shaft with keyway ensures secure, slip-free torque transfer from the engine or motor. The output shaft aligns directly with AR XW pumps for perfect concentric coupling. This precision fit eliminates vibration, shaft wobble, and misalignment—protecting couplers, bearings, and seals from premature wear and improving overall energy efficiency.

Sealed Oil Bath Lubrication System

Continuous Lubrication for Quiet, Long-Lasting Performance

The AR1698 features a sealed oil bath lubrication system that keeps gears and bearings continuously lubricated and cooled. The sealed housing prevents contamination from water, dirt, and detergents—ideal for pressure washing and industrial environments. Maintenance is simple: periodic oil checks and replacement are all that is required to maintain peak performance.

Fast and Accurate Installation

Precision Flanges and Standardized Bolt Patterns

Designed for easy integration, the AR1698 includes precision-machined mounting flanges and a standardized bolt pattern that matches AR XW pump housings and common engine configurations. The compact design fits portable, trailer-mounted, or stationary systems. Once installed, the gear box maintains perfect alignment without the need for adjustments.

Reliable Operation in Demanding Conditions

Stable Pressure Output and Reduced Component Wear

During operation, the AR1698 delivers stable, vibration-free performance. The optimized gear ratio keeps the pump in the ideal RPM range for consistent pressure, efficient energy use, and reduced wear. Hardened gears and sealed bearings ensure quiet, smooth performance even in continuous-use environments—ideal for professional pressure washing, industrial cleaning, and maintenance operations.

Quality Assurance and Manufacturing Standards

Precision Testing for Torque, Alignment, and Durability

Every AR1698 gear box is manufactured under strict Annovi Reverberi quality standards. Each unit undergoes dimensional inspection, dynamic balancing, and torque-load verification to ensure accurate alignment, dependable torque output, and long-term reliability in real-world conditions.

Low-Maintenance Design

Minimal Service Requirements for Long Equipment Life

Thanks to its sealed lubrication system and corrosion-resistant housing, the AR1698 requires minimal maintenance. Routine oil condition checks and periodic bolt tightening are the only recommended service steps, allowing the gear box to operate reliably for years with reduced downtime.
