CWX4G25N 4.0 GPM 2500 PSI Plunger Pump | CWX Series 1750 RPM
CWX4G25N – AR CWX Series Triplex Plunger Pump
The AR CWX4G25N is a high-performance industrial triplex plunger pump engineered for
applications that demand consistent water flow, stable pressure, and long-term durability under
continuous operation. Delivering 4.0 GPM at 2,500 PSI and 1,750 RPM, this CWX Series
model is built for professionals who need reliable output, smooth operation, and low maintenance in
commercial and industrial environments such as car washes, manufacturing plants, agricultural equipment
cleaning, and industrial maintenance systems.
Key Features & Design Benefits of CWX4G25N
Hydraulic Performance
- Rated output: 4.0 gallons per minute at 2,500 PSI for effective cleaning and process
rinsing in demanding applications. - 1,750 RPM operating speed: Balances pressure performance and efficiency while
minimizing heat buildup, vibration, and noise. - Triplex plunger design: Balanced crankshaft motion across three plungers reduces
mechanical wear and vibration, providing quiet, stable operation at high pressure. - Steady pressure: Smooth discharge helps protect downstream accessories—hoses, guns,
nozzles, and regulators—from pressure spikes and fatigue.
Construction & Internal Components
- Forged brass manifold: Offers exceptional corrosion resistance and dimensional
stability, extending service life in harsh, detergent-rich or hard-water environments. - Die-cast aluminum crankcase: Provides strength and rigidity while keeping overall
weight manageable for easier handling and installation. - Oil-bath lubrication: Internal bath continuously coats moving components to reduce
friction, dissipate heat, and prevent premature bearing wear; a sight glass and vented oil cap
simplify level checks and service. - Ceramic plungers: Precision-ground and polished solid ceramic plungers maximize
smoothness and wear resistance for tight sealing and efficient flow on every stroke. - Stainless-steel valves: High-grade valves, springs, and retainers are designed for
optimal sealing performance and resistance to pressure cycling fatigue in long-duty operation. - Tapered roller bearings: Oversized bearings support the forged steel crankshaft,
distributing load evenly to extend component life and maintain alignment at 1,750 RPM. - Optimized oil circulation: Internal passages promote uniform oil distribution to
bearings and connecting rods, preventing localized heat spots and supporting smooth mechanical motion.
Serviceability & Integration
- Easy service access: CWX Series layout provides accessible valve caps and seal
packings that can be inspected or replaced with standard tools. - Factory-tested: Every CWX4G25N is tested for flow rate, pressure consistency, and
seal integrity before leaving the production facility. - Drive compatibility: Integrates easily with electric motors or gasoline engines via
flexible couplers or direct drives for a variety of commercial and industrial setups. - OEM service kits: Annovi Reverberi supplies complete seal, valve, and o-ring kits to
keep maintenance quick, predictable, and cost-effective. - Compact frame: Versatile footprint allows installation in stationary systems or mobile
rigs where space and weight are at a premium.
Performance & Lifecycle Advantages
- Moderate-speed efficiency: 1,750 RPM operation reduces mechanical stress on the pump
and drive components, lowering total cost of ownership. - Extended component life: Robust mechanical design helps dampen vibration and protect
downstream accessories from excess pressure fluctuation. - Simple routine maintenance: Operators monitor crankcase oil, maintain clean inlet
filtration, and perform scheduled seal and valve changes for long-term reliability. - Lower wear on drive systems: Efficient operation at moderate speed reduces wear on
motors, couplers, and mounts, supporting longer service intervals.
Typical Applications for CWX4G25N
- Equipment washdown & fleet cleaning: Construction, rental, and transportation
fleets requiring daily high-pressure cleaning. - Manufacturing maintenance: Plant washdown, machinery cleaning, and production-line
sanitation requiring steady pressure and consistent flow. - Food-processing and sanitation systems: Applications that benefit from stable pressure
and durable materials in harsh, detergent-based environments. - Agricultural equipment cleaning: Tractors, harvesters, and implements exposed to mud,
fertilizer, and crop residues. - Professional wash facilities & mobile rigs: Car/truck washes and mobile cleaning
systems that need compact, reliable pumps for intensive daily use.
