CWX1517N 4.0 GPM 2500 PSI Plunger Pump | CWX Series 950 RPM

Overview

CWX1517N – AR CWX Series Slow-Speed Triplex Plunger Pump
The AR CWX1517N is a heavy-duty industrial triplex plunger pump rated
4.0 GPM at 2,500 PSI and 950 RPM. This slow-speed CWX Series model is engineered for
continuous-duty cleaning and processing where smooth output, low vibration, and long service life are
mandatory. By prioritizing reliability over raw speed, it reduces mechanical stress on the crankshaft,
bearings, seals, and valves so the pump can run for extended intervals with predictable performance.

Key Features & Design Benefits

Hydraulic Performance

• 4.0 GPM @ 2,500 PSI: Delivers solid rinsing throughput and effective cleaning energy
  for industrial wash and process applications.
• Slow 950 RPM operation: Reduces wear, vibration, and noise compared to higher-speed
  designs, extending component life and improving operator comfort.
• Triplex plunger architecture: Three ceramic plungers balance crank motion for even
  fluid displacement, steadier pressure at the gun or header, and less pulsation in the line.
• Balanced hydraulics: Helps protect downstream accessories from pressure ripple and
  cavitation, supporting longer life for hoses, regulators, and unloaders.

Construction & Internal Components

• Forged brass manifold: Provides superior corrosion resistance, dimensional stability,
  and strength under continuous high-pressure use.
• Ceramic plungers: Ground and polished for a fine finish to minimize seal abrasion,
  reduce heat at the packings, and maintain consistent sealing over long run times.
• Stainless-steel valves: High-grade valves with precision springs and retainers seat
  positively, preserving volumetric efficiency and fast recovery on every stroke.
• Die-cast aluminum crankcase: Keeps weight manageable while maintaining rigidity;
  oil-bath lubrication continuously floods critical interfaces to lower friction and manage heat.
• Tapered roller bearings: Oversized bearings support the crankshaft under continuous
  load, holding alignment at 950 RPM and resisting brinelling during frequent starts and stops.
• Reduced heat generation: Slower piston velocity lowers temperature at the sealing
  interface, helping packings retain shape and sealing force over longer intervals.

Serviceability & Integration

• Service-friendly layout: Valve caps and seal assemblies are accessible with standard
  tools, and modular subassemblies shorten teardown during scheduled maintenance.
• Oil management: Sight glass and vented fill cap simplify oil checks and changes,
  supporting longer oil life and fewer heat-related maintenance events.
• Compact footprint: Straightforward mounting pattern fits skids, carts, and stationary
  frames; compatible with direct coupling to electric motors or gas engines using flexible couplers.
• Stainless inlet/outlet ports: Precision-threaded connections support leak-free makeup
  and long-term seal integrity with smooth internal flow paths.
• Factory-tested: Each pump is tested by Annovi Reverberi for pressure performance, flow
  accuracy, and seal integrity before shipment.

Typical Applications

• Continuous-duty sanitation lines: Food, beverage, and processing plants requiring
  steady pressure and long run times.
• Equipment degreasing & fleet washing: Construction, rental, and transportation
  yards needing reliable daily washdown.
• Manufacturing process cleaning: Rinse stations, tooling cleanup, and production
  equipment washdown where smooth discharge benefits multiple drops or tools.
• Construction & agricultural equipment washdown: Tractors, loaders, excavators,
  and implements exposed to heavy soils and residues.
• Mobile wash rigs: Skid- or trailer-mounted systems where lower vibration, quieter
  operation, and robust components protect accessories during transport.
