CR18-1000 | Ultra High Pressure Plunger Pump 4.75 GPM 14500 PSI

CR18-1000 Ultra-High-Pressure Triplex Plunger Pump — 4.75 GPM at 14,500 PSI

The AR CR18-1000 is an ultra-high-pressure triplex plunger pump engineered by Annovi Reverberi (AR) for the most demanding industrial cleaning, cutting, hydro-blasting, and surface preparation environments. Rated at 4.75 GPM and 14,500 PSI at a low 1,000 RPM, this Series 418 CR pump delivers exceptional hydraulic power while dramatically reducing heat buildup, mechanical wear, and noise compared to high-speed alternatives.

Built around a 35 mm solid stainless-steel shaft (N version) and a forged stainless-steel pump head, the CR18-1000 is purpose-built for continuous-duty industrial operation. Weighing 136 lbs and factory-tested under full load, this pump is trusted worldwide by OEM skid builders, industrial contractors, shipyards, and water-jetting specialists who require consistent, reliable ultra-high-pressure output day after day.

Whether you’re mounting it on a custom skid, integrating it into an automated cleaning system, or pairing it with a diesel or electric drive unit, the CR18-1000 is the high-flow centerpiece of any serious high-pressure system.

• Weight: 136 lbs — substantial, skid-ready construction
• Inlet: 1-1/2″ F | Outlet: 1″ F
• Oil Capacity: 137 oz for extended lubrication intervals

Premium Construction & Materials

• Stainless-steel pump head (Series 418) machined from a single forged block — resists corrosion, chemical attack, and pressure fatigue
• 35 mm solid stainless-steel crankshaft (N version) provides superior torsional strength and precise balance under continuous load
• Ceramic plungers with precision-polished surfaces minimize friction, reduce seal wear, and extend service intervals dramatically
• Frictionless bronze connecting rods deliver smooth, low-maintenance power transfer between crankshaft and plungers
• Viton O-rings rated for aggressive fluids and high-temperature operation — standard across all wetted components
• Die-cast aluminum crankcase with oil-bath lubrication maintains thermal stability during extended runtime
• Oversized tapered roller bearings absorb radial and axial loads, minimizing vibration under heavy-duty cycles
• Vented oil cap and sight glass for quick, tool-free oil level inspection without downtime
• CSID stamp rating: 3 — certified for high-pressure system compliance where required

Design & Integration Advantages

• Horizontal pump orientation simplifies skid mounting, frame integration, and direct-drive coupling
• 35 mm solid shaft supports direct coupling to electric motors, diesel engines, hydraulic drives, and PTO systems without adapters
• Compact, heavy-duty frame fits standard skid footprints used in industrial and OEM builds
• Italian precision machining at Annovi Reverberi’s facilities ensures tight tolerances and repeatable performance across every unit
• Factory load-tested prior to shipment — verified flow, pressure, and seal integrity before it reaches your system
• Compatible with AR safety valves, unloaders, regulators, and bypass systems for complete turnkey high-pressure solutions
• Maintains stable, consistent pressure output under fluctuating demand — ideal for precision-controlled automated processes

Ideal Applications for the CR18-1000

• Shipyard & marine maintenance — hull cleaning, paint stripping, and marine coating removal
• Industrial surface preparation — concrete scarifying, rust removal, and coating adhesion prep
• Hydro-blasting & water-jetting — tank cleaning, descaling, and tube cleaning in petrochemical facilities
• Pipeline flushing & hydrostatic testing — pressure testing pipelines, vessels, and high-pressure assemblies
• Industrial equipment cleaning — degreasing heavy machinery, heat exchangers, and process equipment
• Abrasive waterjet cutting support — consistent high-pressure feed for cutting systems
• Municipal & utility maintenance — sewer jetting, drain cleaning, and infrastructure cleaning
• OEM skid and system builds — where a reliable, high-pressure pump core is required

Maintenance & Serviceability

• Open-access design allows plunger, seal, and valve service without special tools — reducing labor time and downtime costs
• Standardized AR service kits (seals, valves, O-rings) are widely available for fast in-field rebuilds
• Initial oil change recommended at 50 operating hours, then per duty-cycle schedule — use SAE 30 non-detergent or AR-approved pump oil
• Inlet filtration required — minimum 20-mesh strainer protects plungers and valves from particle contamination
• Engineered viton packings and seals deliver extended service life under continuous high-pressure cycling
• Routine inspection of oil level, inlet pressure, and outlet fittings ensures maximum pump longevity — recommended before every shift in heavy industrial use
