RCASS42G20E-F8-SX | 4.2 GPM 2000 PSI Left Shaft SS Head Pump

Overview

The Annovi Reverberi RCASS42G20E-F8-SX is a heavy-duty, stainless-steel
triplex plunger pump engineered for demanding washdown, industrial
cleaning, and process-rinse applications. Delivering up to 4.2 GPM at 2,000 PSI
and running at a slow 1,750 RPM, this pump is built to provide steady
pressure, long service life, and reliable performance in continuous-duty environments.

With a stainless-steel manifold head, precision ceramic plungers, and
premium sealing materials, the RCASS42G20E-F8-SX is ideal wherever corrosion resistance,
hygiene, and durability are priorities—such as food and beverage plants, pharmaceutical
production, marine environments, and chemical processing facilities. The integrated
F8 electric motor flange allows direct mounting to NEMA 56C motors, while
the left-hand shaft (SX) orientation helps designers optimize layouts in
compact skids, OEM frames, and mirrored multi-pump systems.

Performance & Pump Architecture

Triplex Plunger Design

• Three-plunger triplex architecture delivers smooth, pulse-reduced flow that improves nozzle performance and reduces vibration.
• Ceramic plungers resist abrasion and thermal shock, increasing seal life and lowering long-term maintenance costs.
• Stainless-steel head (SS) provides superior resistance to corrosion in washdown, caustic cleaning, and high-moisture environments.
• Heavy-duty crankshaft and bearings support continuous-duty operation at 1,750 RPM with excellent longevity.
• High-efficiency intake and discharge valves help maintain strong volumetric efficiency across the working pressure range.

Industrial-Duty Performance for RCASS42G20E-F8-SX

• Rated output: 4.2 GPM @ 2,000 PSI – a versatile combination for washdown, surface cleaning, and process rinsing.
• Slow-speed 1,750 RPM operation for cooler running, quieter performance, and reduced wear on internal components.
• Designed as an industrial plunger pump rather than a light-duty homeowner unit, supporting long run times and frequent duty cycles.
• Provides consistent pressure and flow for stable spray patterns and predictable cleaning results across multi-gun or multi-nozzle systems.

Applications & Industry Use Cases

Sanitation, Food & Beverage

• Meat and poultry plants requiring stainless components in high-moisture, chemical washdown zones.
• Dairy and beverage facilities where frequent caustic or chlorinated rinses demand corrosion-resistant pump heads.
• USDA-compliant washdown areas, packaging lines, and conveyorized cleaning tunnels.
• Commercial kitchens and central wash rooms with multiple reels and spray stations.

Industrial & Commercial Cleaning

• Plant washdown and equipment rinsing in chemical processing, plastics, and light manufacturing.
• Fleet and vehicle wash bays where 2,000 PSI and 4.2 GPM provide efficient cleaning without excessive surface damage.
• Marine and coastal facilities that require stainless wetted components to handle salt and humidity.
• General building maintenance including walls, floors, docks, loading areas, and containment pads.

OEM & System Builder Applications

• Skid-mounted electric pressure washer packages designed for indoor plant use or enclosed mechanical rooms.
• Custom CIP (Clean-in-Place) and rinse skids where stainless construction supports hygienic design.
• Enclosed pump modules for process equipment, mixers, tanks, or filling lines.
• Left-hand shaft (SX) orientation simplifies mirrored twin-pump systems where plumbing symmetry is important.

Installation & Integration

Mounting & Drive Configuration

• Direct 56C motor mount via the F8 flange means no separate base plate or belt drive is required in many builds.
• Compact, balanced housing is well-suited for skid frames, wall brackets, and enclosed cabinets.
• Align the motor and pump carefully to maintain smooth shaft engagement and prevent premature wear.
• Provide adequate ventilation and service access for oil changes, seal replacement, and valve service.

System Design Best Practices of RCASS42G20E-F8-SX

• Use proper inlet filtration to protect stainless internals, seals, and nozzles from grit and debris.
• Maintain positive inlet pressure with sufficiently large supply lines to avoid cavitation at 4.2 GPM.
• Pair with a properly sized unloader valve, pressure gauge, and safety relief rated for 2,000 PSI.
• Consider stainless or coated fittings and manifolds downstream to maximize corrosion resistance throughout the system.

Maintenance & Serviceability

Service-Friendly Design

• Accessible head bolts and valve caps make periodic valve inspection and replacement straightforward for technicians.
• External oil fill and drain ports support quick crankcase oil changes on scheduled intervals.
• Ceramic plungers and robust seal packs are designed for long life but can be serviced as part of planned maintenance.
• Follow AR’s recommended oil change, seal inspection, and torque check schedule to maximize uptime.
• When installed with good filtration, proper inlet conditions, and correct unloader settings, the RCASS42G20E-F8-SX delivers years of reliable service in demanding industrial environments.
