RKA65G20HE-F17 6.5 GPM 2000 PSI | Nickel Triplex Pump

Annovi Reverberi RKA65G20HE-F17 Triplex Plunger Pump

Overview

The Annovi Reverberi RKA65G20HE-F17 is a professional-grade triplex plunger pump
engineered for commercial and light industrial pressure washer systems that require
high flow, dependable pressure, and long-term durability. Delivering
6.5 GPM at 2,000 PSI while operating at a controlled 1,750 RPM,
this pump is purpose-built for high-capacity cleaning tasks where coverage speed,
rinse efficiency, and equipment longevity are critical.

As part of the RKA Series, the RKA65G20HE-F17 is designed around slow-speed operation and
robust internal components. Its F17 electric flange with a 1-1/8 inch hollow shaft
allows direct mounting to NEMA 182–184 frame electric motors, resulting in compact,
efficient, and low-vibration system builds. This configuration makes the pump an excellent
choice for fixed wash stations, industrial skids, fleet wash systems, and OEM equipment
where reliability and clean electric power are preferred.

Performance & Duty Point

With a duty point of 6.5 GPM at 2,000 PSI, the RKA65G20HE-F17 is optimized for
high-throughput cleaning rather than extreme cutting pressure. This balance
produces strong mechanical cleaning action while maintaining a wide spray pattern,
allowing operators to cover large areas quickly with fewer passes. The moderate pressure
rating also helps protect coated surfaces, painted steel, rubber components, and
finished concrete from unnecessary damage.

• High flow output: 6.5 GPM accelerates rinsing and debris transport.
• Controlled pressure: 2,000 PSI provides effective cleaning without over-aggression.
• Slow-speed design: 1,750 RPM reduces heat buildup and internal wear.
• Efficient power demand: Approximately 13 EBHP supports practical electric motor sizing.

Construction & Materials

The RKA65G20HE-F17 is built using premium materials selected for durability in demanding
commercial environments. The nickel-plated brass manifold offers superior resistance
to corrosion, chemical exposure, and mineral scaling compared to standard brass heads.
This makes the pump well suited for frequent detergent use, reclaimed water systems,
and facilities with hard or variable water quality.

Internally, solid ceramic plungers provide excellent hardness and thermal stability,
maintaining smooth sealing surfaces over long service intervals. Ceramic plungers resist
abrasion and heat transfer into the sealing system, helping to extend seal life and
maintain consistent pressure output. Stainless steel valves ensure reliable
sealing and smooth flow control under continuous cycling.

Drive End & Lubrication

The pump utilizes an oil-bath crankcase designed to support continuous-duty operation.
A generous oil capacity, combined with slow-speed rotation, helps maintain stable oil
temperatures even during long cleaning cycles. Integrated service features allow
maintenance staff to monitor and service the pump quickly without disassembly.

• Oil-bath lubrication protects bearings, crankshaft, and connecting rods.
• Vented dipstick supports proper crankcase ventilation.
• Oil sight glass enables fast visual oil-level and condition checks.
• Slow-speed operation minimizes friction and mechanical stress.

Installation & System Integration

The F17 flange and 1-1/8 inch hollow shaft configuration allows the RKA65G20HE-F17
to mount directly to common electric motors without complex adapters or couplings.
Direct mounting simplifies alignment, reduces vibration, and shortens installation time,
making it ideal for both OEM production and field-built systems.

• Direct electric motor mounting for compact, clean system layouts.
• Compatible with belt-drive configurations where layout flexibility is required.
• Standard inlet and outlet ports simplify plumbing and component selection.
• Works seamlessly with unloaders, regulators, and safety relief valves.

Typical Applications

The RKA65G20HE-F17 excels in applications that demand fast coverage, reliable pressure,
and continuous-duty capability:

• Fleet washing: Trucks, buses, trailers, and heavy equipment.
• Commercial cleaning: Parking decks, sidewalks, warehouses, and loading docks.
• Industrial washdown: Machinery, production floors, and maintenance areas.
• Agricultural facilities: Equipment cleaning, livestock areas, and sanitation tasks.
• Municipal operations: Public works equipment and facility maintenance.
