RCV3G27-PKG Pump Package: Build a Professional Pressure Washer

When it comes to building or upgrading a pressure washer, Annovi Reverberi (AR) is one of the most trusted names in the business. Their RCV3G27-PKG pump package is designed for serious cleaning power, long-term durability, and easy installation—making it the ideal choice for contractors, property managers, and DIY builders.
Delivering 3.0 gallons per minute (GPM) at 2700 PSI, this horizontal hollow shaft pump provides the perfect balance of strength and efficiency. Whether you’re a contractor running light commercial jobs or a homeowner who demands professional-grade results, the RCV3G27-PKG is a smart solution.

Why the RCV3G27-PKG Stands Out
Unlike consumer-grade axial pumps, the RCV3G27-PKG is a triplex plunger pump. That means:

• It runs cooler under load.
• It lasts longer thanks to high-quality components.
• It’s fully serviceable and rebuildable, unlike throwaway axial pumps.

This design makes it especially appealing to professionals who are tired of replacing worn-out consumer pumps every season.

Key Specifications

• Max Flow: 3.0 GPM
• Max Pressure: 2700 PSI
• RPM: 3400
• Shaft Type: 3/4″ hollow shaft (horizontal)
• Engine Flange: F7 type

Included Accessories:

• Mini-Matic unloader with built-in bypass
• Thermal relief valve (TPP140-1/4A)
• Garden hose adapter (AR1264750)
• Quick-connect coupler (AL-QC3/8B)

With these factory-installed accessories, this pump package is plug-and-play, saving time for contractors and eliminating the guesswork for DIY builders.

Predator Engine Compatibility
The RCV3G27-PKG was designed to bolt directly onto small horizontal-shaft gas engines, especially the Predator 212cc engine from Harbor Freight.
Benefits of pairing with Predator:

• Affordable build: Predator engines are budget-friendly and easy to find.
• Direct fit: The 3/4″ hollow shaft slides right on for simple installation.
• Reliable performance: The Predator’s 6.5 HP output provides ample power to run 3.0 GPM @ 2700 PSI.

Other compatible engines include:

• Honda GX160 & GX200 – contractor-grade reliability.
• Briggs & Stratton small horizontals.
• Kohler SH series.
• Lifan 196cc models.

This flexibility lets you choose an engine based on budget, local availability, and long-term durability needs.

Advantages of the Pump Package
Most bare pumps require extra components before you can build a complete washer. With the RCV3G27-PKG, everything is included:

• Mini-Matic Unloader: Controls pressure and routes water into bypass when the trigger is released.
• Thermal Relief Valve: Protects the pump during bypass cycles by releasing overheated water.
• Garden Hose Adapter: Makes water supply hookup easy.
• Quick Connect Coupler: Fast hose attachment and nozzle swaps.

These features make the package a turnkey solution for both professional setups and DIY builds.

Applications: Where the RCV3G27-PKG Excels
The balanced output of 2700 PSI and 3.0 GPM makes this pump incredibly versatile.
Residential Cleaning

• Siding, decks, and patios.
• Driveways, sidewalks, and garage floors.
• Fence washing and paint prep.
• Vehicle, boat, and RV cleaning.

Light Commercial & Contractor Use

• Small fleet washing.
• Property maintenance services.
• Farm and landscaping equipment cleaning.
• Mobile contractor rigs and rental units.

It’s strong enough for commercial jobs yet safe and practical for homeowners who want professional results without overkill pressure.

Why 2700 PSI and 3.0 GPM Is the Sweet Spot
Some buyers assume that “more PSI is always better.” In reality, 3.0 GPM @ 2700 PSI is the ideal balance:

• Strong enough to blast away dirt, mildew, and loose paint.
• Gentle enough for siding, fencing, and painted surfaces without causing damage.
• Efficient flow rate that shortens cleaning times without wasting excess water.

This combination provides the best all-around performance for most residential and light commercial jobs.

DIY Build Process
One of the biggest selling points of the RCV3G27-PKG is how simple it is to build your own washer.

1. Choose your engine: Predator 212cc for affordability, Honda GX200 for premium durability.
2. Mount the pump: Slide the 3/4″ hollow shaft pump directly onto the engine crankshaft.
3. Install accessories: Attach the included unloader, thermal relief valve, and quick connects.
4. Add oil and fuel: Use non-detergent pump oil; fuel the engine.
5. Start cleaning: Connect hoses, start the engine, and spray with 2700 PSI power.

This DIY approach saves money and gives you control over your washer build.

Cost Savings with a DIY Predator + RCV Build
Pre-built washers with similar specs (3.0 GPM, 2700 PSI) often retail for $600–$900. With a Predator 212cc engine and the RCV3G27-PKG, you can typically build one for half the cost.
Even better, this approach gives you:

• Modular repairs: Replace the pump or engine separately if needed.
• Custom builds: Choose your hoses, guns, nozzles, and accessories.
• Higher-quality components: Better than most big-box store washers.

The result? A more durable, serviceable pressure washer for less money.

Long-Term Durability
Annovi Reverberi pumps are built with features that extend service life:

• Forged brass manifold for corrosion resistance.
• Stainless steel plungers for abrasion resistance.
• Replaceable valves and seals for easy rebuilding.
• Oversized bearings for cooler operation and longer lifespan.

This is a rebuildable, professional-grade pump, not a throwaway part.

Conclusion
The RCV3G27-PKG pump package is one of the most versatile and cost-effective ways to build a professional-grade pressure washer. With 3.0 GPM at 2700 PSI, it delivers the ideal balance of power and safety, making it perfect for both homeowners and contractors.
Pair it with a Predator 212cc or Honda GX200 engine, and you’ll have a powerful, reliable washer for half the cost of a pre-built unit. Add in AR’s quality construction, rebuildable design, and included accessories, and you have a package that’s hard to beat.
If you’re ready to upgrade or build your own pressure washer, the RCV3G27-PKG is the smart choice: affordable, durable, and designed for years of reliable cleaning performance.
