Stealth P40 Soft Wash Skid – 11 GPM, 300 PSI, CRX 210 Pull Start

Stealth P40 Soft Wash Skid – 11 GPM, 300 PSI, CRX 210 Pull Start

The Stealth P40 Soft Wash Skid is a professional, high-flow chemical application system built around the proven Comet P40 diaphragm pump, a CRX210 pull-start engine, and Stealth's purpose-built 6061-T6 commercial aluminum skid. Delivering up to 11 GPM at 300 PSI, the SSW-P40-C gives soft wash contractors the solution volume and reach needed for roof cleaning, house washing, multi-story properties, commercial buildings, and other high-production exterior cleaning applications.

Rather than adapting a conventional pressure washer for chemical application, the P40 is built around a gear-driven, three-diaphragm pump platform designed for high-volume spraying. The combination of 11 GPM flow and 300 PSI gives contractors the ability to move substantial solution, cover large areas efficiently, and reach elevated surfaces while maintaining the lower-pressure application characteristics required for soft washing.

The pump is paired with Stealth's commercial aluminum skid platform, constructed from precision-cut 6061-T6 structural aluminum for strength, reduced weight, and corrosion resistance. Integrated vibration isolation, improved component access, and stainless steel hardware create a professional platform designed for installation on trailers, truck beds, and custom soft wash, agricultural spraying, or pesticide spraying rigs.

For contractors building a dedicated high-output soft wash system, the Stealth P40 combines proven commercial components with a purpose-built platform designed around the way professional spray equipment is actually installed, serviced, and used in the field.

Introducing the Stealth Soft Flow Series

The Stealth Soft Flow Series is Stealth's professional line of high-volume chemical application equipment built for soft washing and other spray-intensive applications.

Soft Flow systems are designed around the demands of moving chemical efficiently, maintaining consistent solution delivery, and supporting the long spray runs and demanding workflows encountered by professional operators.

Rather than adapting conventional pressure washing equipment to chemical application, Soft Flow systems are built around spray-specific pump platforms and chemical-handling requirements. The series supports professional soft washing, exterior cleaning, property treatment, pest control, lawn care, and agricultural spraying, with configurations matched to different flow, pressure, and application requirements.

The Stealth P40 represents the high-output gas-powered side of the Soft Flow Series. Its 11 GPM Comet P40 diaphragm pump, gear-driven configuration, commercial engine, and Stealth aluminum skid create a purpose-built platform for contractors who depend on high-volume chemical application every day.

Soft Flow: Engineered for Spray-Centric Pros.

Why 11 GPM Matters for Professional Soft Washing

Higher flow isn't simply a bigger number. For a soft wash contractor, GPM directly affects how quickly solution can be delivered and how much area can be covered.

At up to 11 GPM, the Stealth P40 is designed for contractors who have outgrown lower-flow chemical application systems.

• Reach Elevated Surfaces: High solution volume supports applications where contractors need to reach roofs, peaks, and upper building surfaces from the ground.

• Cover More Surface Area: Apply solution across large roofs, siding, commercial properties, and other expansive surfaces efficiently.

• Reduce Application Time: Increased flow can reduce the amount of time spent applying solution across large jobs.

• Support High-Production Workflows: Well suited for contractors moving through multiple properties or large commercial cleaning projects.

• Built for Larger Soft Wash Rigs: The P40 platform pairs naturally with high-flow proportioning, larger-diameter hose, commercial hose reels, and professional tank systems.

Frequently Asked Questions

What is a Comet P40 soft wash system?

A Comet P40 soft wash system uses a gas-powered, gear-driven diaphragm pump to move high volumes of cleaning solution at substantially lower pressure than a conventional pressure washer.

The Stealth P40 pairs the Comet P40 three-diaphragm pump with a CRX210 engine and Stealth commercial aluminum skid to create a complete high-flow platform for professional chemical application.

How much flow and pressure does the Stealth P40 produce?

The Stealth P40 is rated for up to 11 GPM and 300 PSI.

Its combination of high flow and moderate pressure is designed around high-volume soft wash application and chemical cleaning rather than the thousands of PSI produced by conventional pressure washing equipment.

What can an 11 GPM soft wash system be used for?

The Stealth P40 is well suited for:

• Roof cleaning (low-pressure)

• House washing and large siding applications

• Multi-story properties (high-reach spraying)

• Commercial building exteriors and storefronts

• Property maintenance and multi-family complexes

• High-volume chemical application and rapid rinsing

• Agricultural spraying, greenhouse disinfecting, and crop protection
  

• Lawn care, turf management, and liquid fertilization

• Commercial pest control, perimeter treatments, and liquid insecticide application
• Professional exterior cleaning

Its high flow is particularly useful when coverage, reach, and application speed are priorities.

Is the Comet P40 designed for sodium hypochlorite?

The P40 is built specifically for professional chemical application and uses polypropylene and stainless steel wet-end components with Viton diaphragms and O-rings, making it suitable for the bleach-based solutions commonly used in professional soft washing.

As with any chemical application equipment, proper flushing and maintenance remain important to component life.

Is the Stealth P40 gear driven?

Yes. The Comet P40 is paired with the CRX210 through a gear-drive system.

The gearbox provides the reduction required for the diaphragm pump while creating a compact engine-and-pump configuration suited to trailer and skid installations.

Does the CRX210 version require a starting battery?

No. The CRX210 is pull start, eliminating the need for a dedicated starting battery for the engine.

This can be particularly useful for contractors looking for a straightforward gas-powered soft wash platform without adding an electric-start circuit to the machine.

What size proportioner should I use with an 11 GPM P40?

For a high-flow system such as the P40, the proportioning system needs to provide sufficient inlet capacity without unnecessarily restricting pump supply.

The Stealth SP-1 1" Soft Wash Proportioner is designed for high-flow gas-powered soft wash systems, including the Comet P40, with 1" water and chemical metering circuits and a 1" mixed-solution outlet.

Can the Stealth P40 be installed on a pressure washing trailer?

Yes. The Stealth P40 skid is designed for installation on pressure washing trailers, soft wash trailers, truck beds, flatbeds, and custom mobile cleaning rigs.

Its 6061-T6 aluminum skid provides a dedicated mounting platform while keeping the engine, pump, and service points accessible.

What is the difference between the CRX210 and Honda GX200 Stealth P40?

Both configurations use the Comet P40 gear-driven diaphragm pump and Stealth commercial aluminum skid platform and are designed around the same high-flow soft wash application.

The primary difference is the engine. The SSW-P40-C uses the CRX210 pull-start engine, while the SSW-P40-H uses the Honda GX200 pull-start engine. The CRX210 features a slightly larger displacement and offers a reliable, cost-effective commercial build. It includes a 3-year commercial warranty backed by FNA’s service network
