The New AR45-SW Soft Wash Pump

The AR45-SW is the latest evolution of the AR45 platform for soft wash applications, replacing the previous AR45LFP-GR-GCI used on earlier Stealth AR45 systems.

While the core diaphragm-pump architecture remains familiar, the new AR45-SW introduces several changes to the pump's head and discharge-side construction.

Reinforced Head Design

The new AR45-SW incorporates reinforcing plates around the pump heads, adding structural support to the head assemblies.

The reinforcement is intended to help control movement and flex across the pump heads during operation while retaining the chemical-resistant pump architecture required for soft wash applications.

Redesigned Outlet Manifold

One of the most visible changes is the new outlet manifold assembly.

Rather than the previous ring-style outlet arrangement, the AR45-SW brings the discharge side together through a more consolidated manifold configuration. Stainless steel reinforcement ties the assembly together and provides additional structural support around the discharge side of the pump.

For professional users familiar with previous generations of the AR45, this represents one of the most significant physical changes to the new AR45-SW.

Straight 3/4" Bypass Connection

The AR45-SW now incorporates a straight 3/4" bypass hose barb, replacing the previous angled bypass configuration.

This provides a more direct connection point when incorporating the regulator's bypass circuit into the final soft wash plumbing layout.

1/2" Threaded Outlet

The new pump retains a 1/2" threaded discharge outlet, allowing the final discharge connection to be configured around the requirements of the completed system.

Stealth Commercial Aluminum Stealth Skid

Every Stealth Sprayers machine is now built on a commercial aluminum skid platform. Constructed from precision-cut 6061-T6 structural aluminum, the skid provides exceptional strength while remaining lightweight and corrosion resistant.

Unlike generic mounting rails commonly found on commercial cleaning equipment, the Stealth skid is purpose-built for professional systems, featuring a clean layout, improved service access, integrated vibration isolation, and laser-cut STEALTH branding that gives the AR45-SW a premium, professional appearance on trailers, truck beds, and mobile wash rigs.

The standardized platform also creates a consistent equipment architecture across Stealth's professional pressure washing and soft washing systems.

Why 11.4 GPM Matters for Professional Soft Washing

Soft washing depends on more than pressure. Solution volume is a major contributor to application speed, coverage, and effective reach.

With output up to 11.4 GPM, the Stealth AR45-SW is designed for contractors moving significant amounts of solution across roofs, siding, large homes, commercial buildings, and other exterior surfaces.

Higher flow can help contractors cover more surface area quickly and reduce the amount of repositioning required across larger structures. That makes high-output gas-powered diaphragm systems particularly valuable for contractors whose productivity depends on completing multiple or larger properties efficiently.

Actual output and reach at the applicator depend on the complete system configuration, including proportioner, supply plumbing, hose diameter and length, fittings, nozzle selection, and other components.

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 includes configurations for professional soft washing, exterior cleaning, property treatment, pest control, lawn care, and agricultural spraying, with each system matched to the flow, pressure, and chemical-delivery requirements of its intended application.

The Stealth AR45-SW represents the high-output gas-powered side of the Soft Flow Series. Its 11.4 GPM AR45-SW diaphragm pump, Honda GX200 engine, gear-driven configuration, and commercial aluminum Stealth skid provide a purpose-built platform for contractors who depend on high-volume chemical application every day
