AR60 Bare Pump & Gearbox Assembly — 15.6 GPM @ 290 PSI
$1,658.33
The AR60 pump and gearbox assembly is rated at 15.6 GPM at 290 PSI — a high-flow, low-pressure combination built specifically for softwash work rather than high-pressure cleaning. This pairing mounts to a 3/4" keyed horizontal shaft motor such as a Honda GX series engine.
Softwash is a fundamentally different job than pressure washing. Instead of relying on pressure to remove contamination, it uses volume and chemistry — applying cleaning solution at high flow and low pressure so the chemical does the work. That's why roof cleaning and house washing use pumps like this rather than the 3000+ PSI triplex pumps found on surface cleaning rigs.
The pump and gearbox come assembled, which removes the alignment and torque risk of pairing them yourself. Grime Task Force stocks softwash-specific equipment because the requirements genuinely differ from pressure washing, and using the wrong pump for the application damages both equipment and results.
Frequently Asked Questions
What are the output specs? 15.6 GPM at 290 PSI — high flow, low pressure, built for softwash applications.
What engine does this mount to? A 3/4" keyed horizontal shaft motor, such as a Honda GX series engine.
Why low pressure? Softwash relies on chemical dwell and volume rather than pressure, which is safer for roofs, siding, and painted surfaces.
