Comet P40 Softwash Skid 300 Psi 11 Gpm

Comet P40 Soft Wash Skid Pump – 11.5 GPM, 300 PSI, Chemical-Resistant Diaphragm System for Professional Cleaning

The Comet P40 Soft Wash Skid Pump is purpose-built for high-output, professional soft washing applications. Delivering up to 11.5 GPM at 300 PSI, this powerful 3-diaphragm pump is engineered to handle aggressive soft wash chemicals while maintaining long-term performance.

Crafted with chemical-resistant wet-end components, the P40 is compatible with sodium hypochlorite, surfactants, and other corrosive cleaners commonly used in mold, algae, and mildew removal. Additionally, its single-piece manifold design reduces leak points and simplifies service, helping minimize downtime on the job.

To further improve strength and efficiency, the P40 includes aluminum head plates that reduce flex under pressure and a metal oil cup for enhanced impact resistance. Moreover, its bolt-on pressure regulator allows for safe, precise control—without the risk of leaks during adjustment.

The pump also features molded inserts that stay locked in place, preventing unnecessary failures under field conditions. Whether you’re treating siding, roofs, stucco, or fences, this unit delivers reliable flow, steady pressure, and superior chemical compatibility.
