Simpson Super Brute SB3555 3,500 PSI 5.5 GPM Gas Pressure Washer
Simpson Super Brute SB3555, 3,500 PSI at 5.5 GPM
The Simpson Super Brute SB3555 delivers 3,500 PSI at a massive 5.5 GPM, driven by a Vanguard V-Twin engine with electric start. That 5.5 GPM flow rate is among the highest available in a portable cold water pressure washer, which means faster rinse times and more square footage cleaned per hour on large commercial jobs.
Vanguard V-Twin Engine with Electric Start
The Vanguard V-Twin engine is built to power high-demand commercial equipment for extended periods. It produces the torque needed to drive a pump at 5.5 GPM without straining, and electric start eliminates pull-cord hassle. Low oil shutdown protects the engine during long work days on construction sites, fleet yards, and industrial facilities.
Comet Triplex Pump with Axialign System
The Comet industrial triplex pump on the SB3555 is sized to handle the 5.5 GPM flow rate that sets this unit apart from standard commercial pressure washers. The Axialign adjustment system allows pump alignment and maintenance with a single bolt adjustment, simplifying upkeep. A built-in coil heats water temperature 100 degrees above the incoming water source, with a high-temperature limiting switch for safe operation. The 50-foot steel-braided Armor Hose ships standard.
