Detailed Description
The SIMPSON Water Blaster WB60824 is engineered for commercial and industrial use. Its belt-driven system reduces heat and vibration, extending both engine and pump life — ideal for long continuous jobs. The CRX 420 engine provides dependable power while the AAA triplex pump, with ceramic pistons and thermal relief, resists wear and overheating during tough jobs.
This unit includes a 50-foot steel-braided hose that lets you keep the machine positioned away from the work area while still reaching vehicles, buildings, or siding. The durable frame and dual-belt separation between engine and pump lower maintenance needs and reduce pump fatigue. Simpson backs the commercial product with solid coverage: a 3-year limited engine warranty, 5-year pump warranty, and 10-year frame warranty (plus 90-day accessories warranty), demonstrating confidence in its commercial reliability.
