The BE 85.400.003 is a high-draw, upstream chemical injector engineered for heavy-duty cleaning where high-pressure soap application is required. By installing this on the inlet side of the pump, it introduces detergent into the water stream before it is pressurized. This allows the soap to be delivered at the machine's maximum PSI—ideal for stripping grease from heavy machinery, deep-cleaning concrete, or industrial wash-bay applications. It features an adjustable brass metering valve for precise chemical control and comes with garden hose-style connections for a direct, tool-free fit onto your pump's water intake.
