1-Way YPT-LV Concrete Foamer

Model # 933515-YPT

The 1-Way YPT-LV Concrete Foamer is a foam applicator for projecting highly corrosive chemicals such as those used to remove concrete and for aluminum brightening. This acid-resistant system uses a rugged 1/4" Yamada air-operated, double-diaphragm pump to pump water and drive the venturi LVHC foamer which draws chemical concentrate through precision metering tips to create dilution ratios of 2.5:1 (or weaker) with no chemical passing through the air pump. If a stronger ratio is required, this system includes an extra chemical pickup on the suction side of the pump for up to a 1:1 ratio. Compressed air is injected into the solution to create rich, clinging foam which is then projected through the foam hose, wand and fan nozzle.

Key Features
  • Rugged Yamada AODD pump with Teflon diaphragms provides the water pressure to drive a LVHC venturi foamer
  • The LVHC venturi foamer body draws chemical concentrate, optimizes the flow rate and produces the ideal amount of foam to avoid excessive chemical run-off
  • Able to provide dilutions ratios up to 1:1
  • No chemical passes through the pump for dilution ratios of 2.5:1 and weaker
  • Projects rich, clinging foam which increases chemical contact time and effectiveness
  • Foaming expands the chemical and reduces over-application by providing visual assurance of coverage
  • Fan pattern nozzle for quick coverage
  • Adjustable foam consistency (wet/dry)
  • Corrosion resistant wetted components ensure durability and years of reliable service
  • See other Lafferty acid sprayers and foamers in Catalog 8
