Dual Pump FPV-PD Concrete Sprayer / Foamer

Model # 933712-V

The Dual Pump FPV-PD Concrete Sprayer / Foamer is a combination chemical spray and foam applicator for use with highly corrosive chemicals such as those used to remove concrete and for aluminum brightening. This acid-resistant system uses 2 Flojet air-operated, double-diaphragm pumps to draw ready-to-use chemical solutions from static tanks. Compressed air is injected into the foaming solution to greatly increase volume and coverage ability and rich, clinging foam is projected through the foam hose, wand and fan nozzle. The other solution is projected as a chemical spray through a separate dedicated hose.

Key Features
  • 2 pumps draw ready-to-use chemicals independently allowing the unit to foam and spray simultaneously
  • The chemical flow rate is regulated to match the mid-range of the air pump's specified operating range which protects the pump from running, repetitively, at maximum capacity
  • Rich, clinging foam increases chemical contact time and effectiveness and provides visual assurance of coverage
  • The foamer body optimizes the volume and produces the ideal amount of foam to avoid excessive run-off
  • Adjustable foam consistency (wet/dry)
  • Projects the second solution as a medium volume spray
  • Fan pattern foam and spray nozzles for fast coverage
  • Corrosion resistant wetted components ensure durability and years of reliable service
