Around-The-Pump Proportioner - Kit Down To 1/2% At 100-1400 GPM

The Darley Around-The-Pump Proportioner is a simple and inexpensive way to add foam capability to all discharges of a truck.

• It allows for different flow requirements separately or in any combination.
• A portion of the truck output goes through an eductor and back to the inlet side of the pump.
• A metering valve is adjusted for the correct foam percentages based on the total discharge.
• This system offers several advantages when compared to an inline eductor:
• Variable Flow Rate-the discharge rate can be adjusted for the specific application.
• The rate is infinitely variable up to the maximum flow of the unit.
• Variable Pressure-the system operates at any pressure above 120 psi.
• The pump operation is the same with foam or water.
• No Back Pressure Restrictions-the unit is not affected by hose length or elevation loss.
• No Nozzle Restrictions-the unit operates with any size or type of nozzle.
• Note: Maximum 5 psi Hydrant Pressure

• The pump Kit Includes: A. Eductor, B. Metering Valve, C. Check Valve, D. Water Valve, and E. Foam Valve Instruction Panel Plate
