In-Line Balanced Pressure (ILBP) Proportioning Units


Chemguard UL Listed in-line balanced-pressure proportioning (ILBP) systems meter the correct proportion of foam concentrate into the water stream over a wide range of flows and pressures. Designed for applications requiring large quantities of foam concentrate and/or where the proportioners must be installed great distances from the tank, the flexible Chemguard ILBPs can accommodate an almost infinite number of risers, each with a different size proportioner and each offering a wide range of flow.

Suitable for all types of foam concentrates, ILBPs can operate in several locations remote from the foam concentrate pump and atmospheric foam storage tank. Completely self contained, Chemguard ILBPs include all necessary components – ratio controller, pressure-balancing diaphragm valve, duplex gauge, check valve, and manual ball valve. Chemguard manufactures 5 standard ILBP proportioners: 2 ½ inch, 3 inch, 4 inch, 6 inch, and 8 inch. Flow rates range from 100-400 gallons per minute for the smallest to 900-4,200 gallons per minute for the 8 inch, depending on foam.
