The motor speed is constantly adjusted to main tain
the operator selected foam concentrate injection
rate. Since the system is flow based, injection rate
remains constant regardless of changes in system
pressure or the number of discharges that are open
(within the limits of the sytem).
The maximum rated foam concentrate flow, in
gallons per minute, is denoted by the model
number. Table 1: “Maximum Foam Solution
Flows” shows the system capacity at various foam
concentrate injection rates for the Hale FoamLogix
2.1A and 1.7APH units.

LOW PRESSURE STRAINER
A low pressure foam concentrate strainer is mounted
at the inlet of the foam pump. The strainer protects
the pump from debris that might accumulate in the
foam concentrate tank. The strainer/valve assembly
has a composite nonme tallic housing with stainless
steel mesh strainer element and includes a service
shut-off valve.
The valve inlet offers 1/2” NPT (13 mm) threads,
with a fitting to connect a 1/2” (13 mm) ID foam
concentrate suction hose.
The strainer and valve are low pressure devices
and are designed for installations where the
strainer IS NOT subject to HIGH pressure flush ing
water.
