The FoaMidget is a simple, inexpensive and portable. It is a self
contained around-the-pump foam proportioner that instantly converts a
municipal water pumper into a foam proportioning pumper. The
proportioner is simply threaded into the 2.5" (65 mm) auxiliary suction
connection on the water pump and fed from a 1.5" (38 mm) discharge
outlet.
The foam pickup tube is inserted into the foam container and the
appropriate valve setting dialed into the proportioner body. The
FoaMidget allows for different flow requirements in any flow
combination. A portion of the water pump output passes through the 1.5"
(38 mm) hose to the eductor where foam concentrate is metered into the
water stream. The foam solution then passes through the auxiliary water
pump suction and into the main water pump stream where it is mixed and
distributed to all open outlet connections.
Pump pressures between 125 PSI (9 bar) and 250 PSI (17 bar) are
recommended. As with any around-the-pump type system all pump outlets
will have either foam or water at the same time. Pump suction pressure
from a hydrant is limited to 5 PSI (0.3 bar) so you may have to gate
down your inlet from the hydrant in order to keep outside pressures
down. If drafting this is not a problem as you will have negative
pressure at your pump.
