Specifications

Proposal Number PSDF #P09-0004
A 3" ball valve shall be furnished from the tank to the pump complete with a flexible connection and shall be
enclosed in the pump compartment. The 3" valve shall be stainless steel and have an interior stainless steel
ball and shall have a locking manual control handle located on pump operator's panel. A built-in check valve
shall be provided in the tank to pump supply line to prevent the unintentional back filling of the water tank
through the line.
TANK REFILL
A 2" tank refill line shall be provided using a 2" quarter-turn full flow ball valve controlled from the pump
operator's panel with a manual locking handle. The tank refill shall be plumbed with high pressure flexible
piping and high pressure flexible piping stainless steel couplings.
TANK SUMP AND CONNECTIONS
There shall be one (1) sump standard per tank. The sump shall have a minimum 3” FNPT threaded outlet on
the bottom for a drain plug. This shall be used as a combination clean out and drain. All tanks shall have an
anti-swirl plate located above the dip tube.
There will be two (2) standard tank outlets: one for tank to sump suction line, and one for a tank fill line. All
tank fill couplings shall be backed with flow deflectors to break up the stream of water entering the tank, and
be capable of withstanding sustained fill rates of up to 1,000 GPM. All auxiliary outlets and inlets must meet
N.F.P.A. 1900 guidelines in effect at the time of manufacture.
TANK MOUNTING
The tank shall be mounted on the aerial torque box and shall be insulated from the torque box with hard
rubber insulators. The tank shall be designed on the free-floating suspension principal and shall not require
the use of hold downs. The tank shall be completely removable without disturbing or dismantling the
apparatus body structure.

"WARNING: DO NOT MIX BRANDS AND TYPES OF FOAM"
TANK MOUNTING
A tank mounting cradle shall be supplied. The tank is designed on the free-floating suspension principal and
shall not require the use of hold downs. The tank shall be completely removable without disturbing or
dismantling the apparatus body structure. The water tank cradle shall be designed to be completely
independent of the apparatus body to eliminate torsional stress loading in the body.
