Proposal Number PSDF #P09-0004
The acceptable tank manufacturers are UPF or ProPoly.
The partitions shall be designed to provide maximum water flow and meet NFPA rules
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.
EXTERNAL FOAM TANK
A thirty (30) gallon polypropylene foam concentrate tank shall be furnished.
The foam tank shall be plumbed to the on board "Class A" foam system. A drain valve shall be provided at
the lowest point of the foam tank. The foam tank shall drain shall directly to the surface below the apparatus
without contacting other body or chassis components. The following labels shall be attached to the foam
tank:
"CLASS A FOAM TANK FILL"
"WARNING: DO NOT MIX BRANDS AND TYPES OF FOAM"
TANK MOUNTING
A tank mounting cradle shall be supplied. The tank mounting cradle shall consist of a minimum of seven (7)
crossmembers and two (2) full tank length longitudinal members. The tank shall rest on the tank mounting
subframe, and shall be insulated from the sub-frame with a 2-1/2" wide rubber insulator. The tank shall sit
cradle-mounted using four (4) corner angles of 8" x 8" x 4" x .250" welded directly to the tank sub-frame.
The angles shall keep the tank from shifting left to right or front to rear. 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 hosebed cross-braces shall
act as water tank retainers. The water tank cradle shall be designed to be completely independent of the
apparatus body to eliminate torsional stress loading in the body.
APPARATUS BODY DESIGN AND CONSTRUCTION
The apparatus body shall be built of stainless steel and shall be designed exclusively for Fire Service use.
The overall body width shall be 100 inches wide and shall be constructed in accordance with current NFPA
requirements. All metal work shall be free of sharp edges, objects or corners. No exceptions are allowed to
this requirement.
The pump module is to be completely separate from the main body to prevent damage due to flexing.
