Proposal Number PSDF #P09-0004

DRAIN DISCHARGES

The 3/4 inch drain valves shall be equipped with 90-degree fittings to direct the discharge water beneath the

pump module away from the pump operator's panel.

AKRON BALL VALVES

All ball valves shall be manual control 1/4 turn Akron heavy duty valves with stainless steel ball unless

specified otherwise.

The valves shall have an all cast brass body with flow optimizing stainless steel ball, and dual polymer seats.

The valve shall be capable of dual directional flow while incorporating a self- locking ball feature using an

automatic friction lock design and specially designed flow optimizing brass ball. The valve shall not require

the lubrication of seats or any other internal waterway parts, and be capable of swinging out of the waterway

for maintenance by the removal of six bolts.

TANK TO PUMP

The tank to pump piping shall be capable of delivering water to the pump at a rate of five hundred (500)

gallons per minute. This flow shall be sustained while pumping to a minimum of 80% of the certified tank

capacity with the apparatus on level ground. No exceptions are allowed to this section.

The tank to pump line shall run straight, without elbows, from the pump to the front face of the water tank

and down into the tank sump. A rubber coupling shall be included in this line to prevent damage from

vibration or chassis flexing. The tank to pump line shall be plumbed with 3" Schedule 40 stainless steel high

pressure pipe.

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.

FOAM SYSTEM

The foam system will operate as a Class A system.

A Hale "FoamLogix 2.1A" 2.1 GPM foam system shall be supplied on the apparatus. The apparatus shall be

equipped with an automatic electronically controlled, direct injection, rotary gear pump, discharge side foam

proportioning system. Foam proportioning operation shall be based on direct measurement of water flow,

and remain consistent within the specified flows and pressures.
