TANK TO PUMP VALVE
A 3" full flow ball valve shall be installed between the fire pump and the water tank. The connection between the tank and
the pump shall be capable of the flow recommendations as set forth in the latest edition of NFPA 1901. The valve shall be
flanged to bolt directly to the pump and shall incorporate a chromium plated bronze ball. The remaining internal moving
parts shall be stainless steel for years of dependable service. A non collapsible flexible hose shall be incorporated into
the tank to pump plumbing to allow movement in the line as the chassis flexes to avoid damage during normal road
operation.
The tank to pump valve shall be controlled from the pump operator's panel.
- Valve(s) shall be controlled with a push/pull type chromed "T" handle with adjustable linkage connected to the
valve. The control handle shall be located adjacent to the plumbing connection.
DISCHARGES
A minimum of two 2-1/2 in. (65 mm) outlets shall be provided on any pump rated at 750 gpm (3000 L/min) or greater, and
a minimum of one 2-1/2 in. (65 mm) outlet shall be provided on any pump rated at less than 750 gpm (3000 L/min).
All 1-1/2" (65 mm) or larger discharge outlet connections shall be equipped with male National Hose Threads (NST).
Adapters with special threads or other means for hose attachment shall be permitted to be attached to any outlets.
The piping and valves supplying any pre-connected 1-1/2 in. (38 mm), 1-3/4 in. (45 mm), or 2 in. (52 mm) hose line,
including the piping to the pre-connected hose storage areas shall be at least 2 in. (52 mm) in size.
All discharge outlet connections, except connections to which a hose will be pre-connected, shall be equipped with
caps
or closures capable of withstanding a hydrostatic gauge pressure of 100 psi (700 kPa) over the maximum pump close-off
pressure or 500 psi (3400 kPa), whichever is greater.
Where adapters are provided on the discharge outlet connections, the closures shall fit on the adapters.
Caps or closures for outlet connections smaller than 4 in. (100 mm) shall remain secured to the apparatus when
removed
from the connection.
Each discharge outlet shall be equipped with a valve that can be opened and closed smoothly at pump discharge gauge
pressures of 250 psi (1700 kPa).
The flow-regulating element of each valve shall not change its position under any condition of operation that involves
discharge pressures to the maximum pressure of the pump; the means to prevent a change in position shall be
incorporated in the operating mechanism and shall be permitted to be manually or automatically controlled.
Any 3 in. (75 mm) or larger discharge valve shall be a slow-operating valve.
All 1-1/2 in. (38 mm) or larger discharge outlets shall be equipped with a drain or bleeder valve having a minimum
3.4 in.
(19 mm) pipe thread connection for draining or bleeding off pressure from a hose connected to the outlet.
Any 2 in. (52 mm) or larger discharge outlet that is located more than 42 in. (1070 mm) off the ground to which hose is to
be connected and that is not in a hose storage area shall be supplied with a sweep elbow of at least 30degrees
downward.
The completed apparatus shall have the following discharge(s);
