shaft in a bronze body with multiple ports. The drain valve control shall be mounted on the left side pump
panel and labeled "Master Drain".

WATEROUS PUMP LUBRICATION SYSTEM 
An internal lubrication system shall deliver lubricant directly to the drive chain. This unique design shall
eliminate the need for an external lubrication pump and auxiliary cooling. Oil shall be supplied with the
lubrication system.

PUMP AND ENGINE COOLING SYSTEM
There shall be a pump and engine cooling system provided on the apparatus. The cooling system shall
keep the engine cool when running for long periords of time and the pump cool during long periods of
pumping when water is not being discharged. The cooling system shall also be setup in a way that the
cooling system lines can be easily drained through the master pump drain.

The cooling system lines shall consist of high-pressure, high-temperature 3/8" (inside diameter) abraded
rubber hose. The engine cooling lines shall be installed with one (1) line going from the discharge side of
the water pump through a Class 1, model 38BV, quarter turn ball valve and continuing on to the chassis
heat exchanger. The return line from the heat exchanger shall then run into the suction side of the pump.
The pump cooling lines shall be installed with one (1) line going from the discharge side of the water
pump through a Class 1, model 38BV, quarter-turn ball valve up to the water tank. At the water tank, the
pump cooling line shall be plumbed into a 3/8" check valve on the "Tank Fill" valve. The check valve shall
prevent tank water from back flowing into the pump when the cooling system is not in use. A return line
from the water tank shall be plumbed into the water pump.

The engine cooling system valve shall be controlled on the operators panel, and shall be clearly labeled,
"Engine Cooler".

The pump cooling system valve shall be controlled on operators panel, and shall be clearly labeled,
"Pump Cooler".

PUMP COOLER LINE
There shall be a 1/2" pump cooler line installed from the discharge side of the pump to the water tank.
The line shall be used to cool the pump during long periods of pumping when water is not being
discharged. The pump cooler shall be controlled with a quarter-turn ball valve on operators panel, and
shall be clearly labeled "Pump Cooler".

PUMP COOLER CHECK VALVE 
There shall be a check valve installed in the pump cooler line to prevent tank water from back flowing into
the pump when it is not in use.

ENGINEERING FOR FUTURE FOAM SYSTEM 
The stainless manifold on the pump shall be engineered for the future installation of a future foam system.
In addition to the plumbing, the pump operators control panel shall also be engineered for installation of
