D. SPRAY SYSTEMS
SOLUTION TANK–
You have the option of the poly tank
(fig. 4.29-1, item 1) or the stainless steel tank (fig. 4.29-1, item
2), both are 1000 gallon capacity. Their functions are similar,
the only notable difference being the plumbing of the tanks.
The poly tank has an eductor type agitation system and the
stainless steel tank has a sparge type agitation system.

SOLUTION FILL VALVE–
The solution tank valve (fig. 4.29-2,
item 1) is a ball type valve that is has to be opened and closed manually.
It allows solution into the tank when it is open. The valve needs to be
closed once filling is complete. The valve is controlled from inside the cab
with the TANK VALVE switch (fig. 4.29-3) located on the right hand con-
sole.
SOLUTION PUMP VALVE–
The solution pump valve (fig. 4.29-2,
item 2) is a ball type valve that has to be turned on and off manually. This valve is to allows the fluid from the
solution tank to flow to the solution pump.
RINSE TANK VALVE
–
The rinse tank valve (not shown) will allow fresh water to flow from the rinse
tank through the solution pump and lines. This does not allow for the rinse of the solution tank. The solution
pump valve must be closed to prevent contamination while rinsing.
FIG 4.29-2
SOLUTION PUMP–
The solution pump (fig. 4.29-4) is a diaphragm type semi-hydraulic pump that is
controlled by the Pulse Width Modulated Valve (fig. 4.29-5) and the Raven console (fig. 4.29-6). The pump
draws the solution out of the tank at a rate determined during the calibration of the Raven console. It dis-
penses it through the many valves and hoses that make up the spray system. The pump also dispenses fluids
through the agitation system and the rinse systems.
