SOLUTION TANK–
The GST 20 has a 2000 gallon
capacity stainless steel solution tank (fig. 4.52-1). The
stainless steel tank has a sparge type agitation system.
SOLUTION TANK VALVE–
The solution tank valve (fig. 4.52-2,
item 1) controls the amount of solution coming out of the tank. The valve
is controlled from inside the cab with the TANK VALVE switch (fig. 4.52-3)
located on the right hand console.
TANK SUMP VALVE–
The
tank sump valve (fig. 4.52-2, item
2) is a ball type valve that has to
be turned on and off manually.
This valve is to allow the fluid into the tank from the side fill.
FIG 4.52-3
SOLUTION PUMP–
The solution pump (fig. 4.52-4) is a centrifugal type hydraulic pump that is con-
trolled by the Pulse Width Modulated Valve (fig. 4.52-5) and the Raven console (fig. 4.52-6). The pump draws
the solution out of the tank at a rate determined during the calibration of the Raven console. It dispenses it
through the many valves
and hoses that make up
the spray system. The
pump also dispenses fluids
through the agitation sys-
tem and the rinse systems.
