SOLUTION PUMP–
The solution pump (fig. 4.31-4) is a centrifugal type hydraulic pump that is con-
trolled by the Pulse Width Modulated Valve (fig. 4.31-5) and the Raven console (fig. 4.31-6). 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 is also used for the agitation
system and the rinse sys-
tem.
