C.6.2. INJECTION PUMP LOCATION
Injection pumps must be located as close as possible to the point where the chemicals will be injected into the main
boom supply line. Consideration for the location of the chemical containers must also be given, keeping the distance
from the injection pump to the chemical container to a minimum. There are two recommended locations for injecting the
chemicals into the carrier fluid.
A. Preferred Location: The inlet point of the main pump is the preferred location. This allows for excellent mixing
of the chemicals through the main pump. If this location is selected the sprayer must be plumbed so that no
mixed material can return to the main tank (See plumbing diagram in Appendix A). If sparging is necessary,
MID-TECH recommends installing a separate sparging pump. This has the added advantage of maintaining a
constant sparge flow, regardless of variations in ground speed or spraying rates.
B. Alternate Location: If sparge line agitation of the main tank is required, the injection point needs to be located
between the sparge line and the boom section valves. This can be accomplished by using an Auxiliary pump to
inject the metered chemicals from the Peristaltic Injection pumps into the relatively high pressure main boom
supply line.
C.6.3. CLEARANCE AND MOUNTING OF INJECTION PUMPS
Once the best location for the injection pump has been selected, plan to orient the assembly so that the injection pump
assembly cover is easily opened, allowing access for inspecting and changing the tubes. Be sure that the injection pump
assembly is protected from inadvertently being stepped on or bumped. Use the pump mounting base as a template to
mark the mounting hole locations. NOTE: Secure each pump firmly to eliminate vibration and possible damage to
the connecting hoses and cables.
C.6.4. INJECTION PUMP CABLE ROUTING
Each injection pump comes with two cables, one pump control cable and one pump power cable. NOTE: Route all
cables carefully, avoiding moving parts, excessive heat and exposure to tree limbs, stubble, or other debris. Allow
enough slack at all pivot points to guard against pinching or stretching the cables. Finally, secure the cables in place
with tie wraps and/or cable clamps.
Pump Control Cables: The operator needs to decide which pumps are to be designated #1 , #2, etc., and then mark the
cable tags accordingly, (use a permanent ink - water proof marker). Carefully route the cable to the console and connect
to the corresponding console connector. (See Appendix A)
Pump Power Cable: Route each power cable to the vehicle battery (12 VDC only) and attach the red lead (fused) to the
positive post and the black lead to the negative post of the battery.
NOTE: Since tank mixing is no longer required with this system, most
sprayers will not need a sparge line. MIDWEST TECHNOLOGIES recom-
mends that sprayers equipped with a sparge line (Main tank agitation return
line) be plumbed as a pump recirculating only sprayer, when a TASC
injection system is installed.
NOTE: Select the pump with a maximum capacity the next size larger than the
calculated capacity required. This will insure that the TASC system will have
enough capacity to provide precise control over the expected range of operating
conditions.
