TeeJet MT600 Piston Injection Pump
The MT600 Injection Pump is a product designed for use in agricultural applications. It is used to pump chemicals or fertilizers into a spray system to be dispensed onto crops. The pump has a flow capacity that is determined by the size of the pump tube, which can be selected using the Pump Tube Selection Chart. Proper installation, mounting, and calibration are necessary for the pump to function accurately.
Installation and Mounting
The pump should be mounted securely to eliminate vibration and possible damage to the connecting hoses and cables. Refer to Figure 2 for the dimensions of the pump. Plumbing and cabling should be done carefully, avoiding moving parts, excessive heat, and exposure to debris. The power cable should be connected to the vehicle battery, with the red lead (fused) attached to the positive post and the black lead to the negative post.
Proper Pump Size Selection
The flow capacity requirements of the pump can be determined using the following formula:
US Measurements:
Pump Capacity = Max. Boom Width x Max. Speed x Chemical Rate x (.00202)
(oz/Min) = (feet) x (mph) x (oz/acre) x (.00202)
Metric Measurements:
Pump Capacity = Max. Boom Width x Max. Speed x Chemical Rate x (.00167)
(l/Min) = (meters) x (kph) x (l/ha) x (.00167)
Check the Pump Tube Selection Chart (Figure 3) to verify the proper pump tube
size.
Calibration
The accuracy of product delivery by the MT600 pump is dependent on the pump being accurately calibrated. It is recommended that the pump be calibrated any time the following occurs:
- There is a change in chemical or fertilizer being used
- There is a change in the application rate
- There is a change in environmental conditions
It is critical to the accuracy of the pump calibration that a back-pressure of at least 10 psi (70 kPa) be applied against the discharge of the pump while calibrating. A diaphragm check valve or similar serves this purpose well. Failure to follow this instruction will result in inaccurate calibration numbers.

Mounting
The MT600 injection pump is recommended to be located as close as possible to
the point where chemicals are injected into the main boom supply line (as
close to the delivery point as possible is the preferred injection point). A
consideration should be made to use check valves between the injection pump
and injection point as well as ahead of the injection point in the main flow
line (refer to the plumbing diagrams on Pages 6 and 7). The location of the
chemical container and the MT600 must also be considered and hose lengths kept
to a minimum.
Once the location for the injection pump is selected, orient the assembly so
that the pump cover is easily opened to allow access for service. All sides of
the pump may need to be accessible for service purposes. The pump must be
mounted in an upright position.
Five (5) US fluid ounces (150 ml) of SAE 10w30 oil must be added to each pump
head via the red cap port prior to operation. The top of the oil level should
always be visible somewhere in the viewing window. Avoid overfilling.
Figures 1 and 2 provide measurements and mounting holes for the pumps.

NOTE : Secure each pump firmly to eliminate vibration and possible damage to the connecting hoses and cables.
Plumbing
Refer to the sample plumbing diagrams on Pages 6 and 7 for suggestions on how
to connect the system.
Cabling
Each MT600 injection pump is equipped with two cables:
- a pump control cable
- a pump power cable.
Refer to the sample system diagrams on Pages 6 and 7 for suggestions on how to
connect the system.
Route all cables carefully. Avoid moving parts, excessive heat, and exposure
to tree limbs, stubble, and other debris. Allow enough slack at all pivot
points to prevent pinching or stretching the cables.
Secure the cables with cable fasteners and/or cable clamps.
Pump Power Cable
Route each power cable to the vehicle battery (12 VDC only). Attach the red lead (fused) to the positive post and the black lead to the negative post of the battery.
Proper Pump Size Selection
Use the following formula to determine the flow capacity requirements of the pump. Check the Pump Tube Selection Chart (Figure 3) to verify the proper pump tube size.
US Measurements:
Pump Capacity =| Max. Boom Width| x| Max. Speed| x| Chemical Rate| x|
(.00202)
---|---|---|---|---|---|---|---
(oz/Min) =| (feet)| x| (mph)| x| (oz/acre)| x| (.00202)
Metric Measurements
Pump Capacity =| Max. Boom Width| x| Max. Speed| x| Chemical Rate| x|
(.00167)
---|---|---|---|---|---|---|---
(l/Min) =| (meters)| x| (kph)| x| (l/ha)| x| (.00167)
US example: A sprayer with 35 feet booms traveling at a speed of 7 mph and
applying 32 oz of chemicals per acre requires a maximum pump capacity of 15.8
oz/min. (35 feet x 7 mph x 32 oz/ac x .00202 = 15.8 oz/min.) Referring to the
Pump Tube Selection Chart, a 3/16-inch pump is sufficient for this rate. If
100 oz/acre of chemical is required for application, a 1/4 inch pump tube is
required (35 feet x 7 mph x 100 oz/acre x .00202 = 49.49 oz/min) which exceeds
the recommended range of the smaller 3/16 inch tube. (Chart is in oz/min or
l/min)

NOTE: It is critical to the accuracy of the pump calibration that back-
pressure of at least 10 psi (70 kPa) be applied against the discharge of the
pump while calibrating. A diaphragm check valve or similar serves this purpose
well. Failure to follow this instruction will result in inaccurate calibration
numbers.
The accuracy of product delivery by the MT600 pump is dependent on the pump
being accurately calibrated. It is recommended that the pump be calibrated any
time the following occurs:
- The first time a pump is installed and used
- Any time a pump tube is changed
- Any time a new chemical is used in the pump
- Any time the operator feels that the pump discharge may not be accurate
If the calibration procedure ever results in a calibration number that does not fall within a range of +/- 10% of the above-stated default calibration numbers, the user must stop using the pump immediately and contact their TeeJet Technologies supplier for assistance.
Pump Tube Installation
To install the pump tube, release the tube retaining strap and lift it up and away from the tube rollers. Coat the tube with Tube Lube (included with tube) THIS IS A REQUIRED STEP. Attach one hose quick disconnect fitting to the left hose connection. Loop the tube over the rollers and down between the tube rollers and the tube strap hinge (there is not enough space between the tube roller assembly and the tube strap hinge to slip the tube in from the front without damaging the tube). Stretch the tube enough to lock the right hose quick disconnect the fitting into place. To prevent air leaks in the chemical lines, ensure that the gasket does not fall out or get twisted and that both fittings are tightened. Swivel the tube retaining strap into place and secure it with the latch.
Calibration
Refer to the 026-73 AddFlo User Manual.

Maintenance
TeeJet Technologies recommends the following maintenance to keep the MT600 injection pump operating at peak efficiency:
Flushing and Cleaning
Always refer to the Adjuvants manufacturer’s directions regarding cleaning and flushing. Check the pump head oil level. The top of the oil level should always be visible somewhere in the viewing window. Do not leave Adjuvants in the pump or application lines overnight. The system should be flushed and cleaned out thoroughly at the end of each day’s operation.
Weekly and Seasonal Pump Maintenance
Check the pump carefully for wear each week during frequent operations. Check
for cracking, belt wear, or other signs of material fatigue. If any signs of
deterioration are visible, replace the part immediately. Contact your TeeJet
dealer for assistance.
Install the ball and seat repair kit (Part number 54-02031) as illustrated in
Figure 6. The pump calibration must be checked at the beginning of each season
and periodically throughout the year. The pump calibration must be checked any
time a pump tube is changed.
Electric Power Supply| 12 Volts DC < 15 Amps @ Max RPM
Pump Type| Positive Displacement Piston
Dimensions| 25.4 mm x 29.1 mm x 40.5 mm
Fluid Output| 0.015 to 7 L/min (one to four head)
Plumbing points of attention
Depending on the sprayer it is recommended to adjust the plumbing to prevent the tank mix with Adjuvants to return to the main carrier tank. The moment the spraying stops:
- The carrier from the main tank (without Adjuvants) has to recirculate back to the tank and
- The liquid containing Adjuvants stays recirculating in the boom
Electrical points of attention
In case of retrofitting an existing AddFlow installation, make sure to replace
the existing Y-cable with cables 198-332 and 197-259.
In case of connecting an injection logging system logger, please review the
corresponding manual of the logger.
