1. SYSTEM REQUIREMENTS
1.1 Inspection
1.1.1 Before installation, please inspect the pump carefully. If the pump appears to have sustained damage in
transit, call your CheckPoint Authorized Distributor or CheckPoint Customer Service directly at [phone]
to report and confirm damage. If it is determined that damage occurred in transit, a carrier claim will be required.
1.2 Storage
The Series ATP pump has been thoroughly tested at the CheckPoint factory prior to shipment. This testing may
leave residual fluids in the pump head. Although our pumps can be placed in service without environmental
protection, we suggest that they are stored indoors until being commissioned.
1.3 Unpacking
The ATP pump can be shipped as a single-head or dual-head pump. Please ensure that unpackaged pumps are
securely placed in a safe area. Refer to the CheckPoint Quick Setup Guide for installation of the ATP pump.
1.4 Safety
The Series ATP can produce high rod loads. All CheckPoint pump heads used with the ATP are designed to
provide cover plates to minimize pinch points. Use of the ATP with another brand of pump head is not
recommended and may present safety hazards.
1.5 Location
1.5.1 For safe and continuous operation, locate the pump with supplied base on a stable surface with sufficient
access for the operator.
1.5.2 CheckPoint requires horizontal mounting for the Series ATP. Improper mounting could result in poor drive
performance and difficulty during priming. The Series ATP base is provided to ensure proper orientation.
1.5.3 The pump may be mounted to a skid or other surface in a number of ways; however, clamping around the
outside of the drive is not recommended. Proper mounting techniques increase accessibility during maintenance
and troubleshooting.

1.7 Connect chemical and process lines to checks
Always clean suction lines and check chemical containers to ensure that they are free of all foreign matter, sand,
sludge, or chemical buildup.
NOTE: Even new chemical tanks can contain debris, which may cause system damage. Removing foreign
debris from suction lines and chemical containers will substantially extend the life of the packing
and other pump components.

CP-MAN-PRD-ATP REV00 EFF. DATE 04/01/19Page 5 of 12
NOTE: A presuction in-line chemical filter is strongly recommended to prevent early packing failure.
Abrasive particles carried into the pump through suction plumbing is a common cause of packing
failure. CheckPoint offers a range of chemical filters suitable for use with the Series ATP pump.
1.7.1 Suction Check
The attach point is a ¼” MNPT thread. Apply thread sealant, taking care to keep the sealant away from the suction
inlet port. Sealant entering the check could cause the pump to operate incorrectly.
1.7.2 Discharge Check
The attach point is a ¼” FNPT thread. Apply thread sealant, taking care to keep the sealant away from the process
line port. Sealant entering the process line could cause issues downstream.
2. MOTOR INSTALLATION
The base model Series ATP comes with the motor already installed. Should you need to remove the motor for any
reason, install per the motor install drawing located on the CP website.
Installation is made easier (though not required) using CheckPoint’s installation tool, available for purchase (insert
part # here).
2.1 Motor Requirements
2.1.1 The Series ATP drive input accepts a male a 5/8” shaft.
•CheckPoint recommends a motor/gear reducer combination not exceeding 120 rpm at the ATP drive input
shaft. The maximum-rated rotational speed of the ATP input shaft is 120 rpm. NEVER EXCEED 120 RPM.
2.1.2 Connect Power
•Special attention should be paid to motor type and location hazards prior to hookup. The electric motor
must be connected in accordance with all local regulations and area classifications and should include
overload protection.
•It is recommended that the Series ATP installation is equipped with an easily accessible “emergency off”
switch.

3. INJECTION HEAD ASSEMBLY
The base-level Series ATP pump assembly comes with a single head attached to the drive assembly (shown in
Figure 2).

3.1 Adding an Injection Head.
The base model Series ATP comes with a single head but can be easily converted to a double-headed
configuration. You will need the following assemblies:
Figure 3: Head Assembly - Typical Figure 4: Retainer Assembly –All Models
3.1.1 Install the retainer assembly (clamp screw towards the front cover) to the carriage assembly using (2) attach
screws.

3.1.2 Install plunger, snap ring, and screw assembly.
•Loosen the clamp screw approximately ½-turn.
•Screw the adjusting nut into the retainer assembly.
NOTE: The adjusting nut screwed in until it bottoms out on the end plate is full-stroke.

3.1.3 Attach head assembly
•Remove the two head bolts and install the thru drive housing wall.
•Add the approved grease on the tip of the plunger.
•Slide the head assembly over the plunger and tighten the head bolts to 20 in-lbs.
FIGURE 7: HEAD ASSEMBLY ATTACHMENT
4. STROKE LENGTH ADJUSTMENT
Both injection heads operate independently and have adjustable stroke lengths between 0” - 0.75”.
4.1 Adjusting the stroke length
Pump Delivery Volume is controlled by adjusting the stroke length. To change the stroke length, the adjusting nut
in the retainer assembly is screwed in or out depending upon the volume required. The retainer assembly block
has indicators for approximate percentage of stroke.
Max. stroke length ( ¾”)- Adjusting nut should be screwed in until it bottoms out on the end plate of the
carriage. Do not over-tighten nut.
Min. stroke length (0”) - Adjusting nut should be unscrewed until the bottom of adjusting nut is at the 0% mark.

CP-MAN-PRD-ATP REV00 EFF. DATE 04/01/19Page 10 of 12
Adjust the stroke as directed below in Figures 8 and 9.
1. Turn off the drive system
2. Remove the front cover
3. Loosen the clamp screw ½-turn (or as required)
4. Insert the tool into the 3/16” adjusting nut hole
5. Rotate the adjusting nut to the desired stroke length (clockwise to increase stroke)
6. Restart the drive system
7. Check the flow rate
8. Once the desired flow is achieved, tighten the clamp screw.
NOTE: Very little clamping force is required to lock adjusting nut. Do not overtighten.
FIGURE 8: SHOWN AT 100% STROKE FIGURE 9: SHOWN AT 50% STROKE
5. OPERATION
The CheckPoint Series ATP drive requires no additional lubrication. The cam bearing is sealed, and the guide rods
have sufficient grease in the carriage assembly prior to shipment.
Pump Flow Rate –DC Motor
•The flow rate can be adjusted by changing the motor rpm and by changing the stroke length.
NOTE: Adjusting the motor’s rpm during operation will not damage the Series ATP pump. Refer to your
motor manufacturer’s manual to determine the effects of adjusting RPM during operation.
Pump Flow Rate –AC Motor
•The flow rate can be only adjusted by changing the stroke length.

5.1 Initial Startup
5.1.1 Ensure that no leaks are visible prior to startup.
5.1.2 Disconnect the power to the motor.
5.1.3 Remove the outer cover to gain access to the plunger adjustment screw.
NOTE: The pump was tested in-house prior to shipping, using water with 5% water-based lubricant. If the
residual liquid remaining in the pump from testing could cause issues with the chemical, flush the
head prior to use.
WARNING: PINCH POINTS EXIST INSIDE THE BOX. DISCONNECT POWER BEFORE REMOVING COVER.
5.1.4 Open the chemical supply and system pressure valves.
5.1.5 Start the motor.
5.1.6 Bleed the injection head.
5.1.7 Adjust the flow rate.
6. TROUBLESHOOTING
6.1 Pump does not stroke
6.1.1 Check the power to the motor.
6.1.2 Ensure that the required amount of power is supplied to the motor and that the motor is turned on.
6.1.3 Check to see if the motor power is too low.
6.1.4 Ensure proper motor sizing for the particular application. Contact CheckPoint or your Authorized CheckPoint
Distributor for sizing assistance.
6.1.5 Check to see if there is damage to the keyway.
6.1.6 A key may have sheared during an overload situation. Inspect all bores and keyways for damage or missing
components.
6.2 Drive is excessively noisy
6.2.1 Drive components may be worn.
6.2.2 The motor or gear reducer may be worn. Contact your drive component manufacturer.
