3.3 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.
3.4 Safety
The ATP can produce high rod loads. All CheckPoint pump heads used with the ATP have been designed to
eliminate pinch points
3.4.1 For safe and continuous operation, locate the pump with supplied base on a stable and level surface
with sufficient access for the operator.
3.4.2 CheckPoint ATP requires horizontal mounting. Improper mounting could result in poor drive
performance and difficulty during priming. The ATP base is provided to ensure proper orientation.
3.4.3 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.

3.6 Connect chemical and process lines.
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 High Pressure Seal and other pump components.
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
high pressure seal failure. CheckPoint offers a range of chemical filters suitable for use with
the ATP pump.
3.6.1 Suction Check
The attach point is a ¼” MNPT thread. Apply thread sealant, taking care to keep the sealant away from the
inlet port. Sealant entering the check could cause the pump to operate incorrectly.
3.6.2 Discharge Check
The attach point is a ¼” MNPT thread. Apply thread sealant, taking care to keep the sealant away from the
discharge port. Sealant entering the process line could cause issues downstream.
4. MOTOR INSTALLATION
The base model 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.
4.1 Motor Requirements
4.1.1 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 ATP installation is equipped with an easily accessible “emergency off”
switch.

5. INJECTION HEAD ASSEMBLY
The base-level ATP pump assembly comes with a single head attached to the drive assembly (shown in
Figure 2).
5.1 Installing the Injection Head Assembly
To install the injection head assembly, follow the instructions below:
1. Screw in the head bolts until the hex heads are approximately ½” from the injection head.
2. Carefully align head assembly onto plunger and corresponding bolt holes in the housing.
3. Gently push the injection head assembly until the bolt heads fully pass through the housing and the
injection head assembly is seated against the housing.
4. Turn the injection head assembly clockwise until it stops. The check valves will be vertical when
properly installed.
5. If the injection head assembly cannot be turned all the way, loosen the head bolts 1-2 turns and
repeat step 4.
6. Tighten the head bolts to 45 in-lbs. Do not over tighten.

6. STROKE LENGTH ADJUSTMENT
Both injection heads operate independently and have adjustable stroke lengths between 0” - 0.75”.
6.1 Adjusting the stroke length
Pump Delivery Volume is controlled by adjusting the stroke length. To change the stroke length, the
adjustment screw is rotated clockwise for shorter stroke length or counterclockwise for longer stroke
length. The adjustment scale on top has indicators for approximate percentage of stroke. Note: These
values are only approximate. Depending on plunger size the zero point may vary slightly.
Max. stroke length ( ¾”)– Line up the adjustment indicator to the 100% marking for max stroke length
Min. stroke length (0”) - Line up the adjustment indicator to the 0% marking for minimum stroke length
