Operating Manual
CP/MAN-PRD-1215E REV. 02 EFF. DATE: 12/15/12 Page 3 of 13
CAUTION: DO NOT OPERATE PUMP WITHOUT READING ALL OF THE FOLLOWING
INFORMATION!
This manual covers the installation and operation of CheckPoint Electric motor-driven pumps fitted with Series
1250/1500 chemical heads and CheckPoint stroke-adjustable type E gearboxes.
1. PUMP DATA
1.1. All information specific to the pump unit shipped with these instructions is contained in the PUMP
DATASHEET attached to this Manual.
1.2. Refer to Figure 5 on the last page of this Manual for location of referred components of this pump.
2. PUMP INSTALLATION
2.1. Prior to installing your injector, please inspect the pump carefully for any possible in-transit
damage. If the pump appears damaged, call your authorized CheckPoint distributor or call
CheckPoint customer service directly at (800) 847-7867 or (504) 340-0770 to confirm damaged
condition. If we determine that damage has occurred in transit, you will need to file a claim with the
carrier.
FIGURE 1
2.2. Ensure that all necessary components are present in your injection system and in good working
order. CheckPoint is available to answer your process questions or to help design and build a skid
system utilizing components appropriate for your application.
CAUTION: THE PUMP MUST ALWAYS BE ORIENTED WITH THE SUCTION CHECK VALVE
FACING DIRECTLY DOWN. MOUNTING THE PUMP IN ANOTHER ORIENTATION
MAY CAUSE CHEMICAL LEAKAGE TO COLLECT IN AN UNDESIRED LOCATION
OR CAUSE OTHER PROBLEMS.

Operating Manual
CP/MAN-PRD-1215E REV. 02 EFF. DATE: 12/15/12 Page 4 of 13
2.3. CheckPoint recommends use of a calibration gauge for your assurance of proper pump function
and chemical delivery rate. Refer to Section 11: Setting and Adjusting the Pump Delivery Volume
on page 8 for more information. The proper position of the calibration gauge (labeled #5) is shown
in Figure 1.
CAUTION: IT IS NECESSARY TO ATTACH A VENT TUBE TO THE TOP OF ALL
CALIBRATION GAUGES, CHEMICAL TANKS, AND TANK LEVEL GAUGES. THE
HEIGHT OF THE TOP OF EACH VENT TUBE SHOULD ALWAYS BE GREATER
THAN THE HIGHEST POSSIBLE LIQUID LEVEL IN THE SYSTEM, AND THE TUBE
SHOULD HAVE MEANS TO PREVENT WATER ENTRY, SUCH AS A 180 DEGREE
BEND.
2.4. This pump does not require flooded suction or positive chemical pressure to prime, and can
therefore be mounted above the chemical container. For a chemical with water-like viscosity, the
pump will pull air out of the chemical line and prime from up to twelve feet above the liquid level in
the tank. This feature is dependent upon proper packing adjustment and adherence to all points
made in Section 2.5 below.
2.5. All valves, fittings, and piping between the source of chemical and the pump’s suction check valve
must be 100% bubble-tight and fully compatible with the chemical being delivered and with each
other. Failure to adhere strictly to this rule will lead to gas build-up in the chemical head and loss
of prime. specifically:
2.5.1. Any fitting or screw-on joint without Teflon™ tape or other acceptable joint sealant may allow
air at atmospheric pressure to enter the suction tubing, even if no chemical leakage is
visible.
2.5.2. Dissimilar metals, when joined together in the suction pipe work may react with each other,
creating gas bubbles that will end up being carried into the pump head. CheckPoint
generally recommends all suction components, including all tubing, piping, fittings, and
valves, be of similar material, preferably stainless steel or other chemically resistant metal.
2.5.3. Incompatibilities between the chemical and the metallic elements in the suction pipe work
can also create such gas bubbles. In particular, some acids require Hastelloy™ or PVC
fittings and tubing, while other chemicals may only require 316 SS.
2.6. Always check to ensure that all process block valves are closed prior to disconnecting or reinstalling any chemical injection pump. There should always be a block valve placed between a
properly installed pump and the process flow and the chemical supply. Conversely, while the
pump is running, all such block valves should always be open.
2.7. To ensure sufficient flow rates of chemical and minimize pressure drop through the lines, all
suction lines should be at least 3/8 inches diameter and all discharge lines should be at least ¼
inch diameter. Multiple pump installations and for viscous chemicals require additional allowances.
Contact CheckPoint or your authorized CheckPoint distributor for design assistance.
2.8. Pulsation dampeners are sometimes specified in systems utilizing low-flow 1250/1500 Series
CheckPoint pumps. CheckPoint does not recommend their use because the low flow rates of all
1250/1500 Series pumps do not generate harmful pulsation.

3. PRIOR TO STARTUP – SAFETY CHECKS
3.1. Is the gearbox filled with suitable lubricant?
3.2. Is the power supply correctly matched to the motor?
3.3. Is the electric hookup of the pump correct and carried out according to all applicable codes?
3.4. Are all tubing/pipe connections made up correctly?
3.5. Is there a pressure relief valve on the discharge side?
3.6. Is the pressure relief valve operating correctly and is it set to the correct pressure?
4. CHECKING THE GEAR LUBRICANT LEVEL
CAUTION: THE PUMP GEARBOX MUST BE FILLED WITH GEAR LUBRICANT AT ALL TIMES
WHEN OPERATING THE PUMP TO AVOID RISK OF DAMAGE AND
OVERHEATING.
4.1. Oil level should be checked weekly.
4.2. Use the Gear Oil Level Dipstick/Fill Plug (Item 10 in Figure 5 at the end of this Manual) to check
the level of lubricant as follows:
FIGURE 2
4.2.1. Stop pump and wait for approximately 5 minutes.
4.2.2. Unscrew cap, wipe dipstick with clean rag.
4.2.3. Put dipstick into hole, but do not screw it back in.
4.2.4. Oil level should be between the end of the dipstick and the middle of the groove.
4.2.5. Replace cap by screwing back in snugly.
5. GEAR LUBRICANT TYPE
5.1. Oil type for refilling and adding may be either synthetic or
mineral, but never both at the same time.
CAUTION: NEVER MIX SYNTHETIC AND MINERAL OIL IN
THE GEARBOX!
5.2. Mineral oil must conform to CLP 220 or ISO – L – CKC
220. Shell Omala 220, Mobil Gear 630, and Exxon
Spartan EP 220 are examples of mineral oils that are
acceptable.
5.3. Synthetic oil must conform to CLP PG 220 or ISO – L – CKS 220.
5.4. Mineral oil should be changed after each 4000 hours of use or one year of operation.
5.5. Synthetic oil should be changed after each 8000 hours of use or two years of operation.

5.6. Capacity of unit is 0.65 liters.
CAUTION: DANGER OF BURNS WHEN DRAINING HOT LUBRICANT!
CAUTION: ASSURE ENVIRONMENTALLY SAFE DRAINING AND DISPOSAL OF SPENT
LUBRICANTS.
6. RELIEF VALVE
CAUTION: NEVER OPERATE PUMP WITHOUT A PRESSURE RELIEF VALVE ON THE
DISCHARGE SIDE OF THE PUMP THAT HAS BEEN SET TO THE APPROPRIATE
OVERLOAD PRESSURE! DOING SO MAY CAUSE DAMAGE TO THE GEARBOX
AND/OR CAUSE A LEAK HAZARD!
CAUTION: WHEN USING A PRESSURE RELIEF VALVE, CHEMICAL TANK OR VESSEL MUST
BE PROPERLY VENTED TO ATMOSPHERE TO AVOID THE POSSIBILITY OF
OVER-PRESSURIZING THE TANK IF THE PRESSURE RELIEF VALVE OPENS!
6.1. A discharge pressure relief valve has been supplied with the pump when shipped from
CheckPoint. It has been set to the appropriate discharge overload pressure at the factory.
6.2. Overload pressures are as given in Figure 3 according to plunger diameter:

7. MOTOR ELECTRICAL CONNECTION
7.1. The electric motor must be connected so that its direction of rotation is the same as the arrow on
the gearbox.
7.2. The electric motor must be connected in accordance with all local regulations, including especially
overload protection.
7.3. The complete installation must be equipped with an “emergency off” switch that is easily and
quickly accessible by the user.
8. CONNECTING THE CHEMICAL SUPPLY
8.1. Clean suction lines and check chemical containers to ensure that they are free of all foreign
matter, sand, sludge, or chemical buildup.

CP/MAN-PRD-1215E REV. 02 EFF. DATE: 12/15/12 Page 7 of 13
CAUTION: REMOVING FOREIGN DEBRIS FROM SUCTION LINES AND CHEMICAL
CONTAINERS WILL SUBSTANTIALLY EXTEND THE LIFE OF THE PACKING AND
OTHER COMPONENTS OF THE PUMP. EVEN A NEW CHEMICAL TANK CAN
CONTAIN DEBRIS THAT CAN BE CARRIED INTO THE PUMP AND DAMAGE IT.
NOTE: If premature scoring of the pump plunger or early packing failure is observed during
operation, a likely cause is abrasive particles carried into the pump through the
suction plumbing. Use of a pre-suction in-line chemical filter such as the CheckPoint
F40 Series and/or a ceramic or Hastelloy™ plunger is recommended.
CAUTION: SUBSTANTIAL SCORING OF THE PLUNGER CAN LEAD TO SEVERE LEAKAGE
OF CHEMICAL INTO THE ENVIRONMENT.
8.1.1. Connect the chemical suction line to the suction check valve on the pump head. The suction
check valve has a 1/4” NPT male thread (for Series 1250 heads) or a ½” NPT male thread
(for Series 1500 heads), with an arrow indicating chemical flow direction towards the pump
(see Figure 5 at the end of this Manual).
NOTE: Always apply Teflon™ tape or other appropriate thread sealant to the check valve
threads prior to attachment to prevent leakage.
CAUTION: NEVER RE-LOCATE THE SUCTION OR DISCHARGE CHECK VALVES AWAY
FROM THE CHEMICAL HEAD. TO OPERATE PROPERLY, CHECK VALVES MUST
REMAIN DIRECTLY ATTACHED TO THE CHEMICAL HEAD. IF DESIRED, A
SECONDARY DISCHARGE CHECK MAY BE PLACED DOWNSTREAM OF THE
PRIMARY DISCHARGE CHECK VALVE.
8.2. Connect your discharge line to the discharge check valve. This is a 1/4” NPT male thread on the
Series 1250 head and ½” NPT male thread on the Series 1500 head. An arrow is stamped on the
discharge check valve pointing away from the pump.
8.3. Check that the packing nut is properly adjusted. In a new pump, proper adjustment is finger-tight,
plus 1/8 of a turn. Use a packing adjustment tool (available from CheckPoint at no charge) for best
results. IMPORTANT: PLEASE REVIEW Section 11: Packing Adjustment.
CAUTION: DO NOT OVER-TIGHTEN THE PACKING NUT. APPLYING EXCESS TORQUE TO
THE PACKING NUT WILL DECREASE THE LIFE OF THE PACKING.
8.4. Open the process block valve, allowing the process pressure to reach the chemical head. Correct
any leakage observed.
9. BLEEDING/PRIMING THE PUMP
9.1. The bleed screw is fitted with a 1/8” NPT female connector to allow the user to tube chemical used
in the bleeding process to a safe area.
9.2. Prior to bleeding air from the pump head, check to ensure that the packing nut is properly
adjusted. Before attempting to adjust or tighten the packing nut, please read Section 11: Packing
Adjustment. It is important not to over-tighten the packing nut.
1250E & 1500E Electric Pump
Operating Manual
CP/MAN-PRD-1215E REV. 02 EFF. DATE: 12/15/12 Page 8 of 13
9.3. Open the chemical supply block valve.
9.4. Open the process block valve.
CAUTION: OTHER THAN DURING BRIEF TESTING, NEVER OPERATE THE PUMP WITHOUT
CHEMICAL SUPPLY AVAILABLE AND FLOWING FREELY. DOING SO WILL
CREATE UNDUE FRICTION AND HEAT, DECREASING THE LIFE OF THE
PACKING, HASTENING CHEMICAL LEAKAGE, AND VOIDING THE PUMP
WARRANTY.
9.5. Start the pump.
9.6. Adjust the stroke length to maximum.
9.7. Open the bleed screw 1 1/2 to 2 turns. The pump will begin to pull air and chemical through the
chemical supply plumbing, into the head, and out the port in the bleed valve. Leave the valve open
until a solid stream of chemical pumps out the bleed port with each stroke of the pump.
NOTE: If the pump is not new, it is very possible for dried or solidified chemical to be present
in the bleed assembly. If your pump does not bleed when following the directions
above, try cleaning these items in solvent and replacing them.
9.8. Close the bleed screw until chemical flow through the bleed port stops.
CAUTION: DO NOT OVER-TIGHTEN THE BLEED SCREW. TIGHTEN THE BLEED SCREW
ONLY UNTIL CHEMICAL STOPS FLOWING. APPLYING EXCESS TORQUE TO THE
BLEED VALVE MAY IMPAIR FUTURE VALVE OPERATION.
NOTE: Occasionally, soon after closing the bleed assembly, you may observe packing
leakage. If so, this is usually due to a loose packing nut. Adjust the packing nut per
the instructions in Section 11: Packing Adjustment.
9.9. Adjust the stroke length to obtain proper delivery volume per directions in Section 10 below.
10. SETTING AND ADJUSTING THE PUMP DELIVERY VOLUME
10.1. The pump stroke rate remains constant regardless of delivery volume.
10.2. The pump stroke rate is determined by the gear ratio of the gearbox and the motor speed in
revolutions per minute. To calculate the stroke rate of the pump, divide the motor speed on the
faceplate of the electric motor by the gear reduction factor of the gearbox. The gear reduction
factor is shown on the PUMP DATA SHEET.
10.3. The pump delivery volume is adjusted by changing the stroke length.
10.4. The large black dial (Item 8 on Figure 5 at the end of this Manual) is used to adjust the stroke
length of the pump.
10.5. Turning the knob adjusts the stroke length from a maximum of 15 mm (0.591 in) to a minimum of
no stroke at all.
10.6. Use the Adjustment Gauge (Item 9 on Figure 5 at the end of this Manual) on the side of the
vertical stem just underneath the black dial to determine the stroke length.

Operating Manual
CP/MAN-PRD-1215E REV. 02 EFF. DATE: 12/15/12 Page 9 of 13
10.7. The stroke length may be adjusted whether the pump is running or not.
10.8. There are a variety of calibration gauges available, including a complete line of appropriately-sized
CheckPoint calibration gauges for every CheckPoint pump. To ensure that your pump is working
as is should and that chemical is being delivered at the rate you need, it is important to use a
calibration gauge.
10.9. Most calibration gauges are designed to read properly when one full minute of pumping has taken
place. However, if the liquid level drops too fast to allow for a full minute, shorter periods are
acceptable. Try to size the gauge so that at least a 30 second test can be made, however, or a
loss of accuracy will result.
10.10. Proper gauge placement and plumbing is important. Please refer to Figure 1 for appropriate
valving and placement, and for reference numbers as used in this section. The calibration gauge
is labeled as #5.
10.11. With the pump either running or stopped, open the Gauge Fill Valve (shown as #4 in Figure 1).
The calibration gauge (#5) should begin to fill. Continue filling until the chemical level is at or near
the top markings on the gauge, then close the Gauge Fill Valve (#4).
10.12. Now ensure that the CheckPoint pump is running. Take note of the level of chemical in the gauge
using the appropriate scale for the volume units you want to measure the pump’s output in.
Usually the calibration gauge will show liters on one scale and quarts or gallons on the other. It is
best to write down the number so that you can calculate flow accurately.
10.13. Open the Gauge Fill Valve (#4), and immediately close the Chemical Supply Valve (#1). This
isolates the pump and gauge so that the pump is being supplied directly from the gauge.
10.14. The level in the gauge should begin to fall. When the liquid level in the gauge gets near the bottom
of the gauge, or when one minute has expired (whichever comes first), stop timing, note the
ending level on the gauge, and reopen the Chemical Supply Valve (#1).
10.15. Write down the amount of time in seconds and the final gauge reading, then close the Gauge Fill
Valve (#4).
NOTE: Failure to reopen the Chemical Supply Valve will result in the pump quickly depleting
the remaining chemical in the gauge and sucking in air from the gauge, necessitating
pump re-priming.
NOTE: In cases where the chemical flow rate is extremely low, you may need to time for
longer than one minute to allow an adequate amount of chemical to move out of the
gauge.
10.16. The pumping volume (in the units specified on the gauge scale) will be given by the following
equation:
PUMPING VOLUME =
[END READING] – [BEGINNING READING]
X 60
[DURATION OF READING IN SECONDS]
NOTE: To ensure accurate stroke rate measurement, allow sufficient measurement duration.
Where possible, allow at least thirty seconds of gauge drawdown.

11. PACKING ADJUSTMENT
11.1. Packing adjustment is usually indicated whenever adjustable packing is installed in the pump and
leakage can be observed around the packing nut or coming out of the weep hole drilled through
the packing nut. In most cases, if there is no leakage, no adjustment is necessary.
11.2. Use a CheckPoint T55-101 packing adjuster, which is specifically designed for this purpose. If one
is not available, you may order one at no charge directly from CheckPoint. In an emergency or if
time is short, a 6” length of ¼” OD tubing or metal rod may be used.
11.3. Packing should generally be adjusted while pump is running if it is already in service.
11.4. To tighten the packing, insert the tool into one of the six shallow radial holes in the packing nut
(Packing Nut is shown as #3 in Figure 5 at the end of this Manual), and tighten the nut clockwise
(when looking at the pump from above. Snug the nut until light pressure with one finger on the
packing nut tool no longer moves the packing nut.
11.5. From this point, TIGHTEN THE NUT 1/8 TURN ONLY as follows:
11.5.1. If adjusting the packing while pump is operating, pause after each 1/8 turn to determine if the
leakage has stopped, allowing for enough time to ensure previous leakage has already
drained from the nut weep holes and threads. If pump is still leaking, turn packing nut an
additional 1/8 turn and check again. Continue turning the nut 1/8 turn at a time as often as
necessary to stop the leakage. If the leakage cannot be stopped, or if excessive force is
required to stop leakage, it is time to replace the packing.
11.5.2. If adjusting the packing prior to new installation or when not currently running, tighten the nut
1/8 turn from the finger tight position.
1250E & 1500E Electric Pump
Operating Manual
CP/MAN-PRD-1215E REV. 02 EFF. DATE: 12/15/12 Page 11 of 13
NOTE: If the packing is being adjusted while the pump is running, the pump will typically not
stall no matter how much the packing nut is tightened. Care must thus be taken not to
apply too much pressure when adjusting the packing nut, as this will reduce packing
life.
12. PACKING REPLACEMENT
Follow the steps below to change the packing.
NOTE: The 1/8”, 1/4”, and 3/8” plunger sizes on the Series 1250 and the ½” and ¾” plunger
sizes on the Series 1500 require a metal adapter sleeve in the packing gland. When
removing the packing, this sleeve should also be removed and cleaned. It is important
to remember to re-install the sleeve.
NOTE: The 1/8” plunger size on the Series 1250 and the ½” and ¾” plunger sizes on the
Series 1500 require an O-ring and a backup ring. The 1/8” plunger size also requires
a snap ring.
NOTE: If your early model 1/8” Series 1250 does not have a sleeve that contains the packing
inside, and/or if it does not contain a backup ring, O-ring, and snap ring, please
contact CheckPoint to obtain the updated parts.
12.1. Shut off power to the pump.
12.2. Close the block valves on the chemical supply and discharge.
12.3. Disconnect the chemical supply from the pump at the suction check valve, and disconnect the
discharge line from the discharge check.
12.4. Remove the chemical head by removing the two head bolts and then separating the head
component from the body of the pump.
12.5. Unscrew and remove the packing nut, using 1/4” tubing or a packing nut tool. A packing nut tool is
available at no charge from CheckPoint. For all sizes other than 1/8”, proceed to step 12.7.
12.6. For 1/8” plunger model, remove the internal snap ring from its groove. It is located on top of the
sleeve just below where the internal packing nut threads end.
12.7. Remove the Inspection/Cleanout Plug from the head.
12.8. Using the access hole where the Inspection/Cleanout Plug was, push out the packing and sleeve
with a punch or screwdriver. For the 3/8” Series 1250 head, proceed to step 12.10. For ½” Series
1250 head and the 1” Series 1500 head, proceed to step 12.11.
12.9. Remove the packing from the sleeve, along with the O-ring and backup ring on the small outside
diameter of the sleeve. Clean the sleeve and lightly grease it, then install the new O-ring and
backup ring supplied with your new packing. If you cannot locate these parts, please contact
CheckPoint for replacements. Your 1/8” pump may leak chemical without replacing these
components whenever you replace the packing.
12.10. Replace the metal sleeve.
12.11. Examine the new set of packing closely and ensure, prior to installation, that it is oriented properly
according to Figure 4. Your packing will be similar to the cross sectional view shown.

FIGURE 4
NOTE: When replacing adjustable packing, always install the packing rings exactly as they
are shipped. Rearranging the order of the vee-rings in an adjustable packing set will
reduce the life of the elastomer ring in the packing set.
12.12. Grease the packing rings on their outside diameters lightly and install them, one ring at a time. It is
important to adhere to the ring order and orientation as shown in the diagram.
NOTE: On the 1/8” Series 1250 and the ½” and ¾” Series 1500, the packing fits inside the
sleeve rather than directly into the packing gland.
12.13. On the 1/8” plunger model, replace the internal snap ring to retain the sleeve.
12.14. Grease the packing nut threads and replace the nut loosely by hand.
12.15. Grease the plunger rod protruding from the pump motor.
12.16. Taking care to insert the plunger into the packing without damaging or bending it, replace the
chemical head onto the main body of the pump.
12.17. Grease the threads on the two head bolts, then insert and hand-tighten them.
12.18. Tighten the packing nut to the point where light pressure with one finger on the packing nut
adjuster will no longer move the packing nut.
12.19. Fully tighten down the head bolts. Failure to adhere to this procedure can lead to a misaligned
head and leaking packing.
12.20. Reattach all process lines to the chemical head, and open all isolation valves leading to the pump
chemical supply and discharge.
12.21. Adjust the packing nut per the directions in Section 11.
