Installation
It is important that the AC+ Dry Blender be installed within 3 feet (1 meter) of the liquid
source. The supply piping should be short with a minimum number of elbows and fittings
that impact flow of the liquid into the blending chamber. An eccentric reducer is
recommended at the liquid inlet of the blender. The need for future cleaning and
inspection should be considered when installing the blender.
A supply pump is required to feed the liquid to the blender. A discharge pump may also
be required for certain applications. Contact Ampco Pumps for supply and discharge
pump recommendations.
The adjustable legs should be installed to the base of the unit and the blender should be
positioned where the blending operation will take place. Use a wrench to adjust the legs,
one at a time, until the unit is level.
Connect the supply and discharge piping, making sure each is positioned correctly and
properly supported. Incorrect piping may result in strain on the blender casing. The
AC+2116 model has an 1 ½ inch (38.1mm) liquid inlet, 2 inch (50.8mm) powder inlet,
and 1 ½ inch (38.1mm) liquid outlet. The AC+3218 model has 1 ½ inch (38.1mm)
liquid inlet, 3 inch (76.2mm) powder inlet, and 2 inch (50.8mm) liquid outlet. The
AC+4329 model has a 2 inch (50.8mm) liquid inlet, 4 inch (101.6 mm) powder inlet, and
3 inch (76.2 mm) liquid outlet.
The purchaser is responsible for supplying and installing all piping. Liquid inlet
piping should be short and provide a direct route into the blender. There should be
a minimum number of elbows and fittings in the supply piping. Elbows in the liquid
inlet piping will produce increased friction in the line which will result in cavitation in
the blender casing. Cavitation will result in vibration, noise, poor performance, and
possible damage to the blender. It is recommended the pipe diameter at the inlet be
increased in size where possible. Using an eccentric tapered reducer in place of a
concentric reducer at the inlet will help direct the flow to minimize turbulence.
It is possible to order the blender with an electrically controlled Butterfly valve. The electric
valve should be wired to an auxiliary 110V power source. This will allow the valve to
operate separately from the blender motor so it may be closed if the motor fails. If the power
source to the Butterfly valve also fails, it should be possible to manually override the valve
by applying a wrench to the flats on the coupling adapter.

Operation
Reassembly
Models AC+2116 and AC+2116 System
1. Screw the adjustable legs into the base. On the 2116 System, use bolts to attach the base
to the dolly.
2. Mount the six spacers and the ring adapter to the base. Place the base on the top of the
motor. Mount the motor.
3. Loosely set the four motor mounting screws. Enough movement must be allowed to allow
alignment of the motor shaft in the back plate.
4. Slide the stub shaft down and over the motor shaft.
5. Place the casing gasket on the back plate. Slide the back plate over the stub shaft.
6. Place the impeller on the shaft. There should be approximately 1/16” clearance between
the back plate and impeller. The caps crews on the shaft collar may now be tightened
securely.
7. Remove the impeller and check the position of the stub shaft. If the stub shaft is not
centered in the back plate, move the motor until the stub shaft is centered. Securely
tighten the motor mount screws.
8. Install the balanced seal. Sealing of the process fluid along the shaft is accomplished by
action of the process pressure on an o-ring seal installed in a groove in the carbon seal.
The same action pressurizes the o-ring groove and augments the spring tension in keeping
a tight joint at the sealing faces. The width of the seal face controls the balancing of the
seal. This type of seal should be replaced when the clearance between the carbon seal
face and the back plate is less then 1/32: (0.79mm) or when leakage is noted. **See
instructions for setting the drive collar and seal replacement on page 13**
9. Again place the impeller back gasket and impeller on the stub shaft. Place the impeller nut
gasket on the impeller nut. Secure the impeller by tightening the impeller nut.
10. Place the screen to the notch on the inside of the casing. Check to see the screen fits
snugly and does not spin.
11. Set the casing on the back plate and clamp together with the large casing clamp.
12. Install the seal guard.
13. Install the inlet tube assembly with gaskets and clamps. Tighten clamps. Note: there is a
top and bottom to the inlet tube assembly. Place the assembly to be opposite the casing
outlet tube.
14. Install the diffuser and suction tube with the gaskets and clamps. Tighten securely.
15. Mount the control valve with gaskets and clamps. Tighten.
16. Mount the hopper to the top of the valve with gaskets and clamps. Tighten.
17. Connect supply and discharge piping.

Operation
Reassembly
Models AC+3218 and AC+4329
1. Place the o-ring into the deflector collar.
2. From the bottom, slide one bearing onto the shaft until it rests against the shoulder. The
AC+4329 model requires two bearings at the shoulder of the shaft.
3. Place the shaft in the bearing housing.
4. The other bearing should be installed on the shaft through the bottom of the bearing
housing.
5. Place the retaining ring on the bottom of the shaft.
6. The bearing housing should then be installed by placing it on top of the base and tightening
the bolts.
7. Place the deflector at the top of the bearing housing.
8. The retainer ring and spacers are set by first screwing the six spacers into the ring then
bolting the spacers onto the base plate.
9. If your blender has the DG seal, install the seal gland ring with gaskets and attach to the
back plate before installing the back plate.
10. Slide the back plate over the shaft, being careful to not damage the sealing surface. Place
the back plate onto the retainer ring.
11. Center the shaft by tightening the spacer bolts in a cross pattern. Once the shaft is
centered, remove the back plate.
12. To install the motor, the blender must be tipped back on its side. Tighten the motors bolts
so they touch the bottom of the base and can be used to adjust the tension on the belts.
13. To install the pulley system, start with the blender pulley, installing the pulley key, pulley,
and bushing. Tighten the bolts.
14. Next install the motor end of the pulley system. Install the motor pulley key, the pulley,
and the bushing. Tighten the bolts. Both pulleys should be aligned horizontally.
15. Use the mounting bolts to draw the motor pulley tight. Tighten the bolts a small amount at
a time, alternating between the three, until all are tight.
16. Now you need to install the drive belts onto both the motor and the blender pulley. You
may need to move the motor to do this. The plate that holds the motor to the top of the
base has slots with bolts that can be loosened to allow for this movement.
17. Once the drive belts are on the pulleys, move the motor back and away from the blender
until there is a deflection of 5/16” (7.9mm) when applying 5 to 7 pounds of force to the belt.
18. Secure the motor and set the blender back on all four legs.
19. Install the seal. See the instructions for setting the drive collar and seal replacement.
20. Place the casing gasket on the back plate and install the back plate on the shaft.
21. Install the impeller by tightening it down with the impeller nut, making sure the impeller nut
gasket is included.
22. Place the screen to the notch on the inside of the casing. Check to see the screen fits
snugly and does not spin.
23. Firmly place the casing on the back plate and use the casing clamp to secure.
24. Install the seal guard below the casing.
25. Place the inlet adapter above the casing. Secure the adapter to the casing with the clamp
and gasket.
26. Add the diffuser and suction tube assembly to the top of the inlet adapter. Secure with the
clamp and gasket.
27. Install the butterfly valve if supplied with the blender.

Maintenance Ampco Pumps Company
Page 12
The AC+ Dry Blender requires normal cleaning and inspection to insure its best
performance. The blender is relatively maintenance free but Ampco Pumps Company
recommends periodic inspection of seals and seal faces. Worn or damaged parts that
may include cuts or abrasions to seals or nicks or cracks to seal faces, should be replaced
upon detection. In order to clean and sanitize the blender, it is necessary to disassemble all
the parts to the AC+ except for the drive motor.
1. Disconnect the liquid supply piping and the discharge piping from the
blender.
2. Remove the clamp securing the hopper to the AC+ Dry Blender. **The
AC+4329 is normally not ordered with a hopper and valve. If that is the case
with your blender, skip to step 5.
3. Remove the clamp connecting the end connections of the Butterfly valve.
4. Refer to valve manual for disassembling the valve.
5. Remove the clamps and blender tubes, beginning at the top and working
towards the bottom. Continue until you reach the casing.
6. Remove the clamp that secures the casing to the back plate. Use both
hands to firmly grasp the casing, pulling it up and off the back plate. **A
gasket separates the casing and back plate. Do not use a tool to try and pry
them apart. This could damage the surfaces of the adapter ring and the
gasket. Firmly tugging the casing should separate the casing from the back
plate.
7. Remove the screen inside the casing.
8. Remove the impeller and back plate. Protect the sealing surface of the
back plate against all nicks and scratches when removing for cleaning and
disassembly.
9. Rinse all disassembled parts with lukewarm water (approximately 100° F)
until all traces of product are removed.
10. Clean all the components with an all-purpose, powdered alkaline cleaner,
following manufacturer’s recommendations.
11. Immediately rinse with lukewarm water until all of the cleaning agent has
been removed.
12. Rinse with hot water.
13. Place components so they will drain and air dry.
14. Inspect o-rings and replace if necessary.
15. Before reassembling, spray gaskets with a sanitary lubricant.
16. If any damaged or worn parts are noticed during cleaning, replace them
before reassembling the unit.
17. Reverse the order of disassembly to reassemble the blender.
WARNING
Relieve pressure and remove all fluid from blender prior to disassembly
WARNING
Turn off electrical power supply and Lock Out before servicing or maintenance.

Setting the Drive Collar and Seal Replacement
Blenders with D or DG Seals
To replace the seal, assemble the spring, seal cup, o-ring seal, and carbon seal. Install as a
unit, taking care that the slot in the seal cup is aligned with the pin on the drive collar. Gentle
finger pressure will overcome o-ring resistance on the shaft.
When the carbon seal is replaced, the location of the drive collar should be checked and
relocated if necessary. Use one of the two following methods.
Set the Drive Collar by Measurement
1. Install the back plate, gasket, and casing.
2. Install and tighten the casing clamp.
3. Behind the back plate, mark the correct location of the drive
collar by scribing a line on the shaft. See Figures 1-3 where
point A is 11/32” (0.87mm)
4. Remove the casing clamp, casing, and back plate.
5. Place the drive collar on the shaft, setting it in relation to the
scribe mark and tighten set screws.
6. Install the seal spring, cup, seal o-ring, and carbon seal onto the
shaft.
Set the Drive Collar by Position
1. Set the spring, cup, o-ring seal, and carbon seal on the drive
collar. Check that the spring does not rest on the tab that is bent back. A portion of the
spring is offset to provide clearance for this tab. Care must be taken to ensure that the pin
on the drive collar is in line with the slot on the cup.
2. Install the spring, cup, o-ring, and carbon seal as a unit onto the shaft.
3. Install the back plate and casing.
4. Clamp the casing to the back plate and tighten the clamp.
5. To locate the drive collar position, slide the collar and seal assembly towards the back
plate until the o-ring and carbon seal are pushed tight against the back plate.
6. Slide the drive collar back from the back plate by 1/32” (0.79mm). Tighten the set screws
to secure the drive in this location.
7. Install the seal spring, cup, seal o-ring and carbon seal onto the shaft.
8. For DG seals, set the DG insert and gaskets into the gland ring and screw the gland ring to
the back plate.
NOTE: Extra care should be taken when assembling AC+ Blenders with type DG seals. Incorrect stub
shaft settings will allow the impeller hub to contact the inboard face of the stationary seal seat.
Interference of the impeller hub and seal seat face will cause wear of impeller hub and damage to the
inboard or secondary seal face of the clamped-in seat. Visual inspection is recommended after
installation of the impeller and before installation of the casing to ensure clearance between the impeller
hub and seal face. If no clearance is visible, the blender should be disassembled and the stub shaft
moved forward to provide at least 1/32” (.79mm) clearance between the impeller hub and seal seat face.
Reset seal drive collar if necessary.
If the drive collar is properly positioned and seal components are properly installed, the shaft should
rotate freely by hand. If excessive effort is required to rotate the shaft, check to be sure that all
components are properly installed and the drive collar is properly installed.

4. Remove the casing clamp, casing, and back plate.
5. Place the follower, one carbon seal, one seal oring, one cup, and the drive collar on the
shaft.
6. Set the drive collar to the scribe mark shown in Figure 3 and secure it to the shaft by
tightening the set screws.
7. Install the remaining seal components, including the seal spring, cup, seal o-ring, and
carbon onto the shaft. Take care that the slot in the seal cup is aligned with the pin on the
drive collar. Gentle finger pressure will overcome o-ring resistance on the shaft.
8. Place the stuffing box and back plate assembly over the stub shaft and the seal
components.
9. Next set the follower onto the stuffing box and secure it by tightening the four screws.
10. Assemble the seal guard and tighten the nut.
11. Attach the water inlet and outlet to the stuffing box.
