Before servicing pump, disconnect
electrical power source, carefully relieve
all pressure and drain all fluids from
pump and connected piping.
DESCRIPTION
Before servicing pump, disconnect electrical power source.
The QIM/QDB Mixer Series closed-coupled pumps are made up of two sections, power or drive
section and the liquid end or pump section.
The pump is mounted to the frame of the drive motor by means of an adapter, and is coupled
to the motor shaft. The impeller mounts on the stub shaft and is retained by one of the three
methods. The casing is clamped to the adapter, greatly simplifying removal, and also permitting
positioning of the discharge outlet through 360º. The external, balanced seal assures long seal
life. The drive motor is mounted on a frame having adjustable legs providing simple installation
and leveling.
INSTALLATION GUIDELINES
UNPACKING EQUIPMENT
Check the contents and all wrapping when unpacking your equipment. Inspect all parts for
damage that may have occurred during shipping. Report any damage to the carrier.
LOCATION AND INSTALLATION
The pump unit should be located as near as possible to the liquid source and in a position where
the suction piping can be short and direct with a minimum number of elbows and ttings. It
should also be readily accessible for inspection and cleaning.
The pump unit as received from the factory is ready for installation. To install it, attach a hoist if
necessary, loosen the set screws in the adjusting leg brackets, and individually adjust the legs
until the pump is leveled. Tighten the set screws.
Attach the suction and discharge piping. Be sure suction and
discharge piping is properly supported to avoid any strain on the
pump casing.

HOW TO INSTALL THE PIPING
GENERAL
This section provides some do’s and do not’s of piping which will aid in obtaining the maximum
eciency and service from your pump. Piping should be independently supported at both the
suction inlet and discharge outlet. Care should be taken that piping is properly aligned and does
not put any strain on the pump casing. The piping should have as few bends as possible.
SUCTION PIPING
The suction piping should be short and follow a direct route with a minimum number of elbows
and ttings. Elbows should be located as far as possible from the suction inlet to prevent head
loss due to increased friction. Excessive friction losses in the suction line could result in pump
cavitation, causing poor performance, noise, vibration, damage to equipment and possible
damage to uid.
Whenever possible the diameter of the piping at the suction inlet should be increased in size, an
eccentric tapered reducer should be used instead of a concentric tapered reducer to prevent
air pockets from forming and impairing pump eciency. In turn, the eccentric reducer may be
placed at the inlet of the pump and should be positioned so the straight side is up. A horizontal
suction pipe must have a gradual rise to the pump. A high point in the suction line will form an
air pocket and prevent proper pump operation. All joints in the suction line should be air tight, to
prevent air leakage which can reduce pump capacity and eciency.
DISCHARGE PIPING
Position of the pump discharge is preferably either vertical or top horizontal. The discharge piping
should be short and direct with a minimum number of elbows and ttings. Elbows should not be
used at the discharge outlet, as the friction encountered would be increased, resulting in head
loss. However, use of a large discharge pipe than recommended may reduce the total pump
head, but increase the pump volume, which can cause pump vibration due to overload. Use
of a discharge pipe smaller than the pump discharge outlet increases the total pump head but
decreases the volume. If a reducer is required on the outlet port of the pump and the discharge
is vertical a concentric reducer should be used. If the
discharge is horizontal an ec centric reducer should be
used and should be positioned so the straight side is
down.
LOCATING VALVES
In suction lift applications where the lift is not very
high, it may be desirable to install a foot valve, to
facilitate priming, and to prevent draining o of the
liquid back to the source. A throttling valve should
be installed in the discharge piping to provide control
pump ow rate and prevent motor overload.

START THE ASSEMBLY
It is highly recommended that you use the general diagram to identify
the components and thus be able to carry out the assemblies and sub-
assemblies that will be explained below.
1. LEG BRACKET ASSEMBLIES
The leg bracket assemblies are optional. They allow to level the pumps adjusting the legs
vertically. The size of the brackets (209) and legs (207) depend on the NEMA or IEC motor
frame.
First make the sub-assemblies of the legs to the brackets with the hexagonal screws (209A).
Next, with the hexagonal screws (209B) x the brackets to the motor base; You may need
to lift the motor to make this assembly. Figure A.

3. SPACING OF THE IMPELLER AND STUB SHAFT
The correct functioning of the pump depends on the separation of the impeller (2S) from
the backplate (11A) and the xation of the stub shaft (6P) on the motor shaft. Follow the
next steps to x the stub shaft on the motor shaft:
3a. Position the stub shaft collar (92) with the corresponding Allen screws (92A) loosely
on the stub shaft and place it on the motor shaft, it must slide in and out without problem.
Figure D.
3b. Place and x the backplate into the adapter. Two long pins are used in the adapter
(71A) normally preassembled; if there are no pins please insert them into the holes drilled
in the adapter ring. Those pins help to x the backplate into the adapter using two bended
backplate pins (11F). The bended pins shall be clockwise seeing them from the back side
of the backplate.
Seat the backplate on the adapter and turn it counterclockwise until the bended pins
engage with the long pins. If the bended pins get separated or they do not mate with the
long pins, try to adjust them by turning in or out. Figure E.
The bended pins help to keep the backplate in position to make the assembly easier.

3c. Put the impeller key (24C) on the keyway of the stub shaft. Place only the rotary holder
of the mechanical seal (96A) together with its respective O-ring (96E) until it seats on the
shoulder of the stub shaft. The impeller key does not interfere with the mechanical seal
drive collar.
Take the impeller nut (24D) and place the impeller gasket (91B) on it, then place the impeller
in the stub shaft and tighten with the impeller nut compressing the assembly. Figure F.
Use a 5/8” hexagonal socket for models 114 and 214 and a 7/8” hexagonal socket for the
rest of models to tighten the nut.
To prevent the stub shaft-impeller assembly from turning you can use a Ø3/8” rod in the
bore that has the stub shaft on its side and thus be able to tighten or loosen the impeller
nut. Figure G.
Remember that you can use water or dishes soap to lubricate or glue O-rings and
gaskets to the metal elements to facilitate assembly.

3d. Once the assembly is tightened place a spacer of 0.060” (1.53 mm) thru 0.070” (1.78
mm) between the back of the impeller and the front of the backplate. You may use a
caliper, some shims or a washer with that width to set the critical distance for the correct
performance of the mechanical seal. Keep aligned both, the stub shaft slot and the collar
slot before tightening the screws on the shaft collar. Compress the impeller against the
backplate with the spacer between them and proceed to tight the screw or screws on the
shaft collar. Now turn the impeller by hand, it must turn with no restriction. Check that
every blade is separated the distance indicated. Figure H.
Use the torque values for tightening the collar screws indicated in the Chart 2.

3e. Using the 3/8” rod and the hexagonal socket and wrench to untighten the impeller
nut to remove the elements previously assembled. Take the impeller nut, impeller gasket,
impeller and impeller key o. Do not forget to remove also the spacer used to determinate
the stub shaft position. Continue assembling the mechanical seal (96). Figure I.
4. ASSEMBLING THE SINGLE MECHANICAL SEAL
4a. Place into the backplate the stationary face of the mechanical seal (96C) with its O-ring
(96F). First place the O-ring on the stationary face, remember that you can use water or
dishes soap to lubricate or glue O-rings and gaskets to the metal elements to facilitate
assembly, place both pieces in the inner housing of the backplate taking care that the
notch in the stationary face coincides with the backplate pin (96H). Push until the seal
surface fully seats on the surface of the housing. Figure J.

Place and x the backplate with the stationary seal into the adapter, as in step 3b.
4b. Assembly the rotary single seal face (96B), the rotary seal O-ring (96G), spring (96D)
and rotary holder O-ring (96E) into the rotary holder (96A). Remember that you can use
water or dishes soap to lubricate or glue O-rings and gaskets to the metal elements to
facilitate assembly.
First place the O-ring in the groove on the rotary holder. Then place the spring inside the
rotary holder taking care the tip on the spring ts the machined slot in the rotary holder.
Put the rotary seal face into the rotary holder. The tip on the spring must t the machined
slot in the rotary seal face. Then compress until the rotary seal face is inserted. Finally
place the rotary holder O-ring in the groove on the front of the holder. Figure K.
4c. Insert the whole rotary seal assembly into the stub shaft, the seal will contact the
stationary seal face placed previously in the backplate. Push to compress the assembly
and then insert the impeller key. Put the impeller and tight it with the impeller nut. Do not
forget to place the impeller gasket into the impeller nut. Figure L.

Tight the assembly as previously did before in step 3c. For models 114 and 214 use a
torque of 25 ft.lb and a torque of 40 ft.lb for the rest of the models when tightening the
impeller nut. Figure M.
5. ASSEMBLING THE CASING
5a. Once the mechanical seal has been installed and the impeller-impeller nut assembly
has been tightened the casing must be mounted.
Place the casing O-ring (90A) onto the groove on the front of the backplate. Then take the
casing (1) and locate it onto the adapter, positioning the discharge at the desired location.
Place the clamp assembly (75) around the casing. Figure N.
In a lower horizontal position, the casing can be self-drainable.

5b. Tighten the clamp assembly to close the casing to the adapter, be sure it is centered
and level around all the circumference. Avoid that the casing ts unevenly in the adapter to
prevent it from rubbing against the impeller. A rubber mallet may be helpful when installing
the casing hitting softly to even the separation while tightening the clamp assembly. Figure
O.
5c. Check turning by hand the impeller it does not rubs against the casing. The assembly
may turn easily without restriction. If there is any sound or sensation of rubbing, you need
to check the whole assembly, disassembly and repeat it again.
5d. If everything is ne, to complete the assembly place the protective guard (131) that is
xed with a hexagonal screw (131A) into the adapter.
It is highly recommended for safety reasons not to operate the equipment if it is not placed
in the adapter.
Notes.
Before starting the pump check that the motor turns in a counterclockwise direction.
Keep the suction line ooded and the mechanical seal lubricated with the uid which
is going to be pumped. Never operate the pump when dry or it may damage the seal.
Maintain enough NPSH available in the suction line to avoid the pump to cavitate.
Do not support the weight of the pipe on the pump casing, the pipe must be adequately
supported to avoid this.
The impeller for QIM/QDB series must be trimmed to a specic diameter. If you
need to spare the impeller do not forget to tell it is for a QIM/QDB equipment.
