5 Installation
5.1 Before installation
5.1.1 General instructions to prepare the product
1. Read the material safety data sheet of the pumped liquid.
2. Check if the product is delivered according to the specifications.
3. Install the product on a clean, stable and level surface. You can also use
vibration absorbers to decrease vibration effects.
4. Make sure that you can reach the product after installation for operation and
maintenance purposes.
5. Make sure there is sufficient ventilation to cool the motor.
6. Install power meters, pressure switches or a level switch to prevent the product
from running dry or from running with a closed discharge line.
WARNING
The product is heavy. Use the correct lifting gear to lift the product.
CAUTION
Handle the product with care during transport to prevent damage to the
pump shaft.
WARNING
Wear the correct personal protective equipment.
Note
The long coupled model TKm is supplied on a common base plate and
needs to be secured with screws on a concrete or metallic base of ade-
quate dimensions and level.
CAUTION
This product has been aligned with laser equipment for the best repre-
sentation of the test results. Transport and installation can cause devia-
tions. After installation and before commisioning, make sure that the
alignment is correct.

Installation
User Manual Chemical centrifugal pumps with mechanical seal V080716 17
7. Dry the product.
5.1.2 Filling the bearing assembly with oil (no. 42b only)
The product you have received is completely assembled, but holds no oil (the frame
is empty). After testing the product, it is emptied for shipment.
1. Choose the lubricating oil for its viscosity to ensure a proper lubrication at a
normal operating temperature.
/i
2. Fill the bearing housing with oil through the oil filler until the oil appears at the
bottom of the oiler. The oil filler is located at the top of the bearing housing.
3. Hinge and fill the transparent pot and return it to its normal position. If
necessary, do this step again in order to have a stabilized level in the
transparent pot.
CAUTION
If you let the product run dry or if you run the product with a closed
discharge line for more than 2 minutes, this can damage the product.
Note
Due to factory testing, the product might contain some water. For liquids
that may not come in contact with water, the product must be dried
before taking it into use.
WARNING
Before starting the installation, fill the bearing housing with suitable oil.
Standard Consult the most recent
ISO standard for the
acceptable values.
Viscosity at 40 °C 32 mm2/s
Burning point 222 °C
Maximum temperature 100 °C

5.2 Installation of the piping
5.2.1 General instructions to prepare the piping
1. Make sure that:
- the diameter of the piping is calculated for maximum flow velocities as
specified in § 5.2.2.
- the pipe connections are free of tension. Take into account the expansions
of pipes if you pump a liquid with a high temperature. It is recommended to
use expanders and correct supports for the pipes to remove tension and to
inhibit the transfer of vibrations to the product.
- you avoid looping. If looping is unavoidable, use a downward loop instead
of an upward loop.
- you can remove trapped air from the piping and from the product.
2. Make sure that:
- you use long reducers to match the piping and pump connections gradually.
- you do not use too many elbows and connection pieces.
- you place a valve near the pump, the suction line and the discharge line, for
maintenance purposes.
5.2.2 Installation of the suction line
1. Make sure that:
- the suction pipe is as short as possible.
- an elbow or valve is far enough from the pump housing (at least 5x suction
line bore).
- only full bore valves are used.
- upward bends are avoided.
- all welding areas and connections are fully closed.
Note
Pressure loss caused by long pipings needs compensation by using
a larger pipe diameter.
WARNING
Make sure that the flow velocity is less than 1 m/s.

Installation
User Manual Chemical centrifugal pumps with mechanical seal V080716 19
2. Make sure that:
- you use a foot valve when the liquid level is below the suction level.
- you use a strainer when the pumping liquid contains particles of 2 mm1) or
3mm
2).
Suction lift
1. Make sure that:
- the suction lift (X) with a standard
seal is less than 2 m.
- the NPSHavailable is 120% of the
NPSHrequired.
2. Use a foot valve (A).
Flooded suction
1. Make sure that the liquid level (X) is
above the centre line of the pump.
1. For the KR-15-85 – KR-32-95 models.
2. For the KR-TK-HD-40-125 – KR-TK-HD-150-250 models.
Note
For a higher suction lift,
contact your supplier.

Installation
User Manual Chemical centrifugal pumps with mechanical seal V080716 20
Self priming
1. Refer to the supplementary
instructions.
5.2.3 Installation of the discharge line
1. Use a non-return valve (A) when:
- the discharge line is below the
liquid level.
- the suction line is very long.
- the static discharge head exceeds
15 m.
- a backflow of liquid is not allowed.
- two or more products are
connected parallel to a common
piping.
2. Use a filling connection (B).
3. Install air vents and expansion joints in
areas where air can accumulate, when
you use very long horizontal parts.
4. If possible, install a pressure gauge near the product.
5. Install a drain valve to empty the discharge line when you need to clean it or in
case of a freezing hazard.
5.2.4 Seal flushing device
For lubrication and cooling of the secondary seal, the seal box is provided with 2
connectors for a ½" hose.
X
WARNING
Make sure the flow velocity is less than 3 m/s.
