User manual Pomac SP-LR pumps
CE/ SP-LR (1306) EN-01 17
4. Installation
4.1. General
⚫The foundation must be smooth and level.
⚫For the KAM design set the adjustable legs using the leg adjustment feet (38), in such a
way that the pump is stable on all 4 legs! Secure the leg adjustment feet with the lock
nuts (39).
⚫Verify that the system pressure does not exceed the permitted operating pressure.
⚫Verify that the pipes do not show any leakage.
⚫The pipes must be installed and connected stress-free.
⚫Mount a filter between the pump and the suction line. The gap between the impeller and the
pump casing is only 0.3 mm and particles can cause the pump to drag or seize.
⚫If backflow of the liquid flow is undesired, or there is a chance of undesired liquid mixing,
apply a non-return valve in the suction line.
4.2. Connecting the electric motor
An electric motor may only be connected by a qualified electrician!

User manual Pomac SP-LR pumps
18 CE/ SP-LR (1306) EN-01
5. Putting into operation
5.1. Precautions
5.1.1. General
⚫Check that the shaft can turn freely. To do this, rotate the pump shaft a few times manually.
⚫Check that the fuses have been fitted.
⚫Types IG and IGH are designed as standard with grease lubricated ball bearings that are
provided with grease for their entire life (2RS1).
⚫If type IG(H) is designed with oil lubricated bearings, the bearing housing should be filled
with oil first.
5.1.2. Quench
If provided with quench (shaft seals Q1 and Q12):
1. Connect the quench lines to the quench space. Capacity approx. 3 l/min. The SUPPLY line
must be connected to the LOWER port!
2. Open the inlet and outlet of these lines.
3. Set the required pressure. The maximum pressure is 0.2 bar.
See part 8.4 and 8.5 for an overview of the Quench solution
5.2. Checking the rotation direction
1. Fill the pump with the medium to be pumped.
There must be medium in the pump before putting it into operation. Without medium the
pump cannot create a vacuum. If the pump does not have a positive suction flow, make
sure to fill the pump housing before connecting the piping.
2. Check that the quench or flush system is set to the correct pressure.
3. Switch the pump on briefly.
Take care with any unprotected rotating parts!
4. Check that the rotation direction of the motor corresponds with the rotation direction of the
pump (which is indicated by an arrow on the lantern piece). If the rotation direction is not
correct, swap the connection wires L1 and L2.
This must be done by a qualified electrician!
5. Fit the guard.
5.3. Putting into operation
1. Check that the quench system is set to the correct pressure.
2. Fully open the shut-off-valve in the suction and discharge pipe.
3. Switch the pump on and allow it to come up to pressure.
4. Set the pump to its required operating point.
Remark: Never run the pump against a closed valve.

User manual Pomac SP-LR pumps
CE/ SP-LR (1306) EN-01 19
5.4. In operation
5.4.1. Noise
The noise data stated in this manual refer to normal usage, with an electric motor. Under these
conditions the noise level, measured at a distance of 1 meter and at a height of 1,6 meter, is
below 85 dB(A). If after the passage of time the pump produces excessive noise, this can be an
indication that there is a fault in the pump or elsewhere in the system (e.g. worn out bearings,
cavitation).
5.4.2. Daily maintenance
! Regularly check the pressure of quench supply (if the pump seal is equipped as such)
⚫The valve in the suction pipe must always be completely open
⚫Regularly check that the inlet pressure is not too low to avoid the occurrence of cavitation in
the pump
⚫Regularly check the delivery pressure
⚫Regularly check the shaft seals for leakage.
! The pump may never run without liquid
5.4.3. Cleaning procedure and agents
The pumps are suitable for being CIP cleaned.
Use the cleaning agents recommended for the products.
5.4.4. Periodic maintenance
The pumps basically are maintenance free. Only the following items require periodic attention:
! Periodically check that the quench system is still set at the correct pressure and
capacity!
⚫The electric motor bearings are greased for their entire life and do not require any
maintenance or subsequent lubrication. This also applies to the designs IG and IGH, if
designed with grease lubricated bearings.
⚫Regularly check the oil level for designs IG and IGH, designed with oil bath lubricated
bearings. This oil must also be changed annually or after every 5000 operating hours.
Check that the spent oil is disposed of in the correct manner (environment)!
⚫A mechanical seal may not show any visible leakage. If this is the case, replace the shaft
seal.
⚫If a mechanical seal does not show any visible leakage disassembly is not recommended!

20 CE/ SP-LR (1306) EN-01
5.5. Malfunction
If there is a malfunction in the pump, try to find the cause using the troubleshooting list at the
back of this manual or consult your installer!
Always switch off the current first if you intend to investigate the malfunction yourself.
Remove the fuse or lock the operating switch with a pad lock!
The pump can still be hot or under pressure. Allow the pump to cool down first and if
possible release the pressure from the pump. Always wear the correct personal
protection devices (goggles, gloves, etc.)!
