6 .3 - ROLLER ADJUSTMENT
CAUTION! The roller adjustment is an operation which consists in adjusting the roller brackets to
prevent any internal leakage. An internal leakage considerably reduces the lifetime of the
hose as well as the flow. As a result, it is essential to adjust the rollers according to the
rotation speed of the pump, the desired discharge pressure and the liquid viscosity. Please
contact an Albin representative for additional information on this process.
WARNING! Never run the pump without the front cover.
6 .3 .1 - ROLLER ADJUSTMENT ALP09N TO ALP25N
NOTE : The pressure setting must be checked when a new hose is installed.
1 - Remove the front cover from the pump casing.
2 - Loosen the screws of the bracket that is compressing the hose.
3 - Tighten the bracket screws.
4 - Place the front cover on the pump.
5 - Run the pump and place the palm of your hand over the inlet port (suction side) and check if the fixed roller is adjusted
enough to create a suction. If not, remove the cover again and move the fixed roller until it meets the graduation mark 2. A
vacuum gauge can be used to verify the vacuum performance.
6 - Repeat steps 4 and 5 moving the bracket sideways to marks 2, 3 or 4 until you obtain the correct suction -0.6 bar (-8.7 psi).
7 - Adjust the free roller to the same distance, replace the front cover and test-run the pump. Re-adjust if necessary.
WARNING! The two rollers must be equally adjusted.
