will increase, and flow rate will reduce.

Turn the knob counterclockwise, the scale value will reduce, tube
pressure gap will increase, the output pressure of the pump head tube
will reduce, and flow rate will increase.
Note:

The larger the scale value, the greater the output pressure of the pump
head tube, the faster the tube wears, and the lower the tube life.
Therefore, it is not recommended to use it at the position of the scale 5
for a long time.

The smaller the scale value, the smaller the output pressure of the pump
head tube, and the lighter the tube is compressed. The pump head is
more prone to "no liquid" or "output liquid dropping" during use.
Therefore, please use the scale 1 with caution.
6. Troubleshooting
If the pump head flow rate is very low or no flow rate, please check the
following:

Check whether there is liquid from input side.

Check whether the suction side tube is blocked by suction wall.

Check whether the tube is cracked.

Check for blockages or kinks in the tube.

Check whether the wall thickness of the tube is correct.

Check whether all valves in the tube are open.

Check whether the direction of the pump rotation is correct.
