For easy deaeration of the pump:
Install a ball valve (11) with bypass line (back to the dosing tank)
immediately behind the pressure valve
In case of long pressure lines:
Install a check-back valve (12) into the dosing line.
Keep the suction line as short as possible, avoid a tangled suction
line
•
If necessary, use swept bends instead of elbows.
Always lay the suction line rising to the suction valve of the dosing
pump.
•
Avoid loops which cause air bubbles.
For non-degassing media with viscosity similar to water, the pump
can be mounted onto the tank (observe the admissible suction
height).
Preferably flooded suction.
Install a suction line with filter (13) in a way ensuring that the suction
valve remains several centimetres a bove the botton of the tank.
