15 - The horizontal sections of the suction pipe must be a bit inclinated towards to the top in order to avoid the creation
of air pockets, which can damage the pump priming.
16 - In vacuum sucking reduce at min. the friction losses
due to suction pipe. Arrange a check valve on outlet side
in order to:
– avoid the air or liquid reflux during the pause so that to
keep the piping completely full;
– to make easier the starting on load.
