Guys, does a diaphragm pump need to be vented? Why is venting necessary? Is it okay not to vent it?

Gas compression and expansion occupy the volume space of the diaphragm； 2. The presence of gas affects the sealing of the check valve

We have been using it; gas needs to be released from within the diaphragm during startup

There’s no need for exhaust; volume pumps don’t require exhaust, right?
