In general, two flexible diaphragms that move back and forth form a temporary cavity. The two diaphragms serve as a partition barrier separating the liquid and the air.
The term "diaphragm pump" refers to a type of positive displacement pump that uses a diaphragm made of thermoplastic, rubber, or Teflon in a reciprocating motion. These devices' flow rates don't vary significantly with discharge pressure. It means the pump doesn't operate at the designated pump speed.

Allowing fuel into a chamber and pushing it out with pressure
