Plunger pumps and diaphragm pumps

Thread Content

Are the working principles of piston pumps and diaphragm pumps very similar?
Reply #22022-03-18
They all belong to positive displacement pumps. One is the plunger performing reciprocating work, and the other is the diaphragm undergoing reciprocating deformation to do work; for reference.

1. The plunger moves back and forth like a tie rod, similar to the piston in an automobile engine； 2. The diaphragm operates on a principle similar to that of the human heart, functioning by expanding and contracting two membranes to inhale and exhale.
