  • DIAPHRAGM PUMPS | How Does a Diaphragm Pump

    2021-4-27 · A metering pump, and any chemical injection pump, is a positive displacement type pump. What is a positive displacement pump? A positive displacement (PD) pump moves a fluid by repeatedly enclosing a fixed volume and moving it mechanically through the system. The pumping action is cyclic and can be driven by pistons, screws, gears, rollers, diaphragms or vanes.
