2. Micropump - Wikipedia

   en.wikipedia.org/wiki/Micropump

   The compression ratio of the micropump as one of the critical performance indicator is defined as the ratio between the stroke volume, i.e. fluid volume displaced by the pump membrane over the course of the pump cycle, and the dead volume, i.e. the minimum fluid volume remaining in the pump chamber in pumping mode.

3. Peristaltic pump - Wikipedia

   en.wikipedia.org/wiki/Peristaltic_pump

   A peristaltic pump, also commonly known as a roller pump, is a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained in a flexible tube fitted inside a circular pump casing. Most peristaltic pumps work through rotary motion, though linear peristaltic pumps have also been made.

4. Screw pump - Wikipedia

   en.wikipedia.org/wiki/Screw_pump

   One of the most common configurations of a screw pump is the three-spindle screw pump. Three screws press against each other to form pockets of the pumped liquid in the grooves of the screws. As the screws rotate in opposite directions, the pumped liquid moves along the screws' spindles.

5. Pump - Wikipedia

   en.wikipedia.org/wiki/Pump

   Liquid ring pumps have a dedicated intake for the priming liquid separate from the intake of the fluid being pumped, as the fluid being pumped may be a gas or mix of gas, liquid, and solids. For these pumps the priming liquid intake must be supplied continuously (either by gravity or pressure), however the intake for the fluid being pumped is ...

6. Slurry pump - Wikipedia

   en.wikipedia.org/wiki/Slurry_pump

   A slurry pump is a type of pump designed for pumping liquid containing solid particles. Slurry pumps changes in design and construction to adjust to multiple type of slurry which varies in concentration of solids, size of solid particles, shape of solid particles, and composition of solution. Slurry pump are more robust than liquid pumps; they ...

   9. air liquid mixture 10. pump outlet L: liquid, usually wastewater LL: liquid level V: Vessel G: Gravel or solids. An airlift pump is a pump that has low suction and moderate discharge of liquid and entrained solids. The pump injects compressed air at the bottom of the discharge pipe which is immersed in the liquid.
