Shortly explain about positive displacement pump?

Question

Accepted Answer

Positive displacement pump is a type of pump that moves fluid by trapping a fixed amount of it and then forcing it into the discharge pipe.

Positive displacement pumps operate by trapping a specific volume of fluid and then forcing it into the discharge pipe.
These pumps are capable of generating high pressures and are used in various industries such as oil and gas, chemical, and food processing.
Examples of positive displacement pumps include reciprocating pumps, rotary pumps, and diaphragm pumps.
Reciprocating pumps use a piston or plunger to create pressure and move the fluid.
Rotary pumps use rotating mechanisms such as gears or lobes to transfer the fluid.
Diaphragm pumps use a flexible diaphragm to displace the fluid.
Positive displacement pumps are known for their ability to handle viscous fluids and maintain a constant flow rate regardless of the system pressure.

Accepted Answer

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.

Accepted Answer

Positive displacement pumps create high pressure and flow is low . Then the safety is important to volume is low period.
