Rotodynamic pumps are based on bladed impellers which rotate within the fluid to impart a tangential acceleration to the fluid and a consequent increase in the energy of the fluid.
One of the types of positive displacement pumps is a rotodynamic pump which converts mechanical energy into hydraulic energy by centripetal force on the liquid.
The total flow rate of piston pump is the quantity delivered by the pump for each piston stroke.
Typically, a rotating impeller decreases the velocity of the fluid.
Pumps are used for pumping liquids that vary widely in viscosity.

Cavitation is the term used to describe the formation of bubbles in liquid flow when the local pressure falls to around vapor pressure. Two effects are experienced in the pump: a reduction in flow rate (accompanied, particularly in centrifugal pumps, by additional noise) and in surface damage and material removal. In general, cavitation occurs in the suction region of a pump or the inlet port and valve area of a positive displacement pump.

Вихревой насос
В вихревых насосах для передачи энергии от рабочего колеса к жидкости и создания напора используется энергия вихревого движения жидкости. В корпусе насоса вращается рабочее колесо с лопастями. В самом корпусе насоса имеется кольцевой канал, который заканчивается нагнетательным патрубком. Жидкость поступает через входное отверстие к основаниям лопастей, отбрасывается центробежной силой в кольцевой канал, в котором приобретает вихревое движение, и перемещается к выходному патрубку. На этом пути жидкость неоднократно попадает в пространство между лопастями, где ей дополнительно сообщается механическая энергия.
Струйный насос
Перекачка жидкости в струйных насосах осуществляется с помощью кинетической энергии другой жидкости, которую называют рабочей. В качестве рабочей жидкости очень часто применяют пар или воду. Рабочая жидкость поступает с большой скоростью из сопла через камеру смешения в диффузор, увлекая перекачиваемую жидкость. Такие насосы часто используются для подачи воды в паровые котлы.
Шестеренчатый насос
В корпусе шестеренчатого насоса заключены две шестерни. Когда зубья шестерен выходят из зацепления, образуется разряжение и происходит всасывание жидкости. Она поступает в корпус, захватывается зубьями шестерен и перемещается вдоль стенок корпуса в направлении вращения. Когда зубья вновь входят в зацепление, жидкость вытесняется и поступает в напорный трубопровод.
