Dynamic pump
Positive displacement pumps, unlike centrifugal or roto- dynamic pumps , theoretically can produce the same flow at a given speed (RPM) no matter what the discharge pressure. Thus, positive displacement pumps are constant flow machines. However, a slight increase in internal leakage as the pressure increases prevents . The centrifugal or roto- dynamic pump produce a head and a flow by increasing the velocity of the liquid through the machine with the help of the rotating vane impeller. Centrifugal pumps include radial, axial and mixed flow units.

This class is essentially just theory. Learn about the pump types, when and why they are used. Sealless pump is a term used to define a pump that does not utilize a dynamic shaft seal as the method to limit leakage to atmosphere. This is accomplished by the use of a canned motor or a magnetic coupling.

Less familiar types with more limited usage include ejectors, pulsators, gas lift pumps, hydraulic elevators and various miscellaneous types difficult to classify.
Across the industry, professionals are constantly working to develop and implement the latest in pump and valve technology. Recently, EmpoweringPumps. But for those who need a brush up on pump basics, we thought it would be . Kinetic ( dynamic ): In these pumps , energy is continuously added to increase the fluid velocities within the machine to values greater than those occurring at the discharge, so subsequent velocity reduction within or beyond the pump produces a pressure increase.

Pump rate depends only on the volume or depth of water in the wet well upstream. These types of pumps are suitable if the gravity pipe downstream has sufficient capacity to receive the pump discharge. If the forcemain is modele the dynamic head pump (Type 3) will be a more suitable choice because the pressure head . Fixed Displacement, Pressure Balance Hydraulic Gear Pumps.
