Types of Centrifugal Pump
The shaft coupling is the connecting element between the electric motor and the pump hydraulic system. Slip-free shaft couplings employed in centrifugal pumps are divided into rigid and flexible shaft couplings.
However, positive displacement pumps come in a wider variety such as gear, lobe, peristaltic, screw, and many other types of pumps. The most common type among centrifugal pump is the radial flow pump. These centrifugal pumps use a rotating impeller to create a vacuum in order to move fluid.
“A centrifugal pump uses rotation to impart velocity to a liquid.” Every centrifugal pump includes an impeller. The impeller is the hydraulic component that rotates to impart velocity to the pumped liquid. “A centrifugal pump converts velocity into flow.” Every centrifugal pump includes a casing.
Centrifugal pumps are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor.

Thus the mechanical seals are the devices that form the packing between the rotor and the stationary part of the centrifugal pumps to prevent the leakage of the fluid being pumped by the pump. There are two main parts of the mechanical seals: one is the stationary part, which is connected to the pump housing and the other is the rotating part which is connected to the rotating shaft.
A centrifugal pump is a machine that uses rotation to impart velocity to a liquid, it then converts that velocity into flow. Centrifugal pumps are made up of two primary components: an impeller and a casing. The rotating impeller generates velocity and the casing converts velocity into flow.

The centrifugal pump and positive displacement pump are the two primary categories of pumps. Centrifugal pumps are the most widely used, but there are a greater variety of positive displacement pumps, including gear pumps, peristaltic pumps, reciprocating pumps, screw pumps, and lobe pumps.
For Centrifugal Pump, priming is required only when the elevation of liquid in the suction tank/pond is less than the elevation of the pump. Centrifugal pump cannot "suck" / "pull" the liquid but it pushes the liquid. Liquid enters in the suction of centrifugal pump by the energy it posses (atmospheric pressure in the suction tank).
The progressive cavity pump is a positive displacement pump. This is different than the more commonly used centrifugal pump. A centrifugal pump is a good, economical choice when pumping water like fluids with low viscosity and when a fixed flow and constant discharge pressure are the basis of the application.
Some centrifugal pumps contain diffusers. A diffuser is a set of stationary vanes that surround the impeller. The diffuser directs the flow, allows a more gradual expansion and therefore increases the efficiency of the centrifugal pump. Shaft (Rotor). The impeller is mounted on a shaft.
Figure 1: Sketch of a reciprocating pump [2]. Centrifugal pumps [1]: Centrifugal pumps are pumps containing a rotating impeller mounted on a shaft turned by the power source. The rotating impeller increases the velocity of the water and discharges it into a surrounding casing shaped to slow down the flow of water and convert the velocity to pressure.
Internal rotary gear pump working principle An internal rotary gear pump employs a positive displacement principle. The pump features a casing in which a dual gear (an outer rotor gear and an internal idler gear) and crescent assembly is housed.
Flow from rotary PD pumps is relatively unaffected by differential pressure and is smooth and continuous. Rotary PD pumps have very tight internal clearances which minimize the amount of liquid that slips back from discharge to suction side of the pump. Because of this, they are very efficient. These pumps work well with a wide range of viscosities, particularly high viscosities.

The mechanical seals help sealing the rotating part of the shaft against the stationary part of the pump housing. Thus the mechanical seals are the devices that form the packing between the rotor and the stationary part of the centrifugal pumps to prevent the leakage of the fluid being pumped by the pump.

Pumps can be classified by their method of displacement into positive displacement pumps, impulse pumps, velocity pumps, gravity pumps, steam pumps and valveless pumps. There are two basic types of pumps: positive displacement and centrifugal.
Centrifugal pumps uses impellers to produce vacuum/vaccum or involute pressure in the involute casing for suction and discharge of fluids. Vane pumps uses vanes (stators) and rotor setup instead of impellers to create pressure.
