Darling Pumps Assistant Manager Interview Questions and Answers for Experienced

There are two main types of pumps: centrifugal pumps and positive displacement pumps.

• Centrifugal pumps use a rotating impeller to create a flow of fluid, while positive displacement pumps move fluid by trapping a fixed amount and forcing it through the system.

• Examples of centrifugal pumps include water pumps and sewage pumps, while examples of positive displacement pumps include gear pumps and diaphragm pumps.

Centrifugal force in centrifugal pumps is the force that pushes the fluid outward from the center of rotation.

• Centrifugal force is the force that pushes the fluid outward from the center of rotation in a centrifugal pump

• It is created when the impeller of the pump rotates, causing the fluid to move radially outward

• This force is responsible for creating the pressure difference that allows the pump to move fluid from the ...read more

Induction motors work on the principle of electromagnetic induction to create a rotating magnetic field.

• Induction motors have a stator with coils that are connected to an AC power source.

• When the AC power is applied, it creates a rotating magnetic field in the stator.

• This rotating magnetic field induces currents in the rotor, which in turn creates a magnetic field.

• The interaction between the stator and rotor magnetic f...read more
