Kirloskar Brothers Field Service Engineer Interview Questions, Process, and Tips

Pumps are mechanical devices used to move fluids from one place to another.

• Pumps can be used in various industries such as water treatment, oil and gas, and manufacturing.

• There are different types of pumps including centrifugal pumps, positive displacement pumps, and diaphragm pumps.

• Pumps can be powered by electricity, engines, or manual operation.

• Common applications of pumps include pumping water from wells, circulati...read more

Types of pumps include centrifugal pumps, positive displacement pumps, and axial flow pumps.

• Centrifugal pumps: use a rotating impeller to increase the pressure of a fluid.

• Positive displacement pumps: move fluid by trapping a fixed amount and forcing it through the discharge.

• Axial flow pumps: move fluid parallel to the pump shaft.

• Examples: Centrifugal pump - water pump, Positive displacement pump - diaphragm pump, Axial

Centrifugal pumps work by converting rotational kinetic energy into hydrodynamic energy to move fluid through the pump.

• Centrifugal pumps use an impeller to rotate and create a centrifugal force that pushes the fluid outward.

• The fluid enters the pump through the center of the impeller and is accelerated radially outward.

• The kinetic energy of the fluid is converted into pressure energy as it exits the pump through the di...read more

Seals in pumps prevent leakage and maintain pressure, ensuring efficient operation.

• Seals prevent leakage of fluid from the pump

• They help maintain pressure within the pump system

• Common types of seals include mechanical seals, packing seals, and lip seals

• Mechanical seals use two flat surfaces pressed together to prevent leakage

• Packing seals use a material like graphite or PTFE to create a seal

• Lip seals use a flexible lip

A mechanical seal is a device that helps prevent leakage between two moving or stationary parts in a machine.

• Used in pumps, compressors, and other rotating equipment

• Consists of two main parts: stationary seal face and rotating seal face

• Seal faces are pressed together to create a barrier against leakage

• Common materials include carbon, ceramic, and tungsten carbide

• Regular maintenance and monitoring are necessary to ensur
