There are several types of pumps used in mechanical engineering.

• Centrifugal pumps

• Reciprocating pumps

• Rotary pumps

• Diaphragm pumps

• Gear pumps

• Vane pumps

• Screw pumps

• Jet pumps

• Peristaltic pumps

• Piston pumps

The parts of a pump include impeller, casing, shaft, bearings, seals, and motor.

• Impeller: Rotating component that imparts energy to the fluid.

• Casing: Encloses the impeller and directs the flow of fluid.

• Shaft: Transmits the rotational motion from the motor to the impeller.

• Bearings: Support the shaft and reduce friction.

• Seals: Prevent leakage of fluid along the shaft.

• Motor: Provides the power to drive the pump.

Condensers are devices used to condense a substance from its gaseous to its liquid state.

• There are two main types of condensers: air-cooled and water-cooled.

• Air-cooled condensers use air as the cooling medium, while water-cooled condensers use water.

• Examples of air-cooled condensers include car radiators and air conditioning units.

• Examples of water-cooled condensers include cooling towers and refrigeration systems.
