4 Drive Mechanism
This could be an electric motor, engine, or other power source that provides the energy to move the piston or
diaphragm back and forth.
5 Seals and Gaskets
These components prevent leakage of fluid and maintain pressure within the pump.
6 Support Structure
The pump is usually mounted on a sturdy frame or base to provide stability and support during operation.

Reciprocating pumps are commonly used in various applications, including hydraulic systems, water supply, and
oil extraction.
• The plunger pumps are mainly used for pushing water.
• The piston pump is inbuilt with a piston which is used for pumping the liquid

• The diaphragm pump works similar to plunger pump however it includes diaphragm for suction & expulsion of
liquid.
Construction and working of centrifugal pump

A centrifugal pump is dynamic pump that uses rotational energy to move fluid through a system. Here, we have
to study about centrifugal pump construction and working.

Impeller

• Impeller is a rotor having series of backward curved vanes.
• It is mounted on the pump shaft, which is usually coupled to electric motor or generator.
Casing
• Casing is airtight chamber surrounding the pump impeller.
• It has delivery pipe on one side and suction pipe on other side (called as eye of impeller)
