Q3. What is pump and types
Ans. 
A pump is a mechanical device used to move fluids from one place to another. There are different types of pumps based on their working principle and application.
• Types of pumps include centrifugal pumps, positive displacement pumps, and specialty pumps like diaphragm pumps and peristaltic pumps.

• Centrifugal pumps work by converting rotational energy into kinetic energy to move the fluid.

• Positive displacement pumps trap a...read more

Q1. What is the difference between centrifugal pump and reciprocating pump
Ans. 
Centrifugal pumps use impellers to move fluid while reciprocating pumps use pistons or diaphragms.
• Centrifugal pumps are more commonly used for high flow rate and low viscosity fluids while reciprocating pumps are used for low flow rate and high viscosity fluids.

• Centrifugal pumps are generally less expensive and require less maintenance than reciprocating pumps.

• Reciprocating pumps are better suited for applications wher...read more
