Understanding Pumps

A pump is a device that moves liquids or slurries by increasing pressure and adding energy to the system. Pumps are generally classified into two types: positive displacement and dynamic, each serving different functions based on their design and application.

What is the primary function of a pump?

• To filter impurities

• To cool gases

• To move liquids or slurries

• To heat liquids

How do pumps move liquids from lower to higher pressure?

• By reducing energy in the system

• By adding energy to the system

• By changing the liquid's color

• By increasing the liquid's temperature

Which of the following is NOT a type of pump classification?

• Positive displacement

• Rotary

• Dynamic

• Static

What is a characteristic of positive displacement pumps?

• They are used only for gases

• They move a fixed amount of fluid per cycle

• They operate at constant speed

• They do not require energy input

Dynamic pumps are best described as:

• Pumps that use a piston to move fluid

• Pumps that rely on velocity to move fluid

• Pumps that only work in a vacuum

• Pumps that do not move fluid
