Understanding Reciprocating Pumps

The video tutorial explains two main types of reciprocating pumps: piston pumps and diaphragm pumps. These pumps operate by using a reciprocating piston or diaphragm to move liquid through a pumping chamber. The liquid enters through an inlet valve and is expelled through an outlet valve, driven by the action of the piston or diaphragm.

Which of the following is a type of reciprocating pump?

• Gear pump

• Peristaltic pump

• Centrifugal pump

• Piston pump

What component is used in the operation of both piston and diaphragm pumps?

• Vane

• Rotating impeller

• Reciprocating piston or diaphragm

• Screw rotor

How does the liquid enter the pumping chamber in reciprocating pumps?

• Through a rotating impeller

• Via an inlet valve

• Via a centrifugal force

• Through a screw mechanism

What is the role of the outlet valve in a reciprocating pump?

• To filter the liquid

• To allow air to escape

• To push the liquid out of the chamber

• To mix the liquid

In a reciprocating pump, what action causes the liquid to be pushed out?

• The rotation of the impeller

• The reciprocating action of the piston or diaphragm

• The spinning of the rotor

• The movement of the vanes
