Pump Quiz

What is the primary function of a pump?

• To measure pressure

• To move fluids by mechanical action

• To generate electricity

• To filter air

Which type of pump uses electromagnetism to move liquid metal or other conductive liquids?

• Velocity pump

• Electromagnetic pump

• Positive-displacement pump

• Impulse pump

What is a characteristic of positive-displacement pumps?

• They are always submerged in the fluid they pump

• They operate by increasing the velocity of the fluid

• They are primarily used for low-viscosity fluids

• They can theoretically produce the same flow at a given rotational speed regardless of discharge pressure

Which type of pump is known for having rollers that pinch a section of flexible tubing to move the liquid?

• Screw pump

• Gear pump

• Plunger pump

• Peristaltic pump

What is a common application of reciprocating pumps?

• Generating electricity in power plants

• Filtering water in aquariums

• Pumping air in HVAC systems

• Pumping highly viscous fluids like concrete and heavy oils

Which type of pump is typically used to pump engine oil in a motor vehicle?

• Gear pump

• Screw pump

• Rotary vane pump

• Peristaltic pump

What is a hydraulic ram pump primarily used for?

• Pumping water to a higher elevation using hydropower

• Filtering water in ponds

• Generating electricity

• Pumping air into tires

Which type of pump is also known as a centrifugal pump?

• Regenerative turbine pump

• Radial-flow pump

• Axial-flow pump

• Side-channel pump

What is the main advantage of rotary positive-displacement pumps?

• They are primarily used for pumping air

• They are always submerged in the fluid they pump

• They are the cheapest type of pump

• They can handle highly viscous fluids with higher flow rates as viscosity increases

What is the purpose of a relief or safety valve in a positive-displacement pump?

• To measure the pressure of the fluid

• To filter the fluid being pumped

• To prevent the pump from operating against a closed valve on the discharge side AKA a dead head

• To increase the flow rate
