When the fluid is forced away from the center, or the eye of the impeller, a ____ is created thus resulting to flowing of more liquid.
centrifugal force
positive displacement
vacuum
negative displacement
Type of a centrifugal pump that borrows characteristics from both radial flow and axial flow pumps.
Radial Flow Pump
Mixed Flow Pump
Axial Flow Pump
It is a type of pump casing design that has an offset impeller creating a curved funnel with an increasing cross-sectional area towards the pump outlet which causes the fluid pressure to increase towards the outlet.
vortex
volute
diffuser
rotary
It is used for a wide variety of industrial applications thanks to their increased efficiency and ability to pump fluids at higher pressures.
Multistage centrifugal pumps
Single stage pump
Circulator pump
It is a rotating component of a centrifugal pump that accelerates fluid outward from the center of rotation, thus transferring energy from the motor that drives the pump to the fluid being pumped.
Impeller
Coupling
Shaft
Stuffing Box
Centrifugal pumps can also develop a phenomenon called “cavitation”.
True
False
When the sealing is achieved by means of packing, the chamber is referred to as a ___________.
Stuffing Box
Nozzle
Casing
Seal Chamber
A pump moves fluids from ___ pressure to ____ pressure.
lower, higher
lower, atmospheric
higher, lower
higher, atmospheric
When the sealing is achieved by means of a mechanical seal, the chamber is commonly referred to as a ___________.
Stuffing Box
Nozzle
Casing
Seal Chamber
Type of a centrifugal pump where the liquid enters at the center of the impeller and is directed out along the impeller blades in a direction at right angles to the pump shaft.
Radial Flow Pump
Mixed Flow Pump
Axial Flow Pump
Type of a centrifugal pump where the impeller pushes the liquid in a direction parallel to the pump shaft.
Radial Flow Pump
Mixed Flow Pump
Axial Flow Pump
Multistage centrifugal pump consists of two or more __________.
Impellers
Suction head
Pump
Multistage centrifugal pumps have the following two advantages except ______.
to produce a high head
has higher unbalanced thrust and radial forces at off-design flow rates
to produce a large quantity of liquid
Ferrous particles in liquid are not problematic when you are using magnetic drive.
True
False
Low flow of liquid due to not priming properly cannot lead to overheating of the pump.
True
False
A dead-head is caused when a centrifugal pump operates with no flow through the pump due to a closed discharge valve or blockage in the line.
True
False
Its goal is to ensure that the pump is actually not moving the fluid downstream by confirming that there is no flow downstream or, in the case of liquid centrifugal pumps, the pump is primed or not in air lockup.
True
False
