VFDs are used to control the speed of both induction and synchronous motors.
Face treatments increase the opening force by hydrostatic or hydrodynamic methods.
The list of recommended spare parts will depend on the pumping design and other factors.
There are no fixed rules for selecting the pump type for a specific boiler feed application.
How is vibration due to structural resonance avoided in vertical pumps?
The type of driver coupled to a rotodynamic pump can have a significant impact on the pump vibration characteristics.
Metering pumps are characterized by their ability to meet specific performance requirements.
How can pump equipment reliability in wastewater treatment plants be measured and improved?
Not all valves are well suited for controlling system flow rate.
Three-phase alternating current (AC) induction motors are more common for commercial and industrial pumping applications than single-phase motors.
The type of water will influence the material selection and service life.
Digital pressure instruments can be equipped with a transmitter that sends a signal proportional to a data acquisition system.
It commonly occurs in liquid piping systems but may not be noticed in cases where the transient pressure wave is less notable
For pumps, this term generally relates to sealless canned motor pump (CMP) or magnetic drive pump (MDP) types.
There will be some stringy materials and grit but in the headworks portion of the plant.
Viscosity will affect positive displacement and rotodynamic pumps differently.
Yes, friction losses due to bearings can be calculated.
If a higher speed pump is desired, then more attention will need to be paid to the pump’s suction performance.
