Valves’ Effect on Flow Rate & Water Hammer - Not all valves are well suited for controlling system flow rate. Overall, the performance and characteristics of each valve will affect the magnitude of any transients developed by valve closures and openings. It is important to consider… more...
Total Head for Pumps & Systems - The term “total head” (H) is used to describe the energy in pumping systems and is how manufacturers represent the performance of their pumps as a function of flow rate. more...
What is Cavitation? - Centrifugal pumps are sometimes used in environments where the pumped product contains suspended solids. While some pumps are specifically designed for solid handling or slurry applications, normal centrifugal pumps do not contain features to prevent performance degradation from the… more...
Wear in Centrifugal Pumps - Centrifugal pumps are sometimes used in environments where the pumped product contains suspended solids. While some pumps are specifically designed for solid handling or slurry applications, normal centrifugal pumps do not contain features to prevent performance degradation from the… more...
Determine Power When Looking at Typical OEM’s Pump Curve - A typical pump curve (Image 1) includes the pump head for various impeller trims as a function flow rate. It also includes lines of constant efficiency, power and NPSH3. more...
Considerations for Wastewater Pumps - The vertical turbine pump is a trusted and proven workhorse pump found in industrial environments around the world. This pump design is continually improving operations in key global industries such as oil and gas, petrochemical, chemical, power,… more...
Visualization of Gas-Liquid Flow Pattern in a Centrifugal Pump - The centrifugal pump is extensively used in the fields of petroleum, chemical industry, nuclear power, agriculture, etc. The bubble flow is an important flow pattern that exists in the working process of a centrifugal pump. more...
Paradigm Shift Towards Solar Powered Centrifugal Pumps - Ideally, a centrifugal pump should be operated at or near its best efficiency point (BEP) flow rate in order to minimize the life cycle costs. However, all centrifugal pumps have sweet spots beyond the BEP that will… more...
Centrifugal Pump Flow Operating Regions and Impact on Reliability - Ideally, a centrifugal pump should be operated at or near its best efficiency point (BEP) flow rate in order to minimize the life cycle costs. However, all centrifugal pumps have sweet spots beyond the BEP that will… more...
What is a Centrifugal Pump? - Every centrifugal pump includes an assembly of mechanical components that make operation of the pump possible. more...
