Centrifugal Pump Fundamentals - Head - RA Mueller

Centrifugal Pump Fundamentals - Head. The pressure at any point in a liquid can be thought of as being caused by a vertical column of the liquid which, due to its weight, exerts a pressure equal to the pressure at the point in question. ...<< more>>

Troubleshooting pumps – Mc Nally Institute

The centrifugal pump always pumps the difference between the suction and discharge heads. A centrifugal pump always pumps a combination of head and capacity. These two numbers multiplied together must remain a constant. ...<< more>>

Damaging Flow Phenomena: Destructive Factors Determine

If the pump has "Low" suction energy and a NPSHR that increases at low flow rates, the minimum flow rate should be selected to insure that the NPSH Margin Ratio does not go below about 1.1 to 1.3. For "High" and "Very High" suction energy pumps, the minimum flow should insure a NPSH Margin Ratio of at least 3.0 if the pump must be in operated ...<< more>>

What is head? - Pumps! That's what it's about

The plot of total head vs. flow for a centrifugal pump is very typical and it looks like this: Figure 6 Typical curve of total head vs. flow for a centrifugal pump. To buy the correct pump for your application you first have to know what total head you need and at what flow rate . ...<< more>>

Centrifugal pump - Wikipedia

Centrifugal pumps are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. The head added by the pump is a sum of the static lift, the head loss due Overheating due to low flow; Leakage along rotating shaft. ...<< more>>

Centrifugal Pump Flow Operating Regions and Impact on

A pump will always operate at the flow rate where the pump head-capacity curve intersects the system head-capacity curve. This means that it is also critical to accurately determine the true system H-Q curve (see Pump Tips, WW, January 2009 ), in order to establish the true operating flow rates. ...<< more>>

Axial Flow Pumps | Engineers Edge | www.engineersedge

Axial flow pumps can generate 10 to 20 feet of head, lower than most other types of centrifugal pumps. In addition, they are capable of producing flow rates as high as 200,000 gpm. Axial flow pumps can handle some of the highest flow rates of any type of centrifugal pump. ...<< more>>

Reading Centrifugal Pump Curves

Centrifugal pump curves show pressure as head, which is the equivalent height of water head and flow. Pumps can generate high volume flow rates when pumping against low-pressure head or low volume flow rates when pumping against high-pressure head. The possible combi-nations of total pressure and volume flow rate for ...<< more>>

Specific speed - Wikipedia

Radial impellers are generally low flow/high head designs whereas axial flow impellers are high flow/low head designs. In theory, the discharge of a "purely" centrifugal machine (pump, turbine, fan, etc.)is tangential to the rotation of the impeller whereas a "purely" axial-flow machine's discharge will be parallel to the axis of rotation. ...<< more>>
