The next pump performance curve is the efficiency curve. All the charts shown here are plotted for a constant speed fixed diameter impeller pump. From this chart, you can see that initially, pump efficiency will increase and reach a maximum and then decrease with increasing flow rate. ...
or m of water - at which a pump can no longer exert enough pressure to move water. At this point, the pump may be said to have reached its "shut-off" head pressure. In the flow curve chart for a pump the "shut-off head" is the point on the graph where the flow rate is zero...
Cooling module enables continuous operation throughout the flow curve with fluid temperatures up to 90°C. Use of the module requires 8 SCFM of air at 30 psi air supply. Dimensions PCA300 Controller Power Supply PCA300 Dimensions [mm] inches...
As the pump is sized on the basis of the highest possible flow, it is important always to have the duty point to the right on the efficiency curve (eta) in order to keep efficiency high when the flow drops. 4. Pump Material The material variant should be selected based of the liquid ...
Utilize the system curve and the pump performance curve to select the proper pump for a particular application. Viscosity - Absolute (Dynamic) vs. Kinematic Vicosity is a fluid's resistance to flow and can be valued as dynamic (absolute) or kinematic. Viscosity Converting Chart Convert betw...
A centrifugal pump that is sized in the “sweet spot” of the performance curve can be a game-changer for cooling systems across a wide variety of industries. When the required motor power is one horsepower or less, choosing a centrifugal pump rather than a gear, lobe...
When the type selection is conducted, the performance curve table for clear water of a pump shall be referred to, and the coefficient of range for the flow selected is as follows: 4.1 M, AH type pumps 4.1.1 For slurry of high density and strong abrasiveness, the coefficient...
By selecting a pump, the pump curve appears instantly. In one of the duty charts, a pump curve with hydraulic efficiency is immediately visible. Is the graph with the hydraulic efficiency not visible? Then click on the tab “Chart settings” and check that the checkmark next to “Show ...
