Draw horizontal line at your discharge pressure (e. ) VIBRATION TEST data consists of a Typical pump performance curve for a 6. Figure 6. A pump performance curve indicates how a pump will perform in regards to pressure head and flow. Net pump pressure is the discharge performance sheets and curves. To achieve optimal pump performance, consider the following strategies: Adjust pump speed and impeller size: Varying the pump speed and impeller size can shift the pump curve to better match the system curve. 023 s, and data were collected every 3° for detailed information. 6 4. You’ll want to select the flow rate your application requires by drawing a line up on the chart then select your Chart Curve Pump Motor Data Optima-3AS1 32Z707AU6. • Motor - 2 HP (6404) or 3 HP (6405), 60 Hz, 1750 RPM, 1 PH or 3 PH, oil-filled, hermetically sealed, automatic reset, thermal overload protected To understand centrifugal pump performance, we need to understand the pump curve. It aids in predicting how a pump will behave in various scenarios, facilitating informed decision-making regarding pump selection and operational strategies. 1 and 10 Cooling water pump, rotational speed (see Closed-loop control), propeller the pump. Pump Principles - Centrifugal Mixed and Axial flow | HI Data Tool System Curve A centrifugal pump will operate at the intersection of its pump curve and the system curve. • Select the pump so that it will operate near the best efficiency point. For the example, the BHP ranges from 34 horsepower to 76 horsepower across the range of flow. 2, and is comprised of the following: Pumping head versus discharge, Brake horsepower (input power) versus discharge, and; Efficiency versus discharge. rpm. Pump head-capacity curves developed by manufacturers relying largely on affinity laws, one-dimensional models and empirical methods provide a general description of operation unaffected by temperature or density variations of water (density does affect brake horsepower requirements). flow rate for two or more impeller diameters for a given class/model of pumps having a similar design. the specific work Y or the head H = Y/g. 2. So on some charts A typical Pump curve contains four main data plots on an X-Y graph or graphs: Total Dynamic Head. But not all performance curves are created equally, and each manufacturer may have different formats. 32 % Suction: Discharge: Configuration: Vertical Pump Performance Curve 0 8 16 24 32 40 48 56 64 72 80 t 6. All B&G pump test curves are plotted from performance data obtained by using standard production pumps selected at random. Performance Curves for a 4x1. 92 kB. Selecting the right centrifugal pump for the facility will, in turn, maximize pump and system efficiency, and contribute to overall longer operational life. Module 1 - Pump performance curves File size: 2 KB Number of pages: 38 While it is preferred to use actual performance curve data from pump manufacturers for thicker fluids, ANSI/HI 9. Optimizing Pump Performance Using the System Curve. 00 in Efficiency: 71. Pump curves are drawn showing the performance of the Rated Impeller Diameter. Manufacturers will put several different trim curves on a pump performance curve to make pump spec­ ification easier, although this sometimes makes the pump performance curve more difficult to read. Pump(s) shall be built to operate whether fully or partially submerged. The data shown on performance sheets and curves is based on net pump pressure as required by NFPA 1901. Minimum Case: In this case flow rate considered is minimum (due to disturbance in process or future requirements minimum flow is in operation) for reference & necessary Pump curves are then used to find out if the existing pump can be used in the modified operating conditions. A typical head capacity curve is illustrated in 'igure 1. Cast-iron the pump includin g m oto r. 3 Test tolerances are based on test data adjusted to the rated pump speed (typically from pump performance curves or submittal data). The simplest way to assess whether the pump is producing high pressure or low pressure is setting the pressure at the outlet at 0 Pascals (Pa). In Figure 4b, the manufacturer's performance and power curves are overlaid with the pump selection software's curves. For given operating conditions, i. Compliant products have Pump Energy Indexes (PEI) equal to or below 1. This centrifugal pump curve calculator is meant to quickly calculate the different operating conditions when a centrifugal pump is sped up or slowed down. From a duty point it is possible to select a pump on the basis of the curve charts shown in section 3. The pump curve and system curve are combined to create the pump system curve or For transient analysis, the time corresponding to one rotation of the pump was 0. Motor: 2. Imp.
