Viscosity is influenced by load, temperature, water, contaminants and chemical change. The OEM operation manual should be consulted for recommendations on viscosity, but it is also important to measure the oil sump operating temperature since viscosity decreases as temperature increases.

Centrifugal pumps are widely used in various industries for the transportation of fluids. One of the key tools used in understanding the performance of a centrifugal pump is the centrifugal pump chart. In this article, we will delve into the different aspects of the centrifugal pump chart, including efficiency curves, pump performance curves, and how to interpret them for optimal pump selection and operation.
The first curve under pump performance characteristic is the head Vs. flow rate curve. It is also known as a pressure vs. quantity curve. To draw this curve head is plotted on Y-axis, and the flow is plotted on X-axis. You can see the sample HQ curve in the image here. Now let’s convert this curve to a word so that
Efficiency Curve
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 the efficiency of the pump at different flow rates and head conditions. The efficiency curve is crucial in determining the overall effectiveness of the pump in converting input power into useful work output.
Centrifugal Pump Catalogue
A centrifugal pump catalogue is a comprehensive document that provides detailed information about various centrifugal pump models offered by a manufacturer. It typically includes specifications, performance curves, dimensions, materials of construction, and other relevant details. Engineers and buyers refer to centrifugal pump catalogues to select the most suitable pump for their specific application requirements.
Centrifugal Pump Size Guide
Choosing the right size of a centrifugal pump is essential for optimal performance and efficiency. A centrifugal pump size guide helps in determining the appropriate pump size based on factors such as flow rate, head pressure, fluid properties, and system requirements. By following a centrifugal pump size guide, engineers can ensure that the selected pump meets the demands of the application without operating beyond its capacity.
Centrifugal Pump Dimensions PDF
Centrifugal pump dimensions are critical for installation and integration into a system. A centrifugal pump dimensions PDF provides detailed drawings and measurements of the pump, including overall dimensions, inlet and outlet sizes, mounting requirements, and clearance specifications. Engineers and technicians use centrifugal pump dimensions PDFs to plan for pump placement, piping connections, and equipment layout.
Centrifugal Pump Selection Chart
A centrifugal pump selection chart is a graphical representation of pump performance data that helps in comparing different pump models based on their efficiency, flow rates, and head capacities. By referring to a centrifugal pump selection chart, users can identify the most suitable pump for a specific application by matching the required operating conditions with the pump's performance characteristics.
Centrifugal Pump Coverage Chart
The centrifugal pump coverage chart provides an overview of the operating range of a pump in terms of flow rates and head pressures. By analyzing the pump coverage chart, users can determine the maximum and minimum flow rates and head capacities that the pump can handle efficiently. This information is crucial for ensuring that the pump operates within its design parameters to achieve optimal performance and longevity.

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
Furthermore, compared to reciprocating pumps, centrifugal pumps have uniform torque and output and are safe to be used at high speeds. Also, centrifugal pumps have higher capacity and it can also be increased if the inlet and outlet diameters are made larger. 4. Efficiency:
