This difference is the result of the design of both pumps. No internal motion occurs to displace the fluid inside a centrifugal pump. The impeller simply keeps spinning the fluid if the valve is closed. In a PD pump—such as a piston pump—the displacing motion acts on the fluid, and the fluid must exit the pump.
Centrifugal pumps play a crucial role in various industries, including oil and gas, water treatment, and manufacturing. Understanding the terminology associated with centrifugal pumps is essential for proper operation, maintenance, and troubleshooting. In this article, we will explore centrifugal pump terminology in a PDF format, covering important aspects such as design features, efficiency factors, and technical specifications.
Centrifugal pumps can handle a maximum viscosity similar to 30 weight oil at room temperature. Above this viscosity a positive displacement pump should be used Volute / Casing Housing
Design Features
One key design feature of a centrifugal pump is the incorporation of two cut waters to prevent shaft deflection when the pump is operating off of the Best Efficiency Point (B.E.P.). This design element helps maintain the alignment of the pump shaft and impeller, ensuring smooth operation and minimizing wear and tear on critical components. However, it is important to note that having two cut waters can lower the efficiency of the pump, especially when operating at non-optimal conditions.
Efficiency Factors
Efficiency is a critical performance parameter for centrifugal pumps, as it directly impacts energy consumption and operating costs. When a centrifugal pump operates away from its B.E.P., efficiency can decrease due to factors such as increased internal recirculation, higher hydraulic losses, and reduced impeller effectiveness. It is essential for pump operators to monitor efficiency levels and make adjustments to ensure optimal performance and energy savings.
Technical Specifications
Centrifugal pump technical specifications are outlined in detailed catalogues and manuals provided by manufacturers. These documents contain information on pump size, flow rates, head capacities, materials of construction, and operating conditions. Engineers and maintenance personnel rely on these specifications to select the right pump for a specific application, install it correctly, and troubleshoot any issues that may arise during operation.
