centrifugal pump terminology pdf|centrifugal pump size chart : white label The ability of a pump to purge air from inside its system and creating an area of low pressure that permits water to flow into the pump casing. Centrifugal Self Priming pumps will require an … Centrifugal Pump Reciprocating Pump; It is a type of dynamic pump. It is a type of positive displacement pump. A centrifugal pump uses an impeller for increasing the liquid pressure. A reciprocating pump increases the pressure of the fluid by using a piston. This pump has priming problems. This pump doesn’t have priming problems.

A study on performance characteristics of a centrifugal pump was carried out in the hydraulic laboratory. A half horse power (hp) motor driven centrifugal pump was used.
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.
Resources for Further Learning
For those looking to delve deeper into centrifugal pump terminology and concepts, there are several resources available in PDF format. Free downloads of centrifugal pump textbooks, handbooks, and catalogues can be found online, offering valuable insights into pump design, operation, and maintenance. These resources cover topics such as pump sizing, performance curves, system curves, and troubleshooting techniques, providing a comprehensive overview of centrifugal pump technology.
