reciprocating pump vs centrifugal pump|characteristic curve of reciprocating pump : convenience store Aug 21, 2019 · Reciprocating pumps can be more efficient than centrifugal pumps, if they are used in the correct application. Reciprocating machines are … In a centrifugal pump, fluid enters into the casing, falls on the impeller blades at the eye of the impeller, and is whirled tangentially and radially outward until it leaves the impeller into the diffuser part of the casing. the decision to pull a pump out of service for maintenance/repair should be made after a detailed analysis of the symptoms and root causes of the pump failure.

Centrifugal Pump is the most common type of pump in which the impeller is there. When fluid comes into it, the impeller rotates. Here Mechanical energy converts into hydraulic energy.
When we talk about pumps first definition that comes to mind is that it delivers water or other liquid from one place to another place. A pump is a device that is used for lifting the liquid from the ground surface and delivering it to the topmost upper surface. The pump converts mechanical energy into hydraulic
Characteristic Curve of Reciprocating Pump
The characteristic curve of a reciprocating pump shows the relationship between the flow rate and the discharge pressure. It typically exhibits a linear relationship, with the flow rate decreasing as the discharge pressure increases. This curve is essential for understanding the performance of reciprocating pumps under various operating conditions.
API 675 vs 674
API 675 and API 674 are both standards established by the American Petroleum Institute (API) for reciprocating pumps used in the oil and gas industry. API 675 focuses on metering and process pumps, while API 674 covers reciprocating pumps for general refinery service. These standards ensure that reciprocating pumps meet specific requirements for design, materials, and performance.
Positive Displacement Pumps Diagram
Positive displacement pumps operate by trapping a fixed amount of fluid and displacing it through the pump. This results in a continuous flow of fluid, making positive displacement pumps ideal for applications requiring precise flow control. A diagram of a positive displacement pump illustrates the internal components responsible for this pumping action.
Centrifugal Pump vs Reciprocating Pump
Centrifugal pumps and reciprocating pumps are two common types of pumps used in various industries. Centrifugal pumps rely on the rotation of an impeller to create centrifugal force and move fluid, while reciprocating pumps use a piston or diaphragm to displace fluid through a series of back-and-forth movements. Each type of pump has its advantages and limitations, making them suitable for different applications based on factors such as flow rate, pressure requirements, and fluid viscosity.
Indicator Diagram of Reciprocating Pump
An indicator diagram of a reciprocating pump provides a graphical representation of the pressure changes within the pump cylinder during the pumping cycle. This diagram helps engineers analyze the performance of the pump, identify inefficiencies, and optimize its operation. By studying the indicator diagram, operators can make adjustments to improve the overall efficiency and reliability of the reciprocating pump.
Single Acting Reciprocating Pump Working
A single-acting reciprocating pump operates by using a single piston or diaphragm to displace fluid. During the suction stroke, the piston moves away from the pump chamber, creating a low-pressure zone that allows fluid to enter. In the discharge stroke, the piston moves towards the pump chamber, forcing the fluid out through the discharge port. This simple yet effective design makes single-acting reciprocating pumps suitable for various applications requiring moderate flow rates and pressures.
Characteristics of Reciprocating Pump
Reciprocating pumps exhibit several key characteristics that distinguish them from other types of pumps. These include high efficiency, the ability to handle high pressures, precise flow control, and suitability for high-viscosity fluids. Reciprocating pumps are also known for their robust construction and reliability in demanding industrial environments. Understanding these characteristics is crucial for selecting the right pump for specific applications and ensuring optimal performance.
It is a positive displacement type pump where a certain volume of liquid is entered in closed volume and discharged using pressure to the
