what is the difference between centrifugal pump and reciprocating pump|single acting reciprocating pump working : distributing Jul 19, 2023 · Centrifugal pumps rely on the centrifugal force created by a rotating impeller to move fluids, making them ideal for high-flow, low-to-medium-pressure applications. On the other hand, reciprocating pumps use a piston or plunger … The flow rate of a centrifugal pump can vary widely depending on the size of the pump, the speed of the impeller, and the specific design of the system. These pumps can achieve flow rates ranging from a few gallons per .

A Centrifugal pump is the reverse of radially inward flow reaction turbine. Work done by water on runner of turbine per sec per unit weight of water = 1 (𝑉 ê1 1 ±𝑉 ê2 2 )
When it comes to pumping fluids in various industries, two common types of pumps that are often compared are centrifugal pumps and reciprocating pumps. Each type has its own set of characteristics, advantages, and limitations. In this article, we will delve into the differences between centrifugal pumps and reciprocating pumps, exploring their working principles, applications, and key features.

Positive Displacement Pumps Diagram
Positive displacement pumps are a category of pumps that displace a specific volume of fluid for each cycle of operation. This type of pump traps a fixed amount of fluid and then forces it into the discharge pipe. Positive displacement pumps are known for their ability to provide a constant flow rate regardless of the discharge pressure.
Centrifugal Pump vs. Reciprocating Pump
One of the fundamental differences between centrifugal pumps and reciprocating pumps lies in their operating principles. Centrifugal pumps work on the principle of centrifugal force, where a rotating impeller accelerates the fluid outward, creating a high-velocity flow. On the other hand, reciprocating pumps use a piston or plunger to displace the fluid by moving back and forth in a linear motion.
Indicator Diagram of Reciprocating Pump
The indicator diagram of a reciprocating pump illustrates the pressure changes that occur during the pumping cycle. It shows the relationship between the volume of fluid being pumped and the pressure within the pump chamber. This diagram is crucial for analyzing the performance and efficiency of reciprocating pumps.
Single Acting Reciprocating Pump Working
In a single-acting reciprocating pump, the piston or plunger moves in only one direction to displace the fluid. During the suction stroke, the piston moves away from the pump chamber, creating a vacuum that draws the fluid into the chamber. In the discharge stroke, the piston moves towards the chamber, forcing the fluid out through the discharge pipe.
Characteristic Curve of Reciprocating Pump
The characteristic curve of a reciprocating pump depicts the relationship between the pump's flow rate and the discharge pressure. This curve helps in determining the pump's performance under varying operating conditions. Reciprocating pumps typically exhibit a steep rise in pressure as the flow rate increases, making them suitable for applications requiring high pressure.
Characteristics of Reciprocating Pump
Reciprocating pumps are known for their ability to generate high pressures and handle viscous fluids with ease. They are ideal for applications where a constant flow rate is required, such as in dosing systems and high-pressure cleaning equipment. However, reciprocating pumps tend to be more complex and require regular maintenance compared to centrifugal pumps.
API 675 vs. 674
API 675 and API 674 are industry standards that define the requirements for reciprocating pumps used in various applications. API 675 focuses on metering and dosing pumps, ensuring accurate and reliable performance for critical processes. API 674, on the other hand, covers general-purpose reciprocating pumps used in a wide range of industries.
Reciprocating Pump Calculation
Unlike centrifugal pumps, which rely on rotation, reciprocating pumps utilise a piston, diaphragm or a plunger to displace the fluid in a controlled manner. This reciprocating …
Centrifugal pumps play a pivotal role in applications ranging from water treatment to agriculture, mining, and oil and gas, where the need for consistent, reliable fluid transfer is paramount. Operating on the principle of converting rotational kinetic energy into hydrodynamic energy, centrifugal pumps ensure that fluids are moved efficiently .
