Centrifugal Pump - Handbook - Free download as PDF File (.pdf), Text File (.txt) or read online for free. This document discusses key concepts related to centrifugal pumps including: 1) Vapor pressure is the pressure at which a liquid will boil and is important when selecting pumps and mechanical seals. Cavitation occurs when the suction pressure drops below the vapor pressure.
Feb 26, 2024· Choosing between a centrifugal pump and a reciprocating pump depends on the specific requirements of the application. Both types of pumps have their own advantages and disadvantages, making them suitable for different scenarios. In this article, we will explore the differences between centrifugal and reciprocating pumps, discuss the disadvantages of centrifugal pumps, and delve into the workings of a single acting reciprocating pump.
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
Difference Between Centrifugal and Reciprocating Pump
Centrifugal pumps and reciprocating pumps operate on different principles and are designed for distinct applications. Centrifugal pumps use rotational energy to transfer fluid, while reciprocating pumps use a piston or plunger to create a reciprocating motion. Centrifugal pumps are typically used for high-flow, low-pressure applications, such as water circulation in HVAC systems or irrigation. In contrast, reciprocating pumps are better suited for high-pressure, low-flow applications, such as hydraulic systems or oil drilling.
Disadvantages of Centrifugal Pump
While centrifugal pumps are widely used due to their simplicity and efficiency, they also have some disadvantages. One major drawback of centrifugal pumps is their limited ability to handle high-viscosity fluids. The impeller design of centrifugal pumps is not well-suited for viscous fluids, leading to reduced efficiency and potential clogging issues. Additionally, centrifugal pumps are not ideal for applications requiring high pressure, as they are more suited for moderate to low-pressure systems.
Single Acting Reciprocating Pump Diagram
A single acting reciprocating pump consists of a cylinder, piston, suction valve, discharge valve, and a power source. The piston moves back and forth within the cylinder, creating a vacuum during the suction stroke and pressurizing the fluid during the discharge stroke. The suction valve opens during the suction stroke, allowing the fluid to enter the cylinder, while the discharge valve opens during the discharge stroke, allowing the pressurized fluid to exit the pump.
Reciprocating Positive Displacement Pump
Reciprocating pumps are classified as positive displacement pumps, meaning they deliver a constant volume of fluid per stroke. This characteristic makes reciprocating pumps suitable for applications requiring precise flow control or high pressure output. Positive displacement pumps are known for their ability to maintain a consistent flow rate regardless of changes in system pressure, making them ideal for metering and dosing applications.
Reciprocating Pump Diagram with Parts
The main components of a reciprocating pump include the cylinder, piston, suction and discharge valves, connecting rod, and power source. The cylinder houses the piston, which moves back and forth to create the pumping action. The suction valve allows fluid to enter the cylinder during the suction stroke, while the discharge valve permits fluid to exit during the discharge stroke. The connecting rod connects the piston to the power source, such as an electric motor or engine, to drive the pump.
Indicator Diagram of Reciprocating Pump
An indicator diagram is a graphical representation of the pressure changes within a reciprocating pump during a complete cycle. The diagram typically consists of two curves representing the suction and discharge pressures over time. The area enclosed by the curves represents the work done by the pump per cycle. By analyzing the indicator diagram, engineers can assess the pump's efficiency, performance, and potential issues such as valve leakage or improper timing.
Single Acting Reciprocating Pump Working
The working principle of a single acting reciprocating pump involves a simple yet effective mechanism. During the suction stroke, the piston moves away from the cylinder head, creating a vacuum that opens the suction valve and allows fluid to enter the cylinder. As the piston reverses direction and moves towards the cylinder head during the discharge stroke, the suction valve closes, and the discharge valve opens, forcing the fluid out of the pump. This reciprocating action repeats to continuously pump fluid through the system.

Periodically I would arrive and the electricians would say they had already checked rotation by running the pump. They would say that “rotation was all good because there was flow when we test-ran the pump”. .
