When we talk about pumps, the 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 energy to move fluids. There are various types of pumps available in the market, each designed for specific applications. Two common types of pumps are reciprocating pumps and centrifugal pumps. In this article, we will explore the key differences between reciprocating and centrifugal pumps.

Positive Displacement Pumps Diagram
Positive displacement pumps are a type of pump that operates by trapping a fixed amount of fluid and then forcing that trapped volume into the discharge pipe. This type of pump creates a constant flow regardless of the discharge pressure. The diagram of a positive displacement pump shows how the fluid is trapped and moved through the pump.
Centrifugal Pump vs. Reciprocating Pump
One of the main differences between centrifugal pumps and reciprocating pumps is the way they move fluids. Centrifugal pumps use centrifugal force to move the fluid through the pump, while reciprocating pumps use a piston or diaphragm to create a back-and-forth motion that pushes the fluid through the pump. Centrifugal pumps are generally used for high-flow, low-pressure applications, while reciprocating pumps are more suitable for high-pressure, low-flow applications.
Indicator Diagram of Reciprocating Pump
The indicator diagram of a reciprocating pump shows the pressure-volume relationship during the pump's operation. This diagram helps in understanding the efficiency and performance of the pump by analyzing the pressure changes at different points in the pump cycle.
Single Acting Reciprocating Pump Working
A single-acting reciprocating pump works by using a piston that moves back and forth within a cylinder. During the suction stroke, the piston moves away from the cylinder head, creating a vacuum that draws fluid into the pump. During the discharge stroke, the piston moves towards the cylinder head, forcing the fluid out of the pump.
Characteristic Curve of Reciprocating Pump
The characteristic curve of a reciprocating pump shows the relationship between the flow rate and the pump's head (pressure) at different operating speeds. This curve helps in determining the pump's performance under various conditions and aids in selecting the right pump for a specific application.
Characteristics of Reciprocating Pump
Reciprocating pumps have several key characteristics that make them suitable for certain applications. These pumps are known for their high efficiency, ability to handle high pressures, and precise flow control. However, they are also prone to wear and require regular maintenance to ensure optimal performance.
API 675 vs. 674
API 675 and API 674 are standards set by the American Petroleum Institute (API) for reciprocating pumps used in the oil and gas industry. API 675 specifically covers metering pumps, while API 674 covers reciprocating pumps for general service. These standards outline the design, construction, and performance requirements for reciprocating pumps in various applications.
Reciprocating Pump Calculation
It is a positive displacement type pump where a certain volume of liquid is entered in closed volume and discharged using pressure to the
Multi-stage centrifugal pumps are a cost-effective and efficient choice for high-pressure applications where the fluid being transferred is relatively clean and free of solids. Their ability to boost pressure over long distances .
