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 through the system efficiently.

Characteristic Curve of Reciprocating Pump
Reciprocating pumps are positive displacement pumps that use a piston or diaphragm to displace a specific volume of liquid with each stroke. The characteristic curve of a reciprocating pump shows the relationship between the flow rate and the discharge pressure. Reciprocating pumps operate by creating a pulsating flow, which can be advantageous in certain applications where a steady flow is not required.
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 refinery service. These standards ensure that reciprocating pumps meet certain design and performance criteria to ensure safe and reliable operation in demanding environments.
Positive Displacement Pumps Diagram
Positive displacement pumps, including reciprocating pumps, operate by trapping a specific volume of liquid and displacing it through the system. This results in a constant flow rate regardless of the discharge pressure. A diagram of a positive displacement pump illustrates how the pump works by showing the movement of the piston or diaphragm as it displaces the liquid.
Centrifugal Pump vs Reciprocating Pump
Centrifugal pumps and reciprocating pumps are two common types of pumps used in various industries. Centrifugal pumps operate by using a rotating impeller to create a centrifugal force that moves the liquid through the pump. They are ideal for high-flow, low-pressure applications. On the other hand, reciprocating pumps use a piston or diaphragm to displace the liquid, making them suitable for high-pressure, low-flow applications.
Indicator Diagram of Reciprocating Pump
The indicator diagram of a reciprocating pump is a graphical representation of the pressure inside the pump cylinder during the pumping cycle. It shows the relationship between the volume of liquid displaced and the pressure generated by the pump. The indicator diagram can help engineers analyze the performance of the pump and identify any inefficiencies in the system.
Single Acting Reciprocating Pump Working
A single-acting reciprocating pump operates by using a piston that moves back and forth in a cylinder to displace the liquid. During the suction stroke, the piston moves away from the inlet valve, creating a vacuum that draws the liquid into the cylinder. In the discharge stroke, the piston moves towards the outlet valve, forcing the liquid out of the pump. This simple yet effective design makes single-acting reciprocating pumps reliable and easy to maintain.
Characteristics of Reciprocating Pump
Reciprocating pumps have several key characteristics that make them suitable for specific applications. These pumps provide a constant flow rate regardless of the discharge pressure, making them ideal for dosing and metering applications. Reciprocating pumps can also handle high-viscosity fluids and abrasive materials, making them versatile in various industries such as oil and gas, chemical processing, and water treatment.
