A pump is a device that raises or transfers fluid. Pumps come in many forms, but can generally be categorised according to two main operating principles: Positive displacement pumps and .

Pump couplings play a crucial role in the operation of centrifugal pumps, serving as the link between the motor or engine (driver) and the pump itself. These mechanical devices are designed to transmit power efficiently while accommodating any misalignments between the driver and the pump. In addition to power transmission, pump couplings also help to reduce the impact of shock loads and vibrations, thereby extending the lifespan of the pump system.

A pump coupling is a mechanical device used to connect two shafts, typically one from the pump’s impeller and the other from the motor or engine. Its primary function is to transmit power while accommodating misalignment, reducing

What is a Pump Coupling?

A pump coupling is a mechanical device that connects the shaft of the motor or engine to the shaft of the pump. It consists of two flanges, one attached to the motor shaft and the other to the pump shaft, which are then connected by a flexible element. This flexible element allows for some degree of misalignment between the two shafts, which can occur due to factors such as thermal expansion, foundation settlement, or manufacturing tolerances.

Oil and Gas Pump Coupling

In the oil and gas industry, centrifugal pumps are commonly used for various applications such as crude oil transfer, water injection, and gas processing. Pump couplings in these applications must be able to withstand high temperatures, corrosive environments, and heavy loads. Couplings used in oil and gas pump systems are often made of high-strength materials such as stainless steel or alloy steel to ensure reliability and durability in harsh operating conditions.

Pump Flange Coupling

One of the most common types of pump couplings is the flange coupling, which consists of two flanges that are bolted together to connect the motor and pump shafts. Flange couplings are simple in design, easy to install, and provide a high level of torque transmission. They are suitable for applications where precise alignment between the driver and the pump is critical, as any misalignment can lead to increased wear and premature failure of the coupling.

Sleeve Coupling Pump

The coupling of centrifugal pump is used to connect the shafts in different mechanisms, mainly through rotation, to transfer the rotating power of the motor to the mechanical parts of the feed pump, so as to achieve the …

Centrifugal pumps work to produce flow or raise a fluid from a lower level to a higher level. The working of these pumps is based on a straightforward mechanism. A centrifugal pump turns .
