Pump coupling types

What are the main types of coupling? What is fluid coupling or hydraulic couplings? Being more rigi their misalignment capabilities are not as great as elastomeric couplings , so alignment of the motor and pump shafts is more critical.

Disc couplings are extremely uniform in design and can rotate at high speeds. Pumps operating at high RPMs are good applications for these well-balance smooth operating devices that, like elastomeric couplings , require no lubrication.

Elastomeric couplings are the most common coupling used today. Grid couplings are most likely found on big pumps with large motors. The picture on the left shows a split coupled inline pump. A close-up of the interior coupling mechanism is shown on the right.

Oversizing a coupling can result in a reduction in needed flexibility or misalignment compensation, and a coupling that is too large can put additional stresses on the pumps and motors being coupled. This is a solid metal coupler that connects the pump shaft to the motor shaft. If shaft misalignment occurs between the driver and the pump as a result of, for example, temperature fluctuations in the fluid handled (on heat transfer and hot water pumps ), the double-cardanic coupling type design is often employed.

Shaft coupling : Double-cardanic coupling.

To reduce the transmission of shock loads from one shaft to another by using flexible couplings. Other coupling types include meshing tooth, or Hines, designs, pin and bush couplings , and spline couplings. You can also choose from rigid.

As well as from nonstandard. Coupling Applications and Industries. And whether types of pump coupling is aluminium , steel , or stainless steel. There are 4types of pump coupling suppliers, mainly located in Asia. There are various types of constant-velocity (CV) couplings: Rzeppa joint, Double cardan joint, and Thompson coupling.

Clamp or split-muff coupling. In this coupling , the muff or sleeve is made into two halves parts of the cast iron and they are joined together by means of mild steel studs or bolts. Pump application conditions affect both the type and size of shaft couplings required. When selecting a coupling type, the engineer must consider a number of factors, such as ease of pump. After spending money on a powerful new pump and the motor to run it,the next big decision is how to connect the two in a way that maximizes their efficiencies and protects them from normal wear and tear.

There are pump adapter kits, pto quick couplings and motor adapters for select pumps. They are suitable for rotary pumps only. Flexible couplings, which are used for most horizontal pump applications, may be separated into three basic types , mechanically flexible, material-flexible, and non-contact magnetic.

Mechanically flexible couplings compensate for misalignment between two connected shafts by means of clearances incorporated in the design of the coupling. Both of these have blades mounted inside at a certain angle. The pump is mounted on the end of driver shaft while the turbine on the driven shaft. The fluid enters into the pump through its centre and when the driver shaft rotates, due to centrifugal force it is pushed outwards. A coupling manufacturer produced a line of wear-free disc pack couplings to meet the API 6requirements for centrifugal pump packages.

These API-610-compliant disc pack couplings are designed to be reliable and wear and maintenance free. The company’s engineers intended to improve the existing methodology. In a fire pump arrangement, it is installed between the pump and rotating motor to act as a power transmitter between the two.
