The different types pump couplings are important components in keeping your pump equipment functioning as efficiently as it should be. That’s where Cotter Marketing can help. By offering exclusive products in Ireland, from well-known industrial couplings manufacturers, we’re able to help you identify the right solutions for your specific plant’s needs.
There are many different types of couplings for various applications, so it helps to have an understanding of what they are and why you need them. These small components connect shafts together, typically pump shafts to motor shafts, thereby enabling the motor to transmit power to the connected pump. Couplings consist of hubs, gears, or springs made of various materials, including synthetic rubbers and metals.
No matter whether you’re looking for marine flexible prop shaft couplings, drive couplings, shaft couplings, flexseal couplings, hydraulic pump drive couplings, or any other type of hydraulic couplings and accessories, get in touch with Cotter Marketing to have a friendly team member consult with you to identify your options.

Pump couplings are relatively inexpensive when compared to the machinery to which they’re applied, but that certainly doesn’t mean you should cut back on their quality. Couplings transmit torque and therefore need to be selected for their suitability for bearing potentially high torque as well as gradual wear and tear on your equipment.
One of our reputable suppliers, CTB Wood’s, carries many flexible coupling products. Here are some of these products:
An industry favourite, the Sure-Flex Plus Couplings are certainly flexible couplings known for their ability to absorb shock, end floating, and misalignments that may occur. The coupling design is clean and simple and is made of EPDM and Neoprene and thus these types of pump couplings require no lubrication and no maintenance.
Its features are as follows:
General industrial applications and pump processes are handled with ease with products like the Torsiflex-I Disc Couplings. This all-metal disc coupling design is sleek and built to be installed and removed easily. It doesn’t require lubrication, yielding less ongoing maintenance over time.
Its features are as follows:
The Dura-Flex Couplings are an ideal flexible coupling solution for a wide range of industrial applications. The sleek coupling design permits superb flex life, even under demanding heavy duty shock loads. This product is available in many different sizes and configurations.
Its features are as follows:
One of the most common ways to determine coupling size for different types of pump couplings involves the use of a calliper.
Firstly, insert the inner tips of the calliper within the bowl of the coupling. Next, expand the calliper tips until they’ve reached the full diameter of the bowl. This will yield the correct dimension for the type of pump coupling desired.
Shaft couplings are used to connect two shafts end-to-end. This enables the coupling to transmit power. Normally, couplings prevent you from disconnecting shafts whilst the machinery is in operation, but some couplings are capable of limiting high torque and can be disconnected when a torque threshold has been exceeded.
Rigid couplings suffer from being limited in their application. Since they are rigid, they are unable to accommodate shaft misalignments, thus making them usable only where shafts do not experience significant lateral alignment or angular alignment.
On the other hand, flexible couplings are ideal where skewed alignments are present as they can be installed and thereby compensate for any misalignments between shafts.
Flange couplings are used between two cast iron flanges in order to transmit power at low speeds. These types of couplings make use of the flanges, which hold two cast iron hubs within each shaft. Each flange is connected with bolts, forming a ring, which completes the drive. This allows torque to be transmitted from flange to flange and subsequently to the shaft.
Like gear couplings and disc couplings, grid couplings are designed to meet the demands of high torque applications. The coupling design consists of two shaft hubs, a grid, and a horizontal cover kit. Consequently, grid couplings are an ideal solution for applications where you anticipate shock loading.
While some types of pump couplings are made of various metals, many are made of elastomeric polymers. This flexible coupling material transmits torque well, and the coupling designs tend to take advantage of the elasticity of this material by allowing it to wear out before metal components are affected.
The main cause of coupling failure is selecting the incorrect type of pump couplings for your equipment. This isn’t a one-size-fits-all type of product, so be sure to consult with an engineer or equipment technician to ensure that you’re using the correct type of pump coupling. Coupling failure, in this case, may derive from: lack of lubrication (or excess thereof), excessive misalignments, and unsuitable operating conditions.
Couplings also fail whilst undergoing excessive speeds or when bearing too great a load for what the equipment and/or couplings were designed for.
