Regarding the selection of buffer pads for pump couplings
Thread Content
The factory has dozens of various water pumps and oil pumps. When the cushioning pads between the couplings get damaged, they need to be replaced. However, in recent years I’ve encountered quite a few problems when buying such cushioning pads. If I’m lucky, they can last for several years without any issues; but if I’m not so lucky, I end up with low-quality ones that break after just two months (it’s not likely to be a problem with installation or adjustment, as all units from the same batch break within a short time). I would like to ask the experts here: what material is best for making cushioning pads that are durable? It doesn’t matter if the price is higher. Also, are there any brands whose cushioning pads are of better quality? Looking for recommendations. . .
Polyurethane will work fine; once the alignment is corrected, things will improve a lot.
JBT10466 specifies technical requirements for elastic blocks; polyurethane is an excellent material, as it is crucial for reducing vibrations and increasing the mass of the counterweight.
……Switch to a coupling with a belt connection – it’s very durable :) But if there are many pumps and all of them are replaced, the cost will be high; you could opt for some that are more prone to breaking and give those a try first
When selecting pump coupling buffers, the following aspects can be considered: 1. Material selection: Common materials for buffers include rubber, polyurethane, etc. Generally speaking, polyurethane cushioning materials have better wear resistance and corrosion resistance, making them suitable for various operating conditions. Rubber cushioning pads are relatively common, but their service life may be affected. 2. Strength requirement: The operating parameters and working conditions of different pumps may vary; therefore, the appropriate strength of the cushioning pad should be selected based on the actual circumstances. Generally, buffer pads come in different specifications and hardness levels; when selecting them, it is necessary to make a suitable match based on factors such as the pump’s power, speed, and operating environment. 3. Brand selection: There are some well-known brands of pump coupling buffers available on the market, such as SKF, Schaeffler, etc. These brands are relatively reliable in terms of quality and technology, and they can be considered as options. Ultimately, it is still recommended that you have detailed discussions and consultations with the supplier before making a purchase, to learn about the product’s specifications, materials, etc., and to ask the supplier for certification of compliance and relevant quality guarantees. .

Where can I buy this imported polyurethane? What brand?
Buffers of poor quality really don’t work; even if there are no issues with alignment, variable frequency is better than fixed frequency.
