Mechanical seals are used today in large parts of the process industry and are designed specifically for rotating applications such as pumps, turbines, compressors, and agitators. They are therefore often a critical part of the production equipment and in pump systems, for example, a secure seal between the shaft and the housing is always required. Mechanical seals should also be inspected regularly to avoid fluid leakage and prevent the ingress of foreign bodies. In the worst case, failure to maintain mechanical seals can lead to production stoppage and/or a contaminated end product.
Mechanical seals can be used for units from many different manufacturers. We carry mechanical seals in many material combinations that are compatible with spare parts from some of the most widely used manufacturers such as APV®, Alfa-Laval®, Fristam®, Inoxpa®, Hilge®, IBEX®, SSP®, Johnson®, Jabsco®, Grundfos-Sarlin® and Flygt®. In addition, they come in various combinations such as carbon/rust-free, carbon/cer, sic/sic and tc/tc and are in the vast majority of cases food approved. The rubber material often used in mechanical seals comes in either NBR, EPDM, FPM or PTFE.
When choosing a mechanical seal, several things should be considered:
Different operating conditions require different sealing solutions. For example, in the chemical and pharmaceutical industries, both corrosive and toxic production conditions may be encountered. And in the food industry, mechanical seals and the seals that go with them must also be able to withstand CIP cleaning. At the same time, safety, emission levels and hygiene requirements are high.
We stock several variants of mechanical seals for different manufacturers. They all meet OEM specifications. The wide range is put together so that we can supply mechanical seals for the majority of pumps used in the process industry within a short time - whether it is for the production of food or pharmaceutical products.
Whether it's mechanical seals for different types of pumps, scraper exchangers or something else entirely, it's likely to be in our extensive stock range. And even if your particular mechanical seal happens to be out of stock, there's a good chance we can get it to you within a short time through our close cooperation with manufacturers.
