Choosing the Right Types of Mechanical Seals You can easily choose mechanical seals from a variety of alternatives available today. Each seal type is specifically designed to work in a certain type of environment. One of the first things you need to do before you start your project is to smooth out all of your requirements, seal specifications included. The Benefits of Each Mechanical Seals Type To help you with your selection, we outline here some of the more common seal types and their advantages: 1. Pusher Seals – These employ secondary seals which move along the shaft of the machine they are attached to. This assembly design keeps the seal face in contact with the shaft at all times. It also allows the seal to last a little longer than usual. Pusher seals are inexpensive to use compared to other seal variants. They are also known to work very well in different conditions and they come in a variety of configurations. 2. Unbalanced Seals - Another seal type that is cheap to acquire is the unbalanced seal. They are used mostly because they are easy to maintain and are more secure. They are very stable when used in conditions that experience vibrations, cavitations, and misalignments. However, they can only be used within a certain pressure limit. 3. Non-pusher Seals – These differ from the pusher type because they do not require a movement along the sleeve to maintain contact between itself and the machine parts. This type can withstand extreme temperatures and can work just fine even without the aid of a secondary seal. 4. Balanced Seals - The most common among all the seal types. They are very easy to install and require very little maintenance. This type is very versatile since it functions well withstand varying amounts of pressure. They have lower seal face loading compared to other types and produce lesser heat when used. 5. Cartridge Seals - The normal routines entailed when using normal mechanical seals are not necessarily needed when you opt to use a cartridge seal. They do not require regular check-ups because they are presumed to be less error prone than their counterparts. Adjustments when using cartridge seals are also very easy to do. They do not require you to disassemble the whole assembly to do it. Proper Maintenance of Mechanical Seals To check for leaks in seal installations, look out for drops during use. Make sure the arrangement does not exceed three drops every 15 minutes. If it does, make the necessary adjustments in the machine or the seal itself. Seal failures can be caused various circumstances. The most common among them is mismatching. Mismatching seals can cause a lot of errors. Be sure to check the seal dimensions and surfaces first before you proceed with your project. Regular maintenance is encouraged when dealing with seals, gland packing or similar gaskets. Problems with regards to seals are very easy to fix. Maintaining your mechanical seals in tip-top shape is a very important part of your operations.
