Cartridge seals

This article will explain what a mechanical seal is and the key design features that make them work. A mechanical seal is simply a method of containing fluid within a vessel typically pumps, mixers, etc. To address this challenge there needs to be a seal between the shaft and the pump housing that can contain the pressure of the process being pumped and withstand the friction caused by the shaft rotating. Before examining how mechanical seals function it is important to understand other methods of forming this seal. One such method still widely used is Gland Packing. Gland packing is a braided, rope like material that is packed around the shaft - physically stuffing the gap between the shaft and the pump housing. Gland packing is still commonly used in many applications, however increasingly users are adopting mechanical seals for the following reasons;.

One of the main reasons to switch to mechanical seals is the drastic reduction in leakage, which in the long term, saves maintenance valuable time and money. Mechanical seals are devices that seal machines between rotating parts shafts and stationary parts pump housing and are an integral part to the pump. Their main job is to prevent the pumped product from leaking into the environment and are manufactured as single or double seals. What's the difference between the two? Between these two surfaces is a fluid film generated by the pumped product. This fluid film prevents the mechanical seal from touching the stationary ring. An absence of this fluid film dry running of the pump results in frictional heat and ultimate destruction of the mechanical seal.

Home Services Spare parts Original pump spare parts Sulzer mechanical seals. Cartridge seals TSB mechanical seals for reliable operation and fast and easy maintenance. The cartridge seal forms one solid unit having its own sleeve, fixing flange, seal faces, springs and all necessary O-rings, gaskets, setting clips and fixing crews. By the setting clips, the cartridge seal is set radially and axially in the right location during assembly.

Power machines that have a rotating shaft, such as pumps and compressors, are generally known as "rotating machines. They are used in various applications ranging from automobiles, ships, rockets and industrial plant equipment, to residential devices. Mechanical seals are intended to prevent the fluid water or oil used by a machine from leaking to the external environment the atmosphere or a body of water.

Mechanical seals ensure that pumps do not leak, which can cause damage to the rest of the machine.
