Our innovative, award-winning mechanical seals for pumps, agitators, mixers, and other rotating equipment simplify installation, improve reliability, and extend the performance of fluid handling. Liquiflo gear pumps can be configured with packing, single or double mechanical seals or magnetic-drive. High quality, fast lead times. Our technologies support the fight against Covid Pump Manufacturers is a website that lists all types of pump manufacturers from around the world.

Mechanical seals

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.

By Mac MacCormack on September 17, After completing a recent training class, I had opportunity to ask our customer what were some of the highest cost failures they experienced. The answer? Mechanical seal failures. Mechanical seals come in a wide variety of configurations and manufacturers. These are very close tolerance and will not withstand misalignment for long if at all. A high percentage of mechanical seal failures are due to vibration induced by misalignment.

These devices preserve the integrity of the pump systems by preventing fluid leaks and keeping contaminants out. Mechanical seal systems are used on various seal designs to detect leakage, control the seal environment and lubricate secondary seals. Depending on the pump type and the process variables, there are various mechanical seal types to choose from. Each seal variant has its unique design and characteristics which make it suitable for a specific application.

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.

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. This role of mechanical seals contributes to the prevention of environmental contamination, energy saving through improved machine operating efficiency, and machine safety. Shown below is a sectional view of a rotating machine that requires the installation of a mechanical seal. This machine has a large vessel and a rotating shaft at the center of the vessel e.

A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Gaskets allow for "less-than-perfect" mating surfaces on machine parts where they can fill irregularities. Gaskets are commonly produced by cutting from sheet materials. Gaskets for specific applications, such as high pressure steam systems, may contain asbestos. However, due to health hazards associated with asbestos exposure, non-asbestos gasket materials are used when practical.
