Figure 1: Back-to-back Double Mechanical Seal Arrangement. In this double seal configuration, two narrow seal faces are mounted back-to-back (opposing) to one another. This is the original concept of a dual seal —taking two component mechanical seals and placing them 'back-to-back' within the stuffing box. This configuration is used in

A twofold mechanical seal can be masterminded either eye to eye or consecutive. The inboard, or "essential seal" keeps the item contained inside the pump lodging. The detachable, or "auxiliary seal" keeps the flush fluid from spilling into the climate. Double mechanical seals are offered in two courses of action :

The benefits of selecting non-cartridge seals for your mechanical seal support systems include: Reduced expenses on initial seal purchase Reduced spares costs as the individual components can be stocked vs. the entire seal Superior adaptability to very small pumps Disadvantages of Non-cartridge Type Mechanical Seals

Mechanical seals use several sealing points and when fitted correctly it should eliminate almost all leakage, making them the best option to avoid leaks and ensure safety from dangerous fluids. The main barrier to uptake for mechanical seals is

Lip seals and Mechanical Packing. Rotary lip seals maintain a thin layer of lubricant between the “lip” and the shaft. The hydrodynamic action created by the 

22 May The purpose of any seal is to protect a joining in a piece of equipment. Seals serve to keep lubrication or other liquids inside and contamination outside of the joint. A lip seal is also known as an oil seal or a rotary shaft seal. Oil seals or rotary shaft seals and mechanical seals are designed for moving parts.

Expert Reply: The difference between the single lip and double lip seals is that the double lip grease seal will have two rubber lips that are in contact with the spindle. The double lip grease seals are usually used in marine applications to give a better seal and protect the bearings from the water, which can cause damage to them.

5/12 · Both lip seals and mechanical seals are used in a wide variety of applications that relate to each other, but there are key differences in both their applications and qualities. The

Basics of fluid pump sealing. A mechanical seal is simply a method of containing fluid within a vessel (typically pumps, mixers, etc.) where a rotating shaft 

Mechanical Seal Information. The advantage of lip seals is that they require very little space. They do have limitations on pressure, speed, minimal, and media compatibility. As long as the application is within the parameters of the materials of construction they can last many years. Mechanical face seals are required when the application is

Reduced Friction Compared to Lip Seals Centritec Seals feature an internal, centrifugal pressure sealing method that allows these seals to operate with much
