How many types of mechanical seals do we have?
The Three Types of Mechanical Seals Three types of mechanical seals are used in process equipment: Cartridge. Component. Air.
What is single and double mechanical seal?
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 is Tandem mechanical seal?
Tandem seals are two single seals mounted in the same direction. Tandem seals are used for toxic or flammable liquids that require a buffer or safety zone. If the inboard seal fails, a high pressure alarm will activate to provide a warning that the inboard seal has failed.
What is single seal?
A single mechanical seal consists of stationary and rotating seal faces that are made from one hard and one softer material. A single mechanical seal offers considerable cost and energy savings when used instead of gland packing.
What is Viton oil seal?
Viton is a synthetic rubber and fluoropolymer elastomer used in O-rings, seals and other moulded products. Genuine Viton® is manufactured from 100% pure fluoroelastomers and is certified with the Viton® certificate.
What is cartridge type mechanical seal?
A cartridge mechanical seal is a completely enclosed seal system with preassembled components. Typically, this seal type is composed of a gland, sleeve, and other hardware that make pre-assembly possible.
What is Buna seal?
Buna O-Rings (NBR, Nitrile) Buna seals are standard in most pumps and work well for most cleaning and fluid pressurizing applications. This form of synthetic rubber is generally chemical-resistant, standing up to oil, fuel, and other harsh compounds.
What size is a seal?
Male gray seals are characteristically larger than females. The average size of a male gray seal is approximately 7-8 feet in length and between 660-770 pounds in weight. Females will average approximately 6.5 feet and between 330-450 pounds in weight. Males’ coloration is typically darker than females’.
What are cartridge seals?
Cartridge seals are designed for rapid installation on and removal from pump shafts. The cartridge seal is an arrangement of seal components on a shaft sleeve and in a seal gland constituting a single unit that is usually assembled and pre-set at the factory.
What is Viton seal?
A Viton™ seal is simply a seal manufactured from Viton™. These seals or gaskets are commonly used to seal leaks, valves, pumps and similar. Viton™ o rings are the most common type of seal, which we provide here at NES in a variety of sizes and profiles.
What is a EPDM seal?
EPDM (ethylene propylene diene monomer) is a complex yet inexpensive rubber that has a wide range of uses. It is commonly used in roofing for waterproofing, as EPDM seals nicely. It is also a common material for freezer room seals, as it is an insulator and has excellent low temperature tolerance.
What color is the seal?
What color is a seal? Depending on the species, the color of a seal’s coat varies from white to gray to brownish black, sometimes with dark or light spots.
What is a Viton seal?
What are the different types of mechanical seals?
Gaskets. Made of flat,elastomeric or similarly flexible material,gaskets are used to fill in the space between the flat surfaces of stationary components in a joint to prevent fluid
What are the parts and types of mechanical seals?
Cartridge
How to select a mechanical seal?
Mechanical seal selection: Choose corrosion-resistant materials and use external mechanical seals. If built-in mechanical seals, the spring surface must be coated with a protective layer. B. high viscosity medium: lubricating oil, gear oil, residual oil, etc. Working condition:
How many types of mechanical seals are there?
Three types of mechanical seals are used in process equipment: Cartridge. Component. Air. A basic mechanical seal contains three sealing points. The stationary part of the seal is fitted to the pump housing with a static seal –this may be sealed with an o-ring or gasket clamped between the stationary part and the pump housing.
