O Ring Mechanical Seals WM58U 59U

The China mechanical seals O ring WM58U 59U is a typical large-spring mechanical seal with an internal single-end single-spring non- equilibrium drive of loop transferring spring. It is allowed to adopt various materials and end combinations. It can be used with KSB pump together perennially to meet the wide demands of pumps of various models. Pay attention to the direction of rotation during usage.

Product Description

China mechanical seals O ring WM58U 59U is the simplest mechanical seal gaskets. These doughnut-shaped elastomers seal two or more parts of a mechanism together to prevent leaks. 

O ring mechanical seals can be used to permanently seal two static parts of a fluid passage or create a sealed joint for moving parts of a liquid processing system. They have a cross-section that allows them to be properly fitted and compressed between two mechanical parts. 

China mechanical seals O ring WM58U 59U are the most common type of gasket and are used in many different kinds of machines because they are highly reliable, simple to install, and cost-effective.

Application of China Mechanical Seals O Ring WM58U 59U

Wendong offers a full range of China mechanical seals O ring to suit both general and specialized industrial applications. We currently serve customers in a diverse range of industries, such as:

● Transportation

● Medical

● Oil and gas

● Electronics

● Food and beverage

● Water systems

● Chemical processing and energy

● Fluid power

We offer standard o ring mechanical seals for all general applications, as well as O-rings that conform to specific standards such as:

● Military (Mil-Spec)

● FDA (food-grade)

● Metric

Our list of China Mechanical Seals O Ring WM58U 59U materials includes:

● Buna/nitrile: One of the most common O-ring materials, Buna/Nitrile has high tensile strength and is resistant to corrosion or abrasion.

● Aflas: Aflas offers a combination of temperature and chemical resistance that is appealing for many oils, aerospace, and general industrial uses.

● Butyl: Butyl seals have an exceptionally low permeability to gas leakage, making them valuable for vacuum-sealing.

● Ethylene propylene: Ethylene propylene has largely replaced butyl because it offers similar properties, but with enhanced ozone and chemical resistance.

● Fluorocarbon (Viton®): Used in engines, fuel-handling systems, and another high-temperature, high-exposure situations, fluorocarbon is one of the best all-around O-ring materials.

● Fluorosilicone: Fluorosilicone is ideal for aerospace fueling thanks to its excellent fuel resistance and temperature stability. It is also gaining broader popularity for static sealing.

● Hydrogenated Nitrile: Hydrogenated Nitrile is stronger than standard nitrile while retaining a high level of oil and corrosion-resistance.

● Silicone rubber: Silicone rubber provides excellent temperature resistance and is available in medical grades. It is most useful for static sealing in extreme temperatures.

● Neoprene: Neoprene offers high strength and resistance to various chemicals and temperatures. While a good all-around material, its most widespread use is in refrigerator sealing.

● Polyurethane (cast): Cast polyurethane stands out for its abrasion resistance, making it ideal for high-wear situations.

● Polyurethane (millable): Millable polyurethane features similar characteristics to cast polyurethane, but possesses a slightly lower tensile strength.

● Kalrez: Kalrez is common for oil and gas, chemical processing, and paint applications due to its extreme resistance to volatile chemicals.

● Polytetrafluoroethylene (PTFE): PTFE is another material with broad chemical and temperature resistance, but it requires extra care in the installation process due to its lack of elastic memory at room temperature.
