To harvest the desired return on investment, the heavy equipment needs to run continuously and without costly breakdowns and unforeseen repair work.Our face seals'long service life is due to the use of chilled cast iron.This class of materials is very hard, resists abrasive wear and corrosion, and has excellent tribological properties.From the first contact with our customers to shipping the finished face seal we take full responsibility.
JCB 05 / 903811 Floating Seal Kit
ZHONO not only offers "off-the-shelf" designs –its engineering team is also available to work with your engineers to design 'non-standard' metal face seals.Whether developing a new seal size or type to fit your application, or utilizing a new metal seal or O-Ring material, ZHONO engineers have the experience necessary to design, procure and test these concepts and follow them to production.No matter what type you need,contact us please.
The DO type Mechanical Face Seal consists of two identical metal face seals and two rubber O - rings placed on the Ramp profile of the metal seal. The O- ring material s however are of 4 types based on the application requirements
The DF Type Mechanical Face Seal consists of two metallic angular seal rings with identical geometrical profiles. As compared to the DO type Mechanical face seals,the resilience of the trapezoid rubber ring is ormally
stiffer. The seal installation does not require an installation tool.
XY type are special designs (versions A and B) including inverted seal rings and designs specifically for applications with extreme mud impact.
Depending on the ambient and operating temperature of the face seal, the O-rings or trapezoidal rings can be made from a choice of four proven basic elastomeric materials in different grades.Each elastomeric material is highly resilient and will show very little permanent set which ensures a reliable static seal and clamping action.
NBR – standard
HNBR – higher temperatures
VMQ(silicone rubber) – covers temperature in both hot and cold extremes
FPM(Fluorine rubber) – extends the maximum temperature while offering excellent oil compatibility
For Years together, ZHONO Mechanical Face Seals have been used by OEMs and Users of Seals with outstanding success in Construction Equipments,Transmission Drives, axles, Rollers and Argo machineries. The Special Alloy Cast iron materials Provided by ZHONO are having extraordinary capacity for wear resistance, for a verity of demanding applications, such as mining machinery, agriculture equipments, undercarriage vehicles, track rollers and many other applications.
Mechanical face seals or called floating seals,duo cone seals,seal group etc, are found wherever the going gets really tough: They seal wheel hubs and axles,the tread, support and guide roller bearings of tracked vehicles, transmissions, and many more axial connections in heavy technical equipment such as construction machinery, conveyors, mining machinery, concrete and cement mixers, tunnel boring, and agricultural equipment. Our portfolio of designs and advanced materials covers applications which include some of the biggest equipment around: We manufacture face seals with a diameter of up to 1,425 mm – in fact the world's largest cast iron face seals.
Our face seals consist of two identical metal seal rings mounted in two separate housings face-to-face on a lapped seal face. The metal rings are centered within their housings by an elastomer element. One half of the Mechanical Face Seal remains static in the housing, while the other half rotates with its counter face.
