Applications of G10 in the Mechanical Seal Industry

1. Seal Ring Support and Spacer Components

In mechanical seal structures, G10 can be used as support rings and isolation sleeves for seal rings, replacing metal or certain engineering plastics.

Advantages: non-conductive, corrosion-resistant, and able to withstand certain pressure and friction.

2. Wear-Resistant and Medium-Resistant Liners

Since G10 is made of epoxy resin and glass fiber, it provides excellent resistance to oil, water, and certain chemicals, making it suitable as liner or gasket material in mechanical seals.

In pumps and compressors, it helps resist wear and maintain proper clearance.

3. Insulation Sealing Applications

In motor pumps, submersible pumps, and petrochemical equipment, where sealing components must withstand pressure while providing electrical insulation, G10 is often used as an insulating spacer ring or auxiliary part in end-face seals.

4. Alternative to Metal or Ceramic Parts

In some cases, traditional metal parts are prone to corrosion in chemical media, while ceramic parts are brittle. G10 offers a balance of mechanical strength and chemical resistance, making it a cost-effective alternative.

Why G10 is Suitable for Mechanical Seals

High mechanical strength: Withstands pressure and friction generated by rotating shafts and sealing surfaces.

Dimensional stability: Minimal deformation even in environments with varying humidity.

Chemical resistance: Suitable for water, oil, and certain chemical media.

Lightweight: Lighter than metals, reducing load on bearings and structures.

Electrical insulation: Prevents electrochemical corrosion in electromechanical equipment such as motor pumps.

Typical Application Scenarios

Pump seals (clean water pumps, chemical pumps)

Compressor mechanical seals

Petrochemical equipment (oil-resistant and mild acid/alkali-resistant sealing parts)

Motor pumps / submersible pumps (sealing components requiring insulation)
