Standard Rubber Bellows Mechanical Seal WM202

A China standard rubber bellows mechanical seal WM202 consists of two seals arranged in a series. The inboard, or “primary seal” keeps the product contained within the pump housing. The outboard, or “secondary seal” prevents the flush liquid from leaking into the atmosphere.

Product Description

China standard rubber bellows mechanical seals are important parts of pumps. Good quality rubber mechanical seals can reduce the frequency of pump maintenance. Our advanced equipment and rigorous machining make the mechanical seal more oil resistant, pressure resistant, wear-resistant, elastic and high strength.

Standard rubber bellows mechanical seal is used for plain shafts, these are single coil Unbalanced seals having elastomer bellows and are Independent of direction of rotation. Rubber provides the secondary seal between each seal face and adjacent seal face. 

Advantages of China Standard rubber bellows mechanical seal WM202

● Outboard seal provides full pressure back-up

● Short axial length

● Unified face alignment (less possible in the tandem configuration)

● Non-fretting

● Reverse pressure balanced if double-balanced

● Available in cartridge options for easier installation/flexibility

Disadvantages of China Standard rubber bellows mechanical seal WM202

● Limitation on barrier fluid pressure capability

● Does not handle reverse pressure (unless double-balanced)

● Product dilution
