The Flexaseal Style 78A tandem cartridge seal is specifically designed for ruggedness and durability to withstand higher temperature or dirty services were leakage and emissions must be completely contained. Design elements include retained faces to allow for pressurized or unpressurized barrier systems, rotating metal bellows for self-cleaning and pilot gland to positively center the seal.

Style 78A is available in a High Temperature (HT) design with static O-Rings or with Grafoil Packing. This allows for operating temperatures up to 800F, while improving reliability by eliminating the dynamic secondary sealing element.

Bellows Mechanical Seal are a type of mechanical seal where the spring element is a bellows. This eliminates the need for a secondary dynamic seal e.g o-rings. Bellows Mechanical Seals are also known as non-pusher seals as they have a static secondary seal which stays in place against the shaft, sleeve or on the gland of the pump.

A bellows mechanical seal is used where a dynamic seal is deemed unsuitable for the application e.g high temperature medium slurry or high seal hysteresis.

The primary mechanical seal functions exactly the same as a standard mechanical seal except the spring element is now being replaced with a bellows. The friction from the dynamic seal (e.g o-ring) is not a consideration.

However if a bellows mechanical seal should fail it can be due to several reasons such as; poor wielding, product particulate getting into the bellows and causing the spring element to fail, chemical and/or abrasive attack or over-pressure.

If you have any query around how to install bellow mechanical seals for pumps or have some concerns around the seal failures, why not contact one of our seal specialists below to discuss it in more detail and find out how we can help solve your issues and get your process back up and running reliably again.

A Bellows seal does not have a secondary seal that must move along the shaft or sleeve to maintain seal face contact. The secondary seal is static state at all times, even when the pump is in operation.

Primary seal face wear is typically accommodated by welded metal or elastomeric bellows which move to assist in the compression of the rotary to stationary seal faces.

Bellows seals allow for high and low temperature applications when used in conjunction with metal bellows. They do not require a rotating secondary seal, which means it is not prone to secondary seal hang-up or fretting along the shaft or sleeve.
