Replacement Seal

​The AESSEAL CS Replacement Cartridge Mechanical Seal is a high-performance sealing solution designed for various industrial applications, particularly in pumps handling clean water, wastewater, and light chemical media. This seal is engineered to provide reliable sealing performance, ease of installation, and extended service life

The AESSEAL CS Replacement Cartridge Mechanical Seal is a single, unbalanced mechanical seal featuring a conical spring that rotates with the shaft, making it dependent on the direction of rotation. Torque transmission is achieved through this conical spring mechanism. The seal is particularly suited for applications involving clean water, wastewater, and light chemical media.

The BT-FN is a single, unbalanced mechanical seal designed for plain shafts. It features a conical spring that rotates with the shaft, making it dependent on the direction of rotation. Torque transmission is achieved through this conical spring mechanism. The seal is particularly suited for applications involving clean water, wastewater, and light chemical media

• Single seal configuration

• Unbalanced design

• Conical spring rotating with the shaft

• Direction-dependent operation

• Torque transmission via conical spring​

The G13 is the stationary seat (stator) portion of Burgmann’s elastomer bellows mechanical seal arrangement, commonly paired with MG1, MG12, or MG13 rotating bellows assemblies. It’s offered as a standalone replacement part compatible with various seal lines including Qseals ST13, Vulcan 8B and Eriks SFO

Primary Uses: Employed in water treatment, slurry and wastewater pumps, chemical and petroleum processes, industrial rotary equipment 

• Performance Benefits:

  • Compact design with simple fitment

  • Tolerant of shaft misalignment and runout

  • Flexible axial compensation via bellows

  • Suitable for most abrasive, corrosive, or fluid-handling contexts.

• G4 typically refers to a stationary seat (stator) used in mechanical seal systems .

• It forms part of a cartridge or component seal, usually paired with a rotary face (e.g., Bellows seals like MG1S‑G4 or conical spring seals like M32‑G4/M377‑G4).
  
  The Burgmann G4 system is a versatile, industrial-grade sealing platform. Whether you need just the stationary G4 seat or a full MG1/M32/M377 cartridge assembly, you can customize materials, elastomers, and design to match your application—from cryogenic to 200 °C, moderately pressurized environments, and up to 20 m/s shaft speeds. Available globally through numerous suppliers, it's ideal for a wide range of sectors, including chemical processing, food & beverage, sewage, sugar, and more.

• Common across industries: pumps in chemical, food & beverage, sewage, sugar, paper, and general process applications.
  
  
  

The Burgmann G60 is a stationary (seat) stator—the stationary component of a mechanical seal assembly. It's commonly paired with rubber-bellows rotary seals like Burgmann MG series (e.g., MG1, MG13). These stators are precision-seated to form a sealing interface with the rotating faces of the mating ring

• The G60 is just the stationary stator of a mechanical seal (free faces: Ceramic, SiC, or TC).

• It pairs with a rotary MG1 seal (bellows-type) rated for ≤1.2 MPa, –20 °C to +120 °C, up to 10 m/s
  
  

The Burgmann M7N (M07) mechanical seal, often referred to as the "wave-spring seal," is a robust, unbalanced, single mechanical seal designed for a wide range of rotary equipment applications. 

Introduced by Burgmann, the M7N (also called M07 in some catalogs) is engineered to meet DIN 24960 and ISO 3069 standards.This bi-directional, unbalanced seal is equipped with a non-welded continuous wave spring (or super-sinus/coil spring), providing uniform face loading and allowing for axial movement of the rotary ring

The HE Burgmann M37/M37G Replacement Seal is a high-performance, elastomer bellows mechanical seal designed to meet the sealing demands of a wide variety of rotating equipment. It serves as a direct interchangeable replacement for the original Burgmann M37 and M37G models, maintaining the same level of reliability, durability, and compatibility across various pump types and process conditions.

This seal features a single-spring, elastomer bellows design, which provides self-adjusting axial movement to accommodate shaft misalignment, vibration, and wear. The elastomer bellows also eliminates the need for dynamic O-rings, reducing the potential for secondary sealing issues. The M37 model is a single-directional seal, designed for clockwise shaft rotation, while the M37G variant is balanced, enabling it to operate effectively in higher-pressure systems.

The mechanical seal includes:

• Rotary face: Typically made from high-grade Carbon, Silicon Carbide, or Tungsten Carbide

• Stationary seat: Options include Ceramic, Silicon Carbide, or Tungsten Carbide

• Secondary seal: Constructed from robust elastomers such as Nitrile (NBR), Viton (FKM), EPDM, or Kalrez, depending on chemical compatibility

• Metal components: Stainless steel (SS304/SS316) for spring and retainer, ensuring corrosion resistance and mechanical strength
