The Grundfos Cartridge Mechanical Seal in Germiston is a dedicated pre-assembled shaft sealing unit, specially designed for Grundfos rotary pumps and multistage pumping systems. The cartridge seals are produced with a specific size and geometry to fit the Grundfos pump chambers with great accuracy.
The Full Cartridge Unit Contains the Following:
The factory preset design reduces the difficulty of alignment and installation and makes the installation faster, safer and reliable.
The concept behind these kinds of seals is that the rotating and stationary sealing faces need to have controlled contact, while a very thin layer of lubricant between them reduces friction and heat production when they are in motion.
Grundfos cartridge mechanical seals are amongst the most popular seals on the market due to the following reasons:
For continuous service, diverse designs of sealing faces, such as balanced, minimise hydraulic load and operational wear, further enhancing sealing efficiency.

Grundfos Cartridge Mechanical Seal Material Coding System
The Grundfos cartridge mechanical seals are numbered according to a special code, which identifies seal design, face materials and elastomer combination.
Common Material Codes
Example Seal Code
The Grundfos Cartridge Mechanical Seal is used in a wide variety of applications, including:
Precision-engineered Grundfos cartridge mechanical seals are applicable in industrial and commercial pumping systems where reliable sealing is essential.
Major Industrial Applications
The operating principles of Grundfos cartridge mechanical seals are discussed below:
A Grundfos cartridge mechanical seal works by creating a stable sealing interface between the rotating pump shaft and stationary pump housing.
While the seal face rotates with the seal shaft, the stationary seal face stays in place inside the gland assembly. The two sealing faces are precision lapped for a thin lubrication film to reduce friction and leakage.
Operating springs in the cartridge assembly ensure a proper sealing face-to-face contact during operation.
The balanced cartridge seal design aids in:
The built-in sleeve also helps prevent corrosion, scoring and erosion of the shaft.
The Grundfos Cartridge Mechanical Seal is comprised of the following parts.
A Grundfos cartridge mechanical seal has many precision-made parts to ensure it seals effectively.

Technical guidance before & after purchase
The right material pairing directly determines how long a seal lasts and whether it handles your process fluid without failure. Below are the materials available for this seal type — we select or recommend based on your application.
Self-lubricating with good chemical resistance. The standard rotating face material for general-duty and water pump applications.
Exceptional hardness, wear resistance, and chemical compatibility. The preferred mating face material for demanding applications.
Maximum resistance to shock loads, vibration, and abrasive slurries. Used where SiC may chip or fracture under impact.
Springs, glands, sleeves, and retainer components. Corrosion-resistant structural integrity across all seal types.
Standard O-ring material for oils, fuels, and general water service. Temperature range: -40°C to +120°C.
Excellent resistance to hot water, steam, and dilute acids. Used where NBR would swell or degrade.
High-temperature O-ring for chemical, petroleum, and aggressive fluid applications. Range: -20°C to +200°C.
Replaces elastomeric secondary seals entirely. Ideal for extreme temperatures (cryogenic to +450°C) where no elastomer survives.
Material selection depends on your process fluid, temperature, pressure, and shaft speed. Contact our team for a recommendation specific to your application.
