Mechanical seals
At Sizonke Trading, we understand the critical role reliable mechanical seals play in keeping your equipment running smoothly. That's why we offer a wide range of field-tested, high-quality mechanical seals sourced from the world's leading manufacturers.
Our selection process is rigorous. We choose seals designed for various applications, ensuring you find the perfect fit for your needs. Whether you require heavy-duty seals for demanding industrial environments or precision seals for sensitive applications, we have you covered.
-
Split Cartridge seals: for equipment maintenance. Unlike traditional mechanical seals, which require partial disassembly of the machinery for replacement, split cartridge seals offer a faster, easier, and more cost-effective solution.
-
Cartridge Seals: Pre-assembled units containing all the sealing components. Easy to install and replace, reducing downtime. Often used in applications requiring clean environments or ease of maintenance.
-
Balanced Seals: Ideal for high-pressure applications. The pressure on the seal faces is balanced, reducing wear on the secondary seal (often a bellow) and shaft.
-
Unbalanced Seals: More cost-effective option for low-pressure applications. The spring pushes the seal faces together, creating the sealing force.
-
Bellows Seals: Utilize a flexible metallic or non-metallic bellow to create a spring effect and maintain sealing force. Suited for applications with misalignment, varying pressures, or contaminants
-
Diaphragm Seals: Employ a flexible elastomeric diaphragm to create the sealing force. Good for clean liquids and moderate pressures.
