• Hydraulic Balance: The cartridge design incorporates a balanced face geometry, allowing it to handle pressure spikes in centrifugal systems without face separation.
• Easy Installation: Eliminates the need for measuring spring compression, reducing installation time by 75% compared to component seals.
Key Features
• Heavy-Duty Cartridge: A pre-assembled cartridge seal designed specifically for centrifugal pumps handling dirty water, slurries, or abrasive fluids.
• Solid TC Faces: Features solid Tungsten Carbide faces on both rotary and stationary sides to resist grooving from abrasive particles.
• Clog-Resistant Design: The spring mechanism is located outside the process fluid (or protected by the cartridge sleeve) to prevent fouling from sludge.

Case Study
Mining Dewatering: Centrifugal pumps removing mine water were failing due to sand intake. We upgraded them to this TC Cartridge Seal. The installation was fast, and the TC faces handled the grit effortlessly, reducing maintenance intervals significantly.
Testimonials
We retrofitted our entire line of process water pumps with these TC cartridges. The reliability has improved drastically compared to the old packing glands.

FAQs about Metal Bellows Seals for High Temperature Pumps
Q: Can this replace a standard ANSI pump seal?
A: Yes, we have models designed to fit standard ANSI and ISO pump stuffing boxes (e.g., Goulds, Durco, KSB) directly. The cartridge gland plate is designed with universal slots to accommodate various bolt circles found on these standard pumps.

Our company is specialized in the production of sealing materials, mechanical seals , cartridge seals.
