• Nickel Binder TC: We use Nickel-bonded Tungsten Carbide for superior corrosion resistance in water and mild chemicals compared to Cobalt-bonded grades.
• Complete Solution: Kit includes rotary, stationary, O-rings, and spring, ensuring all wear parts are replaced at once.
Key Features
• Heavy-Duty Kit: A comprehensive seal kit featuring Tungsten Carbide (TC) faces, designed for abrasive and high-shock applications.
• Impact Resistant: TC faces are far tougher than ceramic or SiC, making them immune to cracking from hydraulic shock or solid impacts.
• Universal Fit: Kits available to fit standard Type 1, Type 21, and metric pump dimensions.

Industry Solutions
Case Study
Sand Slurry Pump: A quarry water pump was destroying ceramic seals in days. We supplied a TC/TC Elastomer Seal Kit. The Tungsten Carbide faces ground the sand to dust without leaking, extending pump life to 6 months.
Testimonials
We upgrade all our rental dewatering pumps with these TC kits. They take the abuse that ceramic seals can't.

FAQs about Metal Bellows Seals for High Temperature Pumps
Q: Is TC better than SiC?
A: For impact and shock, yes. TC is not as hard as SiC but is much tougher (less brittle). It is the best choice for pumps that might cavitate or pump rocks.
Our company is specialized in the production of sealing materials, mechanical seals , cartridge seals.
