• Balanced for Pressure: The design is hydraulically balanced to operate reliably at pressures up to 25 bar, common in high-rise building booster systems.
• Positive Drive Pins: Heavy-duty drive pins ensure positive torque transmission, preventing the seal from slipping on the shaft during high-load starts.
Key Features
• High-Pressure Solution: A robust wave spring seal replacement for large Grundfos TP, NB, and NK series pumps.
• Compact & Strong: The wave spring design provides high closing force in a short axial space, while the Tungsten Carbide faces handle high pressure and abrasive particles.
• Non-Clogging: The open wave spring architecture is less susceptible to clogging by scale or debris than traditional coil springs.

Workshop
This workshop is equipped with professional processing equipment and integrated with standardized material warehousing management, enabling a one-stop production process from precision machining to finished product delivery. It ensures part machining accuracy and production efficiency, meeting various high-specification manufacturing requirements.
Product Research, Development and Testing
Our Product R&D and Testing focuses on optimizing seal performance through advanced simulation and material analysis. All seals undergo rigorous trials, including thermal cycling and pressure tests, to ensure durability, minimal leakage, and long service life in demanding industrial environments.
Industry Solutions
Case Study
District Cooling: Large inline pumps in a district cooling plant faced seal failures due to rust particles in the water. We upgraded them to TC/TC Wave Spring Seals. The hard faces crushed the particles without damage, restoring system reliability.
Testimonials
A heavy-duty upgrade for the standard BAQE seal. The TC faces last significantly longer in our older heating loops.

FAQs about Metal Bellows Seals for High Temperature Pumps
Q: Is this compatible with the Grundfos BAQE code?
A: The standard BAQE code uses Carbon/SiC. This seal is an upgrade equivalent to "BAQE" but with Tungsten Carbide faces (often coded as GQQE or similar depending on naming convention), offering better durability in dirty water or systems with pipe scale.
Our company is specialized in the production of sealing materials, mechanical seals , cartridge seals.
