• Non-Clogging Spring: The wave spring's open structure is less prone to clogging with lime or scale compared to coil springs.
• Torque Drive: Features robust drive pins to transmit torque from the shaft to the seal face, preventing slippage under high loads.
Key Features
• Grundfos Replacement: A robust replacement for Grundfos pumps using wave spring seals (e.g., TP, NB, NK series).
• Heavy-Duty Faces: Solid Tungsten Carbide faces are standard, designed to handle the high pressure and vibration of large vertical inline pumps.
• Compact Wave Spring: The wave spring design reduces the axial length, allowing for a compact seal chamber while providing high closing force.

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 Heating: Large Grundfos TP pumps in a heating plant were leaking due to scale buildup on the seal faces. We installed TC/TC Wave Spring Seals. The hard faces crushed the scale, and the wave spring resisted clogging, ensuring reliable winter operation.
Testimonials
A heavy-duty alternative to the standard BAQE seal. The TC faces last forever in our heating loops.
