• Face Retention: The TC face is securely shrink-fitted or pin-driven to prevent spinning out under high-torque start-up conditions common in viscous fluid pumping.
• Corrosion Resistant Binder: Uses a Nickel-binder Tungsten Carbide grade to ensure corrosion resistance against acidic cleaning agents (CIP).
Key Features
• Heavy-Duty Upgrade: Replaces standard Carbon/Ceramic seals in APV W+ and Puma series pumps with solid Tungsten Carbide (TC) faces.
• Impact Resistant: TC faces are extremely tough and resist cracking from pressure shocks or solids in the fluid, unlike brittle ceramics.
• Hygienic Design: Meets sanitary standards with smooth, cleanable surfaces suitable for food and beverage lines.

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
Sugar Syrup Pump: An APV W+ pump moving viscous sugar syrup was destroying carbon seals. We installed this Tungsten Carbide replacement. The hard faces resisted the abrasive sugar crystals, extending seal life from 2 months to over 2 years.
Testimonials
We upgraded all our APV syrup pumps to these TC seals. No more cracked faces during startup.

FAQs about Metal Bellows Seals for High Temperature Pumps
Q: Does this fit the W+ series?
A: Yes, it is a direct replacement for the standard single seal in APV W+ series pumps. We need to know the shaft size (e.g., 25mm, 35mm) to supply the correct kit.
Our company is specialized in the production of sealing materials, mechanical seals , cartridge seals.
