• Protected Spring: The wave spring is often shielded or located outside the fluid path, preventing it from fouling with product.
• Torque Drive: Uses robust drive pins to transmit torque, ensuring the seal face rotates positively even in thick fluids.
Key Features
• Wave Spring Design: A compact, robust seal featuring a wave spring. This design is resistant to clogging and fits into shorter axial spaces than coil spring seals.
• Viscosity Handling: Ideal for pumps handling high-viscosity fluids like sugar syrup, oil, or paint, where coil springs might torque out.
• Balanced: Hydraulically balanced to handle pressure spikes common in vertical turbine and booster pump applications.

Industry Solutions
Case Study
Paint Circulation: A paint line used gear pumps with HJ92N seals. Standard seals clogged with dried paint. We supplied HJ92N replacements with wave springs. The wave spring didn't clog, and the seal reliability improved by 200%.
Testimonials
The HJ92N is a tank. We use it on all our viscous product pumps. The wave spring design is far superior to single coil springs.

FAQs about Metal Bellows Seals for High Temperature Pumps
Q: What makes the wave spring better?
A: A wave spring provides high closing force in a small space and has no coils to clog with viscous product. It applies pressure evenly around the seal face.
Our company is specialized in the production of sealing materials, mechanical seals , cartridge seals.
