PTFE Metal Wave Spring Seal for Centrifugal Pump Replacement
• Wave Spring Technology: Provides uniform face loading with a fraction of the space of coil springs, preventing face distortion.
• Replaceable Faces: wave spring seals are designed with snap-in faces for easy refurbishment and material upgrades (e.g., swapping Carbon for GFT).
Key Features
• Compact Axial Length: Utilizes a wave spring instead of a coil spring, significantly reducing the axial space required, perfect for compact centrifugal pumps.
• Superior Chemical Resistance: Uses a PTFE wedge for secondary sealing, providing near-universal chemical resistance where rubber elastomers fail.
• External Mounting: Wave spring seals are typically designed as an externally mounted seal, keeping metal parts out of the corrosive medium.

Industry Solutions
Case Study
Acid Transfer Pump: A sulfuric acid transfer pump had very limited stuffing box space. Standard springs wouldn't fit. We installed this Wave Spring PTFE seal. The compact design fit perfectly, and the PTFE wedge resisted the acid attack for 12 months maintenance-free.
Testimonials
The only wave spring seals that fits our older, compact chemical pumps. The wave spring design is a lifesaver for space-constrained installations.

FAQs about wave spring seals for High Temperature Pumps
Q: Why use a wave spring seals?
A: A wave spring exerts the same force as a coil spring but occupies 50% less compressed height. This is crucial for retrofitting modern seals into older pumps with short stuffing boxes.
Our company is specialized in the production of sealing materials, mechanical seals , cartridge seals.
