Wave Spring Seals

Wave Spring Seals

Wave spring seals are mechanical seals designed with a single wave spring or sinusoidal wave spring that provides controlled face loading in compact pump and rotating equipment applications where space efficiency and reliable sealing performance are important.

This seal design supports stable contact between the rotating face and stationary seat while helping maintain dependable leakage control in compact process and pump duties. Wave spring seals are commonly selected where smaller envelope requirements, compact working length and even face loading are important in replacement and equivalent seal applications.

Wave spring seals are commonly used in:

• pumps
• process pumps
• compact rotating equipment
• food and beverage equipment
• sewage treatment equipment
• systems handling water, light chemicals and selected viscous media

Depending on design, they may include:

• single wave spring seals
• sinusoidal wave spring seals
• pusher wave spring seals
• non-pusher wave spring seals
• O-ring mounted wave spring seals

These seals are typically selected where buyers need:

• compact seal arrangement
• even face loading
• stable sealing performance
• dependable leakage control
• reliable service life in continuous-duty pump applications

To specify the correct wave spring seal, provide:

• shaft size
• seal chamber or housing dimensions
• equipment type
• fluid handled
• operating pressure and temperature
• speed and duty conditions
• existing seal sample or drawing if replacing

Kaybin supports replacement wave spring mechanical seals, equivalent seal matching and seal selection for pumps and rotating equipment across South Africa and Africa.
