Product catalog summary

Wave Spring Seals Overview

Characteristics:
Wave spring seals are available in both balanced and unbalanced designs. They are attached to the shaft using Allen screws and are not dependent on the rotation direction. These seals are designed to handle sticky fluids and fluids with particles and fibers without getting blocked, thanks to their open leaf design which provides a self-cleaning effect.

Operating Limits:
The seals operate within specific limits defined by the PV factor, which considers the sealing system characteristics and application conditions. The temperature resistance is contingent on the material of the secondary seals used. The operating limits vary across different models, with pressure limits ranging from 10 to 35 kg/cm², velocity up to 20 m/s, and temperature ranges from -50°C to +220°C.

Description:
Wave spring seals are recommended for applications involving high pressures and sticky or particle-laden fluids. They are compliant with standard EN 12756 and are available with optional features like a pumping ring to reduce temperature between contact surfaces and facilitate barrier fluid movement in double mounting scenarios.

Components:
The main components of wave spring seals include rotating and stationary contact surfaces, O-rings, springs, metal frames, set screws, and rings. Some models also include elastomeric cups and coupling pins.

Dimensions:
The document provides detailed dimension charts for various models, specifying shaft sizes, rotary and stationary part dimensions, and total lengths. These dimensions are subject to changes or modifications.

Applications:
Wave spring seals are suitable for use in small spaces and are ideal for lobe pumps due to their compact size. They are designed for both internal and external mounting and are robust due to the use of stainless steel in the rotating parts.

Conclusion:
Wave spring seals offer a versatile and reliable sealing solution for a variety of industrial applications, particularly where high pressure and challenging fluid conditions are present. Their design ensures durability and efficiency, making them a preferred choice in many sectors.
