Why Pulim Springs

Pulim springs are designed specifically for spring-energized sealing systems rather than general industrial spring applications.

Broad Design Selection

Available spring configurations include:

  • Helical
  • V-Spring
  • U-Spring
  • Independent-Support
  • Full-Contact
  • Slant Coil

Multiple Material Options

Wide range of stainless steel and specialty alloy materials available to match application requirements.

Integrated Sealing Expertise

Unlike standalone spring suppliers, Pulim combines:

  • Seal engineering
  • Material development
  • Spring manufacturing
  • CNC machining capability

This allows us to optimize both the spring and seal as a complete sealing system.

Custom Manufacturing

Support for:

  • Custom dimensions
  • Material selection
  • Application-specific spring force requirements
  • Prototype and production quantities
