GL-Provent S.L. supplies a range of spring cartridge seals, including single and double mechanical seals to suit the most demanding applications.



Cartridge seals consist of a modular design, balanced, multiple spring, O-ring mounted seal, with various bolt holes and flush port combinations. Their construction eliminates the need to measure and set spring compression, and having a mechanical seal pre-assembled means that the seal faces are protected from damage during installation.
Fitting errors are significantly minimised by the Self-Aligning Stationary Faces and minimal internal/external Gland protrusion. Mechanical Seal lifetime is highly improved and maintenance frequency is greatly reduced. All three types listed eliminate shaft fretting and also guard against the clogging of seal faces and springs.
Key Benefits:
- Easy Installation
- Self-Aligning Stationary Faces
- Hydraulically Balanced Faces
- No Clogging or Seal Faces/ Springs
- No Shaft Fretting
- Multiple Spring
- O-ring Mounted
Typical Applications
Cartridge Seals are cost-effective and ideal replacements for Mechanical Seals commonly found in a wide range of industries, particularly in public utility, industrial and marine applications, but also many more.
