Mechanical seal R-FR
Mechanical seals R-FR - with a central conical spring, for use in Fristam pumps. Usually, Fristam® sanitary pumps use either single mechanical seals or two seals in a pair: one on the product side (L, internal), the other on the drive side (R, external, without support). Fixed friction pairs with an o-ring, as well as with rotation protection.
All materials in contact with the environment are FDA certified.
Application: Fristam pumps FP, FPE, FPX, FPR, FPH, FPHP, FZX, FS, FSI, FSH.
