Mechanical Seal with Magnetic Coupling -- CHEM MAGNET The CHEM Magnet is in principle constructed in the same way as the CHEM but with a synchronous magnetic coupling forming the shaft seal. This operates slip-free, i.e. the pump...
Double Mechanical Seal, Buffered -- DD The double mechanical seal with buffered fluid (DD) is suitable for a max. viscosity of 1.000 Pas, because the internal parts of the mechanical seal do not get in contact...
Mechanical Seal -- ED The single mechanical seal (ED) is the standard seal for WITTE CHEM pumps. It is suitable for max. viscosity of 10 to 50 Pas. Min. suction pressure: 1 bar (15...
Stuffing box The stuffing box is a simple seal for WITTE gear pumps. The operative range is similar to the viscoseal. It is suitable from low to high viscosities. The standard material...
Vacuum Viscoseal with Stuffing Box The vacuum viscoseal with buffered stuffing box is the standard seal for WITTE POLY pumps. It is a combination of a dynamic (viscoseal) and a static (stuffing box) sealing system.
