Shaft seals

Single mechanical seal (ED)
The single mechanical seal (ED) is the standard seal for WITTE CHEM pumps.

Vacuum mechanical seal (AD), buffered
The single mechanical seal with buffered fluid (AD) in specially designed for vacuum conditions on the suction side

Double mechanical seal (DD), buffered
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 with the pumped fluid.

Viscoseal
The viscoseal is a dynamic seal that can be heated or cooled. It is the standard seal for WITTE EXTRU pumps.

Vakuum viscoseal with stuffing box
The vakuum viscoseal with buffered stuffing box is the standard seal for WITTE POLY pumps.

Stuffing box
The stuffing box is a simple seal for WITTE gearpumps
