metal slurry pump wire

No Page Title

Component mechanical seal 4K

For the KWP pump type series. Single, balanced component seal, stationary design. The seal can optionally also be operated with unpressurised quench liquid.

Main Applications

Waste water containing stringy material and abrasive particles

Technical Data

Cartridge seal No

Design Stationary

Balancing Balanced mechanical seal

Sealing type Single

Maximum allowable fluid temperature 150 °C

Benefits

The seal is tailored to the seal installation space of the pump and therefore perfectly suitable for fluids with a high solids content.

Stationary design; multiple springs located outside the fluid handled The large springs are insensitive to contamination and provide uniform surface pressure across the seal faces, thus ensuring a long service life.

Can optionally also be operated with unpressurised buffer fluid
