Semi-Cartridge Front-Loading Seal


Semi-Cartridge Seal

Seal-Locking Key

The FDS’ mechanical seals are fully immersed in the flowing medium. Their smart layout ensures improved protection from leakages with both single- and double-acting seals. The semi-cartridge principle, in combination with the clever design of the pump casing in three segments, make mounting and replacing seals simpler than ever. If needed, they can be removed and loaded through the front with just a few quick and easy steps.



The FDS’ pump casing, cover and the two screws can be removed in just a few simple steps.

After unlocking the item keys that secure the mechanical seals in place, they can be removed and replaced easily and quickly from the front of the pump.

The entire procedure requires only a few moments and can be carried out without great technical effort.

Gearbox Access

When designing the gearbox, we put a special emphasis on creating a smart yet hands-on layout. Access to the synchromesh gear is facilitated through a cover that can be removed easily with just a few turns of a  screw. The pump can be kept in its position, and even moving the drive becomes unnecessary.

Thanks to its specially designed bearings, the FDS offers previously unimagined simplicity with regard to all gear-related maintenance procedures.
