The main spindle of the L series can be disassambled together with the seal casing, as all the rotating parts are pre-assembled in the removable end cover. This makes the screw pump particularly easy to assemble, dismantle and maintain.
KRAL L series use lifetime-lubricated, external ball bearings. FKM sealing discs with high temperature stability prevent wash out. This increases the life of the bearing and reduces maintenance costs.
The innovative one-piece casing design guarantees that pressure-side leakages are a thing of the past.
