How the L three screw pump fits into the KRAL product range.
KRAL L series three screw pumps extend the pressure range from the 16 bar limit of the K three screw pump to 63 bar. This places the medium-pressure L series three screw pump between the K and C series.

In standard applications, the L series three screw pump can be a costeffective alternative to the CG series.

The L three screw pump takes highpressure marine applications a step further. Its casing is made from ductile iron and is therefore approved for use on board ships. The L three screw pump also has a sealed, lifetime-lubricated, external bearing, which is not exposed to the pumped medium and is maintenance-free.

Easy servicing.
The main spindle of the L three screw pump can be disassambled together with the seal casing, as all the rotating parts are pre-assembled in the removabled end cover. This makes the L series three screw pump particularly easy to assemble, dismantle and maintain.

The L series three screw pump gets its name from its long construction. The long spindles allow a discharge pressure of up to 63 bar.

KRAL L three screw pumps 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.
