Your technical advantages Your service advantages
Innovative casing High-performance impeller Service-friendlyshaft
- in-line design - minimal axial thrust due to - completely sealed and dry for
- short distance between bearings and double-entry impeller zero corrosion
correspondingly short shaft - impeller wear rings optional - short and rigid with negligible vibrations
- leak-tight due to compact joint flange - new vane passage with - replaceable shaft protecting sleeves
with long, prestressed bolts excellent hydraulic - no threads exposed to pumped medium, i.e.
- counter-rotation possible with the characteristics long operating life and no corrosion
same parts - adjustment-free assembly
- double-volute version for appropiate - quick and easy assembly/dismantling of
total heads the rotor components due to elastically
- upper casing self-aligning and, therefore, prestressed mountings
easy to mount
Subject to change without notice.
Long-life bearings
- covered, sealed for life, grease-
lubricated antifriction bearings for a
long service life
Excellent efficiencies - open gland, i.e. enough space for

service activities
Outstanding NPSH
- computer-optimized double-entry impellers
- smooth surfaces inside the casing and on the impeller
- smooth, quiet running also guaranteed by a large
impeller eye area Application-orientated seals
- asbestos-free, potable-water quality
1384.1/5-10
- no drop in efficiency due to cost-effective, replaceable
casing wear rings and impeller wear rings soft-packed stuffing boxes
- smooth, low wear running due to a swirl-free low-energy loss - or bi-directional mechanical seals
