XFLO P U M P S XS SERIES Single Stage Double Suction Split Casing Centrifugal Pump
General and Construction 1. Applications Waterworks, Irrigation, Drainage pumping stations, Power stations, Industrial water supply systems & fire fighting applications in refineries. 6. Bearings Both sides are grease lubricated deep groove ball bearings, sealed for life. Oil lubrication are also available as optional. 2. Operating data Pump sizes DN 80 to 900mm Capacities Q up to 00I/s Total heads H up to m Operating pressure P up to bar Operating temperature t up to +5 C 7. Shaft seal Uncooled soft - packed stuffing box or uncooled single acting. Unbalanced mechanical seal. According to DIN 24960, independent of direction of rotation. For operating pressure 16 bar balanced mechanical seal is used. 3. Model code XS 125 290 V Series Suction(mm) Discharge(mm) Nominal Impeller diameter(mm) Vertical type 8. Materials Volute casing Cast iron Ductile cast iron Cast steel DIN GG 25 GGG GS C25 4. Pump Casing The casing is axially split, which permits removal of the complete rotor without disturbing either piping or the motor. Pumps generating high heads have double volutes to reduce radial forces, ensuring minimal shaft deflection and low bearing loads. Replaceable wear rings protect the casing at the impeller running clearances. High head pumps are also fitted with replaceable impeller wear rings. Flanges drilled to ISO, DIN, BS or ANSI. Impeller Cast iron GG 25 Bronze G CuSnZn Stainless steel 1.4581 or 1.28 Shaft C steel C45N Cr steel 1.21 Casing wear rings Cast iron GG 25 Bronze G CuSn5ZnPb Brass G CuZn15Si4 5. Impeller The closed impellers have double curved vanes. The double suction design gives practically zero axial forces. Each impeller is statically and dynamically balanced according to ISO 19. Note: 4 or 316 stainless steel pump are also available.
Advantages 1. Your technical advantage Innovative casing in-line design short distance between bearings and correspondingly short shaft leak-tight due to compact joint flange with long, prestressed bolts counter-rotation possible with similar parts double volute version for appropriate total heads easy mounting-self-aligning upper casing High-performance impeller minimal axial thrust due to double-entry impeller optional impeller wear rings new vane passage with excellent hydraulic characteristics 2. Your service advantage Service friendly shaft completely sealed and dry for zero corrosion short and rigid with negligible vibrations replaceable shaft protecting sleeves no threads exposed to pumped medium, long operating life and no corrosion adjustment-free assembly quick and easy assembly/dismantling of the rotor components due to elastically prestressed mountings Excellent efficiencies 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 no drop in efficiency due to cost effective replaceable casing wear rings and impeller wear rings smooth, low loss running due to a swirl-free inlet Long-life bearing covered, sealed for life grease lubricated antifriction bearings for a long service life open gland, i.e. enough space for service activities optional: oil lubrication with constant level oiler Application-orientated seals asbestos-free, potable water quality soft-packed stuffing boxes optional: mechanical seals 1
