XS Double Suction Centrifugal Pump

XS type pump is a new generation of high performance single-stage double-suction centrifugal split pumps. They are mainly used in delivering liquids of the water plant, air conditioner circulation water, heating pipe network system, building water supply, irrigation and drainage of pump stations, power plants, industrial water supply system, fire protection, ships industry and mine. 

• Capacity  Q :               50~20000m3/h
• Head  H :                     10~230m
• Suction dia: DN :         100 -1400mm
• Discharge dia:  DN :     80-1200mm
• Temperature  T :          -15℃~200℃

 1.Shaft

a. Heavy duty shaft completely sealed and dry for zero corrosion

b. Short and rigid with negligible vibrations

c. Replaceable shaft protecting sleeves

d. No threads exposed to pumped medium, long operating life and no corrosion

e. Adjustment-free assembly

f. Quick and easy assembly/dismantling of the rotor components due to elastically prestressed mountings

2. Bearing

a. SKF covered, sealed for life grease lubricated antifriction bearings for long service life

b. Open gland, enough space for service activities

c. Optional: oil lubrication with constant level oiler

3.Seal

a. Asbestos-free, potable water quality soft-packed stuffing boxes

b. Unbalanced mechanical seal, according to DIN24960 Balance mechanical seal for operating pressure >16 bar on required

c. Cartridge-type mechanical seal on required

4.Impeller

a.  Computer-optimized minimal axial thrust double entry impellers

b. Impeller is statically and dynamically balanced according to 1S01940

c.  Optional impeller wear rings

d.  New vane passage with excellent hydraulic characteristics high-performance improved by CFD

5.Casing

a.  In-line axially split design which permits removal of the complete rotor without moving the pipe and motor

b.  Short distance between bearings

c. Leak-tight due to compact joint flange with long, prestressed bolts

d.  Counter-rotation possible with similar parts

e. Double volute casing reduces radial forces on the impeller and consequently the bearing loads

f. Easy mounting self-aligning upper casing

g.  Flange drilled to ISO, DIN, BS or ANSI

h. Smooth surface inside and epoxy coating as required

I. Replaceable wea『 rings protect the casing at the impeller running clearances

j. Excellent efficiencies and outstanding NPSH improved by CFD

k. Heavy duty casing design for high working pressure
