• With inherent hydraulic balance of axial thrust
• Exceptional efficiency over a wide range of flows
• Excellent Net Positive Suction Head Required (NPSHR) also in flow run out conditions

• Radial load balancing
• Innovative cut-water design for minimum radial load
• Self-draining
• Compact dimensions for reduced bearing span

360º fixation for enhanced stiffness

Standard SMD

• Greased for life, deep groove single ball bearings at both drive and non-drive ends

Configured SMD

• Heavy duty bearing design
• Generously sized for life cycle higher than 100,000 hours, grease or oil lubricated bearings available
• With angular contact, double ball bearing at drive end and single radial ball bearing at the non-drive end
• For higher power requirements, typically in large water transport applications

• Full dry-shaft design
• Single, balanced mechanical seal as standard shaft sealing
• Dowel pins for alignment of the casing halves
• Precision register fits, adjustment of rotor assembly in the casing is not needed
• Bearings, bearing nuts, bearing isolators, mechanical seal, shaft seal sleeves are replaceable without removing the upper casing

Standard SMD:

• Single mechanical seal

Configured SMD

• Single mechanical seal
• Gland packing available as an option
• Other mechanical seal configurations available upon request

• With grease lubricated thrust bearing at the drive end and product lubricated proven design bearing at the non-drive end
• Interchangeable casing with the horizontal arrangement

• Cooling fan in thrust bearing for heavy duty applications such as high speed, high ambient temperature, provides effective cooling without need of cooling water
• Connection for temperature and vibration monitoring instruments

• Shrink fit and axially secured
• Offers additional impeller protection
• Reduced maintenance cost in heavy duty applications

• Plan 11 as standard:

Seal flush from pump discharge through orifice. Default single seal flush plan.

• Plan 31 as optional:

Seal flush from pump discharge through cyclone separator. Centrifuged solids are returned to pump suction

• Plan 32 as optional:

Seal flush from an external clean source
