Clean water pump SMD for potable and treated water

Clean water pump with drinking water certificates

The SMD water pumps are available as standard and configured pumps to meet the demands of different water applications. With a best-in-class hydraulic design, the SMD pumps can take on challenges in raw, clean, sea and brackish water applications. The clean water pumps have ACS and NSF 61 drinking water certifications.

Main benefits
  • A wide range of configurations including standard pumps to meet any specific application need
  • Optimum hydraulic fit with high efficiency maintained over a wider flow range
  • Exceptionally low Net Positive Suction Head Required (NPSHR) value not only at the best efficiency point but also on overload
  • Maintenance-friendly features; excellent interchangeability of parts
  • Horizontal and vertical constructions to allow flexible pump station designs
Main applications
  • Water abstraction
  • Water transport
  • Desalination
  • Water treatment
  • Water supply and distribution
  • Irrigation, drainage and flood control
  • District cooling / heating

An efficient solution for pumping raw, clean, sea and brackish water

Main design features
  • Double volute for all sizes with innovative cutwater for minimum radial load pulses
  • Multiple hydraulics per volute optimized by Computational Fluid Dynamics (CFD)
  • 360° bearing bracket with grease or oil lubricated bearings for 100 000 bearings life time
  • Finned bearing bracket equipped with maintenance-free bearing isolators; fan cooling option for optimum bearing performance
  • Dry shaft design

Optional features

  • 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
Impeller wear ring
  • Shrink fit and axially secured
  • Offers additional impeller protection
  • Reduced maintenance cost in heavy duty applications
Seal plan options
  • Plan 11 as standard, with seal plans 31 and 32, with cyclon separator or with external flushing source

Standard and Configured SMD

To meet the demands of the individual applications, the SMD benefits from a best-in-class hydraulic design that is combined with two specific mechanical envelopes:

  • Standard SMD, focused on municipal water treatment, supply and distribution where typically a higher level of standardization is required, allowing the most cost effective solutions and shortest lead times.
  • Configured SMD combines standardization and modularization to offer a number of configurable options to meet the most common requirements of the water abstraction, transport and desalination industries.

SMD axially split casing double suction pump – standard and configured versions

Vertical arrangement
  • 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
