Drinking water certificate

Drinking water certified

CPE fits perfectly for all water applications, also fulfilling the highest standards related to drinking water applications. The CPE pump has NSF61 and NSF372 drinking water certification. The drinking water certificate is valid for Duplex stainless steel (ASTM A890 3A ) CPE pumps equipped with an NSF-certified mechanical seal.

Main water applications

CPE pumps can meet the process requirements in a variety of water applications:

  • Water treatment (inlet, flocculation and sedimentation, DAF, filtration, backwash, outlet)
  • Water supply, distribution and boosting
  • Desalination

CPE pump is NSF-certified for:

  • Pump sizes up to 32-8
  • Duplex material construction
  • NSF-certified mechanical seal
  • Standard threaded impeller fastening without additional impeller locking screw
In the name of efficiency – the new CPE ANSI pump range

  • Auxiliary applications
    The complex processes performed on a typical FPSO rely on the performance of dozens of pumps handling a variety of liquids under widely varying process conditions.

  • Flood control
    Climate change is challenging natural disaster prevention. When water runs off the land in large quantities, Sulzer’s comprehensive range of pumps provide reliable, cost effective and efficient solutions for flood control.

  • Irrigation
    We provide pumps for the water supply for gravity and pressurized irrigation systems. For these applications, we offer vertical and horizontal pumps that are especially constructed to highly challenging pumping and energy efficiency requirements.

  • Municipal clean water supply and distribution
    Getting drinking water to all parts of a distribution network involves many challenges along the way. From the water treatment plant through pumping stations and beyond, Sulzer pumps lift and move the drinking water to bring it to its destination at sufficient flow and pressure.

  • Water intake
    Water supply is vital for our daily life. To abstract the water at the source, be it the sea, river, lake or dam, water intake pumps are needed. Sulzer offers a range of pumps that are specially engineered for such applications.

  • Water transportation
    Water transport pumps are pumping large volumes of water over mostly long distances and high geodetic heights to geographical areas or industries where it is required for different purposes. We offer various configurations according to your needs.
