Sulzer has announced that its CPE end-suction single-stage centrifugal pump range has been granted NSF61 and NSF372 drinking water certification, showing that it now conforms to the highest standards related to drinking water applications.

The CPE pump is designed to meet the process requirements in a variety of industrial applications, such as clean or slightly contaminated liquids, viscous liquids, and fibrous slurries. With the newly obtained NSF drinking water certificate, the CPE process pump range is also suitable for water treatment, water supply and distribution as well as desalination applications. The drinking water certificate is valid for duplex stainless steel (ASTM A890 3A) CPE pumps equipped with NSF-certified mechanical seals.

The US Department of Energy (DOE) has specified the Pump Energy Index (PEI) for clean water pumps (in the range of 1-200 HP) with the target of reducing energy consumption. PEI for clean water pumps was set to ≤1.0. The CPE pump exceeds the PEI requirements as well as the design requirements of the ASME B73.1 standard.
