Chemical standard pumps in the CNP series are single-stage, normal-priming centrifugal pumps that have been developed for use in the chemical and petrochemical industries. The pumps are characterized by standardized dimensions and hydraulic performance, based on ISO 2858. This is supplemented by smaller and larger sizes. Our series covers the full range, from simple basic variants to ISO 5199 variants and API 610-OH1 versions. The possible scope of supply ranges from individual pumps with free shaft ends to fully developed, highly integrated complete systems.

Fields of applications:

Chemical standard pumps are primarily used to pump various liquids in the chemical industry. Due to the variety of available materials, they can also handle aggressive or abrasive liquids. These pumps can handle acids, alkalis, and slightly viscous substances. Our clients currently use chemical standard pumps in the following areas:

• Conveying of process liquids

• Hydrogen production

• Chemical recycling of plastic waste

• Industry and plant engineering

• Circulation of liquids

• Refinery and offshore applications
