Sealless & ISO Standards

The International Organisation for Standardisation is an independent organisation that oversees, creates, and promotes internationally accepted standards for numerous industries, ranging from agriculture and manufacturing to technology. ISO safety symbols are recognised across all countries and in all languages for increased hazard awareness and safety compliance.

Think Sealless Standards ISO


  • The ISO 15783 standard specifies the requirements for sealless rotodynamic pumps which are mainly used in chemical processes, water treatment and the petrochemical industries. It includes design features concerned with the selection, installation, maintenance and operational safety for magnetic drive pumps.
  • The ISO 2858 Standard refers to all end suction centrifugal pumps and specifies the main parameters and the pump designation. It details the principal dimensions, mounting details and nominal duty point of end-suction centrifugal pumps having a maximum operating rating of 16 bar.
  • The ISO 5199 standard specifies performance requirements including minimum bearing life and construction features such as general layout. In some aspects, including maximum permissible vibration levels, ISO 5199 is more stringent than ASME B73.1.

HMD Kontro pumps comply with all relevant aspects and specifications of ISO pump standards.  In addition, our manufacturing and business processes also comply with ISO 9001, 14001 and 45001 standards. Additional details are shown on the certification and compliance page of our website.
