pumpekrav

Pumpekrav is a Norwegian term that refers to the set of requirements or specifications that govern pumping equipment. The concept is used in procurement, engineering, and regulatory contexts to ensure that pumps meet defined performance, safety, and compatibility criteria before they are selected, installed, and operated.

The scope of pumpekrav includes selection criteria, installation conditions, operational performance, and maintenance demands. It applies to various types of pumps, including centrifugal and positive-displacement pumps, and to a wide range of fluids such as clean water, wastewater, slurry, chemicals, and viscous liquids. The goal is to ensure reliable operation, energy efficiency, and safe integration with piping and control systems.

Key elements typically covered by pumpekrav are: required flow rate and head, pump efficiency and energy consumption, motor and drive specifications, materials and corrosion resistance, sealing, bearing life, and safety features such as sediment protection and overload protection. It also includes installation constraints, such as vibration limits, foundation requirements, piping layout, and accessibility for maintenance.

Standards and regulation: Pumpekrav are often aligned with international standards such as ISO and EN for pumps and pumping systems, and may reference API, ASME, or IEC standards depending on the application. In Norway and the EEA, many pumps must meet CE marking and applicable national regulations for safety and environmental impact.

Applications: Pumpekrav are used across sectors including water supply and treatment, wastewater management, agriculture and irrigation, chemical processing, and healthcare devices. They inform procurement documents, supplier specifications, and commissioning protocols to ensure that pumping equipment integrates with existing processes and meets performance targets.
