What is BS EN ISO 9906:2013?

BS EN ISO 9906:2013 is a technical standard that defines the requirements and performance characteristics for centrifugal pumps. It provides guidelines for pump manufacturers and users to ensure reliable and efficient pump operations. The standard covers various aspects including hydraulic performance, mechanical performance, NPSH (Net Positive Suction Head) requirements, and testing procedures.

Hydraulic Performance:

In the context of BS EN ISO 9906:2013, hydraulic performance refers to the pump's ability to deliver fluid at the required flow rate and head, while maintaining the specified efficiency. This aspect includes evaluating the pump's capacity to handle liquids with different viscosities, variations in flow rates, and operating conditions. Ensuring satisfactory hydraulic performance is crucial to meet the intended application requirements.

Mechanical Performance:

The mechanical performance of a pump focuses on its structural integrity and functional reliability. BS EN ISO 9906:2013 specifies requirements for components such as shafts, bearings, seals, and couplings to ensure their durability and safe operation. It also outlines standards for vibration and noise levels, which are essential factors to consider for optimizing pump longevity and minimizing potential failures.

NPSH Requirements:

NPSH stands for Net Positive Suction Head, which measures the pressure available at the pump inlet to prevent cavitation. Cavitation can cause damage to the impeller and reduce pump efficiency. BS EN ISO 9906:2013 outlines the NPSH requirements that need to be considered during pump selection, installation, and operation. Adhering to these requirements helps prevent issues related to cavitation and ensures optimal pump performance.
