This document specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration, and verification of the airborne noise emission of liquid pumps or pump units (see 4.1). It specifies the noise measurement methods and the operating and mounting conditions that shall be used for the test. Noise emission characteristics include emission sound pressure levels at specified positions and the sound power level. The determination of these q...view more

This European standard specifies methods and procedures for testing, calculating and determining the Energy Efficiency Index (EEI) of rotodynamic glanded single pump units for pumping clean water, including where integrated in other products.
The pump types and sizes covered by this standard are described in the normative Annex A.

This document covers pump units consisting of:
-   one single or several rotodynamic water pump(s), including where integrated in other products, and driven by a motor system, consisting of an electrical motor and
-   either a terminal box which only enables to operate the pump unit at constant motor stator frequency and thereby (nearly) constant rotational speed,
-   or a CDM (Complete Drive Module) which enables to operate the pump unit at variable rotational speed depending on a varying demand o...view more

IEC 60335-2-51:2019 is available as IEC 60335-2-51:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60335-2-51:2019 deals with the safety of electric stationary circulation pumps for household and similar purposes intended for use in heating systems or in service water systems, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances. The hy...view more

This document sets the requirements for conducting and reporting the results of a pumping system
energy assessment (hereafter referenced as “assessment”) that considers the entire pumping system,
from energy inputs to the work performed as the result of these inputs.
The objective of a pumping system energy assessment is to determine the current energy consumption
of an existing system and identify ways to improve system efficiency.
These requirements consist of

This document describes hydraulic performance tests (including cavitation tests) using a small size pump (centrifugal, mixed flow or axial pump, hereinafter referred to as a "model pump"). This document is used for pump acceptance tests with a geometrically similar model pump to guarantee the performance of a large size pump manufactured for practical use (hereinafter, a "prototype pump"). This document, however does not preclude a temporary assembly inspection or other tests on the prototype pu...view more

This standard specifies the minimum requirements for the design, manufacture and testing of pumps for cryogenic service (i.e. for operation with cryogenic fluids below -10°C). This standard covers centrifugal pumps. However the principles may be applied to other types of pumps (e.g. reciprocating). This standard also gives guidance on the design of installations. (See annex A). It does not specify requirements on operation or maintenance.

This European Standard covers glanded water pumps for pumping clean water, including where integrated in other products. Pumps designed and produced as low duty pumps for pressures up to 16 bar for end suction pumps and up to 25 bar for multistage pumps, temperatures between -10 and +120°C, for clean water, in all kinds of material.
