Roterande deplacementpumpar - Prestandaprovning för godkännande
This European Standard describes specified types of acceptance tests for rotary positive displacement pumps for applications other than fluid power, excluding progressing cavity and peristaltic type pumps.
This European Standard applies to the testing of pumps with and without drivers.
This European Standard covers a selection of tests to establish a uniform demonstration of the pump's ability to perform satisfactorily. It does not, however, cover all tests that may be needed for particular pump types or applications, e.g. tests for hazardous liquids or single shaft multiple pump units. Furthermore, it does not cover any noise and vibration tests, priming tests nor any hydrostatic pressure tests. Some pump types with integral relief
valves may require more extensive relief valve tests than described in this European Standard. For dosing and metering applications, further tests to demonstrate the dosing and metering abilities of the pumps may be necessary.
NOTE Extrapolation of test results to non-tested pumps is not described in this European Standard. Such extrapolation could be made for mass-produced pumps with reference to pertinent quality assurance methods and standards.
