Testbed - DESMI Suzhou
The DESMI Shuzhou testbed facilities are capable of conducting NPD verification as well as performance tests for both ROTAN and Centrifugal pumps.
CENTRIFUGAL PUMP TEST BED
?
The centrifugal pump testbed has been thoroughly upgraded since 2019 and are capable of NPD NPSHr testing, normal production verification, as well as efficiency verification and can fulfill both ISO9906 1U and ISO9906 2B standards. The test bed is constructed with a double pipeline and can test two different sized pumps simultaneously.
