Problems with flexible connections at the inlet and outlet of water pumps
Thread Content
Seeking advice: For a 5.5 kW centrifugal pump with a rotation speed of 2900 revolutions per minute, is it necessary to install flexible connections at the inlet and outlet? Are there any relevant regulatory requirements? Waiting online! ! !
There should be no mandatory requirement; it’s 5.5 Kw, the pump isn’t large.
The speed isn’t high, the power isn’t great, and the medium is ordinary; it’s not necessary.
Thank you! Are there any relevant specifications for reference?
There are no similar standards in the pump industry; it’s not clear whether any such standards exist. Those that are this small generally don’t have vibration isolation joints
Such a small device can be left uninstalled. You can pretend to be rich too, you know.
Personally, I think it has something to do with the situation of pumps and front-end as well as back-end devices； If the pump is located on a steel platform (a steel platform, not a steel structural foundation), the pump will experience significant vibration; it is recommended to install flexible connections ； If the pump and the front-end storage tank are on different foundations, especially if the front-end storage tank is prone to settlement, it is recommended to install flexible connections ； For your operating conditions, the decision of whether to install it should primarily be based on the need to protect the equipment, rather than adhering strictly to regulations.
