Pump noise level
Pump noise level
(OP)
I have some considerations about pumps noise. There are some applications where noise is very unwanted and we need to find possible noiseless solution. For the choicing noiseless pump I consider as important:
1) motor size, efficiency, motor speed
2) pump efficiency, duty point
3) pump design (type)
Could you advise which type of pumps would have less noise in general and opposite way - which pumps are much more noisy than others?
Do you have some experiences how to reduce the noise by using special accesories?
Best Regards,
Slawomir

RE: Pump noise level
Cantrifugal pumps are smooth and often the pump itself is low noise. Piston pumps are not good, but screw pumps are often quite quiet also. Pumps are easier to jacket as so long as there is flow they don't really need cooling.
After that you need acoustic housings - I've fitted them and they are a complete pain, but if you need them to satisfy someone they work. You still need some air flow.
Otherwise go for a water cooled jacked pump and motor and take the nosie of the cooling fan somewhere else, or use a constant supply of cool water from somewhere either directly or via a HX.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)
