D5 Next minimum speed ?

mercredi 16 février 2022, 22:53

hi i just saw a 2019 video about the D5 next and it points that the minimum speed of the D5 next are 1800rpm while regular D5 are more 400rpm.

cannot find this information on the product page or in the documentation.

anyone got the information ? and the noise level ??? (i'm running my 2 pumps at their minimum speeds for silence)

thanks

Minimum speed is 1800, but that should be virtually inaudible.

What will cause/eliminate most pump noise is how well you isolate the pump from the mounting points, to minimise vibration transferral.

All Aquacomputer D5 Pumps have a minimum rpm of around 1800-1900.
Official Statement is, that it makes no sense to run the pumps below 1800 rpm, because the flow rate will be too low.

If you buy a D5 pump from a different manufacturer, you can go below the 1800 rpm.

just out of curiosity, the limit is 1800 signal RPM (900 real RPM), or really 1800 RPM?

1800 seems to be pretty high as a low limit, but 900 looks to make more sense.

at 400 rpm, there's barely a trickle of water so it's totally worthless unless you only do simple office tasks.
