Advice on a good SILENT pump
Hi all, so over the years iv used cheap and not so cheep return pumps, recently I have bought a 3500lp red devil pump which was silent but the head pressure was a lot less than stated on the box so that's now running my reactors. I then bought a second hand eheim compact 5000lp pump, this is great for flow but gives a load hum. Seems to be getting louder as time goes on, maybe it's coming to the end of its life?
What pumps are going to serve me for years to come? It needs to be 4000lp and silent, really silent. I prepared to pay for the right pump as long as it does the job. Any ideas thanks
