Today I installed my Shurflo water pump straight onto the wall of the van but when I switched it on, I couldn’t believe the noise coming from this thing! it transmitted around the full van. I realised that, ideally, these pumps should be mounted on solid floor or on any solid structural members to prevent vibrations being amplified through the rest of the structure. Pump noise was something I didn’t think about but after a while of experimenting I came up with a simple and really effective solution:
hang the pump rather than fix down with screws in order to isolate vibrations
See the rest of the water system installation here
Here’s how I made my water pump run super quiet
I found a nice trick for mounting the Shurflo diaphragm pump onto any noisy surfaces or any surface that may transmit vibrations round the van. I couldn’t find much on the net about pump mounting techniques with the aim of reducing operation noise and I certainly haven’t seen anyone use this method of mounting. If you have the same problem as i did then maybe you should give this a go…
Hopefully this helps anyone who has a similar problem with pump vibrations and noise
You should try some Dynamat or similar brand or sound dampening. They use it in professional car audio applications to prevent any vibration of the body that could contaminate the sound for the listener. With consumer products reaching easily 140db+ im sure a few patches or the mat here could easily solve your problem.
Hey Trevor, thanks for the comment! This is how I thought I’d solve it at first but the problem was with the screws used to fix the pump down. No matter how much sound deadening I used, a substantial amount of vibrations seemed to get transmitted through the screws and amplified by the wall. I’m pretty sure the Dynamat stuff is just bitumen as well. Did you see my post on sound deadening? https://vandogtraveller.com/sound-insulation-van/
Hi van dog,my brother in law mounted his pump on part of a truck mudflap that is attached to a subframe under the motorhome,you can not here it running game at all.I am just doing the same with a van I have bought,it was screwed to the wall,very noisy.cheers mike.
