Pump Vibrations.

[chibi_man]

Has anyone had that annoying vibration off the WC pump? I have the DD MAG 2 pump, awesome little pump but if it hits any surfaces she will vibrate everything. I know I can buy anti-vibration gel pads or rubber bumpers, but has anyone made up something that works really well... other then suspending the pump by it's hose. I already did that, not very pleasing to most eyes.

Any holes in the base plate? If so, use a silicone-based foam, held in place with double-face tape (against both case and pump base plate surfaces). Then use bolts, washers and nuts to secure the pump in place, slightly compressing the foam.

This will make sure that the compressed foam absorbs the pump vibration. Did that to a Swiftech 655 with great results.

well theres no holes on the MAG 2... But there will be

what about silicon itself. Just make up a mold and do that. what you think?

I'm not sure about silicon; it's designed for sealing, not vibration absorption. You can try it though.

I suspect that "The Handyman's Second Favorite Tool" (Velcro as opposed to Duct Tape) used to mount the pump rather than bolts/screws would dampen any transfer to a case as well.

It might not look quite as pretty as a flush mount with screws/bolts, but even with a silicon spacer, the mounting bolts/screws are still going to transfer sound/vibration to the case.

Silicon is for sealing parts.
Velcro is for temporarely attaching parts.
Both are not designed to dampen vibration.

I use a silicon-based foam (called Rubatex - it's used in the aerospace business) to dampen vibration. Bolts and nuts are used to secure the pump to the case.

PM me if you can't find an easy solution. I'll ship some foam to you.
