New Invention - Pump Silencer!
I finally managed to find a way to silence the discharge pressure of my pump with Cheap parts you can find at any pet store. For years the problem with pumping in private has either been the trying to silence the discharge pressure or the slurping sound caused by the movement of the piston. Well after about a week of research I believe I have found the way to get away with pumping silently.
The materials you will need you can procure with just $5 (U.S.) at any pet or aquarium stone.
You will need:
6” of blue or black silicone aquarium tubing ,sold in 6’-8’ lengths for $3,(don’t use the hard clear plastic tubing)
A 2” air stone (I went with the 2” just for easier attachment purposes)
Velcro or electrical tape
Now, the only difficult part will be stretching and fitting the end of the aquarium hose over the pumps discharge nipple. I’m using a early version of the mityvac pump similar to a freight hand pump. There should be a discharge nipple on any brake bleeding kit you find.
Once you have completed the difficult task of wedging the flexible hose over the nipple the next step is to attach the other end to the air stone. Finally either using Velcro or electrical tape attach it anywhere it won’t be in the way on your hand pump. The whole set up will cost you maybe $6 at checkout if you already have tale at home.
Use
The air stone helps to quiet the hush somewhat but not completely.This is just a prototype so don’t expect it to be perfect. The least I have noticed was a crackling sound up to a longer and quieter “swoosh” sound. Further modifications would probably the addition of a PVC pipe with baffles. Any ideas would be greatly appreciated.
** I have also disassembled my pump and applied a greasy water based lube to cut down in friction and further silence the piston.
