Try a softer insulation material , mount the pump outside in a insulated box . Make sure you use thick material. Do not mount it on the case. The rubber you used is to hard and as somakes little difference. Good video though, shame it was not as good as you inticipated it to be.

Thanks for the thought provoking video. I think much of the noise it due to the pipes tapping on the case and other rattles. I have a similar heater and I love it iny small van I got some bitumen car body sound deadening sheet and stuck it to every flat surface I could find within the case. Also wrapped the pump in it like you did. I did away with the rubber bracket and wrapped the pump in strips of Karimat foam and just jammed the encased pump into the space. I put this soft neoprene like foam sheet in all places where pipes touched the case. It's a lot quieter and the ticking is a soft dull tone. Acceptable but I'm still looking for ideas. Potting the pump in silicone is my next idea but I'm looking for examples first. Nice video thank you for your efforts.

My Dad had some success quietening the noisy pump by wrapping it in neoprene foam, then dangling it from small rubber bungies which helped isolate it from the heater body, I mean it still clicks but not much of the sound makes it from the pump to the rest of the heater. The weird thing is, I've got a Japanese paraffin heater which uses a similar solenoid dosing pump, but for some reason that makes no discernible noise at all.

I did this using roof and gutter neutral cure silicone. It was a layer about and inch thick around the pump body, once cured clamped in a box similar to yours and its barely audible. Problem solved!

Great idea using the box but if you had used acoustic wadding or quilting rather than hard rubber it would improve the sound reduction hugely. In the example here the pump sound transfers easily through the rubber to the outside box and onto the outer heater casing so not much if any change. Enjoyed the video and thanks for posting

What I did was bought a silicone mold making kit. One that xxx toys could be made of soft. An taped the hose ends. And the plug part. An just got a Tupperware container. And encapsulated the pump. Than with a razor blade. Extracted to my tape areas to expose the plug an each hose end. Plugged it up to the hoses an plug. An just stuck it in the heater an closed it up. I didn’t worry much about the pump getting to warm due to its electrical workings or what not. Due to when it’s used it’s cold in general. An never has an issue. So it’s kinda floating in its lil spot inside the heater inside of a soft silicone block

From what I do know about soundproofing. You may have two issues . One is the rubber you used is probably still allowing the vibration from the injection pump transfer to the outer metal case . The other issue is the plastic plug is touching the plastic housing when you put the lid on , that allows the vibration to transfer to the plastic box . Also same with the hose ends . Might I suggest trying to use sound dampening materials for example put it in a box that is twice the size of the plastic box and use cardboard egg cartons on the inside walls of the box then find a block of soft foam to mount it too inside the box , run the hoses through that box without touching the sides of the outer box but through some soft foam . It won’t fit inside the metal container but it should still be as quite or better .

Try closed self foam insulation like you use in HVAC. It’s black in color and you can get it in different sizes. You should be able to simply wrap the insulation around it and zip tie it to keep it closed all done, faster and cheaper.

@raywhite5523 2 ай бұрын

Ps. Maybe try a less dense sound absorbing material. Like a modern rock wool material, you can get fireproof/ heat proof versions. The rubber you used maybe transferring the noise more because it is so dense, also van sound proofing. I am thinking of getting one,and I am thinking like you of the noise. Keep on thinking spot on.

Try a Decibel meter at a set distance before and after. Try encasing the pump in a softer medium ie. foam rubber. Bear in mind any hard surface in contact with the sound source will transmit sound. interesting video though.

Encase it in silicon sealer and use silicon to stick the box to the heater. But be careful with the electrical contacts as silicon setting gives off fumes which cause steel to rust so I would wrap the plug with insulation tape.

the only way to beat this is to hang the pump from a frame on fishing braid. may I add that the exhaust recomendations are no longer than 2 meters in length. and the green fuel line puts extra strain on ther pump as it gives and expands each time the pump pumps making the fuel injection less effective, almost everyone replaces it with the hard 2mm core nylon fuel line that doesnt expand as the pump pumps. There are also no fuel line clips on the fuel hose another saftey issue to note. the green fuel line has been known to perish and split esspecially around the exhaust outlet, this could cause a fire. you will also need a fuel filter installed before the pump, most heaters come with one. as you have it set up I honestly wouldnt put it a family members house without at the very mimimum doing these saftey upgrades. and please make sure you install a carbon monoxide alarm. some titanium exhaust wrap double layered may also be advantageous to keep the hot exhaust from damaging the fuel line or to protect the hands of little ones if they should grab it? it is available on Amazon.co.uk or ebay. you can also searh either site for the Diesel Heater fuel line upgrade kit it costs about £12.00

George M ..I'm researching tricks for when I buy a diesel heater for my small caravan, (17ft.Oasis)and when I saw your link, wondered if it was the one I had already watched, and it was. I think I will settle on this one (in your link) as it seems to have the most feasible explanation for getting rid of the vibration noise. The elastic suspension shouldn't transfer any vibrations and the insulated box should get rid of the rest of any noise. I'm thinking about installing it in the front boot of the van for easy access (I'm partially disabled) with a removable fuel tank so as not to risk spilling diesel, and having fuel filter and pump where it will be easy to change when necessary. I could even mount the pump and filter on the A frame of the van, out of the way.
