My grandson has dropped the pump resulting in it coming apart. I have no idea where the parts go. Please can any of you clever people help? There’s are the parts I’m left with.
Firstly, it's a pressure release valve to ensure the airbeams are not overinflated.
My Kampa pump doesn't have one, so I'm using my engineering background to best guess how that should be assembled.
I would expect the column that is perpendicular to the bayoneted inlet and outlet to be where the spring and valve shaft should reside, and that it has a removable cap. That said, it's likely that the cap was only ever intended to be fitted once at manufacture and has a snap fit that may be a struggle to remove, it may on the other hand be a screw on cap.
Assuming you can get the cap off the valve body, the flat disc of the valve would likely go in first, with the spring on top of it around the shaft. The cap may have a inside guide hole for the thin shaft at the end of the valve to fit into. The cap would then be used to keep the assembly together.
If you can't get it reassembled, Go Outdoors/Millets/Blacks do a spare that looks identical, but I'd be inclined to take pump/hose along and ensure suitable fit. The other thing is that I can't find the release pressure for that valve, but they do say compatible with pumps that fit tents with 7psi airbeams! Over inflating airbeams can be disastrous and result in damage, so extreme caution required to ensure it is of the right pressure! https://www.awin1.com/cread.php?s=440107&v=3549&q=211961&r=62066=&p=https://www.gooutdoors.co.uk/15986764/eurohike-air-tent-safety-valve-15986764
2nd option. If the pump has a pressure gauge, just discard the pressure release valve, and keep a CLOSE eye on the gauge to ensure it does not exceed 7psi, quite often the gauge only indicates on the pumping stroke and will fall back to zero after, so read when you can.
I have managed to reassemble the part, following your instructions. I rather think that something may be missing, it seems to come in and out far too easily. The pump will not work without the pressure release valve attached or, rather the hose needs that in place in order to attach to the pump. I’ve also now found that the pressure gauge isn’t working at all so it seems I’ll need a new pump.
Don’t you just love kids!
Thank you for your help Monty15, it’s much appreciated.
These pumps are cheaply made, and rarely stand up to abuse of any sort - even accidental. I was blowing a tyre up recently, and the metal fitting totally blew off the rubber hose. Another, through vigorous use, had the plastic handle snap in two. Kampa and the likes will be paying something like 2 dollars a pop for these to be made overseas. Hence not a lot of quality control will be going into them.
