I thought something was not right, I just realised what it is.
I replied to a post and typed sorry if its not what you want to hear, then I was thinking I am sure I have done that before. lightbulb moment. Its in my signature, but signatures are not showing even though it says in my profile to always show signature, so is the forum slightly broken?
I never said 10m of cable was safe, I said that it was decided that all pumps will come with 10m Of cable and a plug fitted. You could have 50m of cable if you want, the longer the cable is the more chance you stand of damaging it, that is why you should use SWA cable. Or on the flip side, if SWA cable was not required why do your sockets have it?
I really do wish you luck asking a pump manufacturer to make you a pump with 30m of cable, they are not allowed to, and also it would be cost prohibative (to you) since they would have to alter an entire production run for just one pump.
I am sorry it is not the answer you were hoping for.
The cable that comes with a pump is actually "Flex" (Ok, its "rubber" but it is designed to be used safely underwater) As it is rubber it is only intended to be used in water and connected "locally" to where it will be used. It does not have any mechanical protection. This means that if you were to use such a cable over 30m in your garden, today you know where the cable is, in a few months when digging in your garden you can easily slice through the cable. What you should do is to install a Steel Wire Armoured cable from your existing socket to the new socket location. As the name implies a SWA cable is not easy to damage or cut and can easily survive being hit with a spade. (The SWA should also be directly buried underground as that is what it is designed for) Ideally, you should install a complete SWA cable, but you can get "kits" NEVER use "extensions" If you do not feel confident to do this, then I suggest you get an electrician in to do the job for you, and instead of one socket why not have several to allow for future expansion. (A U.V.C. if required, or some decorative lighting on a timer?)
To directly answer your original question, no manufacturer makes a pond pump with 30m of cable, in years gone by pumps had a 3m of cable then it was decided that all pumps should have a plug fitted and a 10m of cable (Often 3m was a bit too short as you could easily lose the 3m going across the pool floor up the side and then.......)

Sorry to say this but I doubt it, people move on in their lives, and the sad thing is forums are not as popular as they were (yes people pop in have a read, find an answer and...............go) but as there are less and less questions to be answered people drift away.
Unless you were to ask Oase is there such an item as you require (and pay lots of money for it) I would suggest you make your own. As you in effect have a "wall" with a hole in it (I am not that familiar with Oase filters) could you not cover said hole with a "lid" from something* and silicone it in place? Obviously you will have to empty the filter and dry the side where the hole is and then silicone in place your lid.
