Pump advice

[Upperllifior]

My old fishmate 9000 has broken it's impeller and I am struggling to find a replacemt as the pump is now obsolete. The kits on eBay are for a model 379 which is no longer made bbut mines a 279 which I guess is even older..
So 2 questions
Does anyone know where I can get a model 279 impeller?
What alternative pump wound you recommended. I used the current pump to power a pressurised filter (fishmate 15000) and the pond is approx 16000 litres.

Any advice welcome

No clue on where to get one. I just looked on Ebay and they had one for the 279 but it did not look right. Looks like parts are missing. No shaft etc. They want $25 U.S. plus $10. shipping.
