I have many used fountain/pond pumps. Various sizes, they work fine but may be a little slower than a brand new pump. Could be useful for someone wanting back up pumps or on a low budget. All I'm asking is you cover the postage (unless you live close enough to pick up). The pumps are either Blagdon or Libel. They may not have their original fountain attachments, hence them being good as spares.
I still also have a sealed Libel Xtra 1600 which I'm selling for ?10 plus postage.
