I have used the Jebao return pumps for many years and have been very happy with them. I am not comfortable ordering from Aliexpress, so I have purchased all of mine on Amazon.com. They fit all of the requirements you listed. Some people have reported problems with them after some time, but I have never had a problem with them. I also think they are getting better with each generation. I am currently using one of the Jebao DCP return pumps and really like many of the new features.
