These are very strong, in fact I've never encountered magnets as strong as these.
The trick is to get them apart wider than the polystyrene blocks that temporarily separate them. I placed a wooden wedge to get them far enough apart to completely separate them but got a slight nip. I reckon you would have a real hard time separating them if you misjudged the manouver.
When mounting them have someone else hold the "dry" one behind the glass, then slide the pump with the other one towards the dry one. It's a 2 person job to do it safely IMO.
They do work well though...
