Title should be a 15-60

I have a Grundfos ups 15-60 pump fitted to a boiler.
The pump pipes run north and south.
The electrical box is on the top with power grommet to the side of the electrics box that is on top.
I note that new current pumps have the electric box on the side so the pump cannot be fitted due to restrictions of pipework at the side. In other words, new pumps have electric box at side with pipes running north and south to put it simply.
My solution would be to undo the four main body locating bolts and rotate the main body 90 degrees to achieve the identical fit as existing.
Question: can this be done; assuming the main back plate is square and holes are equidistant from each other.
One other issue, the two pump existing pipes/fittings appear to be 1.24 inch diameter overall.
What do you think.

Correction existing is a `15-60 coloured Red and on the information plate is an ellipse with FR in it. France ?

To answer your question, you can certainly take out the four allen bolts and turn the new head. You are not meant to leave the electronics under the pump,though (eg south). That leaves three alternative positions. Only the pros leave the junction box underneath..!

Interestingly, perhaps, a 15/60 and a 25/60 are now exactly the same pump.

An equivalent Grundfos pump has 1.5 diameter pipes, the existing Grunfos pump has 1 5/16 inch (33mm) overall outside thread diameter.
I don't know how old this existing pump is and cannot find an identical replacement and to use a new replacement available from the stockist means alteration of piping to connect to the new pump; i.e. different pump pipe diameter and yes caliper measurement confirms that hex studs are equidistant on all four pump sides.

Both top and bottom pipes connecting to the Grundfos 15-60 pump are 22mm overall diameter.
 
You are making very heavy weather of this.

Why not buy a UPS2 15-50/60; it will fit on the same allen screws to the existing body and no, you don't need a bl**dy caliper.
