Pump gear what if?

Since you are rebuilding a pump, there might be wear that must be compensated at both tooth-end and sides. Don't know the original specs for the Magom pump, but tooth-end to case is probably .001" - almost touching. Side clearance is probably similar. If your case is worn it could be reworked to clean up the tooth-end area (outer diameter of the gears) - again, a very precise operation. If side clearance area is worn, the end plate could be ground flat to give a good sealing surface, but precision is key.
Since pumps are normally hand fitted during assembly, I can't predict what your success will be. A few years ago, someone on the Forum built a gear pump from scratch (don't remember who) and had some decent level of success. Maybe your repair will work.
Forgot to ask - how badly worn is your original pump? Is it not pumping well? Low flow or pressure or both?

Good luck!

Well it will work but there is no lifting power, the pump is a older magom pump still has the brass gears , I know now they make all there gear harden steal . It's funny it more as like it's working fine but there is no power
