Steering pump compatibility

[BAlexandrov]

Hi guys!
My son have Mazdaspeed3 1 gen - 2.3 MPS Turbo (BK14) 2007.
There is some stutter when turning the steering wheel so I want to change the steering pump.
The problem is that I cannot find the right one in Europe or China. Only 1 such model in USA.
There is error in the part catalogue. Supposedly the number is B37F-32-600A but this gets only pumps with attached reservoir.
Mine is with separate reservoir. Exactly looking loke in the part catalogue and in the service manual attached.
The same one, used is posted here https://rrr.lt/en/used-part/bdj9335-b37f-32-600a-mazda-3-i-power-steering-pump but I'm looking for a new.
This is not the right pump - https://alvadi.ee/item/lauber-55-6151?sv=1
This is not right too - https://www.aliexpress.com/item/1005009945230694.html

Do someone have experience finding the right pump or thoughts if the reservoir can be detached and the tube to be mounted there instead?

Only this one looks similar but is only from USA https://www.ebay.com/itm/124986011735

Can someone give some insights?

Thanks! Seems similar yes.
I've forgot the VIN: JMZBK14L681733587 and according to catcar.info actually the right one is B37F-32-600B (not A)

I cannot find anywhere new parts with either B37F32600R0C or B37F32600B looking right.
Some help to find oem or aftermarket new one? Or thoughts on rebuilding (it's not leaking).

Rebuild it. It’s really not that hard rebuilding a lot of parts that nowadays are considered trash because a bearing went bad. I’ve rebuilt Alternators, PS pumps, AC compressors, secondary air pumps, and a few other accessories that are common on gas and diesel engines. It saves you the hassle of usually having to eat a core charge or ship a core out. In my experience lots of remanufactured parts are just using the same cheap rebuild kits you find on RockAuto anyway. Sometimes the remanned parts fit the car physically, so they are called a direct swap, but are from a different model so certain things don’t line up or play nice electronically, and by rebuilding yours you know everything be correct spec for your purpose.

It’s also something you and your son can enjoy together. I have many fond memories of working on cars with my dad when I was teenager and even now at 30yrs old. In fact those are the fond memories that keep me from saying “fuck this car” and flicking a lit match in the gas tank sometimes when car work gets physically and emotionally painful.

The Speed6 has a seal kit, and are known for the PS pump to be problematic due to heat. They sell a seal kit for it, I can’t be certain it works for a Speed3 though at $7 I’d be willing to take the risk.

Yes, working it out with my son is what drives me. We've already changed the belt, pulleys and the fluid together.
The seal kit is available, but I am not sure if it would fix the problem. It's not leaking, just when parking when the wheel is turned a stutter or little steps are felt. I think that the pump mechanism is not working right or the rack...

PS. I'm not very experienced with the repairs but have a lot of info and am collecting service manuals for Japanese cars more than 15 years already

Looking at these pump for CX-7, they look very similar to mine and the one is with, the other without a reservoir but look the same. So probably each pump with attached reservoir can be used just placing the old tube there? What you think?

the one ending in 600A, that looks like the PN I found and isn't it the PN you said it's supposed to be? that's the way I'd go
