Very noisy loft water pump and new water cylinder...

We had a new boiler and water cylinder replacement fitted a month ago still with the old pumps. According to my stepdad, we have two different pumps, one each for our both upstairs showers. We rarely often shower at the same time. The extremely loud noises hear, are the loft pumps vibrations every time upstairs showers are turned on. This noise was the same as before, but not as loud with old system but with the new system installed, the actual cylinder inside landing airing cupboard, a few seconds after noise from a loft pump kicks in instantly from a shower turned on, then the cylinder makes a weird motor noise also, my stepdad believes this could be air lock after having new radiators installation a few days ago. Unfortunately a different plumber to boiler/cylinder installation, forgot to double check system air locks. Seems like it’s coming from or through the large silver bolt on top of cylinder, that never sounded with the previous cylinder. Cannot tolerate these loud noises just for having a shower, doesn’t make sense and please can some professional info me is this normal or can stop the noise please? I checked online for The Salamander CT Force range. I wondering if possible can use a twin pump for two showers, instead of having two bumps for both showers?
