Can you use a shower pump for whole house?

Hiya, we are getting our bathroom done and have a gravity fed heating system.

We have bought a shower pump - but could this in theory be used as a whole house pump (we have a kitchen tap and bath and sink taps in addition)? If not, what is the difference/why could this not be done?

The reason being is the potential to connect the bathroom sink tap to the mains, bypassing the cold water storage tank, and being able to use the tap as a proper mixer as opposed to just hot/cold. We were advised the pump could be the solution. Thanks!

A shower pump is usually designed for a single outlet and will suffer a significant drop in pressure if you try to run multiple outlets at the same time. It'll also have a low maximum flow rate. Whole house pumps have a greater capacity and so can maintain pressure with multiple outlets running

A lot of shower pumps too aren't classed for continuous use and have a max duty cycle of 20 odd mins and they wouldn't hold up long to the amount of use pumping the whole house could entail. That and they tend to have plastic impellers that again won't stand up to that amount of use.
You do get shower pumps that can be used to service multiple bathrooms or the whole house but they tend to be on the more expensive side of the ranges and are made of brass.
