Shower water pump

It was installed with an idea to increase pressure in the heating system but the theory didnt really work out in practice. Was installed in 2022 or 2023 but was actually on only ~6 times for about 1 minute each time (or so), basically whenever plumber was around. Removed from system ~a month ago when servicing boiler. Its from screwfix, new one costs ~200, selling low as you are obviously taking a chance on an used item but it should be as close to new as it can get.. Cant guarantee it still works but again, price should reflect the gamble. Please dont ask me technical plumbing questions - i know nothing, refer to specs on 2nd/3rd photo. I live in Tallaght/Dublin, will not deliver, you have to collect.
