Commercial Installations

Here's John Mitchell swapping a pump in a commercial boiler house of a large sheltered accomodation scheme we look after. The scheme was built in 1984 so the old Crane pump replaced lasted about 27 years. There are two pumps; a duty pump and a stand by pump. Each six months when we carry out maintenance we switch over the duty pump so they wear evenly and don't seize. The orange coloured pump below is one of the original Crane pumps which are now obsolete hence the new model we are fitting. The new pump is fitted on 3" flanges and has a maximum speed of 2800 lt / minute. The rest of the system comprises of 3 Hamworthy boilers all linked together and on a shared flue system. The main system pipework is in 3" steel which circumnavigates the ceiling void of the upper floor of the building, dropping down to feed each flat in groups of 3 {ground floor, 1st floor & 2nd floor} where it enters each flat in 22mm copper tube. I enjoy this type of work as it is what I was trained in as an apprentice many years ago. We are always keen to quote for this type of work.
