Severn Trent Pumping Station
The residential property next to this Sewage Pumping Treatment Works had been experiencing problems with vibration being transferred from the pumps into their house. Mason UK designed and supplied a bespoke inertia base mounted on springs and Mason Mercer 502 Heavy duty Expansion Joints.
The control rods were installed 'just loose' (about a 3mm gap) with the pumps running at normal operating pressure. Under extreme service (with heavy rain for example) the pressure increases and the control rods limit thrust and thus prevent over-extension.
