Booster Pumping Station
The client contacted Thermancy, looking for options to reduce their pumping energy consumption.
The client knew they were wasting pumping energy since the 3 fixed pumps run with their delivery valves partially closed (throttled).
The station has 5 pumps. The fixed speed pumps 1, 2& 3 have a duty of 408m3/h at 60m, and the variable speed pumps 4 & 5 have a duty of 416.4m3/h at 60m.
The normal running combination is for one fixed speed (pumps 1, 2 or 3) and one variable speed pump (4 or 5) to run.
