Potable Water Pumping Station
Thermancy has worked with the client for many years, completing projects at various pumping stations. The company is now rolling out a program to fit Acuity pump monitors.
The energy manager selected one of their largest pumping stations since it has a very high energy bill and was looking to reduce costs.
The station has 10 pumps. All fixed speed with duties of 900kw, 4584 m3/hr at 65m for pumps 1 to 9, and a duty of 1500kW, 6000m3/hr at 65m for pump 10.
The normal running combination is for 2 pumps to run during the day, 3 in the evening and 4 overnight.
The Acuity pump monitoring equipment was fitted to all pumps. After the installation of the equipment, the Acuity was used to carry out a pump performance test for each pump.
The results highlighted an issue with pump 10. The data showed that it was 18% down on efficiency.
The data recorded by Acuity was further analysed after 2 months and a series of actions were recommended to optimise the pumping operations.
The equipment is continually monitoring the pumps at the station.
Savings of over 18% from pump refurbishment
Savings of up to 5% from pump scheduling
The logged data from the Pump Monitors identified the most efficient combinations of 2, 3 & 4 pumps to run, and by running these combinations, respective power consumption savings of 5%, 4.3%, & 3.2% were achieved.
Pump 10 was prioritised for refurbishment work. A saving of 18.6% was achieved.
