Greater Western Water uses Gorman-Rupp pump in water delivery project

Hydro Innovations was engaged by an engineering consultant to select pumps for Greater Western Water’s WIN project to deliver water to irrigation pivots and also to storage tanks on the north western fringe of Melbourne.

Duty points ranging from 30 to 150 L/s at a constant pressure of 68 m for the pivots and 58 L/s at 43 m up to 115 L/s at 46 m for future flows were required from the same pumps.

Why did Greater Western Water select Gorman-Rupp pumps for this project?

Hydro Innovations provided the Gorman Rupp VS6A60S-B pump with 110 kW motors. These pumps are a two-stage, self-priming pump capable of delivering the full flow ranges, either using a single pump or running two pumps in parallel. Although designed by Gorman-Rupp for wastewater handling duties, including raw sewage, the pumps are so efficient and produce high enough pressures for them to be a suitable selection for this application for Greater Western Water.

Greater Western Water was impressed by the simplicity of the solution and the great quality of the Gorman Rupp pump. Hydro Innovations delivered the pump sets coupled to the motors on galvanised steel bases ready to be bolted to the pipework and connected to power.

The results

The pumps run quietly and will deliver the flows required by SCADA reliably and without the need for an operator to be present. As they are above ground, they are easily accessed by maintenance and operations without the need for lifting equipment, confined space entry or a large crew of people.

Floating suction lines mean the pumps can operate across the changing water levels throughout the year without hassle.

The supplied pump is part of Gorman-Rupp’s ‘Ultra V Series’ range of pumps, which are available in single or two-stage configurations, giving them a pressure range between 10 and 95 m. They are available in three sizes (3", 4" and 6"), with flow ranges from 10 L/s through to 100 L/s. Predominantly a wastewater pump, they can also be fitted with Gorman-Rupp’s ‘eradicator solids management system’ to enable the pumps to handle stringy materials such as rags, feathers and wet wipes.

Pumps can operate on suction lifts to 7.6 m, allowing them to be mounted ‘high and dry’ at ground level, allowing easy and safe access for operators to monitor and maintain them.
