The nitty-gritty on Bondi WWTP’s tough pumps
Project Background
When Sydney Water’s Bondi Wastewater Treatment Plant needed repairs to two Gorman-Rupp Grit Pumps, authorised Australian distributor Hydro Innovations was called upon.

Why Was Authorised Australian distributor Hydro Innovations Called Upon By Sydney Water
The plant recently had call to make repairs on two of the pumps and relied on Hydro Innovations, as the authorised Australian distributor for Gorman-Rupp pumps, to carry out repairs with genuine parts and to specifications as per operations manuals. Repairs were able to be turned around quickly because Hydro innovations had all parts for the repairs “off the shelf”.
The Bondi plant has been using Gorman-Rupp pumps in this application for more than 30 years. During this time, Gorman-Rupp has developed harder materials to cope with abrasive applications like this [pumping grit and sand]. Sydney Water was one of the first organisations to recognise the benefits of these harder components, which result in less downtime and longer intervals between repairs.
The Results
Being self-priming, pumps are able to be located above the water, in a safe and easily accessible position, allowing quick and easy monitoring and repair. Cranes are generally not required to access pumps, and inspection covers allow operators to gain access to pump internals without removing the pump from the pipe system. A patented internal clearance adjustment system also allows one operator to safely adjust clearances in minutes with just two spanners, keeping pumps at peak efficiency for the life of the installation.
Pumps are available in sizes from 50mm [suction and discharge] through to 250mm, with flows from just a few litres per second [L/s] through to 200 L/s. A variety of materials of construction allow pumps to be “tailored” to individual applications.
