Wannon Water provides water supply and wastewater collection and treatment services to over 30 communities in South West Victoria. It is their responsibility to supply fresh water, from source to tap, and to manage sewage to protect their community’s health and wellbeing.
Unlike other Gorman-Rupp technologies that are designed to clean the impeller and pass solids to the discharge, the “Eradicator Plus” cuts and tears items such as rags, wet wipes and rope that would clog other pumps.
The Problem
In 2022, Wannon Water replaced some very old digester pumps at their Hamilton wastewater treatment plant with new solids-handling pumps, as part of an efficiency upgrade. These new pumps, although equipped with rag handling technology, struggled to cope with the extra heavy loading of rags and stringy materials in the pumped media. These new pumps were blocking 2-3 times per week.
The Solution
During discussions with Wannon Water about the issue, Hydro Innovations Regional Manager, Mr Graeme Spence recommended a trial with Gorman-Rupp’s new “Eradicator Plus” extreme duty solids handling technology, the latest in Gorman-Rupp’s “Super T Series” trash and sewage pump line-up.
Unlike other Gorman-Rupp technologies that are designed to clean the impeller and pass solids to the discharge, the “Eradicator Plus” cuts and tears items such as rags, wet wipes and rope that would clog other pumps. Eradicator Plus pumps are equipped with a rugged, heavy duty continuous vane impeller constructed of G-R Hard Iron. They also come standard with an extra-thick G-R Hard Iron wear plate that has an over-sized lacerating tooth that is designed to cut and shred organic solids before they enter the interior of the pump.
The Results
Wannon Water decided to trial the new technology. At the time of writing this article, the new system has been in place for 8 weeks without a single blockage, confirming the solids-handling capability of Gorman-Rupp’s latest technology to handle these extreme applications.
The Eradicator Plus is available in three hydraulic sizes. 3”, 4” and 6”, and because the system is an extension of Gorman-Rupp’s proven Super T Series range, will fit onto the same foot-print as similar sized “standard” versions. Upgrade kits are also available for those Super T Series asset owners that are experiencing increased occurrences of clogging. And for abrasive applications, Eradicator Plus pumps are available with High Chrome impeller and wear plate.
