Project Background

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.

The Gorman-Rupp Super T Series self-priming dewatering pump has been the world benchmark for this technology since 1963 (>55 years). These engine driven pumps are direct coupled to diesel engines through flexible flywheel couplings to ensure perfect alignment between pump and engine. These are mounted onto our “engitank” platform. This platform includes an extra heavy duty fuel tank base with a 450 litre capacity, lifting points on 4 corners, fork lift pockets, and a central lifting frame. A sheet-metal roof is provided to help protect the engine from the elements.

Advantages include:

  • Simple priming system. Just fill casing with water.
  • No complicated “add-on” priming systems.
  • Pump solid particles up to 76mm dia
  • Pump stringy materials [rags, bags and wipes] with Eradicator technology
  • Greatly reduced OH&S issues
  • Easy access for monitoring or service
  • Advanced safety features to protect operators
  • Improved maintenance features to greatly reduce maintenance time and costs, with externally adjustable clearances.
  • A variety of materials of construction to handle abrasive and/or corrosive fluids
  • Any engine brand required by the customer.
  • Choice of skid or trailer mounted configuration

The Gorman-Rupp Super T Series pump with Eradicator™ Solids Management System are a series of self-priming centrifugal pumps designed specifically for handling municipal and industrial wastewater containing stringy, difficult-to-pump, solids in suspension (such as wet wipes, rags and feathers).

They have been designed for economical, trouble-free operation, with design features that deliver superior solids handling capability and a large inspection cover to access pump internals for service or blockage removal. Gorman-Rupp Super T Series wastewater and sewage pumps have been used for pumping of WAS and RAS and for digester recirculation with great success in wastewater treatment plants around the country, as well as food process plants, paper mills and other heavy industries. The Eradicator™ system advances the solids handling capabilities of this range.

Advantages include:

  • Ability to mount high and dry above the wet well [not in it]
  • Self-priming to 7.6 metres
  • Low cost of ownership
  • Greatly reduced OH&S issues
  • No cranes or hoists for access
  • Easy access for monitoring or service
  • Advanced safety features to protect operators [such as the lightweight inspection cover-plate]
  • Improved maintenance features to greatly reduce maintenance time and costs, with removable rotating assembly
  • A variety of materials of construction to handle abrasive and/or corrosive fluid.
  • Sizes 2” to 10”, with flows to 200 L/s and heads to 40 metres.

Gorman-Rupp T Series and Super T Series self-priming centrifugal pumps have been successfully pumping municipal and industrial wastewater for over 5 decades. Over the past few years, with the introduction of wet-wipes and higher safety standards, the need for “choke-free” pumping has led to the development of pumps able to handle wipes, rags, rope, undigested hay and other stringy materials better.
Introducing the Eradicator Plus, for those extreme-duty applications where debris like trash bags, wipes, mop heads, rags, hair, industrial by-products, and agricultural wastes are present. Specifically engineered for cutting and tearing organic solids that enter the pump, the Eradicator Plus is Gorman-Rupp’s most aggressive solids-handling pump.
The Eradicator Plus is equipped with a continuous vane impeller in hardened iron, and an extra-thick G-R Hard Iron wearplate which is equipped with an oversized lacerating tooth that is designed to cut and shred organic solids before they enter the interior of the pump.

Advantages include:

  • Ability to mount high and dry above the wet well [not in it]
  • Self-priming to 7.6 metres
  • Low cost of ownership
  • Greatly reduced OH&S issues
  • Cut and shed solids that would block other pumps
  • Easy access for monitoring or service
  • Lightweight cover-plate for safe and easy access to pump internals
  • Advanced safety features to protect operators
  • Improved maintenance features to greatly reduce maintenance time and costs, with removable rotating assembly
  • A variety of materials of construction to handle abrasive and/or corrosive fluids
