Project Background

Gippsland Water provide quality Water and Waste Water services to the Gippsland Region of Victoria. At their Morwell Waste Water Treatment Plant Gippsland Water have utilized 2 x Gorman Rupp Ultra V series 3” pumps as the inlet works pumps for the plant.

Since having the upgrade installed in Pump 1 on Tuesday 26/09/23, we have left Pump 1 as the duty pump and have not experienced any pump blockages

Why did Gippsland Water select Gorman-Rupp Eradicator upgrade kit for this project

Until December 2020 the inlet works had a muncher prior to the pump suction lines. Following multiple position changes and two catastrophic failures, the last being the bottom bearing failing resulting in 1 side slipping down and chewing out all the teeth. The decision was made to remove the muncher entirely from the inlet works. This meant the Ultra V series pumps were now being asked to pump unscreened raw sewerage. The first 12 months saw a total of 114 blockages across the two pumps, roughly 2.2 blockages per week with the inlet pump closest to the forebay inlet accounting for 64% of those blockages. The added vibrations caused by the raged-up pumps eventually lead to cracking in the welds of the inlet pipework, so the plant Technician Scott Kitwood reached out to Hydro Innovations’ Regional Manager Graeme Spence, looking for a solution.

The Results

The Ultra V series pump along with the Super T series pumps can be retrofitted with Gorman Rupp’s patented Eradicator solids management system.

The Team at Gippsland Water took the opportunity to retrofit an Eradicator upgrade kit to the inlet pump with its suction line closest to the wet well inlet. Since installation 9 weeks ago the pump has experienced only one blockage!! Almost 100% reduction in blockages!!

Some comments from the Plant Operator below,
“Since having the upgrade installed in Pump 1 on Tuesday 26/09/23, we have left Pump 1 as the duty pump and have not experienced any pump blockages.

Prior to the upgrade we would notice in the trends that the pump speed would drop off on occasion (due to ragging and the VSD protecting the Pump), which would happen multiple times a day. This has since only happened once in the 2 weeks it has been running.

As you may be aware, in early October Gippsland was hit with extreme rainfall. There have also been 2 smaller events in November and December, there is a lot of data from the October event as well as the continued recovery and return to normal phase for each event over the past 3 months. However, the standout fact is that not once during the high inflow periods did Inlet Pump 1 fail or rag up, nor was there any reduction in flow or pump speed. This is an amazing outcome with multiple benefits, we are very pleased with the outcome and will look to upgrade the second pump in the near future.”

If you are looking to reduce maintenance costs, boost efficiency and lift “up-time” with your wastewater pumps, Gorman-Rupp’s “Eradicator solids management system” could be the answer.

The Ultra V Series is Gorman-Rupp’s higher pressure self-priming dewatering pump. 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:

  • Higher pressures
  • 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
