The Gorman-Rupp ‘Ultra V’ series of wastewater and sewage pumps reduce the ‘carbon footprint' of a standard pump installation. Australian distributors for Gorman-Rupp, Hydro Innovations , claim that the new series of pump is up to 20.6% and more efficient than industry the ‘standard’ self priming centrifugal wastewater pumps that are put on similar duties.

Company spokesperson for Hydro Innovations, Garry Grant, said that because the pumps are more efficient than all other designs, smaller motors could often be used, and less energy would be needed at the duty point in all cases. This will reduce energy costs and the carbon footprint (C.F.) for any application. He also said that the further one looks into using this style of pump compared to conventional thinking (using submersible pumps), the greater the carbon footprint gap becomes.

When operators use submersible pumps, they are faced with having to replace wear-rings to maintain peak efficiency. To do this, they need to remove wet well lids, employ an electric crane or winch (adding to energy costs and carbon footprint), clean down a pump dripping with sewage (usually a pressure cleaner again adding to costs and C.F.), then send it to the workshop for a wear-ring change (often by vehicle adding to cost and C.F.).

This is of course, not an easy task, so pumps are generally left for as long as possible between wear ring changes. This is the hidden cost. As the wear-rings wear, the pump is losing efficiency and operating for more hours during the day (again adding to costs and C.F.). Further to this, as wear-ring clearances open up, pumps block more often, needing operators to lift them up, clean them and remove the blockage (again adding to cost and C.F.) Garry Grant explained.

With the Ultra V, clearance adjustment is done externally, without needing to open the pump, without disconnecting the drive and without removing the pump from the piping. Clearances can be adjusted by one person with two small spanners, in under 5 minutes, with no crane or winch, no cleaning device and no transportation vehicle. If this scenario occurred several times per year at multiple installations the cost savings would be huge and the carbon footprint gap between the two systems would also be quite large.
