Engineers from the Eraring Power Station, near Lake Macquarie in NSW, have chosen a Gorman-Rupp Ultra V series wastewater pump for one of their sumps to overcome continuing maintenance issues with previous pumps.
They wanted their pump to handle 75mm spherical solids while delivering 45m of head at the desired flow rate of 35 litres per second.
The Gorman-Rupp V4A60-B (Ultra V Series), distributed in Australia by Hydro Innovations, is a self-priming centrifugal pump – one of the most advanced on the market.
Being self-priming, they can located high and dry (up to 7.5m) above the waste water, greatly minimising confined spaces issues.
Other features include:
- A patented “self-cleaning” wear plate system to reduce blockages
- A patented external shim-less adjustment system that allows operators to adjust internal clearances in less than 4min, allowing up to four times more wear than equivalent duty submersible or centrifugal pumps.
- Easily removable cover-plate to allow access to pump internals in minutes to remove any blockages.
Ultra V Series pumps are available in three hydraulic sizes covering flows from 10L per second through to 120L per second, with heads of the single stage pump to 50m, and heads of the two-stage version of the pump to 95m.
