A Dura peristaltic hose pump was selected in place of a progressive cavity pump at the Sioux Falls Water Purification Plant in South Dakota USA.
The progressive cavity pump would not have been able to handle the lime slurry being pumped as the abrasive and high solid content would have caused unwanted downtime and increased operating costs.
Dura peristaltic pumps are designed to contain the slurry completely within the hose, while the no-moving parts design eliminates any risk of clogging or corrosion.
A Dura 35 peristaltic hose pump capable of pumping up to 5.5 m³/hr at pressures up to 12 Bar was selected, which more than met the Sioux Falls plant’s requirement of pumping at just over 4 Bar, 24 hours a day and 7 days a week.
The small footprint of Dura pumps also helped with the installation as the Sioux Falls plant did not have room for a large pump.
Global Pumps is the Australian and New Zealand distributor for the Verderflex Dura peristaltic hose pumps and spares.
