Wet Well installation at Whitby
IN NEED OF AN UPDATE
The original pumps installed at Whitby STW had become obsolete so Hidrostal was asked to provide a competitors pump for hire as a standby unit. The selection was made by the customer as a like for like unit but suffered from blockages and was incapable of handling the incoming flow. Hidrostal attended the treatment works to undertake a thorough site evaluation, including discussing the pumps performance with the operators to fully understand the requirements. Following this process, Hidrostal selected four of their transfer pumps to provide the necessary performance at the site.
The Hidrostal pumps were selected due to their excellent solids handling performance. The Hidrostal screw centrifugal impeller can comfortably handle all types of sludge up to 8 percent DSC without blocking and is renowned for its rag handling capabilities.
