The whitepaper has been prepared by engineered pump solutions provider Hydro Innovations, and has been designed as a guide on ways to improve or even eliminate some of the dangers associated with working on or around wastewater pumps.

Firstly, they maintain that using Gorman-Rupp self-priming centrifugal pumps eliminates the dangers of working over heights and working over water usually associated with pumping wastewater with submersible pumps. Because the pumps are located high and dry above the wet well, operators do not have to be exposed to the dangers of open wet well pits when monitoring, inspection or maintenance is necessary. A correctly engineered solution will also eliminate the need for working in confined spaces.

Also, because maintenance can occur while the pump is still connected to the pipe system, and no cranes or lifting devices are needed, the dangers of working with heavy swinging weights and cranes are eliminated. And when pump clearances need to be adjusted, Gorman-Rupp V Series pumps allow operators to make adjustments externally, without removing the pump from service and without having to come into contact with the pumped fluid. To adjust submersible pump clearances, operators need to open wet well lids, use a lifting device and man handle pumps that are covered in the pumped fluid (which could be corrosive, contain sharps or be full of bacteria).

The Gorman-Rupp Ultra V Series pump has been built with operator safety as a high priority. These pumps feature pressure relief valves, burst disc flap valves that can uniquely be replaced without opening the pump, and the safest fill port cover of any self-priming pump on the market. These features and others, separate Gorman-Rupp as the leader in self-priming pump technology.
