Upgraded Waste Water System for a Food Manufacturer
The Challenge
A food manufacturer approached Dura Pump for a new waste removal system. Wastewater from their factory was continually blocking their gravity system, so they wanted an above-ground pump system to remove the waste water from a manhole, and then pump overground to their treatment plant.
An industrial submersible pump could not be used in this situation due to the size of the manhole the liquid was being extracted from.
The Solution
The solution that Dura Pump provided was to build a skid unit with two Rotomec KSM vortex pumps, controls, valves and manifolds – which made a self-priming unit able to suck the liquid out of the manhole. The complete unit was built up and tested in our workshop, ready for quick and easy installation on site. We used Rotomec KSM pumps because they have a 75mm clear passage and therefore could handle the solids in the system, which could then be filtered out by a duplex filter, also mounted on the skid.
The frame was galvanised and the control panel was mounted in an enclosure so that it could be installed outside. The control panel included hand-off-auto switches, run and trip lamps, a high level alarm, and a main isolator. The controls also automatically alternated pump duty, monitored levels and brought in the standby pump when needed.
The system was delivered to site for our client to connect up to their system, as they had on-site engineering capabilities in their team.
The Outcome
The solution gave our client an easy way to overcome issues with their gravity system, avoiding future blockages, reducing downtime in their factory and ultimately saving money. Also, it meant the wastewater could still be processed in their plant, reducing wastewater disposal costs and ensuring longevity of the system. Where solids need breaking down rather than filtering out, a waste macerator pump can be an alternative.
