Waste Water & Sewage

Castle Pumps received an enquiry from a company who deal with the collection and treatment of domestic sewage systems and industrial waste. They were looking for a water treatment dosing pump for metering 5-10 litres of ferrous sulphate and caustic soda at a time. Ferrous Sulphate is commonly used as a coagulant in water treatment to bind particles in wastewater together to make them easier to remove, and then caustic soda raises the pH levels after the coagulants lower it.

We received an enquiry from Northern Tanks, a fabricator of fluid storage tanks and transfer systems. They were in the process of a designing a steel container which would enclose a water tank with pressure washers connected, used to wash down site equipment. Once used, the collected water would be passed through a Lamella Separator and Filter to remove any large solid particles and returned to the original water tank to use again.

Castle Pumps are always on hand to provide a solution to your pumping problems. This company contacted us because their current pumps were not performing as they should and kept getting clogged up. Space was also an issue for this customer, however, we were able to supply an ideal pump for their application which we adapted to minimise the footprint and provide an easy installation process, and minimise maintenance costs overall.

An engineering company who were refurbishing a leisure yacht needed pumps for the sewage and oily waste water tanks, but were having trouble sourcing surface mounted self-priming pumps that would fit into the allocated space, that would perform the required duties. Castle Pumps came up with a solution and provided them with a unique range of progressive cavity pumps that matched their requirements and delivered them to the engineers in just over four weeks.

Castle Pumps understand that in some situations the customer has very specific requirements including flow rate performance and drive type that the pump needs to be matched to. Here, a dewatering contractor required an engine driven pump to remove 600m³ of water from a pond in 6 hours. We were able to source the ideal solution for this application, ensuring that two pumps with reliable engines were supplied to prevent the likeliness of downtime.

Castle Pumps' specialist knowledge means that they often need to advise customers on what type of pump they need. For example, in this case study, the customer thought that they required a submersible pump, however due to the temperature of the fluid being pumped, Castle Pumps recognised that a vertical immersion pump was a better solution.
