Firstly we can observe the changing characteristics of wastewater, driven mainly by the reduction in water consumption and changes to personal hygiene habits. Have we seen the end of this change? No, the general feeling is that water consumption will continue to reduce with the consequent increase in rag content.
We can also see legislation and other incentives push all users of energy-using products (EuP) to install higher-efficiency and explosion-proof units. There is already legislation in place controlling circulator pumps with others to follow, including submersible pumps.
The ABS submersible sewage pumps XFP range looks to the future; it already more than complies with any legislation under discussion with regard to motor efficiency, hydraulic or total efficiency. With regard to rag handling, the new optimised impeller designs take into account reduced water consumption and increased rag content. The levels of reliability are again in excess of the requirements of global legislation controlling the standard of wastewater collection networks.
