Chamber success as Borger’s pumps take screws out and send energy costs down
23/08/2023 Borger UK Ltd
Burdened with cumbersome maintenance, expensive spare parts and very high energy costs, a wastewater treatment plant has replaced its multi-phase eccentric screw pumps with new Rotary Lobe pumps, made by Börger.
Installed for a chamber filter press, the space-saving Börger pumps have been supplied as a twin-pack unit; two identical Rotary Lobe Pumps, which are operated in series. Each Börger rotary lobe pump has its own frequency converter that allows speeds to be individually regulated.
When feeding the chamber filter press, operators at the wastewater treatment plant now have a choice between two phases - the pre-fill phase and the pressurized phase. During the pre-fill phase, large quantities of sludge are pumped at high speed into the chamber filter press to fill up its chamber.
As the solids in the sludge gather in front of the filter screens, the increasing filling level of the chamber increases the counter pressure in the chamber filter press. Using the frequency converter, the speed of the Börger pumps is then reduced accordingly.
In addition to improving the output and efficiency of the application, the new Rotary Lobe pumps have drastically reduced energy costs, and are also far easier to service with their easy access, Maintenance-In-Place design.
