The ABS flow booster XSB reportedly saves 25% energy through its use of an improved efficiency motor and gearbox and a new design that boosts mixer efficiency. The 3-stage helical gearbox has a new strong oil-lubricated bearing configuration with a calculated lifetime of more than 100 000 h. The fatigue strength helical gears allow numerous reduction ratios and were specially developed for this mixer. The mixer also includes a Di moisture probe to continuously monitor the presence of any moisture ingress through the seal. Should this happen an inspection alert is signalled. The mixers have a maximum thrust of more than 6400 N. They have a patented mounting pedestal which can stabilise mixer operation. The blades can be separated easily from the hub, improving mixer transport, installation and maintenance. The launch of the ABS flow booster XSB and the ABS pump controller PC 441 represents the third part of the company’s “ABS EffeX Revolution” following the introduction of the ABS EffeX range of submersible sewage pumps, and the ABS submersible mixer XRW. The “ABS EffeX Revolution” involves developing technology to reduce energy consumption and increase equipment efficiency and reliability for the wastewater industry.
