A refreshing sip of cold water at the turn of a tap: nothing but a dream for many. “2.2 billion people worldwide currently have no access to clean and safe drinking water. Around half a billion of them live in Africa. These people live under the constant danger or catching life-threatening diseases, which in the worst case can develop into epidemics,” says Heinz Lutz, CEO of Lutz Holding. “In view of these alarming figures, it is clear that the international community must act to provide universal access to clean drinking water.” Seeking to play its part, Lutz-Jesco has developed new technologies that support efficient water treatment, and which were on display at the Water Africa 2024 trade fair.
MEMDOS SMART: A DOSING PUMP WITH INTUITIVE OPERATION
Exhibiting at this year’s Water Africa trade fair, Lutz-Jesco showcased its Memdos Smart, a stepper motor dosing pump that helps to improve water quality in small wastewater treatment plants and waterworks. The pump performs a number of functions, including the introduction of flocculants into the water. These agents serve to combine impurities and suspended matter into larger particles which are easier to separate.
“Precise dosing is crucial for high quality water treatment,” says Steffen Roth, head of development at Lutz-Jesco GmbH. “To this end, we have fitted the Memdos Smart with a microprocessor-controlled stepper motor.”
Its special feature: unlike standard motors, the motor of the diaphragm pump can be run asynchronously. It works at higher speed during priming so that it draws in the liquid more quickly with stronger negative pressure, whilst working at a lower speed during controlled and even discharge. “Thanks to the stepper motor, we are able to achieve an almost constant supply stream, which enables gentle, low-pulsation and precise dosing of chemicals for water treatment in small wastewater treatment plants and waterworks.”
The Memdos Smart is available in eight performance levels—with supply streams between 0.5 and 50 gallons per hour.
And is also intuitive to operate. Roth says, “The combination of a full-colour touch display with operation similar to a smartphone sets us apart from other market players. Users can understand and perform all functions immediately without the need for operating instructions. This makes control of the pumps significantly quicker and less prone to malfunctions.”
BATTERY-POWERED FOR AREAS WITH A POOR INFRASTRUCTURE
The B3 Battery is a new battery-powered drum pump that combines mobility and energy independence for water and wastewater management in remote areas with poor infrastructure. Fitted with a brushless 320-watt DC motor, it offers a delivery capacity of up to 50 gallons per minute and a delivery head of 39 feet of water column.
“With the new B3 Battery, we have succeeded for the first time in making the performance of a battery-operated drum pump comparable to that of cable-connected models,” says Michael Raabe, head of sales at Lutz Jesco GmbH. One battery charge is enough to empty a 50-gallon drum fourteen times in around fifteen minutes. At a lower speed, a 250-plus gallon IBC container can be pumped out 5.8 times in fifty-one minutes. The pumping station is available in different versions to convey as many chemicals as possible for water treatment, including a version made of polypropylene (PP) for sodium hydroxide and of polyvinylidene fluoride (PVDF) for chloric acid.
Established in 1954, the internationally active family business Lutz has advanced to become synonymous for professional fluid management. Today, the Lutz group of companies includes a number of top-performing, medium-sized companies located in Germany and abroad, which operate in the broad field of pump technology, water treatment and disinfection. The Lutz Group has thirteen branch offices and representatives in over eighty countries. For more information, visit www.lutzjescoamerica.com.
