New chopper pump achieves excessive efficiency with out compromising on cutting performance

Problematic solids such as sanitary towels, plastic luggage, textiles and wooden are being found more and more often in wastewater. Pumping and sewage treatment plants are subsequently increasingly reaching their limits; models get clogged up and break down.
In times when low lifecycle costs are playing an ever more necessary role, HOMA Pumpenfabrik presents an energy environment friendly and reliable answer for areas the place a high delivery head is required, but at the similar time, a diverse vary of solids is expected: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator collection enables efficient operation via a powerful cutter system. Thanks to using highly durable chilled chrome cast iron, the principle components that are subject to probably the most stress perform reliably even with abrasive substances corresponding to sand. HOMA shall be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle prices have gotten increasingly necessary in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for power saving and reliable pumps that reach high supply heads with great efficiency.” With เกจวัดแรงดันน้ำ4หุน , which may also be available as an explosion-proof version, HOMA has developed a very environment friendly response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our aim was to achieve high supply pressures within the medium circulate rate range,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and extra power saving motor than in different pumps in the same operating range was sufficient. To obtain this, HOMA developed a new cutter system that effectively shreds and removes massive quantities of various solids corresponding to tear-resistant hygiene wipes, plastic bags and wood, which additionally get into the wastewater by way of surface water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear plate, which can additionally be outfitted with its own cutter. This design permits the 2 central elements to work together to catch solids, break them down and ultimately take away them from the suction area by way of built-in grooves in the put on plate.
To allow greater effectivity without compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a outcome, within the 50 Hz model, a flow price of up to 130 m³/h and a delivery head of up to 57 m can be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of 8 to twenty kW, a circulate price of up to a hundred and forty m³/h and a supply head of up to eighty two m are possible. The suction cowl mounted on the pump housing can additionally be used to adjust the cutting gap between the impeller and the put on and tear plate with the assist of six set screws. “The strength of our new Alligator series, which is available for moist properly installation as nicely as dry installation, is its great effectivity and efficient cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to achieve not only the absolute best effectivity values within the working vary required for these sorts of wastewater applications, but also to scale back lifecycle costs general, HOMA attaches nice significance to low-maintenance operation in addition to effectivity. เกจ์ออกซิเจนsumo and put on plate, which are the elements subject to probably the most stress, are manufactured from extremely durable chilled chrome forged iron, which withstands even abrasive substances similar to sand in the pumped medium. In addition, the hydraulics had been optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to increase efficiency and to eliminate any possibility of solids building up, which can negatively influence efficiency and result in costly pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids within the waste water and transport them away, saving each power and maintenance prices thanks to their excessive efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water purposes that require high supply pressure, but at the similar time have to deal with many alternative kinds of solids.”
HOMA might be presenting the model new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and other improvements, corresponding to the upkeep slide with sliding motor mount, shall be explained and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
