New chopper pump achieves high effectivity with out compromising on slicing efficiency

Problematic solids such as sanitary towels, plastic luggage, textiles and wooden are being discovered increasingly more often in wastewater. Pumping and sewage remedy vegetation are due to this fact more and more reaching their limits; units get clogged up and break down.
In instances when low lifecycle costs are playing an ever extra necessary role, HOMA Pumpenfabrik presents an vitality efficient and reliable answer for areas where a excessive delivery head is required, but on the similar time, a various vary of solids is expected: the Alligator chopper pump series. เกจวัดแรงดันน้ำดิจิตอล developed OC impeller of the Alligator collection enables efficient operation through a powerful cutter system. Thanks to using highly durable chilled chrome forged iron, the main parts that are subject to probably the most stress carry out reliably even with abrasive substances similar to sand. HOMA shall be presenting the model new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs are becoming increasingly essential in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for power saving and dependable pumps that reach excessive supply heads with great efficiency.” With its new Alligator chopper pump sequence, which may also be obtainable as an explosion-proof model, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our aim was to attain excessive supply pressures in the medium circulate fee range,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and extra energy saving motor than in other pumps in the same working vary was enough. To achieve this, HOMA developed a model new cutter system that successfully shreds and removes massive portions of numerous solids similar to tear-resistant hygiene wipes, plastic bags and wood, which additionally get into the wastewater via floor water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which can also be outfitted with its own cutter. This design allows the 2 central components to work together to catch solids, break them down and finally take away them from the suction area through built-in grooves within the wear plate.
To allow greater effectivity with out compromising on chopping performance, the blades of the impeller also curve strongly backwards. As a outcome, in the 50 Hz version, a move price of as much as one hundred thirty m³/h and a delivery head of up to fifty seven m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of eight to 20 kW, a flow rate of up to a hundred and forty m³/h and a supply head of as a lot as eighty two m are potential. The suction cowl mounted on the pump housing can also be used to regulate the slicing gap between the impeller and the wear plate with the help of six set screws. “The power of our new Alligator series, which is on the market for moist well set up in addition to dry installation, is its nice effectivity and efficient cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle prices due to wear-resistant design
In order to attain not only the finest possible efficiency values within the operating vary required for these kinds of wastewater functions, but additionally to minimize back lifecycle prices total, HOMA attaches nice significance to low-maintenance operation along with effectivity. The impeller and wear plate, which are the components subject to essentially the most stress, are made from extremely sturdy chilled chrome cast iron, which withstands even abrasive substances corresponding to sand within the pumped medium. In addition, the hydraulics have been optimally designed for the working vary utilizing computational fluid dynamics (CFD) to increase effectivity and to eliminate any chance of solids increase, which may negatively influence efficiency and lead to pricey 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 both vitality and maintenance costs because of their excessive effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water applications that require high supply stress, but at the same time have to cope with many different sorts of solids.”
HOMA shall be presenting the new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and different improvements, such as the maintenance slide with sliding motor mount, might be explained and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
