New chopper pump achieves high effectivity without compromising on chopping efficiency

Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wooden are being found increasingly more typically in wastewater. Pumping and sewage therapy vegetation are subsequently increasingly reaching their limits; units get clogged up and break down.
In occasions when low lifecycle prices are taking part in an ever extra essential function, HOMA Pumpenfabrik presents an energy environment friendly and dependable resolution for areas where a high supply head is required, but at the similar time, a various vary of solids is expected: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator collection allows effective operation via a powerful cutter system. Thanks to the utilization of highly durable chilled chrome cast iron, the primary components that are topic to probably the most stress perform reliably even with abrasive substances similar to sand. HOMA might be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs have gotten more and more necessary in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and reliable pumps that attain high delivery heads with nice effectivity.” With its new Alligator chopper pump sequence, which will also be obtainable as an explosion-proof version, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with high effectivity
“Our goal was to attain excessive delivery pressures in the medium move fee range,” reviews Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and more vitality saving motor than in other pumps in the same working range was sufficient. To obtain this, HOMA developed a model new cutter system that effectively shreds and removes massive quantities of diverse solids such as tear-resistant hygiene wipes, plastic bags and wood, which also get into the wastewater via floor water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which can additionally be geared up with its personal cutter. เกจ์วัดแรงดัน allows the 2 central components to work together to catch solids, break them down and finally take away them from the suction area via built-in grooves within the wear plate.
To allow greater effectivity without compromising on chopping efficiency, the blades of the impeller additionally curve strongly backwards. As a outcome, within the 50 Hz model, a circulate price of as much as 130 m³/h and a supply head of up to 57 m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of eight to twenty kW, a circulate fee of up to one hundred forty m³/h and a supply head of up to 82 m are possible. The suction cover mounted on the pump housing can be used to adjust the chopping hole between the impeller and the wear plate with the assist of six set screws. “The power of our new Alligator sequence, which is available for moist well set up in addition to dry installation, is its great effectivity and efficient cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design
In order to realize not only the absolute best efficiency values within the working vary required for these kinds of wastewater functions, but additionally to reduce back lifecycle prices overall, HOMA attaches nice importance to low-maintenance operation in addition to effectivity. The impeller and put on plate, which are the parts subject to the most stress, are made of extremely durable chilled chrome cast iron, which withstands even abrasive substances similar to sand within the pumped medium. In addition, the hydraulics were optimally designed for the working vary using computational fluid dynamics (CFD) to increase efficiency and to eliminate any risk of solids building up, which may negatively influence performance and result in expensive pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids in the waste water and transport them away, saving both vitality and maintenance prices because of their high effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water purposes that require high delivery stress, but at the identical time should deal with many various kinds of solids.”
HOMA might be presenting the new Alligator chopper pump collection for the first time at IFAT 2022 in Munich. This and other improvements, such as the maintenance slide with sliding motor mount, shall be defined and demonstrated by the HOMA gross sales group in Hall B1 at Stand 429/528.
