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

Problematic solids similar to sanitary towels, plastic luggage, textiles and wood are being found more and more often in wastewater. Pumping and เพรสเชอร์เกจน้ำ are due to this fact more and more reaching their limits; units get clogged up and break down.
In occasions when low lifecycle costs are taking part in an ever more important function, HOMA Pumpenfabrik provides an energy environment friendly and dependable answer for areas where a high delivery head is required, but on the same time, a diverse vary of solids is anticipated: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator series enables efficient operation via a strong cutter system. Thanks to using highly sturdy chilled chrome forged iron, the main parts that are topic to the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA will be presenting เครื่องมือที่ใช้วัดความดัน for the first time at IFAT 2022 in Munich.
“The lowest potential lifecycle prices are becoming increasingly necessary in water and wastewater functions,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for vitality saving and reliable pumps that attain excessive supply heads with great effectivity.” With its new Alligator chopper pump sequence, which may even be out there as an explosion-proof model, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our objective was to achieve high delivery pressures in the medium move rate range,” stories Konstantin Pörsch. Without forfeiting pump fee, the improved efficiency meant that a smaller, cheaper and extra energy saving motor than in other pumps in the same operating vary was enough. To achieve this, HOMA developed a model new cutter system that effectively shreds and removes giant portions of various solids such as tear-resistant hygiene wipes, plastic bags and wooden, which also get into the wastewater through surface water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the wear plate, which can be outfitted with its personal cutter. This design allows the two central elements to work collectively to catch solids, break them down and finally take away them from the suction area through built-in grooves in the put on plate.
To allow higher efficiency with out compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a outcome, in the 50 Hz version, a flow fee of as a lot as one hundred thirty m³/h and a delivery head of up to 57 m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of 8 to 20 kW, a circulate rate of up to one hundred forty m³/h and a supply head of as a lot as eighty two m are attainable. The suction cowl mounted on the pump housing may also be used to regulate the slicing hole between the impeller and the wear plate with the help of six set screws. “The energy of our new Alligator sequence, which is on the market for moist properly installation in addition to dry set up, is its nice effectivity and efficient cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design
In order to achieve not solely the absolute best effectivity values in the operating vary required for these sorts of wastewater functions, but in addition to reduce lifecycle prices overall, HOMA attaches nice significance to low-maintenance operation in addition to effectivity. The impeller and put on plate, which are the components topic to probably the most stress, are made of extraordinarily durable chilled chrome cast iron, which withstands even abrasive substances such as sand within the pumped medium. In addition, the hydraulics have been optimally designed for the working vary utilizing computational fluid dynamics (CFD) to extend effectivity and to remove any chance of solids building up, which may negatively impression efficiency and result in pricey pump failures. “With the newly developed cutter system, the Alligator pumps can successfully break down all solids in the waste water and transport them away, saving both vitality and maintenance costs due to their excessive efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water purposes that require high delivery pressure, however at the same time have to take care of many alternative sorts of solids.”
HOMA shall be presenting the brand new Alligator chopper pump collection for the first time at IFAT 2022 in Munich. This and other improvements, such as the upkeep slide with sliding motor mount, will be defined and demonstrated by the HOMA sales group in Hall B1 at Stand 429/528.
