New chopper pump achieves high effectivity without compromising on slicing efficiency

Problematic solids similar to sanitary towels, plastic baggage, textiles and wood are being found increasingly more usually in wastewater. Pumping and sewage treatment crops are due to this fact more and more reaching their limits; units get clogged up and break down.
In times when low lifecycle prices are taking half in an ever more necessary position, HOMA Pumpenfabrik offers an vitality efficient and dependable answer for areas where a excessive delivery head is required, but at the same time, a various vary of solids is anticipated: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator sequence permits effective operation via a strong cutter system. Thanks to the use of extremely sturdy chilled chrome cast iron, the main components that are subject to probably the most stress perform reliably even with abrasive substances such as sand. HOMA might be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs are becoming more and more necessary in water and wastewater applications,” 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 reach high supply heads with great effectivity.” With its new Alligator chopper pump series, which will also 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 goal was to achieve high supply pressures in the medium circulate rate vary,” stories Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and extra power saving motor than in other pumps in the identical operating range was adequate. To obtain this, HOMA developed a brand new cutter system that effectively shreds and removes massive portions of diverse solids corresponding to tear-resistant hygiene wipes, plastic baggage and wood, which also get into the wastewater by way of floor water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear plate, which can also be outfitted with its personal cutter. This design allows the 2 central components to work collectively to catch solids, break them down and ultimately remove them from the suction area via built-in grooves in the put on plate.
To enable higher effectivity with out compromising on chopping performance, the blades of the impeller additionally curve strongly backwards. As a result, within the 50 Hz version, a circulate fee of up to a hundred thirty 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 version, with energy consumption of 8 to 20 kW, a circulate price of up to one hundred forty m³/h and a supply head of up to eighty two m are potential. The suction cover mounted on the pump housing may additionally be used to adjust the slicing gap between the impeller and the wear and tear plate with assistance from six set screws. “The energy of our new Alligator series, which is on the market for moist properly installation in addition to dry installation, is its nice effectivity and efficient cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle costs because of wear-resistant design
In order to attain not only the very best effectivity values in the operating vary required for these kinds of wastewater functions, but also to minimize back lifecycle prices overall, HOMA attaches great significance to low-maintenance operation along with efficiency. เพรสเชอร์เกจดิจิตอล and put on plate, which are the components topic to probably the most stress, are made from extremely sturdy chilled chrome forged iron, which withstands even abrasive substances similar to sand in the pumped medium. In addition, the hydraulics were optimally designed for the working vary utilizing computational fluid dynamics (CFD) to extend efficiency and to eliminate any possibility of solids building up, which may negatively impression performance and lead to costly pump failures. “With the newly developed cutter system, the Alligator pumps can successfully break down all solids within the waste water and transport them away, saving each vitality and upkeep prices due to their excessive effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water functions that require high supply stress, but at the identical time should deal with many alternative kinds of solids.”
HOMA will be presenting the brand new Alligator chopper pump series for the primary time at IFAT 2022 in Munich. This and different improvements, corresponding to the maintenance slide with sliding motor mount, might be defined and demonstrated by the HOMA gross sales staff in Hall B1 at Stand 429/528.
