New chopper pump achieves excessive efficiency without compromising on cutting efficiency

Problematic solids similar to sanitary towels, plastic luggage, textiles and wood are being discovered more and more often in wastewater. Pumping and sewage therapy plants are due to this fact more and more reaching their limits; items get clogged up and break down.
In instances when low lifecycle costs are taking half in an ever more necessary role, HOMA Pumpenfabrik offers an vitality environment friendly and dependable resolution for areas where a high delivery head is required, but at the same time, a diverse vary of solids is expected: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection allows effective operation via a strong cutter system. Thanks to the utilization of highly sturdy chilled chrome cast iron, the primary parts which would possibly be topic to probably the most stress carry out reliably even with abrasive substances such as sand. HOMA will be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs have gotten increasingly important in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for power saving and reliable pumps that reach high delivery heads with great efficiency.” With its new Alligator chopper pump collection, which may even be available as an explosion-proof model, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with high efficiency
“Our aim was to realize excessive supply pressures in the medium flow fee vary,” reviews Konstantin Pörsch. Without forfeiting เกจ์แรงดัน , 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 successfully shreds and removes massive quantities of numerous solids similar to tear-resistant hygiene wipes, plastic luggage 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 wear and tear plate, which can be outfitted with its personal cutter. This design permits the 2 central parts to work collectively to catch solids, break them down and ultimately remove them from the suction area through built-in grooves within the put on plate.
To enable เกจวัดแรงดันไนโตรเจน without compromising on chopping efficiency, the blades of the impeller also curve strongly backwards. As a outcome, in the 50 Hz model, a flow rate of up to a hundred thirty m³/h and a supply head of up to 57 m could be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of 8 to 20 kW, a circulate price of up to a hundred and forty m³/h and a delivery head of up to eighty two m are potential. The suction cover mounted on the pump housing can additionally be used to regulate the chopping gap between the impeller and the damage plate with assistance from six set screws. “The strength of our new Alligator collection, which is available for wet properly set up in addition to dry set up, is its great efficiency and efficient cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to achieve not only the finest possible efficiency values in the operating range required for these sorts of wastewater applications, but additionally to cut back lifecycle costs overall, HOMA attaches great importance to low-maintenance operation in addition to efficiency. The impeller and put on plate, that are the elements subject to essentially the most stress, are made from extraordinarily durable chilled chrome forged iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics were optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to increase efficiency and to eliminate any risk of solids build up, which might negatively influence performance and result in expensive 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 costs thanks to their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water purposes that require high delivery strain, but on the same time should cope with many various sorts of solids.”
HOMA shall be presenting the brand new Alligator chopper pump collection for the primary time at IFAT 2022 in Munich. This and different innovations, similar 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.
