New chopper pump achieves excessive efficiency without compromising on slicing performance

Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wooden are being found more and more usually in wastewater. Pumping and sewage treatment crops are due to this fact more and more reaching their limits; items get clogged up and break down.
In instances when low lifecycle prices are enjoying an ever more essential position, HOMA Pumpenfabrik presents an energy environment friendly and reliable solution for areas where a excessive supply head is required, however on the similar time, a various range of solids is anticipated: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator collection allows efficient operation via a robust cutter system. Thanks to the utilization of highly durable chilled chrome cast iron, the main components that are topic to the most stress perform reliably even with abrasive substances corresponding to sand. HOMA might be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs have gotten more and more necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for vitality saving and dependable pumps that reach high supply heads with great efficiency.” With its new Alligator chopper pump series, which may even be out there as an explosion-proof model, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with high efficiency
“Our objective was to attain high supply pressures within the medium circulate rate vary,” reports Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and extra power saving motor than in different pumps in the same working vary was sufficient. To achieve this, HOMA developed a model new cutter system that effectively shreds and removes giant portions of diverse solids corresponding to tear-resistant hygiene wipes, plastic luggage and wood, which also get into the wastewater through surface water. The specially designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which is also equipped with its personal cutter. This design permits the 2 central elements to work together to catch solids, break them down and ultimately remove them from the suction space by way of built-in grooves in the wear plate.
To enable larger effectivity without compromising on slicing performance, the blades of the impeller also curve strongly backwards. As a result, within the 50 Hz model, a circulate fee of as a lot as a hundred thirty m³/h and a supply head of as a lot as fifty seven m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of 8 to 20 kW, a circulate price of as a lot as a hundred and forty m³/h and a supply head of as much as 82 m are potential. The suction cover mounted on the pump housing can be used to adjust the cutting gap between the impeller and the wear and tear plate with the help of six set screws. “The strength of our new Alligator sequence, which is available for wet nicely set up in addition to dry set up, is its great effectivity and effective cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design
In order to realize not solely the best possible effectivity values in the operating range required for these sorts of wastewater applications, but also to reduce lifecycle costs general, HOMA attaches nice importance to low-maintenance operation along with effectivity. The impeller and wear plate, that are the components topic to essentially the most stress, are made of extremely durable chilled chrome cast iron, which withstands even abrasive substances such as sand within the pumped medium. In เกจวัดแรงดัน1บาร์ , the hydraulics have been optimally designed for the working range using computational fluid dynamics (CFD) to increase effectivity and to eliminate any chance of solids building up, which may negatively impact performance and result in costly 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 energy and upkeep prices because of their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water purposes that require high delivery pressure, but on the identical time have to take care of many different kinds of solids.”
HOMA shall be presenting the new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and other improvements, such as the upkeep slide with sliding motor mount, might be explained and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
