New chopper pump achieves high efficiency with out compromising on chopping performance

Problematic solids similar to sanitary towels, plastic bags, textiles and wood are being discovered increasingly more often in wastewater. Pumping and เกจวัดแรงดันแก๊สหุงต้ม are subsequently increasingly reaching their limits; units get clogged up and break down.
In instances when low lifecycle prices are playing an ever more important role, HOMA Pumpenfabrik presents an power efficient and dependable solution for areas the place a excessive delivery head is required, however at the similar time, a diverse range of solids is expected: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection allows efficient operation via a robust cutter system. Thanks to using highly durable chilled chrome forged iron, the principle parts that are topic to probably the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA will be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs have gotten more and more essential in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for vitality saving and dependable pumps that attain high delivery heads with great effectivity.” With its new Alligator chopper pump sequence, 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 excessive effectivity
“Our goal was to realize high delivery pressures in the medium move rate vary,” stories Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and extra energy saving motor than in other pumps in the same operating range was enough. To obtain this, HOMA developed a model new cutter system that effectively shreds and removes large quantities of numerous solids corresponding to tear-resistant hygiene wipes, plastic luggage and wood, which additionally 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 and tear plate, which can be geared up with its personal cutter. This design allows the two central elements to work together to catch solids, break them down and finally remove them from the suction space via integrated grooves in the put on plate.
To allow greater effectivity without compromising on cutting efficiency, the blades of the impeller also 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 could be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of 8 to twenty kW, a circulate rate of as much as 140 m³/h and a delivery head of up to eighty two m are attainable. The suction cover mounted on the pump housing can also be used to adjust the cutting gap between the impeller and the damage plate with the assist of six set screws. “The strength of our new Alligator series, which is available for moist nicely installation as nicely as dry set up, is its great effectivity and effective cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
Low lifecycle costs thanks to wear-resistant design
In order to achieve not only the absolute best effectivity values in the working range required for these sorts of wastewater purposes, but also to cut back lifecycle costs general, HOMA attaches nice importance to low-maintenance operation in addition to efficiency. The impeller and wear plate, which are the elements subject to essentially the most stress, are made from extraordinarily sturdy chilled chrome cast iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics have been optimally designed for the working vary utilizing computational fluid dynamics (CFD) to extend efficiency and to get rid of any possibility of solids build up, which might negatively impact performance and lead to expensive 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 each vitality and maintenance prices because of their high efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water functions that require high supply pressure, however on the same time need to take care of many various sorts of solids.”
HOMA shall be presenting the new Alligator chopper pump collection for the primary time at IFAT 2022 in Munich. This and different innovations, such as the maintenance slide with sliding motor mount, will be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
