New chopper pump achieves excessive efficiency without compromising on slicing performance
Problematic solids such as sanitary towels, plastic baggage, textiles and wood are being found increasingly more usually in wastewater. Pumping and sewage therapy crops are therefore more and more reaching their limits; models get clogged up and break down.
In times when low lifecycle costs are playing an ever more necessary position, HOMA Pumpenfabrik offers an energy efficient and reliable solution for areas where a excessive delivery head is required, however on the identical time, a diverse vary of solids is predicted: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator sequence allows effective operation by way of a robust cutter system. เพรสเชอร์เกจคือ to the use of extremely durable chilled chrome forged iron, the primary components that are subject to probably the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA shall be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle prices have gotten increasingly necessary in water and wastewater functions,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for power saving and dependable pumps that reach high delivery heads with nice effectivity.” With its new Alligator chopper pump series, which may also be out there as an explosion-proof model, HOMA has developed a very efficient response to this demand.

“Our goal was to realize high delivery pressures in the medium flow fee range,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and more power saving motor than in different pumps in the same working vary was enough. To achieve this, HOMA developed a brand new cutter system that effectively shreds and removes giant quantities of diverse solids similar to tear-resistant hygiene wipes, plastic bags and wood, which also get into the wastewater via floor 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 two central parts to work together to catch solids, break them down and in the end take away them from the suction space through built-in grooves in the wear plate.
To allow higher effectivity without compromising on slicing performance, the blades of the impeller also curve strongly backwards. As a end result, in the 50 Hz version, a flow rate of up to 130 m³/h and a supply head of up to fifty seven m can be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of eight to 20 kW, a move rate of up to 140 m³/h and a delivery head of up to 82 m are attainable. The suction cover mounted on the pump housing can also be used to regulate the chopping hole between the impeller and the damage plate with assistance from six set screws. “The energy of our new Alligator collection, which is out there for moist nicely set up as properly as dry installation, is its nice effectivity and efficient cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design

In order to attain not solely the very best effectivity values within the working range required for these kinds of wastewater functions, but in addition to scale back lifecycle costs overall, HOMA attaches great importance to low-maintenance operation in addition to efficiency. The impeller and wear plate, that are the components subject to essentially the most stress, are made from extremely sturdy 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 operating vary using computational fluid dynamics (CFD) to extend effectivity and to remove any possibility of solids build up, which might negatively impact performance 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 each power and maintenance prices thanks to their high efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably appropriate for waste water functions that require high supply stress, but at the same time have to deal with many different sorts of solids.”

HOMA shall be presenting the brand new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and different improvements, such as the upkeep slide with sliding motor mount, will be defined and demonstrated by the HOMA gross sales group in Hall B1 at Stand 429/528.
