New chopper pump achieves excessive effectivity with out compromising on chopping efficiency

Problematic solids corresponding to sanitary towels, plastic bags, textiles and wood are being discovered increasingly typically in wastewater. Pumping and sewage therapy plants are subsequently more and more reaching their limits; units get clogged up and break down.
In occasions when low lifecycle prices are enjoying an ever extra important function, HOMA Pumpenfabrik presents an vitality efficient and reliable resolution for areas where a high supply head is required, but on the similar time, a various range of solids is predicted: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection enables effective operation through a robust cutter system. Thanks to the usage of highly sturdy chilled chrome cast iron, the primary parts that are topic to the most stress perform reliably even with abrasive substances such as sand. HOMA will be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs are becoming more and more essential in water and wastewater functions,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for power saving and dependable pumps that attain high delivery heads with nice effectivity.” With its new Alligator chopper pump sequence, which may even be available as an explosion-proof version, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our goal was to realize excessive delivery pressures in the medium circulate price range,” stories Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and more power saving motor than in other pumps in the identical operating vary was adequate. To obtain this, HOMA developed a brand new cutter system that effectively shreds and removes large portions of various solids such as tear-resistant hygiene wipes, plastic bags and wood, which also get into the wastewater via surface water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which is also equipped with its own cutter. This design allows the two central elements to work together to catch solids, break them down and in the end remove them from the suction area through built-in grooves within the put on plate.
To enable higher effectivity with out compromising on cutting performance, the blades of the impeller also curve strongly backwards. As a result, in the 50 Hz version, a flow fee of as much as a hundred thirty m³/h and a delivery head of as a lot as fifty seven m could be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of eight to twenty kW, a move rate of as a lot as 140 m³/h and a supply head of as a lot as eighty two m are potential. The suction cowl mounted on the pump housing may additionally 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 out there for wet well set up in addition to dry installation, is its nice effectivity and efficient cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to realize not only the very best efficiency values within the working vary required for these sorts of wastewater purposes, but also to minimize back lifecycle costs general, HOMA attaches great importance to low-maintenance operation in addition to efficiency. Moneyback and put on plate, that are the parts topic to the most stress, are manufactured from extraordinarily durable chilled chrome cast iron, which withstands even abrasive substances corresponding to sand within the pumped medium. In addition, the hydraulics had been optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to increase effectivity and to eliminate any possibility of solids increase, which can negatively influence performance and lead to 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 vitality and maintenance costs thanks to their excessive effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water applications that require high delivery pressure, but at the identical time need to take care of many alternative 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 innovations, corresponding to the maintenance slide with sliding motor mount, might be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
