New chopper pump achieves high effectivity without compromising on chopping performance

Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wood are being found increasingly more usually in wastewater. Pumping and sewage therapy vegetation are therefore more and more reaching their limits; units get clogged up and break down.
In times when low lifecycle prices are enjoying an ever more essential position, HOMA Pumpenfabrik offers an energy efficient and reliable solution for areas where a high delivery head is required, but on the same time, a various vary of solids is predicted: the Alligator chopper pump series. The newly developed OC impeller of the Alligator sequence permits effective operation via a powerful cutter system. Thanks to using highly sturdy chilled chrome cast iron, the primary components which may be topic to probably the most stress carry out reliably even with abrasive substances similar to sand. HOMA might be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle prices are becoming increasingly important in water and wastewater functions,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for vitality saving and reliable pumps that reach high supply heads with great efficiency.” With its new Alligator chopper pump series, which may also be out there as an explosion-proof version, HOMA has developed a very environment friendly response to this demand.
เพรสเชอร์เกจ with high effectivity

“Our aim was to achieve high supply pressures in the medium move fee range,” stories Konstantin Pörsch. Without forfeiting pump fee, the improved efficiency meant that a smaller, cheaper and extra energy saving motor than in other pumps in the same operating vary was sufficient. To achieve this, HOMA developed a brand new cutter system that effectively shreds and removes giant portions of various solids such as tear-resistant hygiene wipes, plastic luggage and wooden, which also get into the wastewater through surface water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear plate, which can be equipped with its own cutter. This design allows the two central elements to work collectively to catch solids, break them down and in the end remove them from the suction area through integrated grooves in the put on plate.
To allow greater efficiency without compromising on slicing efficiency, the blades of the impeller also curve strongly backwards. As a outcome, within the 50 Hz version, a move fee of as much as 130 m³/h and a delivery head of up to 57 m can be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of eight to twenty kW, a circulate fee of as a lot as one hundred forty m³/h and a delivery head of up to eighty two m are potential. The suction cover mounted on the pump housing can be used to adjust the chopping hole between the impeller and the damage plate with the help of six set screws. “The power of our new Alligator collection, which is available for wet properly set up as well as dry set up, is its nice efficiency and efficient cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle costs because of wear-resistant design

In order to attain not solely the finest possible efficiency values within the operating vary required for these kinds of wastewater purposes, but in addition to reduce lifecycle costs overall, HOMA attaches great significance to low-maintenance operation in addition to effectivity. The impeller and put on plate, that are the elements topic to probably the most stress, are manufactured from extremely durable chilled chrome forged iron, which withstands even abrasive substances similar to sand in 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 get rid of any possibility of solids build up, which can negatively impact efficiency and lead to 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 maintenance costs thanks to their high efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them notably appropriate for waste water functions that require excessive supply pressure, but at the same time should cope with many alternative sorts of solids.”

HOMA might be presenting the brand new Alligator chopper pump collection for the first time at IFAT 2022 in Munich. This and other improvements, corresponding to the upkeep slide with sliding motor mount, shall be defined and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
