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

Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wood are being discovered more and more usually in wastewater. Pumping and sewage treatment crops are therefore more and more reaching their limits; models get clogged up and break down.
In instances when low lifecycle prices are playing an ever more necessary position, HOMA Pumpenfabrik presents an vitality environment friendly and dependable resolution for areas where a excessive delivery head is required, however on the similar time, a diverse vary of solids is expected: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator sequence enables efficient operation through a robust cutter system. Thanks to using highly sturdy chilled chrome forged iron, the main components that are topic to the most stress carry out reliably even with abrasive substances such as sand. HOMA might be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle prices have gotten increasingly essential in water and wastewater applications,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for power saving and reliable pumps that reach high delivery heads with nice efficiency.” 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.
Cutter system shreds all solids with high effectivity
“Our aim was to realize high supply pressures within the medium flow fee vary,” reviews Konstantin Pörsch. Without forfeiting pump rate, the improved effectivity meant that a smaller, cheaper and more energy saving motor than in different pumps in the same working vary was adequate. To achieve this, HOMA developed a new cutter system that effectively shreds and removes giant portions of numerous solids corresponding to tear-resistant hygiene wipes, plastic luggage and wood, which additionally get into the wastewater via surface water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the wear plate, which can also be equipped with its own cutter. This design permits the two central elements to work together to catch solids, break them down and finally take away them from the suction space through integrated grooves within the put on plate.
To enable Manageable with out compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a end result, within the 50 Hz model, a move rate of as a lot as a hundred thirty m³/h and a delivery head of up to fifty seven m could 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 price of up to one hundred forty m³/h and a supply head of as much as eighty two m are potential. The suction cover mounted on the pump housing may also be used to regulate the chopping hole between the impeller and the damage plate with the aid of six set screws. “The strength of our new Alligator sequence, which is on the market for moist properly installation as properly as dry set up, is its great effectivity and efficient cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle prices due to wear-resistant design
In order to attain not only the absolute best effectivity values within the working range required for these sorts of wastewater functions, but in addition to scale back lifecycle prices general, HOMA attaches great importance to low-maintenance operation in addition to effectivity. The impeller and wear plate, that are the parts subject to essentially the most stress, are manufactured from extremely durable chilled chrome forged iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics were optimally designed for the operating vary using computational fluid dynamics (CFD) to increase effectivity and to eliminate any possibility of solids increase, which may negatively impression performance and result in expensive pump failures. “With the newly developed cutter system, the Alligator pumps can successfully break down all solids within the waste water and transport them away, saving both energy and upkeep costs because of their high effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “ Fail-proof makes them particularly appropriate for waste water purposes that require excessive supply stress, but on the identical time should take care of many alternative kinds of solids.”
HOMA will be presenting the new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and other improvements, similar to the maintenance slide with sliding motor mount, shall be explained and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
