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

Problematic solids corresponding to sanitary towels, plastic luggage, textiles and wooden are being discovered increasingly usually in wastewater. Pumping and sewage therapy vegetation are therefore increasingly reaching their limits; models get clogged up and break down.
In times when low lifecycle costs are enjoying an ever more necessary role, HOMA Pumpenfabrik provides an vitality environment friendly and reliable resolution for areas the place a excessive supply head is required, however on the identical time, a various vary of solids is anticipated: the Alligator chopper pump series. The newly developed OC impeller of the Alligator sequence allows effective operation via a robust cutter system. Thanks to using highly sturdy chilled chrome cast iron, the principle parts which might be subject to the most stress perform reliably even with abrasive substances such as sand. HOMA will be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle prices have gotten more and more necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for energy saving and reliable pumps that attain high supply heads with nice effectivity.” With its new Alligator chopper pump collection, which may also be out there as an explosion-proof version, HOMA has developed a very efficient response to this demand.

“Our goal was to attain high supply pressures within the medium circulate rate range,” reports Konstantin Pörsch. Without forfeiting pump rate, the improved effectivity meant that a smaller, cheaper and more vitality saving motor than in different pumps in the identical operating vary was adequate. To obtain this, HOMA developed a model new cutter system that effectively shreds and removes large quantities of diverse solids such as tear-resistant hygiene wipes, plastic bags and wooden, which also get into the wastewater via surface water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the put on and tear plate, which can be outfitted with its own cutter. This design allows the two central components to work together to catch solids, break them down and finally take away them from the suction area through integrated grooves within the wear plate.
To allow higher effectivity without compromising on cutting performance, the blades of the impeller additionally curve strongly backwards. As a end result, in the 50 Hz model, a circulate price of up to 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 version, with power consumption of 8 to 20 kW, a move price of up to 140 m³/h and a delivery head of as a lot as eighty two m are possible. The suction cover mounted on the pump housing may additionally be used to adjust the cutting hole between the impeller and the wear plate with the help of six set screws. “The power of our new Alligator sequence, which is on the market for wet well set up in addition to dry set up, is its nice effectivity and efficient cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design

In order to realize not only the very best efficiency values within the working range required for these kinds of wastewater applications, but also to cut back lifecycle prices general, HOMA attaches nice significance to low-maintenance operation in addition to efficiency. The impeller and put on plate, which are the parts subject to the most stress, are made of extraordinarily sturdy 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 increase effectivity and to remove any chance of solids building up, which might negatively impression performance and lead to 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 each vitality and maintenance prices because of their high efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water functions that require high delivery strain, but at the same time need to take care of many different kinds 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 maintenance slide with sliding motor mount, shall be defined and demonstrated by the HOMA sales group in Hall B1 at Stand 429/528.
