New chopper pump achieves excessive efficiency with out compromising on cutting performance

Problematic solids corresponding to sanitary towels, plastic luggage, textiles and wooden are being found increasingly often in wastewater. Pumping and sewage treatment vegetation are due to this fact increasingly reaching their limits; models get clogged up and break down.
In occasions when low lifecycle prices are taking part in an ever more necessary role, HOMA Pumpenfabrik provides an power efficient and dependable resolution for areas where a excessive delivery head is required, but on the identical time, a diverse range of solids is predicted: the Alligator chopper pump sequence. เกจวัดแรงดันnuovafima developed OC impeller of the Alligator collection enables efficient operation by way of a robust cutter system. Thanks to the use of highly sturdy chilled chrome cast iron, the principle elements which are topic to the most stress perform reliably even with abrasive substances such as sand. HOMA shall be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle prices have gotten more and more important in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and dependable pumps that attain excessive supply heads with great effectivity.” With its new Alligator chopper pump collection, which may even be out there as an explosion-proof version, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with high efficiency
“Our objective was to achieve excessive supply pressures in the medium move rate vary,” reports Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and extra vitality saving motor than in other pumps in the same operating range was enough. To obtain this, HOMA developed a brand new cutter system that successfully shreds and removes large portions of numerous solids similar to tear-resistant hygiene wipes, plastic luggage and wooden, which also get into the wastewater through floor water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the put on and tear plate, which can be equipped with its own cutter. This design permits the 2 central parts to work together to catch solids, break them down and finally remove them from the suction space via integrated grooves in the put on plate.
To enable greater efficiency with out compromising on chopping efficiency, the blades of the impeller additionally curve strongly backwards. As a end result, in the 50 Hz model, a move rate of as much as one hundred thirty m³/h and a delivery head of as much as 57 m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of 8 to 20 kW, a move rate of as much as one hundred forty m³/h and a supply head of up to eighty two m are attainable. The suction cowl mounted on the pump housing can be used to adjust the chopping hole between the impeller and the damage plate with assistance from six set screws. “The power of our new Alligator series, which is out there for wet properly installation in addition to dry installation, is its nice effectivity and efficient cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle costs thanks to wear-resistant design
In order to achieve not solely the very best efficiency values in the operating range required for these kinds of wastewater applications, but additionally to reduce back lifecycle prices overall, HOMA attaches great importance to low-maintenance operation in addition to efficiency. The impeller and put on plate, that are the components subject to the most stress, are made of extraordinarily sturdy chilled chrome cast iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics have been optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to increase efficiency and to remove any risk of solids increase, which might negatively influence efficiency and lead to costly 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 upkeep costs thanks to their high efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water functions that require excessive supply stress, however at the identical time have to cope with many different sorts of solids.”
HOMA will be presenting the new Alligator chopper pump series for the primary time at IFAT 2022 in Munich. This and different innovations, such as the upkeep slide with sliding motor mount, will be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
