Problematic solids similar to sanitary towels, plastic luggage, textiles and wooden are being found 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 prices are enjoying an ever more necessary position, HOMA Pumpenfabrik presents an energy environment friendly and reliable solution for areas where a excessive supply head is required, however on the identical time, a various range of solids is expected: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection allows effective operation via a strong cutter system. Thanks to the usage of highly sturdy chilled chrome cast iron, the main elements that are topic to probably the most stress carry out reliably even with abrasive substances such as sand. HOMA shall be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs are becoming 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 power saving and reliable pumps that attain excessive delivery heads with nice effectivity.” With its new Alligator chopper pump sequence, which will also be available as an explosion-proof version, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our aim was to realize high supply pressures in the medium move rate vary,” reports Konstantin Pörsch. Without forfeiting pump rate, the improved effectivity meant that a smaller, cheaper and more power saving motor than in other pumps in the same working vary was enough. To obtain this, HOMA developed a model new cutter system that effectively shreds and removes giant portions of numerous solids such as tear-resistant hygiene wipes, plastic bags and wood, which additionally get into the wastewater by way of surface water. เกจวัดแรงดันต่ำ designed impeller has integrated 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 2 central elements to work together to catch solids, break them down and in the end take away them from the suction space via built-in grooves within the wear plate.
To allow larger efficiency without compromising on cutting efficiency, the blades of the impeller additionally curve strongly backwards. As a result, in the 50 Hz version, a circulate fee of up to one hundred thirty m³/h and a delivery head of as much as fifty seven m can be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of 8 to 20 kW, a move fee of as much as a hundred and forty m³/h and a supply head of as much as eighty two m are attainable. The suction cover mounted on the pump housing may additionally be used to regulate the chopping hole between the impeller and the wear plate with assistance from six set screws. “The power of our new Alligator series, which is out there for wet properly set up in addition to dry set up, is its great effectivity and effective cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design
In order to attain not only the very best effectivity values in the working vary required for these sorts of wastewater applications, but additionally to reduce back lifecycle costs total, HOMA attaches great importance to low-maintenance operation in addition to effectivity. The impeller and wear plate, that are the parts topic to probably the most stress, are made from extraordinarily durable chilled chrome forged iron, which withstands even abrasive substances such as sand within the pumped medium. In addition, the hydraulics were optimally designed for the working range utilizing computational fluid dynamics (CFD) to extend efficiency and to get rid of any chance of solids build up, which may negatively impression efficiency and result in costly pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids in the waste water and transport them away, saving each vitality and maintenance costs due to their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably appropriate for waste water applications that require excessive delivery stress, but at the identical time should cope with many alternative kinds of solids.”
HOMA will be presenting the new Alligator chopper pump collection for the primary time at IFAT 2022 in Munich. This and other innovations, such as the upkeep slide with sliding motor mount, shall be defined and demonstrated by the HOMA gross sales group in Hall B1 at Stand 429/528.
