New chopper pump achieves high effectivity without compromising on slicing performance

Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wood are being found more and more usually in wastewater. Pumping and sewage remedy plants are therefore more and more reaching their limits; items get clogged up and break down.
In times when low lifecycle prices are taking half in an ever more important role, HOMA Pumpenfabrik presents an vitality environment friendly and reliable solution for areas where a high supply head is required, however at the identical time, a diverse vary of solids is anticipated: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator collection permits effective operation by way of a powerful cutter system. Thanks to the utilization of extremely durable chilled chrome cast iron, the principle components which may be topic to essentially the most stress perform reliably even with abrasive substances such as sand. HOMA shall be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest possible lifecycle prices have gotten increasingly essential 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 power saving and reliable pumps that reach high supply heads with nice effectivity.” With เกจวัดแรงดันแก๊สco2 , which will also be available as an explosion-proof model, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our objective was to attain excessive supply pressures within the medium move rate vary,” reports Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and extra energy saving motor than in other pumps in the identical working range was sufficient. To obtain this, HOMA developed a new cutter system that effectively shreds and removes massive quantities of numerous solids such as tear-resistant hygiene wipes, plastic baggage and wood, which additionally get into the wastewater by way of floor water. The specially designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which can also be geared up with its own cutter. This design allows the 2 central elements to work together to catch solids, break them down and ultimately take away them from the suction area by way of built-in grooves within the put on plate.
To enable larger effectivity with out compromising on chopping efficiency, the blades of the impeller additionally curve strongly backwards. As a result, within the 50 Hz model, a circulate price of as much as a hundred thirty m³/h and a delivery head of up to fifty seven m can be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of eight to 20 kW, a move rate of up to a hundred and forty m³/h and a supply head of as a lot as 82 m are possible. The suction cowl mounted on the pump housing can additionally be used to adjust the chopping gap between the impeller and the wear and tear plate with the aid of six set screws. “The energy of our new Alligator collection, which is available for wet nicely installation in addition to dry set up, is its great effectivity and effective cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design
In order to attain not only the absolute best efficiency values in the working vary required for these kinds of wastewater applications, but additionally to scale back lifecycle prices overall, HOMA attaches great importance to low-maintenance operation along with effectivity. The impeller and wear plate, that are the components topic to probably the most stress, are made of extremely sturdy chilled chrome cast 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 utilizing computational fluid dynamics (CFD) to extend efficiency and to get rid of any risk of solids build up, which can negatively influence performance and result in expensive 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 power and upkeep prices due to their excessive efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly suitable for waste water purposes that require excessive delivery pressure, but on the similar 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 other improvements, similar 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.
