New chopper pump achieves high effectivity without compromising on chopping efficiency

pressure gauge 4 นิ้ว ราคา corresponding to sanitary towels, plastic luggage, textiles and wooden are being discovered increasingly often in wastewater. Pumping and sewage therapy plants are therefore more and more reaching their limits; models get clogged up and break down.
In instances when low lifecycle prices are taking half in an ever more important role, HOMA Pumpenfabrik presents an power efficient and reliable answer for areas where a high delivery head is required, however on the similar time, a diverse range of solids is expected: the Alligator chopper pump series. The newly developed OC impeller of the Alligator series enables efficient operation via a powerful cutter system. Thanks to the use of extremely sturdy chilled chrome forged iron, the principle components which would possibly be subject to the most stress perform reliably even with abrasive substances similar to sand. HOMA shall 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 essential in water and wastewater applications,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and dependable 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 model, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our objective was to achieve high supply pressures in the medium circulate fee vary,” reports Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and extra vitality saving motor than in different pumps in the same working vary was sufficient. To obtain this, HOMA developed a new cutter system that effectively shreds and removes large quantities of numerous solids corresponding to tear-resistant hygiene wipes, plastic bags and wood, which also get into the wastewater by way of floor water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear plate, which is also outfitted with its personal cutter. This design permits the 2 central elements to work collectively to catch solids, break them down and in the end take away them from the suction space by way of integrated grooves within the wear plate.
To allow greater effectivity with out compromising on chopping performance, the blades of the impeller also curve strongly backwards. As a end result, within the 50 Hz model, a circulate fee of up to a hundred thirty m³/h and a delivery head of as a lot as fifty seven m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of 8 to 20 kW, a flow price of as much as 140 m³/h and a supply head of up to 82 m are attainable. The suction cowl mounted on the pump housing may additionally be used to adjust the slicing gap between the impeller and the damage plate with the help of six set screws. “The energy of our new Alligator series, which is on the market for moist properly installation in addition to dry set up, is its nice effectivity and efficient cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle costs thanks to wear-resistant design
In order to attain not solely the greatest possible effectivity values in the operating vary required for these sorts of wastewater purposes, but also to reduce back lifecycle costs total, HOMA attaches nice importance to low-maintenance operation in addition to efficiency. The impeller and put on plate, which are the components topic to probably the most stress, are manufactured from extraordinarily sturdy chilled chrome cast 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 efficiency and to remove any chance of solids increase, which may negatively influence performance and lead to costly pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids within the waste water and transport them away, saving each energy and maintenance costs because of their excessive efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water functions that require excessive delivery strain, however at the identical time need to take care of many various kinds of solids.”
HOMA shall be presenting the brand new Alligator chopper pump series for the primary time at IFAT 2022 in Munich. This and other innovations, similar to the maintenance slide with sliding motor mount, will be defined and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
