Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wood are being discovered more and more usually in wastewater. Pumping and sewage therapy plants are subsequently increasingly reaching their limits; models get clogged up and break down.
In เกจวัดแรงดัน4บาร์ when low lifecycle prices are taking part in an ever more important function, HOMA Pumpenfabrik presents an vitality environment friendly and reliable answer for areas where a excessive delivery head is required, however on the similar time, a diverse range of solids is anticipated: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator sequence allows efficient operation through a robust cutter system. Thanks to the use of highly sturdy chilled chrome cast iron, the primary components that are subject to probably the most stress perform reliably even with abrasive substances such as sand. HOMA will be presenting the brand new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs have gotten more and more important 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 vitality saving and dependable pumps that attain high supply heads with great effectivity.” With its new Alligator chopper pump sequence, which may even be out there 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 attain high supply pressures within the medium circulate rate range,” stories Konstantin Pörsch. Without forfeiting pump fee, the improved efficiency meant that a smaller, cheaper and more vitality saving motor than in different pumps in the identical operating vary was sufficient. To obtain this, HOMA developed a new cutter system that effectively shreds and removes giant quantities of various solids similar to tear-resistant hygiene wipes, plastic baggage and wooden, which additionally get into the wastewater through floor water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear and tear plate, which can be outfitted with its own cutter. This design allows the 2 central elements to work collectively to catch solids, break them down and finally remove them from the suction space via built-in grooves in the wear plate.
To allow higher efficiency without compromising on slicing performance, the blades of the impeller also curve strongly backwards. As a outcome, within the 50 Hz version, a move fee of as a lot as one hundred thirty m³/h and a supply head of as much 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 twenty kW, a flow fee of as much as 140 m³/h and a supply head of up to eighty two m are possible. The suction cover mounted on the pump housing can additionally be used to regulate the cutting 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 moist properly installation as nicely as dry set up, is its nice effectivity and effective cutter system, coupled with a protracted 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 sorts of wastewater functions, but additionally to reduce lifecycle costs general, HOMA attaches great importance to low-maintenance operation along with effectivity. The impeller and wear plate, that are the elements subject to essentially the most stress, are made of extremely sturdy chilled chrome forged iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics have been optimally designed for the operating range utilizing computational fluid dynamics (CFD) to extend effectivity and to get rid of any risk of solids building up, which may negatively influence efficiency and lead to pricey 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 both energy and maintenance prices because of their excessive efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water applications that require excessive delivery strain, however at the identical time need to deal with many various sorts of solids.”
HOMA will be presenting the model new Alligator chopper pump series for the first 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.
