เกจวัดแรงดันน้ำ10บาร์ to sanitary towels, plastic luggage, textiles and wooden are being discovered increasingly more often in wastewater. Pumping and sewage remedy plants are therefore increasingly reaching their limits; units get clogged up and break down.
In times when low lifecycle prices are playing an ever more necessary position, HOMA Pumpenfabrik offers an power environment friendly and reliable resolution for areas where a high delivery head is required, however at the similar time, a diverse range of solids is anticipated: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator series allows effective operation through a strong cutter system. Thanks to using highly durable chilled chrome forged iron, the primary parts which might be topic to probably the most stress perform reliably even with abrasive substances similar to sand. HOMA might be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest attainable lifecycle prices have gotten more and more essential in water and wastewater functions,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for energy saving and reliable pumps that attain excessive delivery heads with great efficiency.” With its new Alligator chopper pump collection, which may even be available as an explosion-proof version, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with high effectivity
“Our goal was to realize excessive delivery pressures within the medium circulate price range,” reviews Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and more energy saving motor than in other pumps in the identical working vary was sufficient. To achieve this, HOMA developed a new cutter system that effectively shreds and removes giant portions of various solids corresponding to tear-resistant hygiene wipes, plastic bags and wooden, 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 wear plate, which can also be equipped with its own cutter. This design allows the two central elements to work collectively to catch solids, break them down and ultimately take away them from the suction area by way of built-in grooves in the wear plate.
To enable larger effectivity with out compromising on cutting efficiency, the blades of the impeller also curve strongly backwards. As a result, in the 50 Hz model, a move fee of as much as 130 m³/h and a supply head of as a lot as 57 m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of 8 to twenty kW, a flow fee of as much as a hundred and forty m³/h and a delivery head of as a lot as 82 m are possible. The suction cowl mounted on the pump housing can additionally be used to regulate the cutting gap between the impeller and the wear and tear plate with assistance from six set screws. “The energy of our new Alligator series, which is out there for moist nicely set up as nicely as dry set up, is its nice effectivity and efficient cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle costs thanks to wear-resistant design
In order to achieve not only the greatest possible efficiency values in the operating vary required for these sorts of wastewater functions, but in addition to reduce lifecycle costs general, HOMA attaches great importance to low-maintenance operation along with efficiency. The impeller and put on plate, which are the elements subject to the most stress, are made of extremely durable chilled chrome cast iron, which withstands even abrasive substances similar to sand in the pumped medium. In addition, the hydraulics had been optimally designed for the working range utilizing computational fluid dynamics (CFD) to extend efficiency and to get rid of any chance of solids building up, which might negatively impression performance and lead to 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 power and upkeep costs thanks to their high efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water applications that require excessive delivery strain, but on the same time have to deal with many alternative kinds of solids.”
HOMA might be presenting the model new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and other improvements, such as the upkeep slide with sliding motor mount, will be explained and demonstrated by the HOMA sales group in Hall B1 at Stand 429/528.
