New chopper pump achieves high effectivity with out compromising on chopping efficiency

Problematic solids similar to sanitary towels, plastic bags, textiles and wooden are being found increasingly more usually in wastewater. Pumping and sewage treatment vegetation are due to this fact more and more reaching their limits; items get clogged up and break down.
In instances when low lifecycle costs are playing an ever extra important function, HOMA Pumpenfabrik offers an vitality efficient and dependable resolution for areas the place a high delivery head is required, however at the similar time, a diverse range of solids is anticipated: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection enables efficient operation by way of a strong cutter system. Thanks to the use of highly sturdy chilled chrome cast iron, the main elements that are subject to essentially the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA shall be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
เกจวัดแรงดันแก๊สอาร์กอน have gotten more and more necessary in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for energy saving and dependable pumps that reach high delivery heads with great efficiency.” With its new Alligator chopper pump series, which may 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 effectivity
“Our objective was to achieve high supply pressures within the medium flow fee vary,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and more vitality saving motor than in other pumps in the identical working range was sufficient. To achieve this, HOMA developed a new cutter system that successfully shreds and removes large portions of diverse solids corresponding to tear-resistant hygiene wipes, plastic baggage and wooden, which additionally get into the wastewater via floor water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which can be equipped with its personal cutter. This design allows the two central components to work collectively to catch solids, break them down and ultimately take away them from the suction area via integrated grooves within the wear plate.
To allow greater effectivity without compromising on chopping performance, the blades of the impeller also curve strongly backwards. As a result, in the 50 Hz model, a move price of as a lot as 130 m³/h and a delivery head of as much as 57 m could be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of 8 to 20 kW, a flow price of as much as one hundred forty m³/h and a supply head of as a lot as 82 m are attainable. The suction cowl mounted on the pump housing can also be used to regulate the slicing hole between the impeller and the wear plate with the aid of six set screws. “The power of our new Alligator sequence, which is available for moist well set up in addition to dry installation, is its nice efficiency and efficient cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
Low lifecycle prices due to wear-resistant design
In order to realize not solely the absolute best effectivity values within the working vary required for these sorts of wastewater applications, but in addition to scale back lifecycle prices overall, HOMA attaches great significance to low-maintenance operation in addition to efficiency. The impeller and wear plate, that are the components topic to probably the most stress, are made of extraordinarily durable chilled chrome forged iron, which withstands even abrasive substances similar to sand within the pumped medium. In addition, the hydraulics had been optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to extend efficiency and to remove any possibility of solids building up, which might negatively impression performance and lead to pricey pump failures. “With the newly developed cutter system, the Alligator pumps can successfully 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 notably suitable for waste water applications that require excessive delivery stress, however at the similar time should cope with many various sorts of solids.”
HOMA will be presenting the model new Alligator chopper pump series for the primary time at IFAT 2022 in Munich. This and different innovations, similar to the maintenance slide with sliding motor mount, might be defined and demonstrated by the HOMA sales group in Hall B1 at Stand 429/528.
