New chopper pump achieves excessive efficiency without compromising on slicing efficiency

Problematic solids corresponding to sanitary towels, plastic luggage, textiles and wood are being found increasingly usually in wastewater. Pumping and sewage therapy plants are therefore more and more reaching their limits; units get clogged up and break down.
In instances when low lifecycle costs are taking half in an ever extra necessary position, HOMA Pumpenfabrik presents an vitality efficient and reliable resolution for areas the place a excessive supply head is required, but on the identical time, a various range of solids is predicted: the Alligator chopper pump series. The newly developed OC impeller of the Alligator series permits effective operation via a strong cutter system. Thanks to the usage of extremely durable chilled chrome cast iron, the main elements that are topic to probably the most stress perform reliably even with abrasive substances similar to sand. HOMA will be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs have gotten increasingly necessary 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 reach high supply heads with great efficiency.” With its new Alligator chopper pump collection, which may also be available as an explosion-proof version, HOMA has developed a very environment friendly response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our aim was to attain excessive delivery pressures in the medium move price range,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and more energy saving motor than in other pumps in the same working range was adequate. To achieve this, HOMA developed a model new cutter system that successfully shreds and removes massive quantities of diverse solids similar to tear-resistant hygiene wipes, plastic luggage and wooden, which additionally get into the wastewater via surface water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which is also outfitted with its own cutter. This design allows the 2 central parts to work together to catch solids, break them down and ultimately take away them from the suction space through integrated grooves in the put on plate.
To enable larger efficiency without compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a outcome, in the 50 Hz model, a flow price of as much as 130 m³/h and a supply head of up to 57 m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of 8 to twenty kW, a circulate rate of up to one hundred forty m³/h and a supply head of as much as 82 m are possible. The suction cowl mounted on the pump housing can be used to regulate the cutting gap between the impeller and the damage plate with assistance from six set screws. “The energy of our new Alligator collection, which is out there for wet properly set up in addition to dry installation, is its great efficiency and effective cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design
In order to achieve not only the very best effectivity values within the operating vary required for these kinds of wastewater functions, but in addition to reduce lifecycle prices total, HOMA attaches nice importance to low-maintenance operation in addition to effectivity. เกจวัดแรงดันอาร์กอน and wear plate, which are the components topic to essentially the most stress, are made from extremely sturdy chilled chrome forged iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics had been optimally designed for the working vary utilizing computational fluid dynamics (CFD) to extend efficiency and to eliminate any risk of solids build up, which might negatively influence efficiency and result in 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 vitality and maintenance prices because of their excessive effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water applications that require excessive delivery strain, but at the identical time should deal with many alternative kinds of solids.”
HOMA might be presenting the model new Alligator chopper pump collection for the primary time at IFAT 2022 in Munich. This and other improvements, corresponding to the upkeep slide with sliding motor mount, will be defined and demonstrated by the HOMA gross sales group in Hall B1 at Stand 429/528.
