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

Problematic solids similar to sanitary towels, plastic bags, textiles and wood are being found increasingly often in wastewater. Pumping and sewage treatment plants are subsequently more and more reaching their limits; items get clogged up and break down.
In times when low lifecycle costs are taking part in an ever extra necessary role, HOMA Pumpenfabrik offers an vitality environment friendly and reliable solution for areas the place a excessive delivery head is required, however at the same time, a various vary of solids is expected: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator collection permits effective operation via a powerful cutter system. Thanks to the use of extremely sturdy chilled chrome cast iron, the primary elements that are topic to essentially the most stress perform reliably even with abrasive substances similar to sand. HOMA will be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs are becoming increasingly important in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for power saving and dependable pumps that attain high supply heads with nice efficiency.” With its new Alligator chopper pump sequence, which may even be out there as an explosion-proof model, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our goal was to attain high supply pressures in the medium circulate fee range,” reports Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and extra power saving motor than in other pumps in the identical working range was enough. To obtain this, HOMA developed a model new cutter system that effectively shreds and removes large quantities of various solids corresponding to tear-resistant hygiene wipes, plastic baggage and wood, which also get into the wastewater by way of surface water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which can additionally be outfitted with its personal cutter. This design permits the 2 central components to work together to catch solids, break them down and finally remove them from the suction area through integrated grooves within the wear plate.
To enable larger efficiency without compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a end result, within the 50 Hz model, a move rate 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 power consumption of 8 to 20 kW, a flow price of up to a hundred and forty m³/h and a supply head of up to eighty two m are potential. The suction cover mounted on the pump housing can be used to regulate the slicing gap between the impeller and the wear and tear plate with the help of six set screws. “The strength of our new Alligator sequence, which is on the market for wet well installation in addition to dry set up, is its nice efficiency and efficient cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle prices due to wear-resistant design
In order to achieve not solely the very best efficiency values within the working vary required for these sorts of wastewater functions, but in addition to reduce lifecycle costs overall, HOMA attaches nice importance to low-maintenance operation along with efficiency. เกจวัดแรงดันถังลม and put on plate, that are the components subject to the most stress, are made of extraordinarily sturdy chilled chrome cast iron, which withstands even abrasive substances corresponding to sand in 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 build up, which might negatively impact performance and lead to pricey 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 maintenance costs due to their excessive efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water applications that require excessive delivery stress, but at the same time need to take care of many various sorts of solids.”
HOMA will be presenting the new Alligator chopper pump collection for the primary time at IFAT 2022 in Munich. This and other innovations, corresponding 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.
