New chopper pump achieves excessive efficiency with out compromising on slicing performance

Problematic solids corresponding to sanitary towels, plastic luggage, textiles and wood are being found increasingly often in wastewater. Pumping and sewage treatment crops are due to this fact increasingly reaching their limits; models get clogged up and break down.
In instances when low lifecycle costs are enjoying an ever more essential function, HOMA Pumpenfabrik provides an vitality efficient and reliable resolution for areas the place a excessive supply head is required, however on the same time, a various range of solids is predicted: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator collection allows efficient operation through a powerful cutter system. Thanks to the use of extremely sturdy chilled chrome forged iron, the primary components that are topic to probably the most stress perform reliably even with abrasive substances such as sand. HOMA will be presenting the model new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs have gotten increasingly essential in water and wastewater purposes,” 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 supply heads with great effectivity.” With its new Alligator chopper pump sequence, which may even be available as an explosion-proof model, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with high efficiency
“Our goal was to achieve excessive delivery pressures in the medium circulate rate range,” stories Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and more power saving motor than in other pumps in the same working vary was sufficient. To obtain this, HOMA developed a new cutter system that effectively shreds and removes giant portions of numerous solids such as tear-resistant hygiene wipes, plastic bags and wooden, which also get into the wastewater through floor water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which is also geared up with its own cutter. This design permits the 2 central elements to work collectively to catch solids, break them down and in the end remove them from the suction area by way of built-in grooves in the wear plate.
To enable greater efficiency with out compromising on cutting efficiency, the blades of the impeller also curve strongly backwards. As a end result, in the 50 Hz version, a flow price of up to one hundred thirty m³/h and a supply head of as much as fifty seven m can be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of eight to 20 kW, a move rate of as a lot as a hundred and forty m³/h and a supply head of up to eighty two m are possible. The suction cover mounted on the pump housing can also be used to regulate the cutting hole between the impeller and the wear plate with assistance from six set screws. “ pressure gauge ราคา of our new Alligator collection, which is available for moist nicely installation in addition to dry set up, is its great efficiency and effective cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle costs because of wear-resistant design
In order to attain not only the absolute best effectivity values within the operating vary required for these kinds of wastewater applications, but also to cut back lifecycle prices general, HOMA attaches great importance to low-maintenance operation along with effectivity. The impeller and wear plate, which are the components subject to the most stress, are made of extremely sturdy chilled chrome forged iron, which withstands even abrasive substances similar to sand in the pumped medium. In addition, the hydraulics had been optimally designed for the operating range utilizing computational fluid dynamics (CFD) to increase efficiency and to get rid of any risk of solids increase, which might negatively impression efficiency and result in expensive pump failures. “With the newly developed cutter system, the Alligator pumps can successfully break down all solids within the waste water and transport them away, saving each power and maintenance prices thanks to their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water functions that require excessive supply strain, but on the same time need to cope with many different kinds of solids.”
HOMA might be presenting the new Alligator chopper pump sequence for the first time at IFAT 2022 in Munich. This and other innovations, such as the maintenance slide with sliding motor mount, shall be explained and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
