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

Problematic solids such as sanitary towels, plastic luggage, textiles and wood are being discovered more and more usually in wastewater. Pumping and sewage remedy plants are subsequently more and more reaching their limits; units get clogged up and break down.
In occasions when low lifecycle prices are taking half in an ever extra important function, HOMA Pumpenfabrik offers an vitality efficient and reliable resolution for areas where a excessive delivery head is required, but at the identical time, a diverse range of solids is anticipated: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator sequence allows efficient operation by way of a robust cutter system. Thanks to the utilization of highly durable chilled chrome forged iron, the main parts which would possibly be topic to probably 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.
“The lowest possible lifecycle prices have gotten increasingly important 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 reliable pumps that attain excessive supply heads with nice effectivity.” With its new Alligator chopper pump sequence, which will also be out there as an explosion-proof version, HOMA has developed a particularly environment friendly response to this demand.
ไดอะแฟรม with high efficiency

“Our objective was to realize excessive delivery pressures within the medium circulate fee vary,” stories Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and extra power saving motor than in different pumps in the identical operating range was enough. To obtain this, HOMA developed a new cutter system that effectively shreds and removes massive quantities of numerous solids such as tear-resistant hygiene wipes, plastic luggage and wooden, which additionally get into the wastewater via surface water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the put on and tear plate, which can also be outfitted with its personal cutter. This design permits the 2 central components to work together to catch solids, break them down and ultimately remove them from the suction area through integrated grooves in the put on plate.
To enable higher efficiency with out compromising on cutting efficiency, the blades of the impeller also curve strongly backwards. As a result, within the 50 Hz model, a move fee of as a lot as a hundred thirty 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 eight to 20 kW, a move fee of as a lot as a hundred and forty m³/h and a delivery head of as much as 82 m are potential. The suction cover mounted on the pump housing can additionally be used to regulate the cutting gap between the impeller and the damage plate with the aid of six set screws. “The power of our new Alligator series, which is available for wet well set up as nicely as dry installation, is its great effectivity and effective cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle costs because of wear-resistant design

In order to realize not solely the best possible effectivity values in the operating vary required for these sorts of wastewater purposes, but also to reduce lifecycle prices total, HOMA attaches great significance to low-maintenance operation along with efficiency. The impeller and wear plate, which are the parts topic to probably the most stress, are manufactured from extremely sturdy chilled chrome cast iron, which withstands even abrasive substances corresponding to sand within the pumped medium. In addition, the hydraulics had been optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to increase effectivity and to eliminate any possibility of solids building up, which may negatively impression performance and result in expensive pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids within the waste water and transport them away, saving each energy and upkeep costs due to their excessive effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water purposes that require excessive supply pressure, however on the identical time should deal with many alternative kinds of solids.”

HOMA might 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 upkeep slide with sliding motor mount, shall be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
