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

Problematic solids similar to sanitary towels, plastic luggage, textiles and wooden are being discovered increasingly more usually in wastewater. Pumping and sewage remedy vegetation are therefore more and more reaching their limits; units get clogged up and break down.
In occasions when low lifecycle prices are enjoying an ever more essential position, HOMA Pumpenfabrik provides an power environment friendly and dependable resolution for areas the place a high delivery head is required, however at the similar time, a various range of solids is anticipated: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator series enables efficient operation by way of a powerful cutter system. Thanks to the utilization of highly sturdy chilled chrome forged iron, the principle components that are subject to the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA will be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle prices have gotten more and more essential 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 vitality saving and reliable pumps that reach excessive supply heads with great effectivity.” With its new Alligator chopper pump collection, which will also be available as an explosion-proof version, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our aim was to achieve excessive delivery pressures in the medium circulate rate range,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and extra energy saving motor than in other pumps in the same working range was enough. To achieve this, HOMA developed a brand new cutter system that effectively shreds and removes massive portions of various solids similar to tear-resistant hygiene wipes, plastic baggage and wooden, which additionally 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 wear plate, which is also equipped with its own cutter. This design allows the 2 central elements to work collectively to catch solids, break them down and finally remove them from the suction space through built-in 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 end result, in the 50 Hz version, a move fee of up to one hundred thirty m³/h and a supply head of up to 57 m could be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of 8 to 20 kW, a circulate rate of as a lot as 140 m³/h and a supply head of up to eighty two m are possible. The suction cowl mounted on the pump housing can be used to regulate the chopping gap between the impeller and the wear plate with the help of six set screws. “ เกจวัดแรงดันออกซิเจน of our new Alligator collection, which is out there for moist properly installation in addition to dry installation, is its great 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 achieve not only the best possible effectivity values within the working range required for these sorts of wastewater purposes, but in addition to reduce lifecycle costs general, HOMA attaches great importance to low-maintenance operation in addition to efficiency. The impeller and wear plate, which are the parts subject to essentially the most stress, are made from extremely durable chilled chrome forged iron, which withstands even abrasive substances similar to sand in the pumped medium. In addition, the hydraulics were optimally designed for the working vary using computational fluid dynamics (CFD) to extend effectivity and to remove any possibility of solids increase, which can negatively impression efficiency and lead to expensive 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 both energy and maintenance costs thanks to their excessive effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water functions that require high delivery strain, but at the identical time have to deal with many alternative sorts of solids.”
HOMA might be presenting the model new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and different improvements, such as the maintenance slide with sliding motor mount, shall be defined and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
