New chopper pump achieves excessive efficiency without compromising on cutting efficiency

Problematic solids similar to sanitary towels, plastic baggage, textiles and wood are being found increasingly more typically in wastewater. Pumping and sewage remedy crops are therefore more and more reaching their limits; items get clogged up and break down.
In occasions when low lifecycle prices are playing an ever extra necessary function, HOMA Pumpenfabrik offers an vitality environment friendly and reliable resolution for areas the place a excessive supply head is required, but on the identical time, a various range of solids is expected: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator series allows effective operation by way of a robust cutter system. Thanks to the usage of highly durable chilled chrome cast iron, the principle parts which would possibly be topic to essentially the most stress perform reliably even with abrasive substances such as sand. HOMA might be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest potential lifecycle prices have gotten more and more necessary 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 vitality saving and reliable pumps that attain high delivery heads with nice effectivity.” With its new Alligator chopper pump series, which may also be out there as an explosion-proof version, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our objective was to attain excessive delivery pressures in the medium flow fee vary,” reports 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 operating vary was adequate. To obtain this, HOMA developed a brand new cutter system that effectively shreds and removes massive portions of diverse solids such as tear-resistant hygiene wipes, plastic baggage and wood, which also get into the wastewater through surface water. The specially designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the wear plate, which can also be outfitted with its own cutter. This design permits the two central components to work together to catch solids, break them down and finally take away them from the suction space by way of built-in grooves within the put on plate.
To allow higher effectivity with out compromising on chopping performance, the blades of the impeller also curve strongly backwards. As a result, in the 50 Hz version, a flow price of up to a hundred thirty m³/h and a supply head of as a lot as 57 m can be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of eight to twenty kW, a move price of up to 140 m³/h and a supply head of as a lot as 82 m are possible. The suction cover mounted on the pump housing can be used to adjust the slicing gap between the impeller and the damage plate with the aid of six set screws. “The power of our new Alligator sequence, which is out there for wet properly set up as nicely as dry set up, is its great efficiency and effective cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to realize not only the best possible effectivity values within the operating vary required for these sorts of wastewater purposes, but also to reduce lifecycle prices overall, HOMA attaches nice importance to low-maintenance operation along with effectivity. เพชเชอร์เกจ and wear plate, that are the components subject to probably the most stress, are manufactured from extremely durable chilled chrome cast iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics were optimally designed for the operating range utilizing computational fluid dynamics (CFD) to extend efficiency and to remove any chance of solids building up, which may negatively influence 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 both vitality and upkeep costs because of their excessive efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water purposes that require excessive supply pressure, however at the similar time should cope with many alternative kinds of solids.”
HOMA shall be presenting the model new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and other innovations, similar to the upkeep slide with sliding motor mount, might be defined and demonstrated by the HOMA gross sales group in Hall B1 at Stand 429/528.
