New chopper pump achieves high effectivity with out compromising on slicing performance

Problematic solids such as sanitary towels, plastic bags, textiles and wooden are being found increasingly more typically in wastewater. Pumping and sewage treatment vegetation are subsequently increasingly reaching their limits; items get clogged up and break down.
In times when low lifecycle costs are playing an ever extra important function, HOMA Pumpenfabrik presents an vitality environment friendly and reliable solution for areas the place a excessive delivery head is required, but on the same time, a various range of solids is predicted: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator sequence enables efficient operation through a robust cutter system. Thanks to the use of extremely durable chilled chrome forged iron, the main elements that are topic to probably the most stress carry out reliably even with abrasive substances such as sand. HOMA shall be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs are becoming increasingly important in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for vitality saving and dependable pumps that attain excessive delivery heads with great effectivity.” With its new Alligator chopper pump collection, which may even be obtainable as an explosion-proof model, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our aim was to achieve excessive delivery pressures in the medium flow rate vary,” stories Konstantin Pörsch. Without forfeiting pump fee, the improved efficiency meant that a smaller, cheaper and extra vitality saving motor than in different pumps in the identical working range was sufficient. To achieve this, HOMA developed a model new cutter system that effectively shreds and removes massive quantities of various solids such as tear-resistant hygiene wipes, plastic luggage and wood, which additionally get into the wastewater by way of floor water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the put on and tear plate, which is also outfitted with its personal cutter. This design allows the two central parts to work collectively to catch solids, break them down and ultimately take away them from the suction space through built-in grooves within the put on plate.
To allow greater effectivity with out compromising on cutting performance, the blades of the impeller also curve strongly backwards. As a outcome, within the 50 Hz version, a circulate price of up to a hundred thirty m³/h and a supply 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 energy consumption of eight to twenty kW, a move price of up to one hundred forty m³/h and a supply head of up to 82 m are possible. The suction cover mounted on the pump housing may additionally be used to adjust the chopping hole between the impeller and the wear and tear plate with the help of six set screws. “The strength of our new Alligator collection, which is out there for wet well installation as properly as dry installation, is its great effectivity and efficient cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.

In order to achieve not solely the absolute best effectivity values within the operating range required for these sorts of wastewater applications, but in addition to reduce back lifecycle costs total, HOMA attaches great significance to low-maintenance operation in addition to effectivity. The impeller and put on plate, that are the elements topic to probably the most stress, are manufactured from extraordinarily durable chilled chrome forged iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics had been optimally designed for the working vary using computational fluid dynamics (CFD) to increase effectivity and to eliminate any possibility of solids build up, which may negatively influence performance and lead to 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 power and upkeep costs because of their excessive efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water applications that require excessive supply stress, but at the similar time have to cope 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 improvements, similar to the maintenance slide with sliding motor mount, might be defined and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
