New chopper pump achieves high efficiency with out compromising on chopping efficiency

Problematic solids such as sanitary towels, plastic baggage, textiles and wood are being discovered more and more typically in wastewater. Pumping and sewage remedy crops are therefore increasingly reaching their limits; models get clogged up and break down.
In times when low lifecycle prices are playing an ever extra necessary function, HOMA Pumpenfabrik presents an vitality efficient and dependable resolution for areas the place a excessive delivery head is required, however at the identical time, a various vary of solids is expected: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator series permits efficient operation by way of a strong cutter system. Thanks to using highly durable chilled chrome cast iron, the main components that are topic to the most stress perform reliably even with abrasive substances such as sand. HOMA will be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs have gotten more and more essential in water and wastewater applications,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for power saving and reliable pumps that attain excessive delivery heads with nice effectivity.” With its new Alligator chopper pump sequence, which may also be available as an explosion-proof model, HOMA has developed a very efficient response to this demand.

“Our objective was to realize high supply pressures within the medium move fee range,” reports Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and extra energy saving motor than in other pumps in the same operating range was sufficient. To achieve this, HOMA developed a new cutter system that successfully shreds and removes massive quantities of various solids corresponding to tear-resistant hygiene wipes, plastic luggage and wood, which additionally get into the wastewater through floor water. The specially designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the put on and tear plate, which is also equipped with its personal cutter. This design allows the 2 central parts to work collectively to catch solids, break them down and in the end take away them from the suction area through built-in grooves within the put on plate.
To allow greater effectivity without compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a outcome, in the 50 Hz version, a flow fee of up to one hundred thirty m³/h and a delivery head of up to fifty seven m can be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of eight to 20 kW, a flow rate of up to a hundred and forty m³/h and a supply head of up to eighty two m are possible. The suction cowl mounted on the pump housing may also be used to adjust the chopping gap between the impeller and the wear plate with assistance from six set screws. “The energy of our new Alligator sequence, which is out there for moist properly set up in addition to dry installation, is its great effectivity and effective cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to attain not only the absolute best effectivity values within the working vary required for these kinds of wastewater applications, but in addition to scale back lifecycle costs total, HOMA attaches great importance to low-maintenance operation in addition to efficiency. The impeller and wear plate, that are the parts topic to the most stress, are made from extremely durable chilled chrome cast iron, which withstands even abrasive substances similar to sand in the pumped medium. In addition, the hydraulics have been optimally designed for the working range utilizing computational fluid dynamics (CFD) to extend efficiency and to get rid of any possibility of solids building up, which might negatively impact performance and lead to pricey 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 vitality and maintenance costs due to their excessive effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water functions that require excessive supply stress, however at the identical time need to cope with many various kinds of solids.”
HOMA will be presenting the new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and other innovations, such as the maintenance slide with sliding motor mount, will be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
