New chopper pump achieves excessive effectivity without compromising on chopping performance

Problematic solids such as sanitary towels, plastic luggage, textiles and wooden are being found increasingly often in wastewater. Pumping and sewage therapy plants are therefore more and more reaching their limits; items get clogged up and break down.
In instances when low lifecycle costs are playing an ever extra necessary position, HOMA Pumpenfabrik presents an energy efficient and dependable answer for areas where a high delivery head is required, however on the same time, a various range of solids is anticipated: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator series enables effective operation via a robust cutter system. Thanks to the use of extremely sturdy chilled chrome forged iron, the main parts which would possibly be topic to probably the most stress perform reliably even with abrasive substances similar to sand. HOMA will be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs have gotten more and more necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and dependable pumps that reach high delivery heads with great efficiency.” With its new Alligator chopper pump series, which may also be available as an explosion-proof version, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our objective was to realize excessive delivery pressures within 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 different pumps in the identical operating range was adequate. To obtain this, HOMA developed a brand new cutter system that effectively shreds and removes large quantities of various solids corresponding to tear-resistant hygiene wipes, plastic baggage and wooden, which additionally get into the wastewater by way of surface water. The specially designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which is also outfitted with its own cutter. This design allows the two central components to work collectively to catch solids, break them down and ultimately remove them from the suction area by way of integrated grooves in the wear plate.
To enable higher efficiency with out compromising on cutting performance, the blades of the impeller also curve strongly backwards. As a end result, in the 50 Hz version, a flow rate of up to a hundred thirty m³/h and a supply head of as much as fifty seven m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of 8 to 20 kW, a flow rate of up to a hundred and forty m³/h and a delivery head of up to eighty two m are possible. The suction cowl mounted on the pump housing can be used to adjust the chopping hole between the impeller and the wear plate with the assist of six set screws. “The strength of our new Alligator series, which is out there for moist nicely installation as properly as dry installation, is its nice 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 achieve not solely the very best efficiency values within the working vary required for these kinds of wastewater applications, but additionally to scale back lifecycle costs general, HOMA attaches nice significance to low-maintenance operation in addition to effectivity. The impeller and wear plate, that are the components subject to the most stress, are manufactured from extremely sturdy chilled chrome cast iron, which withstands even abrasive substances similar to sand within the pumped medium. In addition, the hydraulics were optimally designed for the operating vary using computational fluid dynamics (CFD) to extend efficiency and to eliminate any risk of solids increase, which may negatively impact efficiency and lead to costly pump failures. “With เกจวัดแรง developed cutter system, the Alligator pumps can effectively break down all solids within the waste water and transport them away, saving both power and maintenance prices because of their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water applications that require high supply strain, but at the same time need to take care of many different kinds of solids.”
HOMA will be presenting the model new Alligator chopper pump series for the primary time at IFAT 2022 in Munich. This and other improvements, corresponding to the maintenance slide with sliding motor mount, will be defined and demonstrated by the HOMA sales group in Hall B1 at Stand 429/528.
