New chopper pump achieves excessive effectivity with out compromising on chopping efficiency

Problematic solids such as sanitary towels, plastic baggage, textiles and wooden are being found increasingly more typically in wastewater. Pumping and sewage therapy vegetation are subsequently increasingly reaching their limits; models get clogged up and break down.
In instances when low lifecycle prices are taking part in an ever extra essential function, HOMA Pumpenfabrik provides an vitality environment friendly and reliable resolution for areas the place a excessive supply head is required, however on the same time, a various vary of solids is predicted: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection enables efficient operation through a strong cutter system. Thanks to using extremely durable chilled chrome cast iron, the main parts which are topic to the most stress carry out reliably even with abrasive substances similar to sand. HOMA will be presenting the model new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs are becoming more and more necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for energy saving and reliable pumps that reach high delivery heads with nice efficiency.” With Unconditional , which may also be out there as an explosion-proof model, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with high efficiency
“Our objective was to attain excessive supply pressures in the medium flow rate vary,” reviews Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and extra vitality saving motor than in different pumps in the same working vary was sufficient. To achieve this, HOMA developed a new cutter system that successfully shreds and removes large quantities of diverse solids similar to tear-resistant hygiene wipes, plastic bags and wooden, which additionally get into the wastewater via surface water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the put on and tear plate, which is also geared up with its own cutter. This design allows the two central parts to work together to catch solids, break them down and ultimately take away them from the suction space by way of integrated grooves within the wear plate.
To enable higher efficiency with out compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a end result, within the 50 Hz model, a flow fee of up to one hundred thirty m³/h and a delivery head of as much as 57 m can 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 price of as much as 140 m³/h and a delivery head of as much as eighty two m are potential. The suction cowl mounted on the pump housing can be used to adjust the slicing hole between the impeller and the wear plate with the help of six set screws. “The energy of our new Alligator series, which is on the market for moist nicely set up in addition to dry installation, is its great effectivity and efficient cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle costs because of wear-resistant design
In order to attain not only the absolute best effectivity values within the operating vary required for these kinds of wastewater functions, but also to cut back lifecycle prices overall, HOMA attaches nice significance to low-maintenance operation in addition to effectivity. The impeller and put on plate, which are the parts subject to essentially the most stress, are made of extremely sturdy chilled chrome forged iron, which withstands even abrasive substances corresponding to sand within the pumped medium. In addition, the hydraulics have been optimally designed for the operating range utilizing computational fluid dynamics (CFD) to extend effectivity and to get rid of any risk of solids increase, which might negatively influence 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 each energy and maintenance prices because of their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water functions that require excessive supply stress, however on the identical time need to deal with many various sorts of solids.”
HOMA might be presenting the brand new Alligator chopper pump series for the primary time at IFAT 2022 in Munich. This and other innovations, similar to the upkeep slide with sliding motor mount, might be explained and demonstrated by the HOMA sales group in Hall B1 at Stand 429/528.
