New chopper pump achieves high efficiency with out compromising on cutting performance

Problematic solids such as sanitary towels, plastic baggage, textiles and wooden are being found increasingly typically in wastewater. Pumping and sewage remedy plants are subsequently increasingly reaching their limits; models get clogged up and break down.
In instances when low lifecycle costs are playing an ever more necessary function, HOMA Pumpenfabrik provides an vitality efficient and reliable solution for areas where a high supply head is required, however on the similar time, a diverse vary of solids is anticipated: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator collection permits efficient operation through a powerful cutter system. Thanks to the use of extremely durable chilled chrome cast iron, the primary components that are subject to essentially the most stress carry out reliably even with abrasive substances such as sand. HOMA shall be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle prices are becoming increasingly essential in water and wastewater functions,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is pressure gauge 4 นิ้ว growing demand for power saving and dependable pumps that reach high supply heads with great effectivity.” With its new Alligator chopper pump sequence, which may also be out there as an explosion-proof version, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our goal was to achieve excessive supply pressures within the medium circulate price range,” reports Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and more vitality saving motor than in other pumps in the same working vary was enough. To achieve this, HOMA developed a model new cutter system that effectively shreds and removes massive portions of numerous solids corresponding to tear-resistant hygiene wipes, plastic baggage and wood, which additionally get into the wastewater by way of floor water. The specially designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the wear and tear plate, which can additionally be geared up with its personal cutter. This design permits the 2 central components to work collectively to catch solids, break them down and finally remove them from the suction area through integrated grooves in the wear plate.
To allow larger efficiency without compromising on chopping performance, the blades of the impeller also curve strongly backwards. As a outcome, in the 50 Hz model, a move rate of as a lot as 130 m³/h and a supply head of as a lot as 57 m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of 8 to twenty kW, a move rate of as much as one hundred forty m³/h and a delivery head of as much as eighty two m are possible. The suction cowl mounted on the pump housing can additionally be used to regulate the slicing gap between the impeller and the wear plate with the help of six set screws. “ เครื่องมือวัดความดัน of our new Alligator sequence, which is out there for moist nicely set up as nicely as dry installation, is its nice efficiency and efficient cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to realize not only the best possible efficiency values in the working range required for these kinds of wastewater functions, but also to cut back lifecycle prices general, HOMA attaches nice significance to low-maintenance operation in addition to effectivity. The impeller and put on plate, which are the components subject to probably the most stress, are made of extremely durable chilled chrome cast iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics were optimally designed for the working range utilizing computational fluid dynamics (CFD) to extend effectivity and to eliminate any chance of solids increase, which may negatively impression performance and result in 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 upkeep costs due to their high efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly suitable for waste water purposes that require excessive delivery stress, however on the identical time have to deal with many various sorts of solids.”
HOMA might be presenting the model new Alligator chopper pump collection for the primary time at IFAT 2022 in Munich. This and different innovations, corresponding to the maintenance slide with sliding motor mount, might be defined and demonstrated by the HOMA sales group in Hall B1 at Stand 429/528.
