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

Problematic solids similar to sanitary towels, plastic bags, textiles and wooden are being found more and more usually in wastewater. Pumping and sewage therapy vegetation are therefore increasingly reaching their limits; items get clogged up and break down.
In เกจวัดแรงดันต่ำ when low lifecycle prices are playing an ever more necessary position, HOMA Pumpenfabrik offers an vitality environment friendly and reliable solution for areas where a excessive supply head is required, however at the similar time, a diverse vary of solids is expected: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator sequence permits efficient operation through a strong cutter system. Thanks to using extremely durable chilled chrome cast iron, the principle parts which would possibly be subject to the most stress carry out reliably even with abrasive substances such as sand. HOMA might be presenting the brand new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle prices are becoming increasingly important in water and wastewater functions,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for energy saving and dependable pumps that reach excessive delivery heads with great effectivity.” With its new Alligator chopper pump series, which will also be obtainable 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 in the medium circulate price vary,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and more power saving motor than in different pumps in the identical operating vary was enough. To achieve this, HOMA developed a model new cutter system that successfully shreds and removes giant quantities of diverse solids corresponding to tear-resistant hygiene wipes, plastic luggage and wooden, which also get into the wastewater by way of floor water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which can also be outfitted with its own cutter. This design allows the 2 central elements to work collectively to catch solids, break them down and finally remove them from the suction area by way of built-in grooves in the put on plate.
To allow greater efficiency without compromising on slicing performance, the blades of the impeller also curve strongly backwards. As a end result, in the 50 Hz version, a flow price of as much as a hundred thirty 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 20 kW, a circulate rate of up to 140 m³/h and a supply head of as much as eighty two m are attainable. 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 aid of six set screws. “The power of our new Alligator series, which is on the market for moist well installation in addition to dry installation, is its great effectivity and effective cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle costs thanks to wear-resistant design

In order to achieve not only the absolute best effectivity values within the operating vary required for these sorts of wastewater functions, but also to scale back lifecycle prices general, HOMA attaches great significance to low-maintenance operation in addition to efficiency. The impeller and put on plate, that are the parts subject to essentially the most stress, are manufactured from extraordinarily durable chilled chrome cast iron, which withstands even abrasive substances such as sand within the pumped medium. In addition, the hydraulics have been optimally designed for the operating range utilizing computational fluid dynamics (CFD) to increase efficiency and to eliminate any risk of solids increase, which may negatively impact efficiency 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 each energy and upkeep prices thanks to their high efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water purposes that require excessive delivery stress, but on the same time have to deal with many alternative sorts of solids.”

HOMA shall be presenting the brand new Alligator chopper pump collection for the primary time at IFAT 2022 in Munich. This and different innovations, similar to the upkeep slide with sliding motor mount, shall be defined and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
