New chopper pump achieves excessive effectivity without compromising on cutting efficiency

Problematic solids such as sanitary towels, plastic bags, textiles and wood are being found increasingly typically in wastewater. Pumping and sewage treatment vegetation are therefore increasingly reaching their limits; models get clogged up and break down.
In occasions when low lifecycle prices are taking half in an ever extra important function, HOMA Pumpenfabrik presents an power efficient and reliable resolution for areas where a excessive delivery head is required, however on the same time, a various vary of solids is anticipated: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator collection permits efficient operation by way of a strong cutter system. Thanks to using highly sturdy chilled chrome forged iron, the primary parts which would possibly be subject to the most stress carry out reliably even with abrasive substances similar to sand. HOMA might be presenting ตัววัดแรงดันน้ำมัน for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs are becoming increasingly necessary 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 vitality saving and reliable pumps that reach high delivery heads with great effectivity.” With its new Alligator chopper pump sequence, which may even be obtainable as an explosion-proof model, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our aim was to attain high delivery pressures in the medium flow rate range,” reviews Konstantin Pörsch. Without forfeiting pump fee, the improved efficiency meant that a smaller, cheaper and more vitality saving motor than in different pumps in the identical operating vary was adequate. To achieve this, HOMA developed a new cutter system that successfully shreds and removes giant quantities of diverse solids similar to tear-resistant hygiene wipes, plastic bags and wooden, which additionally get into the wastewater via surface water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear plate, which is also outfitted with its own cutter. This design permits the two central elements to work collectively to catch solids, break them down and ultimately remove them from the suction area via built-in grooves in the wear plate.
To allow higher efficiency without compromising on chopping performance, the blades of the impeller also curve strongly backwards. As a end result, in the 50 Hz version, a flow fee of as a lot as 130 m³/h and a delivery head of as much as fifty seven m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of eight to 20 kW, a circulate rate of as much as 140 m³/h and a delivery head of up to 82 m are possible. The suction cowl mounted on the pump housing can additionally be used to adjust the slicing gap between the impeller and the put on and tear plate with the help of six set screws. “The strength of our new Alligator collection, which is on the market for wet nicely installation as nicely as dry installation, is its great effectivity and effective cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle costs because of wear-resistant design
In order to achieve not only the best possible effectivity values in the operating vary required for these kinds of wastewater functions, but in addition to cut back lifecycle costs total, HOMA attaches great significance to low-maintenance operation in addition to effectivity. The impeller and put on plate, that are the elements topic to probably the most stress, are made of extraordinarily durable chilled chrome cast iron, which withstands even abrasive substances corresponding to sand within the pumped medium. In addition, the hydraulics have been optimally designed for the operating vary using computational fluid dynamics (CFD) to extend efficiency and to eliminate any possibility of solids building up, which might negatively impression performance and lead to costly pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids in the waste water and transport them away, saving each energy and maintenance prices because of their excessive efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water applications that require excessive supply pressure, but at the similar time should deal with many various kinds of solids.”
HOMA shall be presenting the model new Alligator chopper pump sequence for the first time at IFAT 2022 in Munich. This and other improvements, corresponding to the maintenance slide with sliding motor mount, might be explained and demonstrated by the HOMA gross sales staff in Hall B1 at Stand 429/528.
