New chopper pump achieves excessive effectivity without compromising on chopping efficiency

Problematic solids corresponding to sanitary towels, plastic bags, textiles and wooden are being found more and more often in wastewater. Pumping and sewage treatment vegetation are therefore increasingly reaching their limits; models get clogged up and break down.
In times when low lifecycle costs are taking half in an ever more important position, HOMA Pumpenfabrik presents an vitality environment friendly and reliable resolution for areas the place a high supply head is required, but on the similar time, a various range of solids is predicted: the Alligator chopper pump sequence. เกจวัดแรงดันน้ำราคา developed OC impeller of the Alligator series enables efficient operation through a powerful cutter system. Thanks to using highly durable chilled chrome cast iron, the principle elements which may be subject to essentially the most stress perform reliably even with abrasive substances corresponding to sand. HOMA will be presenting เกจวัดแรงดันน้ำมันเบนซิน for the primary time at IFAT 2022 in Munich.
“The lowest attainable lifecycle prices have gotten more and more important in water and wastewater purposes,” 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 attain excessive supply heads with nice effectivity.” With its new Alligator chopper pump sequence, which may even be obtainable as an explosion-proof version, HOMA has developed a very environment friendly response to this demand.
Cutter system shreds all solids with high efficiency
“Our objective was to achieve high supply pressures in the medium circulate price range,” reports Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and extra 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 giant quantities of diverse solids such as tear-resistant hygiene wipes, plastic bags and wood, which also get into the wastewater by way of floor water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which can also be equipped with its personal cutter. This design allows the two central elements to work collectively to catch solids, break them down and finally take away them from the suction area via built-in grooves in the wear plate.
To allow larger effectivity without compromising on cutting efficiency, the blades of the impeller additionally curve strongly backwards. As a outcome, in the 50 Hz version, a move rate of as a lot as 130 m³/h and a supply head of as a lot as 57 m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of eight to twenty kW, a circulate fee of up to a hundred and forty m³/h and a delivery head of up to 82 m are attainable. The suction cowl mounted on the pump housing may also be used to adjust the chopping gap between the impeller and the damage plate with the aid of six set screws. “The strength of our new Alligator series, which is on the market for wet properly set up in addition to dry installation, is its nice efficiency and effective cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
Low lifecycle costs because of wear-resistant design
In order to realize not only the very best efficiency values in the working vary required for these kinds of wastewater purposes, but also to minimize back lifecycle costs general, HOMA attaches great importance to low-maintenance operation in addition to effectivity. The impeller and wear plate, which are the components subject to essentially the most stress, are manufactured from extraordinarily sturdy chilled chrome forged iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics were optimally designed for the working vary using computational fluid dynamics (CFD) to increase effectivity and to eliminate any possibility of solids increase, which might negatively impression performance and lead to pricey 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 both power and upkeep costs thanks to their high efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water functions that require high supply strain, however on the similar time have to deal with many various kinds of solids.”
HOMA will be presenting the brand new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and different innovations, similar to the maintenance slide with sliding motor mount, will be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
