Problematic solids similar to sanitary towels, plastic luggage, textiles and wooden are being discovered increasingly usually in wastewater. Pumping and sewage treatment plants are therefore increasingly reaching their limits; units get clogged up and break down.
In instances when low lifecycle costs are taking half in an ever more important role, HOMA Pumpenfabrik provides an energy efficient and reliable answer for areas where a excessive delivery head is required, but at the identical time, a various range of solids is predicted: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection enables efficient operation by way of a strong cutter system. Thanks to the utilization of highly sturdy chilled chrome cast iron, the principle parts which are subject to essentially the most stress perform reliably even with abrasive substances corresponding to sand. HOMA shall be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs have gotten more and more necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and reliable pumps that attain high supply heads with great efficiency.” With its new Alligator chopper pump series, which may also be available as an explosion-proof version, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with high effectivity
“Our goal was to achieve excessive delivery pressures within the medium move fee range,” reviews Konstantin Pörsch. Without forfeiting pump rate, the improved effectivity meant that a smaller, cheaper and extra vitality saving motor than in other pumps in the identical working range was enough. To achieve this, HOMA developed a model new cutter system that successfully shreds and removes large portions of diverse solids similar to tear-resistant hygiene wipes, plastic baggage and wood, which also get into the wastewater by way of surface water. เกจวัดแรงดูด designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which can additionally be geared up with its personal cutter. This design permits the two central parts to work collectively to catch solids, break them down and finally take away them from the suction area by way of built-in grooves in the wear plate.
To enable higher effectivity without compromising on chopping efficiency, the blades of the impeller additionally curve strongly backwards. As a end result, within the 50 Hz model, a circulate fee of as a lot as a hundred thirty m³/h and a delivery head of up to 57 m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of 8 to 20 kW, a flow price of up to 140 m³/h and a delivery head of up to eighty two m are potential. The suction cover mounted on the pump housing can be used to regulate the chopping gap between the impeller and the damage plate with assistance from six set screws. “The strength of our new Alligator collection, which is available for moist well set up in addition to dry installation, is its great efficiency and efficient cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design
In order to realize not solely the greatest possible efficiency values in the working vary required for these kinds of wastewater applications, but in addition to reduce lifecycle prices general, HOMA attaches nice significance to low-maintenance operation along with efficiency. The impeller and put on plate, that are the elements topic to probably the most stress, are made of extremely durable chilled chrome forged iron, which withstands even abrasive substances similar to sand within the pumped medium. In addition, the hydraulics were optimally designed for the working range utilizing computational fluid dynamics (CFD) to increase effectivity and to get rid of any risk of solids building up, which may negatively influence efficiency and result in 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 both energy and maintenance prices due to their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water functions that require high supply stress, but at the identical time should cope with many alternative sorts of solids.”
HOMA shall be presenting the model new Alligator chopper pump collection for the first time at IFAT 2022 in Munich. This and different improvements, corresponding to the upkeep slide with sliding motor mount, might be defined and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
