Problematic solids such as sanitary towels, plastic baggage, textiles and wood are being found more and more typically in wastewater. Pumping and sewage therapy crops are therefore more and more reaching their limits; items get clogged up and break down.
In occasions when low lifecycle costs are playing an ever extra necessary role, HOMA Pumpenfabrik provides an energy efficient and reliable resolution for areas where a excessive delivery head is required, but on the identical time, a various vary of solids is predicted: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator series permits effective operation by way of a robust cutter system. Thanks to the usage of extremely durable chilled chrome cast iron, the principle elements which are subject to the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA shall be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs have gotten increasingly necessary in water and wastewater functions,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for energy saving and dependable pumps that reach high supply heads with nice effectivity.” With เกจวัดแรงดันดิจิตอล , which may also be out there 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 within the medium move rate vary,” reviews Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and more power saving motor than in other pumps in the same operating range was enough. To achieve this, HOMA developed a new cutter system that successfully shreds and removes large quantities of numerous solids corresponding to tear-resistant hygiene wipes, plastic baggage and wooden, which additionally get into the wastewater by way of surface water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the wear plate, which is also geared up with its own cutter. This design allows the 2 central elements to work together to catch solids, break them down and finally remove them from the suction space via built-in grooves in the put on plate.
To enable greater efficiency without compromising on slicing efficiency, the blades of the impeller also curve strongly backwards. As a result, within the 50 Hz version, a flow price of up to 130 m³/h and a delivery head of as a lot as 57 m could be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of 8 to twenty kW, a flow price of as much as one hundred forty m³/h and a supply head of up to eighty two m are attainable. The suction cowl mounted on the pump housing can additionally be used to adjust the cutting gap between the impeller and the wear plate with assistance from six set screws. “The strength of our new Alligator sequence, which is available for moist properly set up as well as dry installation, is its great efficiency and effective cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
Low lifecycle costs thanks to wear-resistant design
In order to attain not only the very best efficiency values in the operating vary required for these sorts of wastewater functions, but additionally to minimize back lifecycle prices overall, HOMA attaches great importance to low-maintenance operation along with efficiency. The impeller and put on plate, which are the parts topic to essentially the most stress, are made from extraordinarily durable chilled chrome cast iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics have been optimally designed for the working range utilizing computational fluid dynamics (CFD) to increase effectivity and to eliminate any chance of solids building up, 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 each energy and upkeep prices due to their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly suitable for waste water functions that require high delivery strain, however on the same time have to take care of many alternative kinds of solids.”
HOMA will be presenting the brand new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and other improvements, similar to the upkeep slide with sliding motor mount, will be explained and demonstrated by the HOMA gross sales staff in Hall B1 at Stand 429/528.
