Problematic solids corresponding to sanitary towels, plastic bags, textiles and wooden are being discovered increasingly more typically in wastewater. Pumping and sewage therapy crops are due to this fact more and more reaching their limits; items get clogged up and break down.
In เครื่องมือที่ใช้วัดความดัน when low lifecycle prices are enjoying an ever more necessary position, HOMA Pumpenfabrik provides an power environment friendly and reliable solution for areas the place a high delivery head is required, but on the similar time, a diverse range of solids is anticipated: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator sequence permits effective operation by way of a strong cutter system. Thanks to the use of extremely durable chilled chrome cast iron, the principle parts that are topic to essentially the most stress carry out reliably even with abrasive substances similar to sand. HOMA will be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle prices are becoming increasingly important in water and wastewater applications,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for power saving and dependable pumps that attain high supply heads with great efficiency.” With its new Alligator chopper pump series, which may also be obtainable as an explosion-proof model, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with high effectivity
“Our objective was to attain high supply pressures in the medium move fee range,” stories Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and more energy saving motor than in other pumps in the same operating range was adequate. To achieve this, HOMA developed a model new cutter system that successfully shreds and removes giant quantities of diverse solids such as tear-resistant hygiene wipes, plastic luggage and wood, which additionally get into the wastewater via floor water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which can be geared up with its personal cutter. This design allows the two central parts to work collectively to catch solids, break them down and ultimately take away them from the suction area via integrated grooves within the wear plate.
To allow greater effectivity without compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a end result, within the 50 Hz model, a move rate of as much as 130 m³/h and a delivery head of up to fifty seven m can be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of eight to twenty kW, a flow fee of as much as a hundred and forty m³/h and a supply head of as a lot as 82 m are attainable. The suction cover mounted on the pump housing can additionally be used to adjust the chopping gap between the impeller and the damage plate with the help of six set screws. “The energy of our new Alligator sequence, which is on the market for wet well set up as properly as dry installation, is its nice effectivity and efficient cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to achieve not only the very best efficiency values in the operating vary required for these sorts of wastewater purposes, but in addition to scale back lifecycle prices overall, HOMA attaches great importance to low-maintenance operation in addition to effectivity. The impeller and put on plate, which are the elements subject to probably the most stress, are made of extraordinarily durable chilled chrome cast iron, which withstands even abrasive substances similar to sand within the pumped medium. In addition, the hydraulics had been optimally designed for the working vary using computational fluid dynamics (CFD) to increase effectivity and to get rid of any chance of solids building up, which might negatively influence performance and result in 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 thanks to their excessive efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water functions that require high delivery stress, however at the similar time should take care of many alternative sorts of solids.”
HOMA shall be presenting the new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and other innovations, such as the maintenance slide with sliding motor mount, will be defined and demonstrated by the HOMA gross sales group in Hall B1 at Stand 429/528.
