Problematic solids corresponding to sanitary towels, plastic bags, textiles and wooden are being discovered increasingly usually in wastewater. Pumping and sewage therapy plants are due to this fact more and more reaching their limits; items get clogged up and break down.
In instances when low lifecycle costs are enjoying an ever extra important function, HOMA Pumpenfabrik provides an power efficient and reliable answer for areas the place a excessive delivery head is required, however at the identical time, a diverse range of solids is expected: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection allows effective operation by way of a powerful cutter system. Thanks to using highly durable chilled chrome cast iron, the main parts that are subject to essentially the most stress perform reliably even with abrasive substances such as sand. HOMA might be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs have gotten more and more necessary in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for vitality saving and reliable pumps that reach high delivery heads with nice efficiency.” With its new Alligator chopper pump series, which may also be available as an explosion-proof version, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with high efficiency
“Our objective was to realize excessive supply pressures within the medium flow fee range,” stories Konstantin Pörsch. Without forfeiting pump rate, the improved effectivity meant that a smaller, cheaper and more vitality saving motor than in different pumps in the same working range was enough. To achieve this, HOMA developed a new cutter system that successfully shreds and removes large quantities of diverse solids corresponding to tear-resistant hygiene wipes, plastic luggage and wood, which additionally get into the wastewater by way of surface water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which can be equipped with its own cutter. This design allows the two central elements to work collectively to catch solids, break them down and ultimately take away them from the suction space through integrated grooves within the wear plate.
To enable เกจ์แรงดัน with out compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a result, within the 50 Hz version, a flow fee of as much as 130 m³/h and a supply head of up to 57 m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of eight to 20 kW, a circulate rate of as much as 140 m³/h and a supply head of as a lot as 82 m are attainable. The suction cover mounted on the pump housing may also be used to adjust the cutting gap between the impeller and the damage plate with assistance from six set screws. “The energy of our new Alligator collection, which is on the market for moist nicely installation as properly as dry installation, is its nice effectivity and effective cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle costs thanks to wear-resistant design
In order to attain not solely the very best effectivity values within the working vary required for these kinds of wastewater applications, but also to scale back lifecycle prices general, HOMA attaches nice significance to low-maintenance operation along with efficiency. The impeller and wear plate, that are the elements subject to essentially the most stress, are manufactured from extremely sturdy chilled chrome cast iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics had been optimally designed for the operating range using computational fluid dynamics (CFD) to increase effectivity and to get rid of any chance of solids build up, which can negatively impact efficiency and result in costly pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids within the waste water and transport them away, saving both power and maintenance prices because of their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably appropriate for waste water purposes that require excessive supply pressure, however on the similar time need to take care of many alternative kinds of solids.”
HOMA will be presenting the brand new Alligator chopper pump sequence for the first time at IFAT 2022 in Munich. This and other improvements, similar to the maintenance slide with sliding motor mount, might be explained and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
