Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wood are being found increasingly typically in wastewater. Pumping and sewage therapy vegetation are subsequently more and more reaching their limits; units get clogged up and break down.
In เพรสเชอร์เกจ when low lifecycle costs are playing an ever extra essential role, HOMA Pumpenfabrik presents an energy environment friendly and dependable resolution for areas where a high supply head is required, but at the similar time, a various range of solids is predicted: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator collection enables effective operation through a powerful cutter system. Thanks to the use of extremely durable chilled chrome forged iron, the main parts that are topic to the most stress carry out reliably even with abrasive substances such as sand. HOMA will be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs are becoming more and more important in water and wastewater functions,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for vitality saving and reliable pumps that attain high delivery heads with great efficiency.” With its new Alligator chopper pump collection, which will also be available as an explosion-proof model, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with high effectivity
“Our goal was to achieve high supply pressures in the medium move rate vary,” 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 identical operating range was sufficient. To obtain this, HOMA developed a new cutter system that effectively shreds and removes massive quantities of numerous solids corresponding to tear-resistant hygiene wipes, plastic baggage and wood, which also get into the wastewater through floor water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear and tear plate, which can also be outfitted with its own cutter. This design allows the two central components to work together to catch solids, break them down and ultimately remove them from the suction area via built-in grooves within the wear plate.
To allow higher effectivity with out compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a outcome, in the 50 Hz version, a flow rate of up to 130 m³/h and a supply head of as much as 57 m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of eight to 20 kW, a circulate price of up to a hundred and forty m³/h and a delivery head of as much as eighty two m are attainable. The suction cover mounted on the pump housing may additionally be used to adjust the cutting hole between the impeller and the put on and tear plate with assistance from six set screws. “The strength of our new Alligator collection, which is out there for wet properly set up as nicely as dry set up, is its nice effectivity and effective cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to achieve not only the finest possible efficiency values in the working vary required for these sorts of wastewater applications, but also to reduce lifecycle costs general, HOMA attaches great significance to low-maintenance operation in addition to effectivity. The impeller and wear plate, which are the components topic to the most stress, are made from extremely durable chilled chrome cast iron, which withstands even abrasive substances corresponding to sand within the pumped medium. In ไดอะแฟรม , the hydraulics have been optimally designed for the working vary using computational fluid dynamics (CFD) to increase efficiency and to get rid of any possibility of solids building up, which may negatively influence efficiency and lead to 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 each power and maintenance costs due to their excessive efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water functions that require high supply strain, however on the same time should cope with many various sorts of solids.”
HOMA shall be presenting the brand 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.
