New chopper pump achieves high efficiency without compromising on slicing performance

เกจ์วัดแรงดัน to sanitary towels, plastic bags, textiles and wooden are being discovered more and more 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 occasions when low lifecycle costs are taking half in an ever extra essential function, HOMA Pumpenfabrik offers an power environment friendly and dependable answer for areas where a high supply head is required, however at the same time, a various range of solids is expected: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection permits efficient operation via a strong cutter system. Thanks to the usage of highly sturdy chilled chrome forged iron, the primary parts that are subject to essentially the most stress perform reliably even with abrasive substances corresponding to sand. HOMA will be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs are becoming increasingly necessary in water and wastewater functions,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and reliable pumps that attain high delivery heads with great effectivity.” With its new Alligator chopper pump sequence, which will 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 excessive efficiency
“Our aim was to achieve excessive supply pressures within the medium flow rate vary,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and extra power saving motor than in different pumps in the same operating vary was adequate. To obtain this, HOMA developed a brand new cutter system that successfully shreds and removes large quantities of diverse solids similar to tear-resistant hygiene wipes, plastic luggage and wooden, which additionally get into the wastewater via surface water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which is also equipped with its personal cutter. This design permits the two central elements 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 enable higher efficiency with out compromising on slicing performance, the blades of the impeller also curve strongly backwards. As a result, within the 50 Hz model, a flow fee of up to 130 m³/h and a supply head of as a lot as 57 m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of eight to 20 kW, a move price of up to 140 m³/h and a delivery head of up to 82 m are attainable. The suction cover mounted on the pump housing can also be used to regulate the cutting hole between the impeller and the put on and tear plate with the aid of six set screws. “The energy of our new Alligator sequence, which is available for moist nicely set up as properly as dry installation, is its nice efficiency and effective cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to realize not solely the very best efficiency values within the working range required for these kinds of wastewater purposes, but in addition to scale back lifecycle costs total, HOMA attaches nice significance to low-maintenance operation in addition to effectivity. The impeller and put on plate, that are the elements subject to essentially the most stress, are made of extremely sturdy 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 vary using computational fluid dynamics (CFD) to extend efficiency and to get rid of any risk of solids build up, which can negatively impact performance and result in expensive 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 each vitality and maintenance costs because of their excessive effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them notably appropriate for waste water purposes that require high supply pressure, however on the similar time need to cope with many different sorts of solids.”
HOMA shall be presenting the new Alligator chopper pump series for the primary time at IFAT 2022 in Munich. This and different innovations, corresponding to the upkeep slide with sliding motor mount, shall be explained and demonstrated by the HOMA sales group in Hall B1 at Stand 429/528.
