New chopper pump achieves excessive effectivity with out compromising on slicing efficiency

Problematic solids corresponding to sanitary towels, plastic bags, textiles and wooden are being discovered more and 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 times when low lifecycle prices are playing an ever more important position, HOMA Pumpenfabrik presents an power efficient and reliable solution for areas the place a excessive delivery head is required, but at the similar time, a various range of solids is expected: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator series allows effective operation by way of a powerful cutter system. Thanks to the usage of highly sturdy chilled chrome forged iron, the main elements which may be subject to probably the most stress perform reliably even with abrasive substances similar to sand. HOMA shall be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs have gotten more and more important in water and wastewater functions,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for power saving and reliable pumps that reach excessive delivery heads with great efficiency.” With ไดอะแฟรม ซีล , which will also be available as an explosion-proof model, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with high effectivity

“Our goal was to realize high supply pressures in the medium flow fee vary,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and extra power saving motor than in other pumps in the identical working range was enough. To obtain pressure gauge , HOMA developed a new cutter system that successfully shreds and removes giant quantities of diverse solids corresponding to tear-resistant hygiene wipes, plastic luggage and wood, which additionally get into the wastewater via surface water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which is also outfitted with its own cutter. This design permits the 2 central components to work together to catch solids, break them down and finally take away them from the suction space via built-in grooves in the wear plate.
To enable greater efficiency without compromising on chopping performance, the blades of the impeller also curve strongly backwards. As a end result, in the 50 Hz version, a circulate fee of up to 130 m³/h and a supply head of as much as 57 m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of eight to twenty kW, a circulate price of as much as a hundred and forty m³/h and a delivery head of up to eighty two m are potential. The suction cover mounted on the pump housing can additionally be used to adjust the slicing gap between the impeller and the damage plate with the assist of six set screws. “The strength of our new Alligator collection, which is out there for moist well installation as properly as dry installation, is its nice effectivity and efficient cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design

In order to realize not solely the best possible effectivity values in the operating range required for these kinds of wastewater purposes, but also to reduce lifecycle costs general, HOMA attaches great importance to low-maintenance operation in addition to effectivity. The impeller and put on plate, which are the components subject to essentially the most stress, are made of extremely sturdy chilled chrome cast iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics have been optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to increase efficiency and to get rid of any chance of solids increase, which can negatively influence 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 upkeep prices thanks to their excessive effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them notably appropriate for waste water applications that require high supply strain, however at the similar time should cope with many alternative kinds of solids.”

HOMA will be presenting the brand new Alligator chopper pump collection for the primary time at IFAT 2022 in Munich. This and different innovations, such as the upkeep slide with sliding motor mount, might be defined and demonstrated by the HOMA gross sales staff in Hall B1 at Stand 429/528.
