New chopper pump achieves excessive effectivity without compromising on cutting performance

Problematic solids such as sanitary towels, plastic baggage, textiles and wooden are being discovered increasingly more usually in wastewater. Pumping and pressure gauge ด้าน ดูด are therefore more and more reaching their limits; units get clogged up and break down.
In instances when low lifecycle costs are playing an ever more important position, HOMA Pumpenfabrik provides an energy environment friendly and dependable resolution for areas where a high supply head is required, however at the similar time, a various range of solids is expected: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator collection permits effective operation by way of a powerful cutter system. Thanks to the usage of extremely durable chilled chrome cast iron, the primary elements which would possibly be subject to the most stress perform reliably even with abrasive substances corresponding to sand. HOMA shall be presenting the model new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest attainable lifecycle prices are becoming more and more necessary in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for power saving and reliable pumps that attain high supply heads with great efficiency.” With its new Alligator chopper pump sequence, which may even be available as an explosion-proof version, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our aim was to attain high delivery pressures in the medium move fee vary,” stories Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and extra vitality saving motor than in different pumps in the same working range was adequate. To achieve this, HOMA developed a new cutter system that successfully shreds and removes massive portions of numerous solids corresponding to tear-resistant hygiene wipes, plastic luggage and wood, which additionally 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 plate, which is also geared up with its personal cutter. This design allows the two central elements to work together to catch solids, break them down and ultimately take away them from the suction area via built-in grooves within the put on plate.
To enable higher efficiency with out compromising on chopping efficiency, the blades of the impeller additionally curve strongly backwards. As a result, within the 50 Hz model, a circulate rate of as much as 130 m³/h and a delivery head of up to 57 m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of eight to 20 kW, a flow rate of as much as 140 m³/h and a supply head of as much as eighty two m are attainable. The suction cowl mounted on the pump housing can additionally be used to regulate the slicing hole between the impeller and the wear plate with assistance from six set screws. “The power of our new Alligator collection, which is out there for wet nicely installation as nicely as dry installation, is its great efficiency and efficient cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle prices due to wear-resistant design
In order to realize not solely the very best effectivity values within the operating range required for these kinds of wastewater applications, but also to scale back lifecycle prices total, HOMA attaches great significance to low-maintenance operation along with efficiency. The impeller and wear plate, that are the parts subject to the most stress, are manufactured from extraordinarily durable chilled chrome forged iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics have been optimally designed for the operating range using computational fluid dynamics (CFD) to increase effectivity and to eliminate any risk of solids increase, which might negatively influence performance and result in 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 energy and upkeep prices because of their excessive efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water applications that require high delivery stress, but on the same time need to take care of many various sorts of solids.”
HOMA might be presenting the brand new Alligator chopper pump collection for the first time at IFAT 2022 in Munich. This and different improvements, similar to the upkeep slide with sliding motor mount, might be explained and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
