New chopper pump achieves high efficiency with out compromising on slicing performance

Problematic solids similar to sanitary towels, plastic luggage, textiles and wood are being discovered more and more typically in wastewater. Pumping and sewage treatment plants are due to this fact more and more reaching their limits; units get clogged up and break down.
In เกจวัดแรงกด when low lifecycle costs are enjoying an ever extra essential position, HOMA Pumpenfabrik offers an vitality environment friendly and dependable answer for areas the place a excessive supply head is required, but on the same time, a diverse vary of solids is predicted: the Alligator chopper pump series. The newly developed OC impeller of the Alligator sequence permits efficient operation through a powerful cutter system. Thanks to the use of extremely durable chilled chrome forged iron, the principle elements which are subject to probably the most stress perform reliably even with abrasive substances corresponding to sand. HOMA will be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs are becoming increasingly necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for energy saving and reliable pumps that reach high delivery heads with nice efficiency.” With its new Alligator chopper pump series, which may also be out there as an explosion-proof version, HOMA has developed a very environment friendly response to this demand.
Cutter system shreds all solids with excessive efficiency

“Our aim was to attain high supply pressures in the medium move fee vary,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and more vitality saving motor than in other pumps in the identical working range was sufficient. To achieve this, HOMA developed a new cutter system that successfully shreds and removes large quantities of various solids such as tear-resistant hygiene wipes, plastic luggage and wooden, which also get into the wastewater by way of floor water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the wear and tear plate, which can also be outfitted with its personal cutter. This design permits the 2 central components to work together to catch solids, break them down and finally remove them from the suction space through integrated grooves within the wear plate.
To allow greater effectivity with out compromising on chopping performance, the blades of the impeller also curve strongly backwards. As a outcome, in the 50 Hz model, a flow rate of as much as one hundred thirty m³/h and a supply head of up to 57 m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of 8 to twenty kW, a move fee of as a lot as 140 m³/h and a delivery head of up to 82 m are possible. The suction cover mounted on the pump housing may also be used to adjust the slicing hole between the impeller and the put on and tear plate with the assist of six set screws. “The power of our new Alligator series, which is on the market for wet well set up in addition to dry set up, is its nice efficiency and effective cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design

In order to achieve not only the absolute best effectivity values in the working range required for these kinds of wastewater applications, but also to cut back lifecycle costs total, HOMA attaches nice importance to low-maintenance operation in addition to effectivity. The impeller and put on plate, which are the elements subject to essentially the most stress, are made from extraordinarily durable chilled chrome cast iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics were optimally designed for the working vary using computational fluid dynamics (CFD) to increase effectivity and to eliminate any possibility of solids build up, which can negatively impact performance and lead to pricey 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 vitality and maintenance costs due to their excessive efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water purposes that require high delivery pressure, but on the similar time should cope with many different kinds of solids.”

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