New chopper pump achieves high efficiency without compromising on slicing efficiency

Problematic solids such as sanitary towels, plastic baggage, textiles and wood are being discovered increasingly more typically in wastewater. Pumping and sewage treatment vegetation are due to this fact increasingly reaching their limits; items get clogged up and break down.
In เกจวัดแรงดันน้ำมันเบนซิน when low lifecycle prices are enjoying an ever extra important function, HOMA Pumpenfabrik offers an vitality efficient and dependable solution for areas where a excessive delivery head is required, but on the similar time, a diverse range of solids is expected: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator sequence allows efficient operation through a powerful cutter system. Thanks to the use of extremely sturdy chilled chrome forged iron, the primary elements which are topic to essentially the most stress perform reliably even with abrasive substances such as sand. HOMA will be presenting the new Alligator chopper pumps for the first 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 division at HOMA Pumpenfabrik GmbH. “There is a rising demand for power saving and dependable pumps that reach high supply heads with nice effectivity.” With its new Alligator chopper pump series, which may also be obtainable as an explosion-proof model, HOMA has developed a very environment friendly response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our aim was to realize excessive supply pressures within the medium flow rate vary,” reports Konstantin Pörsch. Without forfeiting pump fee, the improved efficiency meant that a smaller, cheaper and extra vitality saving motor than in other pumps in the identical operating range was enough. To obtain this, HOMA developed a model new cutter system that successfully shreds and removes large quantities of various solids corresponding to tear-resistant hygiene wipes, plastic baggage 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 wear and tear plate, which can be equipped with its own cutter. This design allows the two central elements to work together to catch solids, break them down and in the end remove them from the suction area through integrated grooves within the put on plate.
To allow larger effectivity with out compromising on chopping performance, the blades of the impeller also curve strongly backwards. As a end result, in the 50 Hz model, a circulate fee of up to 130 m³/h and a delivery head of up to 57 m could 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 fee of as much as one hundred forty m³/h and a supply head of as much as 82 m are possible. The suction cowl mounted on the pump housing can also be used to regulate the chopping gap between the impeller and the wear plate with the assist of six set screws. “The energy of our new Alligator sequence, which is available for moist nicely set up as nicely as dry installation, is its great effectivity and effective cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle costs because of wear-resistant design
In order to attain not solely the absolute best effectivity values within the operating vary required for these kinds of wastewater functions, but in addition to reduce lifecycle costs overall, HOMA attaches nice significance to low-maintenance operation along with effectivity. The impeller and put on plate, which are the components topic to probably the most stress, are made of extremely durable chilled chrome cast iron, which withstands even abrasive substances similar to sand in the pumped medium. In addition, the hydraulics have been optimally designed for the working vary utilizing computational fluid dynamics (CFD) to increase effectivity and to eliminate any possibility of solids increase, which might negatively influence performance and lead to costly 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 vitality and maintenance prices due to their high efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water applications that require high delivery pressure, but at the similar time should deal with many alternative sorts of solids.”
HOMA will be presenting the new Alligator chopper pump collection for the first time at IFAT 2022 in Munich. This and other innovations, similar to the upkeep slide with sliding motor mount, will be defined and demonstrated by the HOMA gross sales group in Hall B1 at Stand 429/528.
