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

Problematic solids similar to sanitary towels, plastic bags, textiles and wood are being found more and more typically in wastewater. Pumping and sewage remedy plants are due to this fact more and more reaching their limits; models get clogged up and break down.
In occasions when low lifecycle costs are enjoying an ever extra important position, HOMA Pumpenfabrik presents an energy efficient and dependable solution for areas the place a excessive delivery head is required, however on the similar time, a diverse range of solids is expected: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator series permits efficient operation through a powerful cutter system. Thanks to using extremely durable chilled chrome cast iron, the principle parts which would possibly be subject to probably the most stress perform reliably even with abrasive substances similar to sand. HOMA might be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest potential lifecycle prices have gotten more and more necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is ราคาเกจวัดแรงดันลม rising demand for energy saving and dependable pumps that reach excessive delivery heads with nice efficiency.” With its new Alligator chopper pump sequence, which will also be obtainable as an explosion-proof model, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with high efficiency
“Our objective was to realize excessive delivery pressures within the medium circulate price range,” stories Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and more power saving motor than in other pumps in the identical working range was adequate. To obtain this, HOMA developed a new cutter system that effectively shreds and removes massive quantities of diverse solids similar to tear-resistant hygiene wipes, plastic bags and wood, which additionally get into the wastewater through floor water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear plate, which can additionally be geared up with its personal cutter. This design allows the 2 central components to work together to catch solids, break them down and in the end remove them from the suction space through built-in grooves in the put on plate.
To allow larger effectivity with out compromising on chopping efficiency, the blades of the impeller also curve strongly backwards. As a end result, in the 50 Hz model, a circulate fee of as a lot as one hundred thirty m³/h and a supply head of up to fifty seven m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of eight to 20 kW, a circulate rate of up to one hundred forty m³/h and a supply head of up to 82 m are potential. The suction cowl mounted on the pump housing can be used to adjust the slicing gap between the impeller and the damage plate with the help of six set screws. “The energy of our new Alligator sequence, which is on the market for moist well set up in addition to dry set up, is its great effectivity and effective cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle prices due to wear-resistant design
In order to attain not solely the very best efficiency values within the operating range required for these sorts of wastewater functions, but also to reduce back lifecycle costs overall, HOMA attaches great significance to low-maintenance operation along with effectivity. The impeller and wear plate, which are the elements topic 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 operating vary using computational fluid dynamics (CFD) to increase efficiency and to get rid of any risk of solids building up, which might negatively influence efficiency and lead to 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 both energy and upkeep costs thanks to their excessive efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water purposes that require excessive delivery strain, however at the same time have to cope with many different kinds of solids.”
HOMA might be presenting the new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and different improvements, corresponding to the upkeep slide with sliding motor mount, shall be defined and demonstrated by the HOMA sales group in Hall B1 at Stand 429/528.
