New chopper pump achieves excessive efficiency with out compromising on chopping efficiency

Problematic solids similar to sanitary towels, plastic bags, textiles and wooden are being discovered more and more often in wastewater. Pumping and sewage remedy plants are therefore increasingly reaching their limits; models get clogged up and break down.
In times when low lifecycle costs are taking part in an ever more necessary role, HOMA Pumpenfabrik offers an vitality environment friendly and reliable solution for areas where a excessive supply head is required, but at the similar time, a diverse vary of solids is expected: the Alligator chopper pump series. The newly developed OC impeller of the Alligator sequence allows effective operation via a powerful cutter system. Thanks to the usage of highly sturdy chilled chrome cast iron, the main components which may be subject to probably the most stress perform reliably even with abrasive substances corresponding to sand. HOMA might be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle prices have gotten increasingly necessary in water and wastewater functions,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for power saving and dependable pumps that attain high delivery heads with great effectivity.” With pressure gauge weksler ราคา , which may also be obtainable as an explosion-proof version, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with high efficiency

“Our objective was to achieve high supply pressures in the medium move price vary,” reviews Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and extra energy saving motor than in other pumps in the identical working vary was adequate. To obtain this, HOMA developed a new cutter system that effectively shreds and removes giant quantities of various solids similar to tear-resistant hygiene wipes, plastic luggage and wooden, which additionally get into the wastewater via floor water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the put on and tear plate, which is also outfitted with its personal cutter. This design allows the two central parts to work together to catch solids, break them down and finally take away them from the suction space via built-in grooves within the wear plate.
To allow larger effectivity with out compromising on cutting efficiency, the blades of the impeller also curve strongly backwards. As a outcome, in the 50 Hz version, a move price of as a lot as a 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 energy consumption of eight to 20 kW, a circulate fee of as a lot as one hundred forty m³/h and a supply head of as a lot as 82 m are attainable. The suction cowl mounted on the pump housing may additionally be used to regulate the slicing gap between the impeller and the wear plate with assistance from six set screws. “The power of our new Alligator sequence, which is out there for moist nicely installation as properly as dry installation, is its nice effectivity and effective cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design

In order to attain not only the very best efficiency values within the operating vary required for these kinds of wastewater functions, but in addition to scale back lifecycle costs overall, HOMA attaches great importance to low-maintenance operation along with effectivity. The impeller and put on plate, that are the elements subject to probably the most stress, are made from extraordinarily sturdy chilled chrome forged iron, which withstands even abrasive substances corresponding to sand within the pumped medium. In addition, the hydraulics were optimally designed for the working range using computational fluid dynamics (CFD) to increase effectivity and to remove any risk of solids increase, which might negatively influence efficiency and lead to pricey pump failures. “With the newly developed cutter system, the Alligator pumps can successfully break down all solids within the waste water and transport them away, saving both power and upkeep costs due to their excessive efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water functions that require high delivery strain, but on the same time have to take care of many various kinds of solids.”

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