New chopper pump achieves excessive effectivity without compromising on slicing performance

Problematic solids similar to sanitary towels, plastic bags, textiles and wood are being found increasingly typically in wastewater. Pumping and sewage remedy vegetation are therefore more and more reaching their limits; items get clogged up and break down.
In occasions when low lifecycle costs are playing an ever extra important function, HOMA Pumpenfabrik provides an power environment friendly and reliable answer for areas where a excessive delivery head is required, but at the identical time, a diverse vary of solids is anticipated: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator series enables efficient operation by way of a powerful cutter system. Thanks to using extremely durable chilled chrome cast iron, the principle parts which are topic to essentially the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA will be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle prices have gotten increasingly 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 energy saving and dependable pumps that reach excessive delivery heads with great effectivity.” With its new Alligator chopper pump collection, 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 effectivity
“Our aim was to attain excessive supply pressures in the medium move price vary,” reports Konstantin Pörsch. Without forfeiting pump fee, the improved efficiency meant that a smaller, cheaper and more vitality saving motor than in different pumps in the same working range was enough. To obtain this, HOMA developed a brand new cutter system that successfully shreds and removes giant portions of various solids corresponding to tear-resistant hygiene wipes, plastic bags and wooden, which additionally get into the wastewater via surface water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the put on and tear plate, which is also equipped with its personal cutter. This design allows the 2 central components to work together to catch solids, break them down and finally take away them from the suction area via integrated grooves within the wear plate.
To enable higher effectivity with out compromising on cutting performance, the blades of the impeller also curve strongly backwards. As a end result, within the 50 Hz model, a circulate price of as much as one hundred thirty m³/h and a supply head of as a lot as fifty seven m can be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of eight to twenty kW, a move fee of up to 140 m³/h and a supply head of as a lot as eighty two m are potential. The suction cowl mounted on the pump housing can additionally be used to regulate the cutting gap between the impeller and the wear plate with the aid of six set screws. “The power of our new Alligator collection, which is available for moist properly set up in addition to dry installation, is its great effectivity and efficient cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to achieve not solely the best possible effectivity values in the operating range required for these sorts of wastewater functions, but additionally to reduce lifecycle costs general, HOMA attaches great importance to low-maintenance operation in addition to effectivity. pressure gauge ออก หลัง and put on plate, which are the components topic to the most stress, are manufactured from extremely sturdy chilled chrome cast iron, which withstands even abrasive substances similar to sand within the pumped medium. In addition, the hydraulics had been optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to extend effectivity and to remove any possibility of solids build up, which might negatively influence performance and lead to pricey 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 power and upkeep costs because of their excessive effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water applications that require high supply stress, but on the similar time have to cope with many various sorts of solids.”
HOMA shall 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, will be defined and demonstrated by the HOMA gross sales staff in Hall B1 at Stand 429/528.
