New chopper pump achieves excessive effectivity without compromising on cutting efficiency

Problematic solids corresponding to sanitary towels, plastic bags, textiles and wood are being found increasingly more usually in wastewater. Pumping and sewage remedy vegetation are therefore more and more reaching their limits; units get clogged up and break down.
In times when low lifecycle costs are enjoying an ever more important position, HOMA Pumpenfabrik offers an power environment friendly and reliable resolution for areas where a high delivery head is required, however on the identical time, a various range of solids is predicted: the Alligator chopper pump series. The newly developed OC impeller of the Alligator sequence allows effective operation by way of a strong cutter system. Thanks to the use of highly sturdy chilled chrome forged iron, the main components that are topic to the most stress perform reliably even with abrasive substances similar to sand. HOMA shall be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs have gotten increasingly important in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and reliable pumps that reach excessive supply heads with great efficiency.” With its new Alligator chopper pump sequence, which may also be obtainable as an explosion-proof model, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with high effectivity
“Our goal was to realize high supply pressures in the medium move price range,” reviews Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and extra power saving motor than in other pumps in the identical working vary was adequate. To achieve this, HOMA developed a brand new cutter system that effectively shreds and removes large quantities of diverse solids corresponding to tear-resistant hygiene wipes, plastic luggage and wood, which also get into the wastewater via floor water. nuova fima pressure gauge ราคา designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear and tear plate, which is also equipped with its own cutter. This design permits the two central elements to work together to catch solids, break them down and ultimately take away them from the suction area by way of built-in grooves in the wear plate.
To enable larger effectivity without compromising on chopping performance, the blades of the impeller also curve strongly backwards. As a outcome, within the 50 Hz version, a circulate fee of up to a 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 version, with power consumption of eight to twenty kW, a move fee of up to 140 m³/h and a delivery head of as much as eighty two m are attainable. The suction cover mounted on the pump housing can additionally be used to adjust the cutting gap between the impeller and the wear plate with the assist of six set screws. “The power of our new Alligator series, which is out there for moist well set up in addition to dry installation, is its nice efficiency and efficient cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to realize not solely the absolute best efficiency values within the operating vary required for these sorts of wastewater functions, but in addition to minimize back lifecycle prices total, HOMA attaches great importance to low-maintenance operation along with effectivity. The impeller and put on plate, that are the components subject to the most stress, are made of extraordinarily durable chilled chrome forged iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics had been optimally designed for the working vary utilizing computational fluid dynamics (CFD) to extend effectivity and to remove any possibility of solids build up, which can negatively impact 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 both vitality and maintenance prices because of their excessive efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water applications that require excessive delivery stress, however on the similar time need to deal with many alternative kinds of solids.”
HOMA shall be presenting the model new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and different 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.
