Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wood are being found more and more often in wastewater. Pumping and sewage treatment crops are therefore increasingly reaching their limits; items get clogged up and break down.
In occasions when low lifecycle costs are enjoying an ever more important role, HOMA Pumpenfabrik offers an vitality efficient and reliable resolution for areas the place a high delivery head is required, but at the similar time, a various vary of solids is expected: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator sequence permits effective operation via a powerful cutter system. Thanks to using highly sturdy chilled chrome cast iron, the main parts which might be subject to essentially the most stress perform reliably even with abrasive substances similar to sand. HOMA will be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs have gotten increasingly essential 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 vitality saving and reliable pumps that attain high delivery heads with nice efficiency.” With its new Alligator chopper pump series, which will also be available as an explosion-proof version, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our aim was to attain high supply pressures within the medium move rate range,” stories Konstantin Pörsch. Without forfeiting pump price, 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 achieve this, HOMA developed a model new cutter system that successfully shreds and removes massive portions of numerous solids similar to tear-resistant hygiene wipes, plastic bags and wood, which also get into the wastewater through 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 can additionally be outfitted with its own cutter. This design permits the two central parts to work collectively to catch solids, break them down and in the end take away them from the suction area by way of built-in grooves in the wear plate.
To allow greater efficiency without compromising on chopping performance, the blades of the impeller additionally curve strongly backwards. As a end result, within the 50 Hz version, a circulate fee of up to 130 m³/h and a supply head of as a lot as 57 m can be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of 8 to twenty kW, a circulate price of up to 140 m³/h and a supply head of up to 82 m are possible. The suction cover mounted on the pump housing may also be used to regulate the cutting hole between the impeller and the damage plate with the help of six set screws. “The power of our new Alligator series, which is out there for moist properly installation in addition to dry set up, is its great effectivity and efficient cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design
In order to attain not only the greatest possible effectivity values within the operating range required for these sorts of wastewater functions, but also to reduce lifecycle costs general, HOMA attaches great significance to low-maintenance operation along with effectivity. The impeller and wear plate, which are the elements subject to the most stress, are made from extremely durable chilled chrome cast iron, which withstands even abrasive substances such as sand within the pumped medium. In addition, the hydraulics were optimally designed for the operating range utilizing computational fluid dynamics (CFD) to increase efficiency and to remove any chance of solids increase, which might negatively impact 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 prices thanks to their high efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water purposes that require high delivery pressure, however on the similar time need to cope with many alternative sorts of solids.”
HOMA might be presenting pressure gauge ราคา for the primary time at IFAT 2022 in Munich. This and different improvements, similar to the maintenance slide with sliding motor mount, might be explained and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
