New chopper pump achieves excessive effectivity without compromising on slicing performance

Problematic solids such as sanitary towels, plastic bags, textiles and wooden are being found more and more usually in wastewater. Pumping and sewage remedy crops are due to this fact more and more reaching their limits; models get clogged up and break down.
In occasions when low lifecycle prices are playing an ever more necessary role, HOMA Pumpenfabrik provides an power environment friendly and reliable solution for areas where a excessive supply head is required, however on the same time, a various vary of solids is predicted: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator collection enables efficient operation by way of a powerful cutter system. Thanks to using extremely durable chilled chrome forged iron, the primary components which are subject to the most stress perform reliably even with abrasive substances similar to sand. HOMA will be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
เครื่องมือที่ใช้วัดความดันโลหิต are becoming more and more necessary 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 dependable pumps that attain excessive supply heads with great effectivity.” With its new Alligator chopper pump series, which may even be out there as an explosion-proof model, HOMA has developed a very environment friendly response to this demand.
Cutter system shreds all solids with high effectivity

“Our aim was to achieve excessive supply pressures in the medium circulate price range,” stories Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and extra power saving motor than in other pumps in the identical operating range was enough. To obtain this, HOMA developed a brand new cutter system that successfully shreds and removes massive quantities of various solids similar to tear-resistant hygiene wipes, plastic luggage and wood, which also get into the wastewater by way of floor water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which is also equipped with its personal cutter. This design allows the two central elements to work together to catch solids, break them down and finally remove them from the suction space via built-in grooves in the put on plate.
To enable higher effectivity without compromising on chopping efficiency, the blades of the impeller additionally curve strongly backwards. As a result, within the 50 Hz version, a circulate price of up to 130 m³/h and a delivery head of as much as fifty seven m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of 8 to twenty kW, a move price of as much as one hundred forty m³/h and a delivery head of as much as eighty two m are possible. The suction cover mounted on the pump housing can be used to regulate the slicing hole between the impeller and the wear plate with the help of six set screws. “The energy of our new Alligator collection, which is on the market for moist properly set up in addition to dry installation, is its nice efficiency and efficient cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design

In order to attain not solely the finest possible effectivity values in the working vary required for these sorts of wastewater functions, but additionally to scale back lifecycle costs general, HOMA attaches nice 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 from extremely sturdy chilled chrome cast iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics were optimally designed for the operating range utilizing computational fluid dynamics (CFD) to increase effectivity and to eliminate any risk of solids build up, which might negatively influence 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 each energy and maintenance prices thanks to their high efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water purposes that require high supply pressure, but at the similar time need to deal with many various kinds of solids.”

HOMA might be presenting the new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and other innovations, such as the upkeep slide with sliding motor mount, will be explained and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
