New chopper pump achieves high effectivity without compromising on chopping performance

Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wood are being discovered 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 times when low lifecycle costs are playing an ever extra important position, HOMA Pumpenfabrik presents an power environment friendly and dependable answer for areas where a high delivery head is required, but at the similar time, a diverse range of solids is predicted: the Alligator chopper pump series. The newly developed OC impeller of the Alligator series enables effective operation by way of a powerful cutter system. Thanks to using highly sturdy chilled chrome cast iron, the main components which are subject to essentially the most stress perform reliably even with abrasive substances such as sand. HOMA will be presenting the brand new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle prices have gotten more and more necessary in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for vitality saving and reliable pumps that attain high delivery heads with great effectivity.” With its new Alligator chopper pump collection, which may even 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 high efficiency

“Our goal was to attain excessive supply pressures in the medium circulate fee vary,” reports Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and extra power saving motor than in different pumps in the identical working range was adequate. To obtain this, HOMA developed a brand new cutter system that effectively shreds and removes giant quantities of numerous solids such as tear-resistant hygiene wipes, plastic bags and wood, which additionally get into the wastewater via floor water. เพรสเชอร์เกจ designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear plate, which can additionally be outfitted with its own cutter. This design allows the two central parts to work collectively to catch solids, break them down and in the end remove them from the suction space via integrated grooves in the wear plate.
To enable greater effectivity with out compromising on cutting efficiency, the blades of the impeller additionally curve strongly backwards. As a result, in the 50 Hz model, a move rate of as a lot as a hundred thirty m³/h and a supply head of up to fifty seven m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of 8 to twenty kW, a flow fee of up to a hundred and forty m³/h and a supply head of as a lot as 82 m are attainable. The suction cover mounted on the pump housing can additionally be used to regulate the cutting hole between the impeller and the damage plate with assistance from six set screws. “The strength of our new Alligator series, which is available for wet nicely set up in addition to dry set up, is its great efficiency and efficient cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design

In order to attain not only the very best efficiency values within the operating range required for these kinds of wastewater purposes, but also to reduce lifecycle costs overall, HOMA attaches great importance to low-maintenance operation along with effectivity. The impeller and put on plate, which are the components subject to probably the most stress, are manufactured from extremely sturdy chilled chrome cast iron, which withstands even abrasive substances corresponding to sand within the pumped medium. In addition, the hydraulics were optimally designed for the operating vary using computational fluid dynamics (CFD) to increase effectivity and to eliminate any chance of solids building up, which might negatively influence efficiency and lead to pricey pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids in the waste water and transport them away, saving each vitality and maintenance costs because of their excessive efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water functions that require excessive supply strain, however at the same time need to cope with many different kinds of solids.”

HOMA shall be presenting the new Alligator chopper pump collection for the primary time at IFAT 2022 in Munich. This and other improvements, similar to the upkeep slide with sliding motor mount, might be defined and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
