New chopper pump achieves excessive effectivity with out compromising on cutting efficiency

Problematic solids such as sanitary towels, plastic luggage, textiles and wood are being discovered increasingly typically 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 enjoying an ever extra essential function, HOMA Pumpenfabrik presents an vitality efficient and reliable solution for areas where a high supply head is required, however on the same time, a various vary of solids is anticipated: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator collection permits effective operation through a powerful cutter system. Thanks to using highly sturdy chilled chrome forged iron, the principle elements that are subject to probably the most stress carry out reliably even with abrasive substances similar to sand. HOMA might be presenting the model new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest attainable lifecycle prices are becoming more and more important in water and wastewater functions,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and dependable pumps that attain excessive delivery heads with great effectivity.” With its new Alligator chopper pump sequence, which will also be out there as an explosion-proof version, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with high efficiency
“Our aim was to attain excessive delivery pressures in the medium circulate fee vary,” stories Konstantin Pörsch. Without forfeiting เกรดวัดแรงดัน , the improved effectivity meant that a smaller, cheaper and more power saving motor than in other pumps in the same operating range was adequate. To obtain this, HOMA developed a new cutter system that successfully shreds and removes large portions of various solids such as tear-resistant hygiene wipes, plastic baggage and wood, which also get into the wastewater by way of surface water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the wear and tear plate, which can also be geared up with its personal cutter. This design permits the 2 central parts to work together to catch solids, break them down and ultimately take away them from the suction space through integrated grooves within the put on plate.
To enable larger efficiency with out compromising on chopping efficiency, the blades of the impeller additionally curve strongly backwards. As a end result, within the 50 Hz model, a circulate rate of as much as 130 m³/h and a supply head of as much as 57 m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of eight to twenty kW, a flow fee of as much as one hundred forty m³/h and a supply head of as much as eighty two m are possible. The suction cover mounted on the pump housing may additionally be used to regulate the slicing hole between the impeller and the put on and tear plate with assistance from six set screws. “The energy of our new Alligator series, which is on the market for wet well installation as well as dry installation, is its great effectivity and effective cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle prices due to wear-resistant design
In order to realize not only the finest possible effectivity values in the operating vary required for these sorts of wastewater applications, but additionally to reduce lifecycle costs general, HOMA attaches nice significance to low-maintenance operation along with efficiency. 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 such as sand in the pumped medium. In addition, the hydraulics had been optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to increase efficiency and to get rid of any possibility of solids increase, which may negatively influence performance and result in expensive 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 prices thanks to their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water purposes that require excessive supply pressure, but at the same time should take care of many different sorts of solids.”
HOMA will be presenting the new Alligator chopper pump collection for the primary time at IFAT 2022 in Munich. This and different innovations, such as the upkeep slide with sliding motor mount, might be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
