Problematic solids corresponding to sanitary towels, plastic bags, textiles and wood are being found more and more typically in wastewater. Pumping and sewage remedy crops are therefore more and more reaching their limits; items get clogged up and break down.
In occasions when low lifecycle costs are taking part in an ever more essential position, HOMA Pumpenfabrik offers an power environment friendly and dependable answer for areas where a excessive delivery head is required, but on the similar time, a diverse range of solids is predicted: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection allows effective operation via a strong cutter system. Thanks to the utilization of highly durable chilled chrome forged iron, the primary parts which may be subject to probably the most stress perform reliably even with abrasive substances corresponding to sand. HOMA will be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest possible lifecycle prices are becoming increasingly important in water and wastewater applications,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for vitality saving and dependable pumps that reach excessive supply heads with nice effectivity.” With its new Alligator chopper pump collection, which may even be obtainable 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 attain high supply pressures within the medium flow fee range,” stories Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and extra energy saving motor than in different pumps in the identical operating vary was adequate. To obtain this, HOMA developed a new cutter system that successfully shreds and removes massive portions of numerous solids such as tear-resistant hygiene wipes, plastic bags and wood, which additionally get into the wastewater through surface water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the put on and tear plate, which can be equipped with its personal cutter. This design allows the two central parts to work collectively to catch solids, break them down and ultimately remove them from the suction area through integrated grooves in the put on plate.
To allow higher efficiency without compromising on cutting efficiency, the blades of the impeller additionally curve strongly backwards. As a result, in the 50 Hz model, a flow fee of up to 130 m³/h and a supply head of up to fifty seven m can 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 rate of up to a hundred and forty m³/h and a supply head of as a lot as 82 m are possible. The suction cowl mounted on the pump housing can also be used to regulate the chopping hole between the impeller and the put on and tear plate with assistance from six set screws. “The power of our new Alligator collection, which is on the market for moist nicely installation in addition to dry installation, is its great effectivity and efficient cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design
In order to realize not only the very best efficiency values within the operating vary required for these kinds of wastewater applications, but in addition to reduce lifecycle prices general, HOMA attaches nice importance to low-maintenance operation in addition to effectivity. The impeller and put on plate, which are the parts topic to essentially the most stress, are made of extremely sturdy chilled chrome forged iron, which withstands even abrasive substances such as sand within the pumped medium. In เกจ์วัดแรงดัน , the hydraulics were optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to increase effectivity and to eliminate any possibility of solids build up, which might 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 power and upkeep prices due to their high effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them notably appropriate for waste water applications that require high supply stress, but on the similar time should deal with many alternative sorts of solids.”
HOMA will be presenting the new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and other innovations, such as the upkeep slide with sliding motor mount, might be defined and demonstrated by the HOMA gross sales group in Hall B1 at Stand 429/528.
