New chopper pump achieves high efficiency without compromising on cutting efficiency

Problematic solids corresponding to sanitary towels, plastic bags, textiles and wood are being found more and more usually in wastewater. Pumping and sewage therapy crops are therefore more and more reaching their limits; items get clogged up and break down.
In occasions when low lifecycle costs are enjoying an ever more necessary function, HOMA Pumpenfabrik provides an energy efficient and reliable resolution for areas the place a high supply head is required, however on the identical time, a diverse vary of solids is expected: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection allows efficient operation by way of a powerful cutter system. Thanks to the use of extremely sturdy chilled chrome forged iron, the primary elements which are topic 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.
“The lowest possible lifecycle prices have gotten more and more essential 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 energy saving and dependable pumps that attain high delivery heads with great effectivity.” With its new Alligator chopper pump collection, which will also be out there as an explosion-proof model, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our objective was to achieve excessive supply pressures in the medium move price range,” stories Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and extra energy saving motor than in other pumps in the identical working range was sufficient. To obtain this, HOMA developed a brand new cutter system that successfully shreds and removes large portions of various solids corresponding to tear-resistant hygiene wipes, plastic bags and wooden, which additionally 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 geared up with its own cutter. This design permits the 2 central parts to work together to catch solids, break them down and finally take away them from the suction space by way of built-in grooves within the put on plate.
To enable 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 as much as one hundred thirty m³/h and a supply head of as much as fifty seven m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of eight to twenty kW, a move rate of as much as 140 m³/h and a supply head of as much as eighty two m are possible. The suction cover mounted on the pump housing can be used to adjust the slicing gap between the impeller and the wear and tear plate with the help of six set screws. “The energy of our new Alligator series, which is out there for moist well set up in addition to dry set up, is its nice effectivity and effective cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to realize not solely the best possible effectivity values within the working range required for these kinds of wastewater functions, but in addition to scale back lifecycle prices total, HOMA attaches nice importance to low-maintenance operation in addition to effectivity. ที่วัดแรงดัน and put on plate, which are the elements topic to probably the most stress, are made from extremely durable chilled chrome forged iron, which withstands even abrasive substances such as sand within the pumped medium. In addition, the hydraulics were optimally designed for the operating range using computational fluid dynamics (CFD) to extend efficiency and to remove any risk of solids increase, which might negatively influence efficiency and result in pricey pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids within the waste water and transport them away, saving both power and maintenance costs thanks to their excessive efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water applications that require high delivery strain, however on the identical time have to deal with 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 maintenance slide with sliding motor mount, will be defined and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
