Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wood are being discovered increasingly more typically in wastewater. Pumping and sewage treatment plants are subsequently increasingly reaching their limits; models get clogged up and break down.
In occasions when low lifecycle prices are taking half in an ever more important role, HOMA Pumpenfabrik offers an energy efficient and reliable answer for areas the place a excessive supply head is required, but on the identical time, a diverse range of solids is expected: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator sequence allows efficient operation by way of a strong cutter system. Thanks to the utilization of extremely sturdy chilled chrome cast iron, the principle elements which may be topic to probably the most stress carry out 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.
“ เพรสเชอร์เกจวัดแรงดันน้ำ are becoming increasingly necessary 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 reliable pumps that attain high delivery heads with nice efficiency.” With its new Alligator chopper pump series, which may even be available as an explosion-proof model, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with high effectivity
“Our goal was to attain excessive supply pressures in the medium circulate rate vary,” reviews Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and extra vitality saving motor than in other pumps in the same operating vary was adequate. To achieve this, HOMA developed a brand new cutter system that successfully shreds and removes massive portions of diverse solids corresponding to tear-resistant hygiene wipes, plastic bags and wood, which also get into the wastewater through surface water. The specially designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the wear plate, which can be geared up with its own cutter. This design allows the 2 central parts to work together to catch solids, break them down and ultimately take away them from the suction space via integrated grooves within the wear plate.
To enable greater efficiency with out compromising on chopping performance, the blades of the impeller also curve strongly backwards. As a outcome, within the 50 Hz model, a flow fee of as a lot as a hundred thirty m³/h and a supply head of as a lot as 57 m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of eight to 20 kW, a circulate fee of up to one hundred forty m³/h and a supply head of as much as eighty two m are possible. The suction cowl mounted on the pump housing can additionally be used to adjust the cutting gap between the impeller and the wear plate with assistance from six set screws. “The power of our new Alligator collection, which is on the market for wet properly installation in addition to dry set up, is its great efficiency and effective cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to achieve not only the very best efficiency values within the working range required for these kinds of wastewater purposes, but also to minimize back lifecycle prices total, HOMA attaches great significance to low-maintenance operation along with efficiency. The impeller and put on plate, that are the elements topic to the most stress, are made of extremely sturdy chilled chrome forged iron, which withstands even abrasive substances corresponding to sand within the pumped medium. In addition, the hydraulics have been optimally designed for the working range using computational fluid dynamics (CFD) to extend efficiency and to get rid of any possibility of solids build up, which can negatively influence performance and lead to pricey 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 both power and maintenance costs because of their excessive efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water applications that require high supply strain, however at the similar time have to take care of many various sorts of solids.”
HOMA will be presenting the new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and different innovations, similar to the maintenance slide with sliding motor mount, will be defined and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
