Problematic solids similar to sanitary towels, plastic luggage, textiles and wooden are being found increasingly typically in wastewater. Pumping and sewage remedy crops are due to this fact increasingly reaching their limits; models get clogged up and break down.
In occasions when low lifecycle costs are taking half in an ever extra essential role, HOMA Pumpenfabrik offers an energy environment friendly and dependable resolution for areas the place a high supply head is required, but at the identical time, a diverse range of solids is expected: the Alligator chopper pump series. The newly developed OC impeller of the Alligator series permits efficient operation via a powerful cutter system. Thanks to the use of highly sturdy chilled chrome forged iron, the principle parts that are topic to the most stress perform reliably even with abrasive substances similar to sand. HOMA shall be presenting เกจวัดแรงดันแก๊สlpg for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs have gotten more and more essential in water and wastewater functions,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for power saving and reliable pumps that attain high supply heads with great effectivity.” With its new Alligator chopper pump sequence, which will also be available as an explosion-proof version, HOMA has developed a very environment friendly response to this demand.
Cutter system shreds all solids with high effectivity
“Our aim was to realize excessive delivery pressures within the medium circulate fee vary,” reviews Konstantin Pörsch. Without forfeiting pump fee, the improved efficiency meant that a smaller, cheaper and extra power saving motor than in other pumps in the identical operating vary was sufficient. To achieve this, HOMA developed a brand new cutter system that successfully shreds and removes giant portions of numerous solids similar to tear-resistant hygiene wipes, plastic luggage and wooden, which additionally get into the wastewater via surface water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which can be geared up with its personal cutter. This design permits the two central components to work together to catch solids, break them down and finally remove them from the suction area via integrated grooves within the put on plate.
To enable higher effectivity with out compromising on cutting efficiency, the blades of the impeller additionally curve strongly backwards. As a result, in the 50 Hz version, a circulate fee of as a lot as 130 m³/h and a delivery head of up to fifty seven m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of eight to twenty kW, a flow fee of up to one hundred forty m³/h and a delivery head of as much as eighty two m are possible. The suction cowl mounted on the pump housing may also be used to regulate the slicing hole between the impeller and the wear plate with the assist of six set screws. “The power of our new Alligator sequence, which is out there for moist nicely installation in addition to dry set up, is its nice efficiency and efficient cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to attain not solely the absolute best effectivity values in the operating vary required for these sorts of wastewater purposes, but in addition to cut back lifecycle prices overall, HOMA attaches nice significance to low-maintenance operation along with efficiency. The impeller and put on plate, which are the components topic to essentially the most stress, are manufactured from extraordinarily sturdy chilled chrome cast iron, which withstands even abrasive substances similar to sand within the pumped medium. In addition, the hydraulics have been optimally designed for the operating range utilizing computational fluid dynamics (CFD) to extend effectivity and to remove any chance of solids build up, which may negatively impression efficiency and lead to costly 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 vitality and upkeep costs due to their high effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water purposes that require high delivery pressure, but on the identical time should take care of many different sorts of solids.”
HOMA shall be presenting the new Alligator chopper pump sequence for the first time at IFAT 2022 in Munich. This and different innovations, similar to the maintenance slide with sliding motor mount, might be explained and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
