Problematic solids similar to sanitary towels, plastic baggage, textiles and wood are being found increasingly often in wastewater. Pumping and sewage remedy plants are therefore more and more reaching their limits; units get clogged up and break down.
In occasions when low lifecycle costs are taking half in an ever extra essential position, HOMA Pumpenfabrik offers an energy environment friendly and reliable answer for areas where a excessive delivery head is required, but on the identical time, a diverse range of solids is expected: the Alligator chopper pump series. The newly developed OC impeller of the Alligator sequence allows efficient operation by way of a powerful cutter system. Thanks to using 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 might be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle prices have gotten more and more essential in water and wastewater applications,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and reliable pumps that reach high supply heads with nice effectivity.” With its new Alligator chopper pump sequence, which may also be available as an explosion-proof model, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with high effectivity
“Our goal was to attain excessive delivery pressures within the medium circulate fee vary,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and more vitality saving motor than in other pumps in the same working vary was enough. To obtain เกจ์วัดแรงดันลม , HOMA developed a brand new cutter system that effectively shreds and removes massive quantities of diverse solids corresponding to tear-resistant hygiene wipes, plastic baggage and wooden, which additionally get into the wastewater via surface water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear plate, which can also be equipped with its own cutter. This design permits the two central components to work collectively to catch solids, break them down and ultimately take away them from the suction space through integrated grooves in the put on plate.
To allow larger efficiency without compromising on cutting efficiency, the blades of the impeller additionally curve strongly backwards. As a end result, in the 50 Hz model, a circulate fee of up to a hundred thirty m³/h and a delivery head of up to fifty seven m can be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of eight to 20 kW, a flow rate of up to 140 m³/h and a supply head of as a lot as eighty two m are attainable. The suction cover mounted on the pump housing may additionally be used to regulate the cutting hole between the impeller and the wear and tear plate with the assist of six set screws. “The energy of our new Alligator sequence, which is on the market for wet well installation as properly as dry set up, is its nice efficiency and efficient cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to realize not only the very best efficiency values in the operating range required for these sorts of wastewater functions, but also to cut back lifecycle costs overall, HOMA attaches great significance to low-maintenance operation in addition to efficiency. The impeller and wear plate, that are the components topic to the most stress, are made from extremely durable chilled chrome cast iron, which withstands even abrasive substances similar to sand in the pumped medium. In addition, the hydraulics were optimally designed for the operating vary using computational fluid dynamics (CFD) to extend efficiency and to eliminate any possibility of solids build up, which may negatively influence performance and lead to 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 each vitality and maintenance costs thanks to their high efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water purposes that require excessive supply pressure, but on the similar time need to cope with many alternative sorts of solids.”
HOMA will be presenting the new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and other improvements, similar to the maintenance slide with sliding motor mount, shall be explained and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
