Problematic solids such as sanitary towels, plastic luggage, textiles and wooden are being found increasingly more usually in wastewater. Pumping and เกจวัดแรงดันน้ำดิจิตอล are therefore increasingly reaching their limits; models get clogged up and break down.
In instances when low lifecycle prices are taking half in an ever more necessary function, HOMA Pumpenfabrik presents an power efficient and reliable answer for areas where a excessive delivery head is required, however at the same time, a various vary of solids is expected: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator series enables effective operation by way of a robust cutter system. Thanks to using extremely sturdy chilled chrome forged iron, the principle parts that are topic to the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA will be presenting the brand new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle prices have gotten more and more necessary in water and wastewater functions,” 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 attain high delivery heads with great effectivity.” With its new Alligator chopper pump series, which may also be out there 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 goal was to achieve excessive delivery pressures in the medium flow price range,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and extra vitality saving motor than in different pumps in the same working range was enough. To obtain เกจแรงดัน , HOMA developed a model new cutter system that successfully shreds and removes large quantities of various solids corresponding to tear-resistant hygiene wipes, plastic luggage and wooden, which additionally get into the wastewater through floor water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear plate, which can be equipped with its personal cutter. This design permits the 2 central parts to work together to catch solids, break them down and in the end take away them from the suction area through built-in grooves in the put on plate.
To enable greater efficiency with out compromising on chopping efficiency, the blades of the impeller additionally curve strongly backwards. As a end result, in the 50 Hz model, a move rate of as much as one hundred thirty m³/h and a supply head of as a lot as 57 m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of 8 to 20 kW, a circulate rate of up to one hundred forty m³/h and a supply head of up to eighty two m are potential. The suction cowl mounted on the pump housing can also be used to regulate the cutting hole between the impeller and the wear plate with the help of six set screws. “The power of our new Alligator series, which is on the market for wet nicely set up as nicely as dry installation, is its great efficiency and effective cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle costs because of wear-resistant design
In order to realize not solely the absolute best efficiency values within the working vary required for these kinds of wastewater applications, but also to reduce back lifecycle prices overall, HOMA attaches great importance to low-maintenance operation along with effectivity. The impeller and put on plate, that are the components subject to essentially the most stress, are made of extraordinarily sturdy chilled chrome forged iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics had been optimally designed for the operating range using computational fluid dynamics (CFD) to extend effectivity and to remove any chance of solids build up, which can negatively influence performance and result in 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 effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water applications that require high delivery strain, but on the similar time should deal with many different sorts of solids.”
HOMA shall be presenting the new Alligator chopper pump collection for the first time at IFAT 2022 in Munich. This and other innovations, similar to the upkeep slide with sliding motor mount, shall be defined and demonstrated by the HOMA gross sales staff in Hall B1 at Stand 429/528.
