New chopper pump achieves high efficiency with out compromising on cutting performance

Problematic solids similar to sanitary towels, plastic bags, textiles and wooden are being discovered increasingly more usually in wastewater. Pumping and sewage treatment crops are due to this fact more and more reaching their limits; items get clogged up and break down.
In occasions when low lifecycle prices are enjoying an ever more important position, HOMA Pumpenfabrik offers an power environment friendly and dependable resolution for areas the place a excessive supply head is required, however on the same time, a various range of solids is anticipated: the Alligator chopper pump series. The newly developed OC impeller of the Alligator series allows efficient operation by way of a robust cutter system. Thanks to using extremely sturdy chilled chrome cast iron, the main elements which are subject to probably the most stress perform 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 attainable lifecycle prices have gotten more and more essential in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for power saving and dependable pumps that reach high supply heads with nice efficiency.” With เกจวัดแรงดัน300psi , which may even be out there as an explosion-proof version, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with high effectivity
“Our aim was to achieve excessive delivery pressures in the medium move fee range,” reports 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 vary was sufficient. To obtain this, HOMA developed a new cutter system that successfully shreds and removes large quantities of diverse solids similar to tear-resistant hygiene wipes, plastic baggage and wood, which also get into the wastewater via floor water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear and tear plate, which is also equipped with its own cutter. This design permits the 2 central elements to work collectively to catch solids, break them down and ultimately take away them from the suction area via built-in grooves in the wear plate.
To enable higher effectivity with out compromising on slicing performance, the blades of the impeller also curve strongly backwards. As a outcome, within the 50 Hz model, a move rate of up to one hundred thirty m³/h and a supply head of up to fifty seven m can be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of 8 to 20 kW, a move rate of up to a hundred and 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 be used to regulate the chopping hole between the impeller and the wear plate with the assist of six set screws. “The energy of our new Alligator collection, which is out there for wet properly installation in addition to dry set up, is its nice effectivity and efficient cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle costs thanks to wear-resistant design
In order to realize not solely the very best effectivity values within the working range required for these sorts of wastewater purposes, but additionally to reduce lifecycle prices general, HOMA attaches nice significance to low-maintenance operation in addition to effectivity. The impeller and put on plate, that are the components topic to the most stress, are manufactured from extraordinarily sturdy chilled chrome forged iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics have been optimally designed for the working vary utilizing computational fluid dynamics (CFD) to extend effectivity and to remove any possibility of solids increase, which may negatively influence efficiency and lead to pricey pump failures. “With the newly developed cutter system, the Alligator pumps can successfully break down all solids within the waste water and transport them away, saving both power and maintenance costs due to their excessive efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water purposes that require excessive supply pressure, but on the identical time should take care of many different sorts of solids.”
HOMA will be presenting the model new Alligator chopper pump collection for the primary time at IFAT 2022 in Munich. This and different improvements, such as the maintenance slide with sliding motor mount, might be explained and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
