Problematic solids such as sanitary towels, plastic bags, textiles and wooden are being discovered increasingly more often in wastewater. Pumping and sewage treatment plants are subsequently more and more reaching their limits; items get clogged up and break down.
In occasions when low lifecycle costs are playing an ever more important function, HOMA Pumpenfabrik offers an energy efficient and dependable resolution for areas where a high delivery head is required, but at the same time, a various range of solids is predicted: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection enables effective operation through a robust cutter system. Thanks to the use of highly sturdy chilled chrome cast iron, the primary elements which would possibly be subject to essentially the most stress carry out reliably even with abrasive substances similar 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 increasingly necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for power saving and reliable pumps that attain excessive supply heads with nice efficiency.” With its new Alligator chopper pump series, which may also be out there as an explosion-proof model, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our aim was to attain excessive supply pressures in the medium circulate fee vary,” reviews Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and extra power saving motor than in other pumps in the identical working range was enough. To achieve this, HOMA developed a model new cutter system that effectively shreds and removes giant quantities of diverse solids such as tear-resistant hygiene wipes, plastic bags and wood, which additionally get into the wastewater through surface water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which is also outfitted with its own cutter. This design allows the two central components to work collectively to catch solids, break them down and finally take away them from the suction area by way of integrated grooves in the wear plate.
To allow เกจวัดแรงดันราคา with out compromising on chopping performance, the blades of the impeller additionally curve strongly backwards. As a end result, within the 50 Hz version, a flow price of as much as a hundred thirty m³/h and a supply head of as much as fifty seven m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of 8 to twenty kW, a circulate rate of as much as a hundred and forty m³/h and a supply head of up to 82 m are potential. The suction cowl mounted on the pump housing can additionally be used to regulate the cutting hole between the impeller and the put on and tear 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 great effectivity and effective cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle costs thanks to wear-resistant design
In order to achieve not solely the absolute best effectivity values within the operating range required for these kinds of wastewater functions, but also to reduce back lifecycle costs total, HOMA attaches nice importance to low-maintenance operation along with efficiency. The impeller and put on plate, that are the elements topic to 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 had been optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to increase efficiency and to eliminate any risk of solids build up, which can negatively influence efficiency and result in 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 energy and maintenance costs thanks to their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water applications that require excessive supply pressure, but at the same time need to deal with many different kinds of solids.”
HOMA will be presenting the new Alligator chopper pump collection for the primary time at IFAT 2022 in Munich. This and different innovations, corresponding to the maintenance slide with sliding motor mount, shall be defined and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
