Problematic solids such as sanitary towels, plastic baggage, textiles and wood are being discovered more and more often in wastewater. Pumping and sewage remedy vegetation are subsequently increasingly reaching their limits; units get clogged up and break down.
In occasions when low lifecycle costs are playing an ever extra important role, HOMA Pumpenfabrik presents an energy efficient and dependable resolution for areas where a excessive delivery head is required, but on the same time, a various range of solids is anticipated: the Alligator chopper pump series. The newly developed OC impeller of the Alligator sequence allows effective operation through a strong cutter system. Thanks to the utilization of highly durable chilled chrome forged iron, the main parts that are topic to essentially the most stress carry out reliably even with abrasive substances similar to sand. HOMA might be presenting xp2i for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle prices have gotten increasingly important in water and wastewater functions,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for power saving and dependable pumps that attain excessive delivery heads with great effectivity.” With its new Alligator chopper pump sequence, which will also be out there as an explosion-proof version, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with high efficiency
“Our objective was to attain excessive supply pressures in the medium move fee range,” stories Konstantin Pörsch. Without forfeiting pump fee, the improved efficiency meant that a smaller, cheaper and more energy saving motor than in other pumps in the identical operating range was adequate. To obtain this, HOMA developed a model new cutter system that successfully shreds and removes giant portions of various solids such as tear-resistant hygiene wipes, plastic bags and wood, which additionally get into the wastewater by way of surface water. pressure gauge ลม designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which is also equipped with its personal cutter. This design allows the two central parts to work collectively to catch solids, break them down and ultimately remove them from the suction space by way of integrated grooves within the put on plate.
To enable higher effectivity without compromising on chopping performance, the blades of the impeller also curve strongly backwards. As a end result, within the 50 Hz version, a flow price of up to 130 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 model, with energy consumption of eight to 20 kW, a flow price of as a lot as a hundred and forty m³/h and a delivery head of as much as eighty two m are potential. The suction cowl mounted on the pump housing can be used to adjust the chopping hole between the impeller and the damage plate with the assist of six set screws. “The strength of our new Alligator sequence, which is out there for moist well installation in addition to dry set up, is its nice effectivity and efficient cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to realize not only the best possible effectivity values in the operating range required for these kinds of wastewater purposes, but in addition to scale back lifecycle prices overall, HOMA attaches nice significance to low-maintenance operation along with efficiency. The impeller and wear plate, which are the parts subject to essentially the most stress, are made of extraordinarily durable chilled chrome forged iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics were optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to increase effectivity and to eliminate any possibility of solids increase, which may negatively impact efficiency and lead to costly pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids in the waste water and transport them away, saving both vitality and upkeep prices thanks to their excessive efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water functions that require high delivery stress, however at the identical time need to cope with many various sorts of solids.”
HOMA shall be presenting the model new Alligator chopper pump collection for the first time at IFAT 2022 in Munich. This and other innovations, corresponding to the upkeep slide with sliding motor mount, might be defined and demonstrated by the HOMA gross sales group in Hall B1 at Stand 429/528.
