Problematic solids corresponding to sanitary towels, plastic luggage, textiles and wooden are being found increasingly often in wastewater. Pumping and sewage remedy plants are subsequently more and more reaching their limits; units get clogged up and break down.
In times when low lifecycle prices are enjoying an ever extra important position, HOMA Pumpenfabrik offers an energy environment friendly and reliable solution for areas the place a high supply head is required, but on the same time, a various range of solids is expected: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator collection enables efficient operation via a powerful cutter system. Thanks to the usage of highly durable chilled chrome cast iron, the main parts that are subject to probably the most stress carry out reliably even with abrasive substances such as sand. HOMA will be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs have gotten increasingly important in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for energy saving and reliable pumps that reach high supply heads with great effectivity.” With its new Alligator chopper pump series, which may also be available as an explosion-proof version, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with high effectivity
“Our goal was to realize excessive supply pressures within the medium circulate fee vary,” 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 same working vary was adequate. To obtain nuova fima pressure gauge ราคา , HOMA developed a brand new cutter system that successfully shreds and removes massive portions of numerous solids corresponding to tear-resistant hygiene wipes, plastic baggage and wooden, which additionally get into the wastewater through floor water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear plate, which can be outfitted with its personal cutter. This design permits the two central elements to work together to catch solids, break them down and ultimately remove them from the suction space by way of built-in grooves within the wear plate.
To allow larger efficiency without compromising on cutting performance, the blades of the impeller also curve strongly backwards. As a result, within the 50 Hz model, a flow rate of as a lot as one hundred thirty m³/h and a supply head of up to 57 m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of 8 to 20 kW, a move price of up to a hundred and forty m³/h and a delivery head of up to eighty two m are potential. The suction cover mounted on the pump housing may additionally be used to adjust the slicing hole between the impeller and the put on and tear plate with the help of six set screws. “The strength of our new Alligator sequence, which is out there for wet well installation in addition to dry set up, is its nice efficiency and efficient cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle prices due to wear-resistant design
In order to realize not solely the greatest possible effectivity values in the working range required for these sorts of wastewater applications, but also to scale back lifecycle costs overall, HOMA attaches nice significance to low-maintenance operation in addition to efficiency. The impeller and put on plate, which are the components subject to probably the most stress, are manufactured from extremely durable chilled chrome cast iron, which withstands even abrasive substances similar to sand in the pumped medium. In addition, the hydraulics have been optimally designed for the operating range using computational fluid dynamics (CFD) to increase effectivity and to remove any chance of solids building up, which may negatively impression performance 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 vitality and maintenance prices thanks to their high efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “ จำหน่ายเกจวัดแรงดัน makes them significantly suitable for waste water applications that require high supply pressure, but at the same time need to cope with many different sorts of solids.”
HOMA will be presenting the new Alligator chopper pump sequence for the first time at IFAT 2022 in Munich. This and different innovations, similar to the maintenance slide with sliding motor mount, will be defined and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
