Problematic solids such as sanitary towels, plastic baggage, textiles and wood are being found more and more typically in wastewater. Pumping and sewage therapy crops are due to this fact more and more reaching their limits; models get clogged up and break down.
In instances when low lifecycle costs are enjoying an ever more necessary position, HOMA Pumpenfabrik offers an vitality efficient and dependable solution for areas where a excessive delivery head is required, however at the similar time, a diverse range of solids is predicted: the Alligator chopper pump series. The newly developed OC impeller of the Alligator series allows effective operation through a strong cutter system. Thanks to the usage of extremely durable chilled chrome cast iron, the main components that are topic to essentially the most stress perform reliably even with abrasive substances such as sand. HOMA shall be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest attainable 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 energy saving and reliable pumps that attain high supply heads with nice efficiency.” With its new Alligator chopper pump collection, which will also be obtainable as an explosion-proof version, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our goal was to realize excessive delivery pressures in the medium move price vary,” reviews Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and more vitality saving motor than in other pumps in the identical operating range was sufficient. To obtain this, HOMA developed a new cutter system that effectively shreds and removes giant quantities of numerous solids corresponding to tear-resistant hygiene wipes, plastic bags and wood, which additionally get into the wastewater by way of surface water. เกจวัดแรงดันแก๊สอาร์กอน designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear plate, which can additionally be equipped with its personal cutter. This design allows the 2 central components to work collectively to catch solids, break them down and ultimately remove them from the suction area via integrated grooves within the wear plate.
To enable larger efficiency with out compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a result, in the 50 Hz model, a circulate rate of as a lot as a hundred thirty m³/h and a delivery head of as much as fifty seven m could be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of eight to twenty kW, a flow fee of up to one hundred forty m³/h and a supply head of as a lot as 82 m are potential. The suction cover mounted on the pump housing may additionally be used to regulate the chopping gap between the impeller and the damage plate with assistance from six set screws. “The energy of our new Alligator series, which is on the market for wet properly installation in addition to dry installation, is its great efficiency and efficient cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to realize not solely the very best efficiency values within the working range required for these kinds of wastewater functions, but additionally to scale back lifecycle prices overall, HOMA attaches nice importance to low-maintenance operation in addition to efficiency. The impeller and put on plate, that are the parts subject to probably the most stress, are made of extraordinarily durable chilled chrome cast iron, which withstands even abrasive substances corresponding to sand within 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 get rid of any possibility of solids increase, which might negatively influence performance and lead to expensive 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 power and upkeep costs due to their excessive efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water purposes that require high supply strain, but at the similar time need to deal with many various kinds of solids.”
HOMA might be presenting the model new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and different improvements, corresponding to the maintenance slide with sliding motor mount, might be defined and demonstrated by the HOMA gross sales group in Hall B1 at Stand 429/528.
