Problematic solids similar to sanitary towels, plastic baggage, textiles and wood are being found increasingly often in wastewater. Pumping and sewage treatment crops are therefore increasingly reaching their limits; units get clogged up and break down.
In occasions when low lifecycle prices are playing an ever extra necessary function, HOMA Pumpenfabrik offers an energy environment friendly and reliable solution for areas where a high supply head is required, but on the similar time, a diverse range of solids is predicted: the Alligator chopper pump sequence. ที่วัดแรงดัน developed OC impeller of the Alligator sequence enables effective operation by way of a strong cutter system. Thanks to using highly sturdy chilled chrome forged iron, the main parts which are topic to the most stress carry out reliably even with abrasive substances similar to sand. HOMA might be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs are becoming more and more necessary in water and wastewater functions,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for energy saving and reliable pumps that attain excessive supply heads with nice efficiency.” With its new Alligator chopper pump series, which will also be out there as an explosion-proof version, HOMA has developed a very environment friendly response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our goal was to realize high supply pressures in the medium move price vary,” reports Konstantin Pörsch. Without forfeiting pump fee, the improved efficiency meant that a smaller, cheaper and more vitality saving motor than in different pumps in the identical working range was adequate. To achieve this, HOMA developed a model new cutter system that effectively shreds and removes large quantities of various solids such as tear-resistant hygiene wipes, plastic luggage and wooden, which also get into the wastewater via surface water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which can also be geared up with its own cutter. This design allows the 2 central elements to work together to catch solids, break them down and finally take away them from the suction area via integrated grooves within the wear plate.
To enable greater effectivity with out compromising on chopping efficiency, the blades of the impeller also curve strongly backwards. As a outcome, in the 50 Hz model, a move price of as a lot as 130 m³/h and a delivery head of up to 57 m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of eight to 20 kW, a flow price of up to 140 m³/h and a supply head of as a lot as eighty two m are attainable. The suction cover mounted on the pump housing may additionally be used to regulate the cutting hole between the impeller and the wear and tear plate with assistance from six set screws. “The power of our new Alligator sequence, which is out there for moist well set up as properly as dry set up, is its great effectivity and efficient cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to attain not solely the greatest possible efficiency values in the operating vary required for these sorts of wastewater applications, but also to scale back lifecycle prices general, HOMA attaches great importance to low-maintenance operation in addition to efficiency. The impeller and put on plate, which are the components 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 have been optimally designed for the working range utilizing computational fluid dynamics (CFD) to increase efficiency and to remove any risk of solids building up, which can negatively impression performance and lead to expensive pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids within the waste water and transport them away, saving each energy and upkeep costs due to their high efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water purposes that require high supply stress, however at the same time need to deal with many alternative kinds of solids.”
HOMA shall be presenting the new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and different improvements, similar to the upkeep slide with sliding motor mount, shall be explained and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
