Problematic solids corresponding to sanitary towels, plastic bags, textiles and wood are being found increasingly often in wastewater. Pumping and sewage therapy crops are therefore increasingly reaching their limits; units get clogged up and break down.
In instances when low lifecycle costs are enjoying an ever more important role, HOMA Pumpenfabrik offers an power environment friendly and dependable solution for areas the place a high supply head is required, however on the identical time, a various vary of solids is expected: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator sequence enables efficient operation through a robust cutter system. Thanks to the use of extremely sturdy chilled chrome forged iron, the principle components that are topic to the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA might be presenting the 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 division at HOMA Pumpenfabrik GmbH. “There is a growing demand for energy saving and reliable pumps that attain excessive supply heads with nice effectivity.” With its new Alligator chopper pump collection, which may even 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 efficiency
“Our goal was to attain excessive delivery pressures in the medium move rate vary,” stories Konstantin Pörsch. Without forfeiting pump rate, the improved effectivity meant that a smaller, cheaper and more vitality saving motor than in different pumps in the identical operating range was adequate. To obtain this, HOMA developed a brand new cutter system that effectively shreds and removes massive portions of numerous solids similar to tear-resistant hygiene wipes, plastic baggage and wooden, which also get into the wastewater through floor water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the put on and tear plate, which can also be geared up with its personal cutter. This design allows the 2 central components to work together to catch solids, break them down and finally remove them from the suction space by way of built-in grooves within the put on plate.
To enable higher effectivity with out compromising on cutting efficiency, the blades of the impeller also curve strongly backwards. As a outcome, within the 50 Hz model, a move fee of as much as a hundred thirty m³/h and a supply head of as much as fifty seven m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of eight to 20 kW, a flow fee of up to a hundred and forty m³/h and a supply head of up to 82 m are attainable. The suction cover mounted on the pump housing may also be used to regulate the cutting hole between the impeller and the damage plate with assistance from six set screws. “The energy of our new Alligator collection, which is on the market for wet nicely installation as well as dry set up, is its great efficiency and effective cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle costs because of wear-resistant design
In order to realize not only the very best effectivity values in the operating vary required for these sorts of wastewater applications, but also to reduce lifecycle prices general, HOMA attaches great importance to low-maintenance operation along with effectivity. The impeller and wear plate, that are the elements subject to essentially the most stress, are manufactured from extremely sturdy chilled chrome forged iron, which withstands even abrasive substances such as sand within the pumped medium. In เกจวัดแรงดันลมคือ , the hydraulics were optimally designed for the working range using computational fluid dynamics (CFD) to increase effectivity and to eliminate any chance of solids building up, which may negatively impression performance and result in 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 each energy and maintenance costs due to their high effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water applications that require high delivery pressure, however at the similar time need to cope with many alternative kinds of solids.”
HOMA will be presenting the model new Alligator chopper pump sequence for the first time at IFAT 2022 in Munich. This and different improvements, corresponding to the upkeep slide with sliding motor mount, might be defined and demonstrated by the HOMA sales group in Hall B1 at Stand 429/528.
