Problematic solids similar to sanitary towels, plastic bags, textiles and wooden are being discovered increasingly more often in wastewater. Pumping and sewage remedy crops are due to this fact more and more reaching their limits; models get clogged up and break down.
In times when low lifecycle prices are enjoying an ever more important position, HOMA Pumpenfabrik provides an power environment friendly and dependable answer for areas the place a excessive delivery head is required, but on the similar time, a various vary of solids is predicted: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator series permits efficient operation by way of a robust cutter system. เกจวัดแรงดันราคา to the utilization of highly durable chilled chrome forged iron, the principle components which would possibly be topic to the most stress perform reliably even with abrasive substances such as sand. HOMA shall be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs have gotten increasingly necessary in water and wastewater functions,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for vitality saving and reliable pumps that reach high supply heads with great effectivity.” With its new Alligator chopper pump sequence, which may also be available as an explosion-proof version, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with high effectivity
“Our goal was to realize excessive delivery pressures within the medium move rate range,” stories Konstantin Pörsch. Without forfeiting pump rate, the improved effectivity meant that a smaller, cheaper and extra energy saving motor than in different pumps in the identical working vary was adequate. To obtain this, HOMA developed a new cutter system that effectively shreds and removes massive quantities of numerous solids similar to tear-resistant hygiene wipes, plastic baggage and wooden, which also get into the wastewater by way of floor water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear plate, which is also equipped with its own cutter. This design permits the 2 central components to work collectively to catch solids, break them down and finally remove them from the suction area via integrated grooves within the wear plate.
To enable larger efficiency without compromising on cutting efficiency, the blades of the impeller additionally curve strongly backwards. As a result, within the 50 Hz model, a move rate of up to 130 m³/h and a delivery head of up to fifty seven m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of 8 to twenty kW, a move price of up to one hundred forty m³/h and a supply head of up to eighty two m are possible. The suction cover mounted on the pump housing can additionally be used to regulate the slicing hole between the impeller and the wear and tear plate with the assist of six set screws. “The power of our new Alligator collection, which is available for moist nicely installation in addition to dry installation, is its nice effectivity and effective cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to attain not solely the absolute best efficiency values in the working range required for these kinds of wastewater purposes, but also to reduce lifecycle costs overall, HOMA attaches great significance to low-maintenance operation in addition to efficiency. The impeller and wear plate, that are the elements subject to probably the most stress, are manufactured from extraordinarily durable chilled chrome forged iron, which withstands even abrasive substances such as sand within the pumped medium. In addition, the hydraulics have been optimally designed for the operating range utilizing computational fluid dynamics (CFD) to increase efficiency and to eliminate any risk of solids increase, which may negatively impression efficiency and result in costly pump failures. “With the newly developed cutter system, the Alligator pumps can successfully break down all solids in the waste water and transport them away, saving each vitality and maintenance prices thanks to their excessive efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly suitable for waste water purposes that require high supply pressure, but at the similar time need to deal with many various kinds of solids.”
HOMA might be presenting the brand new Alligator chopper pump series for the primary time at IFAT 2022 in Munich. This and other improvements, similar to the maintenance slide with sliding motor mount, will be explained and demonstrated by the HOMA gross sales staff in Hall B1 at Stand 429/528.
