Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wood are being found more and more typically in wastewater. Pumping and sewage remedy vegetation are subsequently increasingly reaching their limits; models get clogged up and break down.
In occasions when low lifecycle prices are playing an ever extra necessary function, HOMA Pumpenfabrik provides an energy environment friendly and dependable solution for areas where a high delivery head is required, but on the identical time, a diverse vary of solids is expected: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator sequence permits efficient operation via a powerful cutter system. Thanks to the use of extremely sturdy chilled chrome cast iron, the main elements which are subject to probably 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 possible lifecycle costs are becoming more and more essential in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and dependable pumps that reach excessive delivery heads with great efficiency.” With เกจแรงดัน , which will also be obtainable as an explosion-proof model, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our aim was to attain excessive supply pressures in the medium move price vary,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and more power saving motor than in other pumps in the identical working vary was adequate. To achieve this, HOMA developed a brand new cutter system that successfully shreds and removes large quantities of diverse solids similar to tear-resistant hygiene wipes, plastic bags and wood, which additionally get into the wastewater via floor water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which is also equipped with its personal cutter. This design permits the 2 central parts to work together to catch solids, break them down and ultimately remove them from the suction space via integrated grooves in the put on plate.
To enable greater effectivity with out compromising on chopping performance, the blades of the impeller additionally curve strongly backwards. As a result, within the 50 Hz version, a flow fee of up to a hundred thirty m³/h and a supply head of up to 57 m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of 8 to 20 kW, a circulate price of up to one hundred forty m³/h and a delivery head of as a lot as eighty two m are attainable. The suction cover mounted on the pump housing can also be used to regulate the slicing gap between the impeller and the damage plate with the assist of six set screws. “The power of our new Alligator sequence, which is out there for moist nicely installation in addition to dry installation, is its great efficiency and efficient cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design
In order to realize not only the absolute best effectivity values in the operating vary required for these sorts of wastewater purposes, but additionally to reduce lifecycle costs total, HOMA attaches nice importance to low-maintenance operation along with effectivity. The impeller and put on plate, that are the elements subject to essentially the most stress, are made from extraordinarily 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 utilizing computational fluid dynamics (CFD) to extend effectivity and to get rid of any chance of solids increase, which may negatively impact efficiency and result in 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 both energy and upkeep prices due to their high effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water purposes that require excessive delivery stress, but at the similar time should cope with many various sorts of solids.”
HOMA will be presenting the new Alligator chopper pump sequence for the first time at IFAT 2022 in Munich. This and other innovations, such as the maintenance slide with sliding motor mount, will be explained and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
