Problematic solids corresponding to sanitary towels, plastic bags, textiles and wooden are being found increasingly more typically in wastewater. Pumping and sewage remedy vegetation are therefore increasingly reaching their limits; items get clogged up and break down.
In times when low lifecycle costs are taking half in an ever more essential function, HOMA Pumpenfabrik provides an energy efficient and reliable answer for areas the place a excessive supply head is required, however on the similar time, a diverse vary of solids is expected: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator collection enables effective operation via a powerful cutter system. Thanks to the use of highly durable chilled chrome forged iron, the primary elements which are subject to essentially the most stress perform reliably even with abrasive substances such as sand. HOMA will be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs have gotten increasingly necessary in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for energy saving and dependable pumps that reach excessive delivery heads with great effectivity.” With its new Alligator chopper pump sequence, which will also be out there as an explosion-proof version, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with high efficiency
“Our aim was to realize high delivery pressures in the medium move price range,” reports Konstantin Pörsch. Without forfeiting pump rate, the improved effectivity meant that a smaller, cheaper and extra vitality saving motor than in other pumps in the same operating vary was adequate. To achieve this, HOMA developed a new cutter system that effectively shreds and removes massive portions of various solids similar to tear-resistant hygiene wipes, plastic bags and wooden, which additionally get into the wastewater by way of 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 additionally be outfitted with its own cutter. This design allows the two central parts to work collectively to catch solids, break them down and in the end take away them from the suction space by way of built-in grooves within the put on plate.
To allow เครื่องมือตรวจวัดความดันเลือดเรียกว่า with out compromising on cutting efficiency, the blades of the impeller additionally curve strongly backwards. As a end result, in the 50 Hz model, a flow price of as a lot as a hundred thirty m³/h and a delivery head of as much as 57 m could be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of 8 to twenty kW, a move rate of as much as a hundred and forty m³/h and a delivery head of up to eighty two m are potential. The suction cover mounted on the pump housing can additionally be used to adjust the chopping gap between the impeller and the damage plate with the aid of six set screws. “The strength of our new Alligator series, which is available for wet nicely set up as properly as dry set up, is its nice efficiency and efficient cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle costs thanks to wear-resistant design
In order to achieve not only the absolute best effectivity values within the operating vary required for these sorts of wastewater functions, but additionally to scale back lifecycle prices total, HOMA attaches nice importance to low-maintenance operation in addition to effectivity. The impeller and wear plate, which are the parts topic to the most stress, are made from extremely durable chilled chrome cast iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics were optimally designed for the working vary utilizing computational fluid dynamics (CFD) to increase efficiency and to remove any risk of solids building up, which may negatively influence efficiency and lead to pricey pump failures. “With the newly developed cutter system, the Alligator pumps can successfully break down all solids within the waste water and transport them away, saving both energy and maintenance prices thanks to their high efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water purposes that require excessive delivery pressure, however on the similar time need to deal with many different sorts of solids.”
HOMA shall be presenting the new Alligator chopper pump collection for the first time at IFAT 2022 in Munich. This and other improvements, similar to the upkeep slide with sliding motor mount, will be explained and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
