Problematic solids similar to sanitary towels, plastic bags, textiles and wood are being discovered increasingly more often in wastewater. Pumping and sewage treatment plants are therefore more and more reaching their limits; items get clogged up and break down.
In instances when low lifecycle costs are playing an ever more necessary position, HOMA Pumpenfabrik presents an vitality environment friendly and dependable resolution for areas where a excessive delivery head is required, however on the similar time, a diverse vary of solids is anticipated: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator sequence permits efficient operation through a powerful cutter system. Thanks to the use of highly durable chilled chrome forged iron, the main elements which are topic to probably the most stress perform reliably even with abrasive substances corresponding to sand. HOMA shall be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest possible lifecycle prices have gotten increasingly essential in water and wastewater applications,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for energy saving and reliable pumps that reach excessive supply heads with great efficiency.” With its new Alligator chopper pump collection, which may 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 excessive effectivity
“Our aim was to realize excessive delivery pressures in the medium move rate range,” reports Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and extra vitality saving motor than in other pumps in the same operating range was sufficient. To obtain this, HOMA developed a new cutter system that effectively shreds and removes giant portions of numerous solids such as tear-resistant hygiene wipes, plastic baggage and wood, which additionally get into the wastewater through 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 personal cutter. This design allows the 2 central components to work collectively to catch solids, break them down and finally remove them from the suction area by way of integrated grooves within the put on plate.
To enable larger effectivity with out compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a result, within the 50 Hz model, a move rate of as a lot as a hundred thirty m³/h and a delivery head of up to 57 m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of eight to 20 kW, a move price of up to 140 m³/h and a supply head of as a lot as eighty two m are possible. The suction cover mounted on the pump housing can also be used to regulate the chopping gap between the impeller and the wear plate with the help of six set screws. “The energy of our new Alligator collection, which is on the market for moist well set up as nicely as dry installation, is its great effectivity and effective cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to realize not solely the very best efficiency values in the working vary required for these kinds of wastewater applications, but additionally to minimize back lifecycle prices general, HOMA attaches great importance to low-maintenance operation along with effectivity. The impeller and put on plate, that are the parts subject to the most stress, are made from extraordinarily durable chilled chrome cast iron, which withstands even abrasive substances such as sand within the pumped medium. In addition, the hydraulics were optimally designed for the working vary utilizing computational fluid dynamics (CFD) to increase effectivity and to remove any possibility of solids building up, which might negatively impression performance and lead to expensive 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 each power and maintenance prices because of their high efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably appropriate for waste water purposes that require excessive supply stress, however on the similar time have to deal with many various sorts of solids.”
HOMA might be presenting เกจวัดแก๊ส for the first time at IFAT 2022 in Munich. This and other improvements, such as the upkeep slide with sliding motor mount, shall be explained and demonstrated by the HOMA gross sales staff in Hall B1 at Stand 429/528.
