New chopper pump achieves excessive efficiency with out compromising on slicing performance

เครื่องมือวัดความดันคือ corresponding to sanitary towels, plastic luggage, textiles and wood are being discovered increasingly more usually in wastewater. Pumping and sewage remedy crops are subsequently more and more reaching their limits; items get clogged up and break down.
In instances when low lifecycle prices are taking half in an ever extra important position, HOMA Pumpenfabrik presents an energy environment friendly and reliable resolution for areas where a excessive delivery head is required, but at the same time, a various range of solids is predicted: the Alligator chopper pump series. The newly developed OC impeller of the Alligator series enables efficient operation via a robust cutter system. Thanks to the usage of highly durable chilled chrome forged iron, the primary parts that are topic to the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA might be presenting the brand new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle prices have gotten more and more important in water and wastewater applications,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for vitality saving and dependable pumps that reach excessive delivery heads with nice efficiency.” With its new Alligator chopper pump series, 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 objective was to attain excessive delivery pressures within the medium circulate price range,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and more vitality saving motor than in other pumps in the identical working vary was adequate. To obtain this, HOMA developed a new cutter system that successfully shreds and removes large quantities 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 wear plate, which can also be equipped with its own cutter. This design permits the 2 central components to work together to catch solids, break them down and finally remove them from the suction space via built-in grooves within the put on plate.
To enable larger efficiency without 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 up to a hundred thirty m³/h and a supply head of up to fifty seven m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of 8 to twenty kW, a flow fee of up to a hundred and forty m³/h and a delivery head of as a lot as 82 m are possible. The suction cover mounted on the pump housing can be used to adjust the cutting gap between the impeller and the wear plate with the help of six set screws. “The strength of our new Alligator sequence, which is available for moist nicely installation in addition to dry installation, is its nice effectivity and effective cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle prices due to wear-resistant design
In order to attain not solely the best possible efficiency values within the operating vary required for these sorts of wastewater applications, but additionally to scale back lifecycle prices overall, HOMA attaches nice importance to low-maintenance operation in addition to efficiency. The impeller and put on plate, which are the components topic to essentially the most stress, are made of extremely sturdy chilled chrome forged iron, which withstands even abrasive substances corresponding to sand within the pumped medium. In addition, the hydraulics had been optimally designed for the working range utilizing computational fluid dynamics (CFD) to increase effectivity and to get rid of any chance of solids build up, which might negatively impression performance 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 each power and upkeep costs because of their excessive effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly suitable for waste water purposes that require excessive supply stress, but at the similar time should deal with many alternative sorts of solids.”
HOMA will be presenting เกจวัดแรงดัน250bar for the first time at IFAT 2022 in Munich. This and other improvements, such as the upkeep slide with sliding motor mount, will be defined and demonstrated by the HOMA gross sales group in Hall B1 at Stand 429/528.
