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

Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wooden are being discovered increasingly more often in wastewater. Pumping and sewage remedy vegetation are therefore more and more reaching their limits; items get clogged up and break down.
In times when low lifecycle prices are enjoying an ever extra essential role, HOMA Pumpenfabrik provides an energy environment friendly and dependable resolution for areas where a excessive 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 through a robust cutter system. Thanks to the use of extremely durable chilled chrome forged iron, the primary parts which may be topic to probably the most stress carry out reliably even with abrasive substances such as sand. HOMA might be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs have gotten more and more important 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 power saving and reliable pumps that attain high delivery heads with nice effectivity.” With its new Alligator chopper pump collection, which may even be obtainable as an explosion-proof model, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our goal was to achieve excessive supply pressures in the medium move fee vary,” reports Konstantin Pörsch. Without forfeiting เกจวัดแรงดันน้ำมันเครื่อง , the improved efficiency meant that a smaller, cheaper and extra energy saving motor than in different pumps in the identical working vary was enough. To achieve this, HOMA developed a model new cutter system that successfully shreds and removes giant portions of numerous solids corresponding to tear-resistant hygiene wipes, plastic bags and wooden, which additionally get into the wastewater via floor water. เกจวัดแรงดันดิจิตอล designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the wear plate, which can be equipped with its personal cutter. This design permits the two central parts to work collectively to catch solids, break them down and finally remove them from the suction space by way of integrated grooves in the wear plate.
To enable larger effectivity with out compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a outcome, in the 50 Hz model, a circulate rate of as a lot as 130 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 version, with power consumption of eight to 20 kW, a circulate price of as much as a hundred and forty m³/h and a delivery 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 slicing hole between the impeller and the damage plate with the assist of six set screws. “The strength of our new Alligator series, which is on the market for moist well set up as well as dry set up, is its great efficiency and effective cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle costs thanks to wear-resistant design
In order to achieve not solely the absolute best efficiency values in the operating vary required for these kinds of wastewater applications, but in addition to scale back lifecycle costs overall, HOMA attaches great importance to low-maintenance operation along with efficiency. The impeller and wear plate, which are the components subject to essentially the most stress, are made 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 working range utilizing computational fluid dynamics (CFD) to extend efficiency and to remove any chance of solids building up, which may negatively impression performance and result in costly 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 energy and maintenance prices thanks to their excessive effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water purposes that require excessive delivery pressure, however at the identical time need to deal with many different kinds of solids.”
HOMA will be presenting the new Alligator chopper pump collection for the first time at IFAT 2022 in Munich. This and other innovations, such as the maintenance slide with sliding motor mount, shall be explained and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
