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

Problematic solids such as sanitary towels, plastic bags, textiles and wooden are being found increasingly typically in wastewater. Pumping and sewage treatment crops are due to this fact more and more reaching their limits; units get clogged up and break down.
In occasions when low lifecycle costs are taking half in an ever extra essential role, HOMA Pumpenfabrik provides an vitality efficient and reliable answer for areas the place a excessive delivery head is required, but at the same time, a diverse vary of solids is anticipated: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection enables effective operation by way of a robust cutter system. Thanks to the use of highly sturdy chilled chrome forged iron, the principle components that are subject to probably the most stress carry out reliably even with abrasive substances similar to sand. HOMA will be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs have gotten more and more important 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 dependable pumps that reach excessive delivery heads with great effectivity.” With its new Alligator chopper pump sequence, which may even be obtainable as an explosion-proof model, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with high effectivity
“Our objective was to achieve high delivery pressures in the medium flow rate vary,” stories Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and extra vitality saving motor than in different pumps in the same operating vary was sufficient. To achieve this, HOMA developed a new cutter system that successfully shreds and removes massive portions of various solids corresponding to tear-resistant hygiene wipes, plastic baggage and wooden, which also get into the wastewater through surface water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the put on and tear plate, which can also be geared up with its own cutter. This design permits the two central components to work together 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 allow larger efficiency without compromising on slicing efficiency, the blades of the impeller also curve strongly backwards. As a result, within the 50 Hz version, a flow price of up to a hundred thirty m³/h and a delivery head of up to fifty seven m can be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of 8 to twenty kW, a flow fee of up to one hundred forty m³/h and a supply head of as a lot as eighty two m are possible. The suction cowl mounted on the pump housing may additionally be used to regulate the cutting hole between the impeller and the damage plate with the assist of six set screws. “The power of our new Alligator collection, which is out there for wet well set up 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 achieve not solely the absolute best effectivity values in the working range required for these sorts of wastewater purposes, but also to reduce lifecycle prices general, HOMA attaches nice significance to low-maintenance operation in addition to effectivity. The impeller and wear plate, which are the components subject to probably the most stress, are made of extraordinarily durable chilled chrome cast iron, which withstands even abrasive substances such as sand in the pumped medium. In pressure gauge น้ำมัน , the hydraulics were optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to extend efficiency and to get rid of any possibility of solids increase, which may negatively influence efficiency and result in costly pump failures. “With เกจวัดแรงดันถังแก๊ส developed cutter system, the Alligator pumps can successfully break down all solids in the waste water and transport them away, saving both power and upkeep costs because of their high effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water functions that require excessive delivery pressure, but on the similar time have to take care of many various sorts of solids.”
HOMA will be presenting the model new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and different improvements, similar to the maintenance slide with sliding motor mount, might be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
