Problematic solids such as sanitary towels, plastic baggage, textiles and wooden are being found increasingly more often in wastewater. Pumping and sewage therapy crops are subsequently more and more reaching their limits; models get clogged up and break down.
In instances when low lifecycle costs are playing an ever extra important function, HOMA Pumpenfabrik provides an vitality efficient and dependable solution for areas the place a excessive supply head is required, but on the same time, a diverse vary of solids is anticipated: the Alligator chopper pump sequence. เกจ์วัดแรงดันแก๊ส developed OC impeller of the Alligator collection allows effective operation via a strong cutter system. Thanks to the use of extremely sturdy chilled chrome forged iron, the main parts which might be subject to the most stress perform reliably even with abrasive substances similar to sand. HOMA might be presenting the brand new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs are becoming increasingly essential 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 great effectivity.” With its new Alligator chopper pump collection, which may even be available as an explosion-proof version, HOMA has developed a very environment friendly response to this demand.
Cutter system shreds all solids with high effectivity
“Our goal was to attain high supply pressures in the medium circulate price range,” reports Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and extra energy saving motor than in different pumps in the identical working range was sufficient. To obtain this, HOMA developed a new cutter system that effectively shreds and removes giant portions of diverse solids similar to tear-resistant hygiene wipes, plastic luggage and wooden, which also get into the wastewater by way of floor water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the put on and tear plate, which can be outfitted with its own cutter. This design allows the 2 central parts to work collectively to catch solids, break them down and ultimately take away them from the suction space via integrated grooves in the put on plate.
To allow larger efficiency with out compromising on cutting efficiency, the blades of the impeller also curve strongly backwards. As a result, in the 50 Hz model, a move fee of up to a hundred thirty m³/h and a delivery head of as much as fifty seven m could be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of eight to 20 kW, a move fee of as a lot 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 slicing hole between the impeller and the damage plate with assistance from six set screws. “The strength of our new Alligator sequence, which is available for wet properly installation in addition to dry installation, is its great effectivity and effective cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle prices due to wear-resistant design
In order to attain not solely the very best effectivity values within the working vary required for these sorts of wastewater purposes, but additionally to scale back lifecycle prices overall, HOMA attaches nice significance to low-maintenance operation along with efficiency. The impeller and put on plate, which are the elements subject to the most stress, are made of extremely sturdy chilled chrome cast iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics were optimally designed for the working vary using computational fluid dynamics (CFD) to extend effectivity and to remove any risk of solids increase, which may negatively impression performance and lead to expensive pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids in the waste water and transport them away, saving each power and upkeep costs thanks to their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water applications that require high delivery pressure, but at the similar time need to take care of many various kinds of solids.”
HOMA might be presenting the brand new Alligator chopper pump collection for the primary time at IFAT 2022 in Munich. This and different improvements, similar to the maintenance slide with sliding motor mount, shall be defined and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
