Problematic solids similar to sanitary towels, plastic baggage, textiles and wooden are being discovered increasingly more often in wastewater. Pumping and sewage remedy crops are due to this fact increasingly reaching their limits; items get clogged up and break down.
In times when low lifecycle prices are playing an ever more necessary role, HOMA Pumpenfabrik offers an vitality efficient and dependable resolution for areas where a high delivery head is required, but on the same time, a various range of solids is predicted: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator collection enables effective operation through a powerful cutter system. Thanks to the use of extremely sturdy chilled chrome forged iron, the principle parts which might be subject to essentially the most stress perform reliably even with abrasive substances similar to sand. HOMA will be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs are becoming more and more necessary 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 vitality saving and reliable pumps that reach excessive supply heads with great effectivity.” With its new Alligator chopper pump sequence, which will also be obtainable 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 aim was to achieve high supply pressures within the medium circulate rate range,” stories Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and extra vitality saving motor than in other pumps in the identical working vary was adequate. To obtain this, HOMA developed a new cutter system that effectively shreds and removes massive quantities of numerous solids corresponding to tear-resistant hygiene wipes, plastic baggage and wood, which also get into the wastewater via floor water. The specially designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which can also be outfitted with its personal cutter. This design allows the 2 central parts to work collectively to catch solids, break them down and finally take away them from the suction space via integrated grooves in the wear plate.
To allow higher effectivity with out compromising on slicing efficiency, the blades of the impeller also curve strongly backwards. As a result, in the 50 Hz version, a move rate of as a lot as 130 m³/h and a supply head of as a lot as fifty seven m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of eight to twenty kW, a move rate of as much as a hundred and forty m³/h and a supply head of up to 82 m are attainable. The suction cowl mounted on the pump housing can additionally be used to adjust the slicing hole between the impeller and the damage plate with the aid of six set screws. “The energy of our new Alligator sequence, which is available for moist properly set up in addition to dry set up, is its nice efficiency and efficient cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to realize not only the absolute best effectivity values within the operating range required for these sorts of wastewater purposes, but in addition to reduce back lifecycle prices overall, HOMA attaches nice significance to low-maintenance operation in addition to efficiency. The impeller and wear plate, that are the components topic to the most stress, are made of extremely durable chilled chrome cast iron, which withstands even abrasive substances corresponding to sand within the pumped medium. In addition, the hydraulics were optimally designed for the working range utilizing computational fluid dynamics (CFD) to extend efficiency and to get rid of any risk of solids build up, which can negatively influence performance and lead to costly pump failures. “With the newly developed cutter system, the Alligator pumps can successfully break down all solids in the waste water and transport them away, saving each power and maintenance prices because of their excessive efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “ เกจวัดแรงดัน4นิ้วราคา makes them particularly suitable for waste water applications that require excessive supply pressure, but at the similar time should cope with many different kinds of solids.”
HOMA will be presenting the brand new Alligator chopper pump collection for the primary time at IFAT 2022 in Munich. This and other improvements, such as the maintenance slide with sliding motor mount, shall be explained and demonstrated by the HOMA sales group in Hall B1 at Stand 429/528.
