New chopper pump achieves excessive effectivity with out compromising on chopping performance

Problematic solids such as sanitary towels, plastic luggage, textiles and wooden are being discovered increasingly often in wastewater. Pumping and sewage therapy plants are due to this fact more and more reaching their limits; units get clogged up and break down.
In instances when low lifecycle prices are playing an ever more important role, HOMA Pumpenfabrik provides an energy environment friendly and dependable answer for areas where a high supply head is required, but at the same time, a various range of solids is anticipated: the Alligator chopper pump collection. เครื่องมือตรวจวัดความดันเลือดเรียกว่า developed OC impeller of the Alligator series permits efficient operation by way of a powerful cutter system. Thanks to using extremely durable chilled chrome forged iron, the primary elements that are topic to the most stress carry out reliably even with abrasive substances such as sand. HOMA will be presenting the model new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs have gotten more and more necessary in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for energy saving and reliable pumps that reach excessive delivery heads with nice effectivity.” With its new Alligator chopper pump sequence, which may also be obtainable as an explosion-proof model, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our aim was to achieve excessive delivery pressures within the medium move fee vary,” reports Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and extra power saving motor than in other pumps in the same working range was sufficient. To obtain this, HOMA developed a new cutter system that effectively shreds and removes giant portions of various solids similar to tear-resistant hygiene wipes, plastic baggage and wooden, which additionally get into the wastewater through floor water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear and tear plate, which can additionally be geared up with its own cutter. This design permits the 2 central elements to work together to catch solids, break them down and in the end take away them from the suction area via built-in grooves in the wear plate.
To allow higher efficiency with out compromising on chopping performance, the blades of the impeller additionally curve strongly backwards. As a outcome, in the 50 Hz model, a flow fee of as much as 130 m³/h and a supply head of as much as 57 m could be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of 8 to 20 kW, a move rate of as much as one hundred forty m³/h and a supply head of as much as eighty two m are attainable. The suction cover mounted on the pump housing can be used to adjust the slicing gap between the impeller and the put on and tear plate with the assist of six set screws. “The power of our new Alligator collection, which is on the market for moist nicely set up as nicely as dry set up, is its nice effectivity and efficient cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle prices due to wear-resistant design
In order to achieve not solely the very best effectivity values within the operating range required for these kinds of wastewater functions, but also to scale back lifecycle costs total, HOMA attaches great significance to low-maintenance operation in addition to efficiency. The impeller and put on plate, which are the parts topic to probably the most stress, are made from extremely sturdy chilled chrome forged iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics had been optimally designed for the working vary utilizing computational fluid dynamics (CFD) to increase effectivity and to remove any possibility of solids building up, which may negatively impact efficiency and result in costly pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids within the waste water and transport them away, saving both vitality and maintenance costs because of their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “ pressure gauge ไฮ ด รอ ลิ ค makes them significantly appropriate for waste water purposes that require excessive supply stress, but at the similar time have to take care of many different kinds of solids.”
HOMA will be presenting the model new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and other innovations, similar to the maintenance slide with sliding motor mount, will be explained and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
