Problematic solids such as sanitary towels, plastic baggage, textiles and wood are being discovered increasingly more usually in wastewater. Pumping and sewage remedy plants are subsequently more and more reaching their limits; items get clogged up and break down.
In instances when low lifecycle costs are playing an ever extra essential role, HOMA Pumpenfabrik offers an power environment friendly and reliable answer for areas where a high delivery head is required, but on the similar time, a diverse range of solids is expected: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator series enables effective operation via a powerful cutter system. Thanks to using highly sturdy chilled chrome forged iron, the main components that are subject to the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA will be presenting the brand new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs have gotten more and more necessary in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for power saving and dependable pumps that attain high supply heads with great effectivity.” With its new Alligator chopper pump series, 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 effectivity
“Our goal was to achieve excessive supply pressures in the medium circulate price vary,” reports Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and extra energy saving motor than in other pumps in the identical working vary was adequate. To achieve this, HOMA developed a new cutter system that effectively shreds and removes giant portions of various solids such as tear-resistant hygiene wipes, plastic luggage and wood, which additionally get into the wastewater through surface water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which can also be geared up with its own cutter. This design permits the 2 central components to work collectively to catch solids, break them down and finally remove them from the suction space through built-in grooves within the put on plate.
To enable larger efficiency without compromising on cutting performance, the blades of the impeller additionally curve strongly backwards. As a outcome, within the 50 Hz version, a move price of up to 130 m³/h and a delivery head of up to 57 m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of eight to twenty kW, a flow rate of as a lot as 140 m³/h and a delivery head of as much as 82 m are potential. The suction cowl mounted on the pump housing can also be used to regulate the cutting gap between the impeller and the put on and tear plate with the help of six set screws. “The strength of our new Alligator collection, which is out there for moist well set up in addition to dry installation, is its nice effectivity and effective cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
Low lifecycle prices due to wear-resistant design
In order to attain not solely the absolute best effectivity values within the working vary required for these kinds of wastewater functions, but additionally to reduce back lifecycle costs total, HOMA attaches nice significance to low-maintenance operation along with efficiency. The impeller and wear plate, that are the elements topic to essentially the most stress, are made from extremely sturdy chilled chrome cast iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In เกจวัดแรงดันไฟฟ้า , the hydraulics have been optimally designed for the operating vary using computational fluid dynamics (CFD) to increase effectivity and to get rid of any chance of solids building up, which can negatively impression performance and lead to pricey 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 each vitality and maintenance prices because of their high effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly suitable for waste water applications that require excessive delivery stress, but at the identical time have to deal with many various kinds of solids.”
HOMA will be presenting the new Alligator chopper pump series for the primary time at IFAT 2022 in Munich. This and other innovations, similar to the maintenance slide with sliding motor mount, will be defined and demonstrated by the HOMA sales group in Hall B1 at Stand 429/528.
