New chopper pump achieves excessive efficiency without compromising on slicing efficiency

Problematic solids such as sanitary towels, plastic bags, textiles and wood are being discovered increasingly typically in wastewater. Pumping and sewage treatment vegetation are therefore increasingly reaching their limits; models get clogged up and break down.
In occasions when low lifecycle costs are taking half in an ever more essential role, HOMA Pumpenfabrik presents an energy environment friendly and reliable solution for areas the place a excessive supply head is required, but on the similar time, a various range of solids is expected: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator sequence permits effective operation by way of a strong cutter system. Thanks to the utilization of highly sturdy chilled chrome forged iron, the main parts which are topic to the most stress perform reliably even with abrasive substances similar to sand. HOMA shall be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs have gotten more and more essential in water and wastewater functions,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for vitality saving and dependable pumps that attain high supply heads with great efficiency.” With its new Alligator chopper pump sequence, which may even be out there as an explosion-proof version, HOMA has developed a very environment friendly response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our objective was to achieve excessive supply pressures in the medium circulate price vary,” reports Konstantin Pörsch. Without forfeiting pressure gauge ราคา , the improved effectivity meant that a smaller, cheaper and extra energy saving motor than in different pumps in the identical operating range was adequate. To achieve this, HOMA developed a new cutter system that successfully shreds and removes large quantities of diverse solids similar to tear-resistant hygiene wipes, plastic baggage and wooden, which also get into the wastewater through floor water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which can additionally be outfitted with its personal cutter. This design allows the 2 central components to work together to catch solids, break them down and in the end remove them from the suction area by way of built-in grooves within the put on plate.
To enable larger efficiency without compromising on chopping efficiency, the blades of the impeller additionally curve strongly backwards. As a outcome, within the 50 Hz model, a circulate rate of as a lot as 130 m³/h and a delivery head of as a lot as fifty seven m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of eight to twenty kW, a flow price of up to a hundred and forty m³/h and a delivery head of as a lot as 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 help of six set screws. “The power of our new Alligator collection, which is on the market for moist properly set up as well as dry installation, is its great effectivity and efficient cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
Low lifecycle costs thanks to wear-resistant design
In order to achieve not only the best possible effectivity values in the working vary required for these kinds of wastewater applications, but also to reduce back lifecycle costs total, HOMA attaches nice significance to low-maintenance operation in addition to effectivity. The impeller and wear plate, which are the parts topic to probably the most stress, are manufactured from extraordinarily sturdy chilled chrome cast iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics have been optimally designed for the working range using computational fluid dynamics (CFD) to extend efficiency and to eliminate any chance of solids increase, which can negatively influence efficiency and result in 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 maintenance prices due to their high effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly suitable for waste water purposes that require high supply strain, however at the similar time should cope with many different sorts 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 innovations, such as the maintenance slide with sliding motor mount, will be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
