New chopper pump achieves excessive effectivity without compromising on chopping efficiency

Problematic solids similar to sanitary towels, plastic luggage, textiles and wooden are being found increasingly usually in wastewater. Pumping and sewage remedy plants are therefore increasingly reaching their limits; items get clogged up and break down.
In occasions when low lifecycle prices are enjoying an ever extra necessary function, HOMA Pumpenfabrik presents an energy efficient and dependable resolution for areas where a high delivery head is required, but on the same time, a various range of solids is anticipated: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator sequence permits effective operation via a powerful cutter system. Thanks to the utilization of extremely sturdy chilled chrome cast iron, the principle parts which are topic to probably the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA shall be presenting the model new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
เกจ์วัดแรงดันน้ำมันเครื่อง have gotten increasingly necessary in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for energy saving and dependable pumps that reach excessive supply heads with nice efficiency.” With its new Alligator chopper pump series, which may even be obtainable as an explosion-proof model, HOMA has developed a very environment friendly response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our goal was to achieve excessive delivery pressures within the medium flow rate vary,” reports Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and more energy saving motor than in different pumps in the same operating vary was sufficient. To achieve this, HOMA developed a new cutter system that successfully shreds and removes giant quantities of numerous solids such as tear-resistant hygiene wipes, plastic luggage and wooden, which additionally get into the wastewater via surface water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the put on and tear plate, which is also equipped with its personal cutter. This design allows the 2 central parts to work together to catch solids, break them down and in the end remove them from the suction area by way of integrated grooves in the put on plate.
To enable greater effectivity with out compromising on slicing performance, the blades of the impeller also curve strongly backwards. As a end result, within the 50 Hz version, a flow rate of as much as one hundred thirty m³/h and a supply head of as much as 57 m can be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of eight to 20 kW, a move fee of up to one hundred forty m³/h and a delivery head of as much as 82 m are possible. The suction cover mounted on the pump housing can be used to regulate the cutting gap between the impeller and the wear plate with the assist of six set screws. “The power of our new Alligator collection, which is out there for moist nicely installation in addition to dry set up, is its nice 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 attain not only the absolute best efficiency values in the operating vary required for these kinds of wastewater purposes, but also to reduce lifecycle prices overall, HOMA attaches great importance to low-maintenance operation along with efficiency. The impeller and put on plate, that are the elements subject to the most stress, are manufactured from extremely sturdy chilled chrome forged iron, which withstands even abrasive substances similar to sand within the pumped medium. In addition, the hydraulics were optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to increase effectivity and to remove any risk of solids increase, which may negatively influence efficiency and result in expensive pump failures. “With the newly developed cutter system, the Alligator pumps can successfully break down all solids within the waste water and transport them away, saving both energy and upkeep prices thanks to their high efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water purposes that require high delivery strain, but on the similar time have to take care of many alternative 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, might be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
