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

Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wooden are being found more and more often in wastewater. Pumping and sewage therapy vegetation 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 enjoying an ever extra necessary position, HOMA Pumpenfabrik offers an energy environment friendly and reliable solution for areas where a excessive delivery head is required, however at the same time, a various range of solids is anticipated: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator sequence enables effective operation via a powerful cutter system. Thanks to the usage of highly durable chilled chrome forged iron, the primary elements that are subject to the most stress carry out reliably even with abrasive substances such as sand. HOMA shall be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle prices have gotten more and more important in water and wastewater functions,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for energy saving and dependable pumps that reach high supply heads with nice effectivity.” With its new Alligator chopper pump collection, which may even be available as an explosion-proof version, HOMA has developed a very environment friendly response to this demand.
Cutter system shreds all solids with high efficiency
“Our goal was to achieve excessive supply pressures within the medium flow fee vary,” stories Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and more vitality saving motor than in different pumps in the same operating range was sufficient. To achieve this, HOMA developed a new cutter system that successfully shreds and removes giant portions of numerous solids similar to tear-resistant hygiene wipes, plastic baggage and wood, which additionally get into the wastewater by way of surface water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear and tear plate, which is also outfitted with its personal cutter. This design permits the 2 central parts to work together to catch solids, break them down and finally remove them from the suction space through built-in grooves within the wear plate.
To allow larger efficiency with out compromising on cutting efficiency, the blades of the impeller also curve strongly backwards. As a result, within the 50 Hz model, a flow rate of as much as one hundred thirty 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 20 kW, a move fee of as much as one hundred forty m³/h and a delivery head of up to 82 m are possible. The suction cowl mounted on the pump housing can be used to regulate the cutting gap between the impeller and the wear plate with assistance from six set screws. “The energy of our new Alligator sequence, which is available for moist well installation as well as dry set up, is its nice effectivity and efficient cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle costs thanks to wear-resistant design
In order to achieve not solely the absolute best efficiency values in the working vary required for these kinds of wastewater functions, but additionally to cut back lifecycle costs total, HOMA attaches great importance to low-maintenance operation along with effectivity. pressure gauge แบบ น้ำมัน and put on plate, that are the components 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 working vary utilizing computational fluid dynamics (CFD) to extend efficiency and to remove any risk of solids build up, which can negatively influence performance and lead to pricey 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 vitality and upkeep costs due to their high efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly suitable for waste water functions that require high delivery pressure, but on the similar time need to deal with many various sorts 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 improvements, such as the maintenance slide with sliding motor mount, might be explained and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
