New chopper pump achieves high effectivity with out compromising on slicing efficiency

Problematic solids corresponding to sanitary towels, plastic bags, textiles and wood are being found more and more typically in wastewater. Pumping and sewage remedy crops are due to this fact more and more reaching their limits; models get clogged up and break down.
In instances when low lifecycle costs are enjoying an ever more important position, HOMA Pumpenfabrik provides an power efficient and reliable solution for areas the place a excessive supply head is required, however on the identical time, a diverse vary of solids is anticipated: the Alligator chopper pump series. The newly developed OC impeller of the Alligator sequence permits efficient operation through a robust cutter system. Thanks to the use of extremely durable chilled chrome cast iron, the primary components which are topic to probably the most stress perform reliably even with abrasive substances corresponding to sand. HOMA might be presenting the brand new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest potential lifecycle prices have gotten increasingly necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and reliable pumps that attain high supply heads with great efficiency.” With its new Alligator chopper pump series, which will also be out there as an explosion-proof model, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our goal was to attain excessive supply pressures in the medium circulate fee vary,” reports Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and more energy saving motor than in different pumps in the identical operating vary was adequate. To achieve this, HOMA developed a brand new cutter system that effectively shreds and removes large portions of numerous solids such as tear-resistant hygiene wipes, plastic baggage and wooden, which also get into the wastewater via floor water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which can additionally be equipped with its own cutter. This design permits the two central parts to work together to catch solids, break them down and finally take away them from the suction area via built-in grooves in the wear plate.
To allow higher efficiency with out compromising on slicing efficiency, the blades of the impeller additionally curve strongly backwards. As a outcome, within the 50 Hz model, a move fee of up to one hundred thirty m³/h and a supply head of up to fifty seven m can be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of eight to twenty kW, a flow price of up to one hundred forty m³/h and a supply head of up to 82 m are attainable. The suction cover mounted on the pump housing can be used to regulate the slicing gap between the impeller and the damage plate with the assist of six set screws. “ pressure gauge 4 นิ้ว ราคา of our new Alligator collection, which is available for moist nicely installation as well as dry installation, is its great effectivity and efficient cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle prices due 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 in addition to scale back lifecycle costs total, HOMA attaches great significance to low-maintenance operation along with effectivity. The impeller and put on plate, which are the elements subject to essentially the most stress, are made from extraordinarily sturdy chilled chrome cast iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics had been optimally designed for the operating range using computational fluid dynamics (CFD) to increase effectivity and to remove any chance of solids building up, which may negatively impression performance and lead to expensive pump failures. “With เกจวัดแรงดันแก๊สหุงต้ม developed cutter system, the Alligator pumps can successfully break down all solids within the waste water and transport them away, saving each vitality and maintenance prices because of their excessive effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water applications that require high delivery strain, however at the same time have to cope with many alternative sorts of solids.”
HOMA shall be presenting the new Alligator chopper pump series for the primary time at IFAT 2022 in Munich. This and different innovations, similar to the maintenance slide with sliding motor mount, shall be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
