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

Problematic solids such as sanitary towels, plastic luggage, textiles and wooden are being found increasingly usually in wastewater. Pumping and sewage treatment crops are subsequently increasingly reaching their limits; units get clogged up and break down.
In occasions when low lifecycle costs are enjoying an ever extra necessary role, HOMA Pumpenfabrik presents an energy efficient and reliable solution for areas where a excessive delivery head is required, but on the similar time, a various vary of solids is expected: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator series enables effective operation by way of a powerful cutter system. Thanks to the use of extremely durable chilled chrome forged iron, the primary components which are topic to the most stress perform reliably even with abrasive substances corresponding to sand. HOMA might be presenting pressure gauge 2.5 นิ้ว for the first time at IFAT 2022 in Munich.
“The lowest potential lifecycle prices are becoming more and more necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for energy saving and dependable pumps that attain high delivery heads with nice efficiency.” With its new Alligator chopper pump collection, which will also be out there as an explosion-proof version, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with high effectivity

“Our aim was to achieve excessive delivery pressures in the medium circulate fee vary,” reviews Konstantin Pörsch. Without forfeiting pump fee, the improved efficiency meant that a smaller, cheaper and extra power saving motor than in different pumps in the identical working vary was enough. To achieve this, HOMA developed a new cutter system that successfully shreds and removes massive quantities of diverse solids such as tear-resistant hygiene wipes, plastic bags and wood, which also get into the wastewater by way of surface water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which can be equipped with its personal cutter. This design allows the 2 central components to work collectively to catch solids, break them down and in the end remove them from the suction area by way of built-in grooves in the put on plate.
To allow larger efficiency without compromising on slicing performance, the blades of the impeller also curve strongly backwards. As a outcome, in the 50 Hz version, a flow fee of up to a hundred thirty m³/h and a delivery head of as much as fifty seven m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of eight to twenty kW, a move fee of up to 140 m³/h and a delivery head of up to 82 m are potential. The suction cowl mounted on the pump housing can be used to adjust the chopping hole between the impeller and the damage plate with the assist of six set screws. “The power of our new Alligator sequence, which is out there for wet properly set up as well as dry set up, is its great efficiency and effective 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 very best efficiency values in the operating range required for these sorts of wastewater functions, but in addition to scale back lifecycle prices general, HOMA attaches nice significance to low-maintenance operation in addition to effectivity. The impeller and wear plate, which are the components topic to essentially the most stress, are made from extraordinarily sturdy chilled chrome forged iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics have been optimally designed for the operating range using computational fluid dynamics (CFD) to increase efficiency and to eliminate any risk of solids build up, which can negatively impression performance and lead to costly pump failures. “With the newly developed cutter system, the Alligator pumps can successfully break down all solids in the waste water and transport them away, saving both power and maintenance prices because of their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably appropriate for waste water functions that require high supply stress, however at the similar time need to cope with many various sorts of solids.”

HOMA shall be presenting the brand new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and other innovations, corresponding to the upkeep slide with sliding motor mount, shall be explained and demonstrated by the HOMA gross sales staff in Hall B1 at Stand 429/528.
