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

Problematic solids such as sanitary towels, plastic luggage, textiles and wood are being found more and more usually in wastewater. Pumping and sewage therapy vegetation are therefore increasingly reaching their limits; models get clogged up and break down.
In occasions when low lifecycle prices are playing an ever extra necessary role, HOMA Pumpenfabrik presents an energy efficient and dependable solution for areas where a excessive delivery head is required, however at the same time, a diverse range of solids is expected: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator series enables efficient operation by way of a strong cutter system. Thanks to the use of highly sturdy chilled chrome forged iron, the principle parts which are topic to the most stress perform reliably even with abrasive substances similar to sand. HOMA might be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs have gotten increasingly essential 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 reach excessive supply heads with nice effectivity.” With its new Alligator chopper pump sequence, which will also be obtainable as an explosion-proof version, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our objective was to realize excessive delivery pressures in the medium circulate price vary,” reports Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and more power saving motor than in different pumps in the identical operating range was sufficient. To obtain this, HOMA developed a model new cutter system that successfully shreds and removes giant portions of numerous solids similar to tear-resistant hygiene wipes, plastic bags and wooden, which also get into the wastewater through surface 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 equipped with its personal cutter. This design permits the two central parts to work collectively to catch solids, break them down and in the end take away them from the suction space by way of built-in grooves within the put on plate.
To allow greater effectivity without compromising on cutting efficiency, the blades of the impeller also curve strongly backwards. As a outcome, in the 50 Hz model, a flow fee of as much as one hundred thirty m³/h and a supply head of up to 57 m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of eight to twenty kW, a flow rate of as much as 140 m³/h and a delivery head of up to eighty two m are potential. The suction cover mounted on the pump housing can be used to regulate the cutting hole between the impeller and the damage plate with the assist of six set screws. “The energy of our new Alligator collection, which is out there for wet properly installation in addition to dry installation, is its nice effectivity and effective cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle costs thanks to wear-resistant design
In order to achieve not only the best possible efficiency values within the operating vary required for these sorts of wastewater functions, but in addition to scale back lifecycle costs general, HOMA attaches nice importance to low-maintenance operation along with effectivity. Improved and wear plate, which are the elements subject to essentially the most stress, are manufactured from extraordinarily sturdy chilled chrome forged iron, which withstands even abrasive substances corresponding to sand within the pumped medium. In addition, the hydraulics have been optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to extend efficiency and to get rid of any possibility of solids increase, which may negatively influence performance and lead to pricey 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 energy and maintenance costs because of their excessive effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water applications that require excessive supply strain, but on the similar time should cope with many different sorts of solids.”
HOMA will be presenting the model new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and other improvements, similar to the upkeep slide with sliding motor mount, shall be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
