New chopper pump achieves excessive effectivity without compromising on chopping performance

Problematic solids corresponding to sanitary towels, plastic bags, textiles and wooden are being found increasingly more often in wastewater. Pumping and sewage remedy crops are due to this fact more and more reaching their limits; items get clogged up and break down.
In times when low lifecycle costs are enjoying an ever more necessary function, HOMA Pumpenfabrik offers an vitality environment friendly and reliable resolution for areas where a excessive delivery head is required, however at the identical time, a diverse vary of solids is predicted: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator collection permits effective operation by way of a strong cutter system. Thanks to using highly durable chilled chrome forged iron, the main parts that are topic to the most stress carry out reliably even with abrasive substances such as sand. HOMA shall be presenting the brand new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle prices have gotten more and more 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 power saving and reliable pumps that reach excessive delivery heads with nice efficiency.” With its new Alligator chopper pump series, which will also be obtainable as an explosion-proof version, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with high efficiency
“Our aim was to realize high supply pressures within the medium circulate price range,” reports Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and extra vitality saving motor than in different pumps in the identical working range was enough. To achieve this, HOMA developed a new cutter system that successfully shreds and removes massive quantities of numerous solids similar to tear-resistant hygiene wipes, plastic baggage and wooden, which also get into the wastewater through floor 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 outfitted with its personal cutter. This design allows the two central elements to work collectively to catch solids, break them down and finally take away them from the suction space via built-in grooves in the wear plate.
To enable higher efficiency without compromising on chopping efficiency, the blades of the impeller additionally curve strongly backwards. As a result, within the 50 Hz model, a circulate fee of up to one hundred thirty m³/h and a delivery head of as much as fifty seven m can be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of eight to 20 kW, a circulate fee of up to 140 m³/h and a supply head of up to eighty two m are possible. pressure gauge digital ราคา mounted on the pump housing can also be used to regulate the chopping hole between the impeller and the damage plate with assistance from six set screws. “The power of our new Alligator sequence, which is out there for moist properly set up as well as dry installation, is its great efficiency and effective cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to realize not only the very best effectivity values within the operating range required for these kinds of wastewater purposes, but additionally to scale back lifecycle costs general, HOMA attaches great significance to low-maintenance operation along with efficiency. The impeller and put on plate, which are the parts topic to probably the most stress, are made from extremely sturdy chilled chrome cast iron, which withstands even abrasive substances such as sand within the pumped medium. In addition, the hydraulics have been optimally designed for the operating vary using computational fluid dynamics (CFD) to extend efficiency and to get rid of any risk of solids build up, which may negatively impact performance and result in expensive 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 each energy and maintenance costs because of their high effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water functions that require excessive supply pressure, but at the identical time need to cope with many different kinds of solids.”
HOMA will be presenting the new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and different innovations, similar to the upkeep slide with sliding motor mount, might be explained and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
