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

Problematic solids similar to sanitary towels, plastic baggage, textiles and wood are being found increasingly typically in wastewater. Pumping and sewage therapy plants are therefore increasingly reaching their limits; items get clogged up and break down.
In instances when low lifecycle prices are playing an ever more essential position, HOMA Pumpenfabrik offers an power efficient and dependable answer for areas where a excessive delivery head is required, but at the same time, a various range of solids is expected: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator series permits efficient operation through a robust cutter system. Thanks to the use of extremely sturdy chilled chrome forged iron, the main elements that are subject to essentially the most stress perform 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 potential lifecycle prices have gotten increasingly essential in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for power saving and dependable pumps that reach excessive supply heads with great efficiency.” With its new Alligator chopper pump sequence, which may also be available as an explosion-proof version, HOMA has developed a particularly efficient response to this demand.

“Our aim was to realize high delivery pressures within the medium circulate price vary,” reports Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and more vitality saving motor than in other pumps in the identical operating vary was adequate. To obtain this, HOMA developed a new cutter system that effectively shreds and removes giant portions of diverse solids similar to tear-resistant hygiene wipes, plastic luggage and wood, which additionally get into the wastewater through surface water. The specially designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which can be outfitted with its personal cutter. This design allows the 2 central parts to work collectively to catch solids, break them down and ultimately remove them from the suction area by way of built-in grooves in the wear plate.
To allow greater effectivity without compromising on slicing efficiency, the blades of the impeller also curve strongly backwards. As a end result, within the 50 Hz model, a circulate price of up to a hundred thirty m³/h and a delivery head of up to 57 m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of 8 to twenty kW, a circulate rate of up to 140 m³/h and a supply head of up to 82 m are potential. The suction cowl mounted on the pump housing may additionally be used to regulate the chopping hole between the impeller and the damage plate with the assist of six set screws. “The energy of our new Alligator sequence, which is available for moist well installation as properly as dry set up, is its nice effectivity and efficient cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to attain not only the finest possible efficiency values within the working vary required for these kinds of wastewater functions, but also to reduce lifecycle prices general, HOMA attaches nice importance to low-maintenance operation along with efficiency. The impeller and put on plate, which are the components subject to probably the most stress, are made from extremely durable chilled chrome forged iron, which withstands even abrasive substances corresponding to sand within the pumped medium. In addition, the hydraulics were optimally designed for the operating range using computational fluid dynamics (CFD) to increase effectivity and to remove any possibility of solids increase, which may negatively impact performance and result in expensive pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids in the waste water and transport them away, saving each vitality and upkeep costs due to their excessive efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly suitable for waste water purposes that require high delivery strain, but on the similar time have to take care of many different sorts of solids.”
HOMA will be presenting the new Alligator chopper pump series for the primary time at IFAT 2022 in Munich. This and other innovations, corresponding to the upkeep slide with sliding motor mount, might be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
