New chopper pump achieves excessive efficiency without compromising on slicing efficiency

Problematic solids similar to sanitary towels, plastic bags, textiles and wood are being found increasingly often in wastewater. Pumping and sewage remedy vegetation are subsequently increasingly reaching their limits; items get clogged up and break down.
In times when low lifecycle costs are taking half in an ever extra essential role, HOMA Pumpenfabrik presents an power efficient and reliable solution for areas the place a high supply head is required, but at the identical time, a various range of solids is predicted: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator series allows effective operation via a powerful cutter system. Thanks to the usage of extremely sturdy chilled chrome forged iron, the main elements which are subject to the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA might be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs have gotten increasingly necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for vitality saving and dependable pumps that reach high supply heads with great efficiency.” With its new Alligator chopper pump collection, which may also be obtainable as an explosion-proof version, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with high efficiency
“Our objective was to realize excessive supply pressures within the medium flow fee vary,” reviews Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and more vitality saving motor than in different pumps in the identical working range was enough. To achieve this, HOMA developed a model new cutter system that successfully shreds and removes massive quantities of diverse solids such as tear-resistant hygiene wipes, plastic luggage and wood, 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 also be geared up with its personal cutter. This design allows the two central parts to work collectively to catch solids, break them down and finally remove them from the suction space by way of integrated grooves within the wear plate.
To enable larger effectivity without compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a outcome, within the 50 Hz version, a circulate price of as much as 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 flow rate of up to 140 m³/h and a supply head of as much as 82 m are potential. The suction cowl mounted on the pump housing can be used to adjust the chopping gap between the impeller and the wear and tear plate with the assist of six set screws. “The energy of our new Alligator series, which is out there for wet nicely installation in addition to dry set up, is its great efficiency and efficient cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
spmk700 to wear-resistant design
In order to achieve not solely the very best effectivity values within the working vary required for these sorts of wastewater functions, but also to reduce lifecycle costs general, HOMA attaches great importance to low-maintenance operation along with efficiency. The impeller and put on plate, that are the components topic to essentially the most stress, are made from extremely durable chilled chrome forged iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics were optimally designed for the operating range using computational fluid dynamics (CFD) to extend efficiency and to get rid of any possibility of solids increase, which may negatively impact efficiency and lead to costly 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 power and maintenance costs because of their high efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water functions that require excessive delivery strain, but on the same time should take care of many alternative kinds of solids.”
HOMA shall be presenting the model new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and other improvements, corresponding to the maintenance slide with sliding motor mount, might be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
