New chopper pump achieves excessive efficiency with out compromising on chopping efficiency

Problematic solids such as sanitary towels, plastic bags, textiles and wood are being discovered increasingly usually in wastewater. Pumping and sewage treatment vegetation are subsequently increasingly reaching their limits; units get clogged up and break down.
In instances when low lifecycle prices are enjoying an ever extra important position, HOMA Pumpenfabrik provides an energy efficient and dependable resolution for areas the place a high delivery head is required, however on the same time, a various vary of solids is predicted: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator collection permits efficient operation via a powerful cutter system. Thanks to using highly durable chilled chrome cast iron, the main parts which might be topic to the most stress perform reliably even with abrasive substances such as sand. HOMA will be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
เกจวัดแรงดันแก๊สlpg have gotten increasingly necessary in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for vitality saving and reliable pumps that reach excessive supply 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 particularly environment friendly response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our aim was to realize excessive delivery pressures in the medium move rate vary,” stories Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and extra vitality saving motor than in different pumps in the same working vary was adequate. To obtain this, HOMA developed a new cutter system that successfully shreds and removes large portions of diverse solids such as tear-resistant hygiene wipes, plastic baggage and wooden, which additionally get into the wastewater by way of floor water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear plate, which is also equipped with its own cutter. This design allows the 2 central elements to work together to catch solids, break them down and in the end take away them from the suction area by way of integrated grooves in the put on plate.
To allow greater effectivity with out compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a outcome, in the 50 Hz model, a move fee of up to a hundred thirty m³/h and a supply head of up to fifty seven m can be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of 8 to 20 kW, a circulate rate of up to 140 m³/h and a supply head of as a lot as 82 m are possible. The suction cover mounted on the pump housing can additionally be used to adjust the cutting gap between the impeller and the wear plate with the assist of six set screws. “The power of our new Alligator sequence, which is on the market for wet nicely set up as properly as dry installation, is its nice efficiency and efficient cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to realize not solely the absolute best effectivity values within the operating range required for these sorts of wastewater applications, but additionally to scale back lifecycle prices overall, HOMA attaches nice significance to low-maintenance operation along with efficiency. The impeller and put on plate, which are the parts topic to the most stress, are made of extremely durable chilled chrome cast iron, which withstands even abrasive substances corresponding to sand within the pumped medium. In addition, the hydraulics have been optimally designed for the working range using computational fluid dynamics (CFD) to extend effectivity and to remove any possibility of solids build up, which might negatively impact performance and result in 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 energy and upkeep costs due to their excessive efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly suitable for waste water applications that require excessive delivery pressure, but on the similar time need to take care of many different kinds of solids.”
HOMA might be presenting the new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and different improvements, such as the maintenance slide with sliding motor mount, shall be defined and demonstrated by the HOMA sales group in Hall B1 at Stand 429/528.
