Problematic solids such as sanitary towels, plastic baggage, textiles and wooden are being found more and more typically in wastewater. Pumping and sewage therapy crops are due to this fact increasingly reaching their limits; items get clogged up and break down.
In instances when low lifecycle costs are playing an ever extra essential position, HOMA Pumpenfabrik presents an vitality environment friendly and dependable solution for areas where a excessive supply head is required, but at the similar time, a various range of solids is anticipated: the Alligator chopper pump series. The newly developed OC impeller of the Alligator series allows efficient operation by way of a robust cutter system. Thanks to the use of extremely durable chilled chrome cast iron, the primary elements which are subject to essentially the most stress perform reliably even with abrasive substances corresponding to sand. HOMA will be presenting เกจวัดแรงดันpsi for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle prices are becoming increasingly necessary in water and wastewater functions,” 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 attain excessive delivery heads with great effectivity.” With its new Alligator chopper pump series, which will also be available as an explosion-proof model, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with high efficiency
“Our aim was to achieve excessive supply pressures in the medium move rate range,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and extra energy saving motor than in different pumps in the same working range was adequate. To achieve this, HOMA developed a new cutter system that successfully shreds and removes massive portions of diverse solids similar to tear-resistant hygiene wipes, plastic luggage and wood, which additionally get into the wastewater via floor water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which can additionally be geared up with its personal cutter. This design allows the two central components to work together to catch solids, break them down and in the end remove them from the suction area through built-in grooves in the put on plate.
To enable higher effectivity without compromising on slicing efficiency, the blades of the impeller additionally curve strongly backwards. As a result, in the 50 Hz model, a move rate of up to a hundred thirty m³/h and a supply head of as much as fifty seven m can be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of eight to 20 kW, a move price of as much as 140 m³/h and a supply head of up to 82 m are possible. The suction cover mounted on the pump housing can be used to adjust the slicing gap between the impeller and the put on and tear plate with assistance from six set screws. “The power of our new Alligator series, which is out there for moist well set up as properly as dry set up, is its nice efficiency and effective cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to achieve not only the very best effectivity values in the working range required for these kinds of wastewater applications, but also to minimize back lifecycle costs total, HOMA attaches great importance to low-maintenance operation in addition to effectivity. The impeller and wear plate, which are the parts topic to the most stress, are manufactured from extremely sturdy chilled chrome cast iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics were optimally designed for the operating vary using computational fluid dynamics (CFD) to increase effectivity and to remove any chance of solids build up, which can negatively influence performance and lead to 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 both energy and maintenance prices due to their excessive effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water functions that require high delivery stress, but on the similar time need to deal with many different kinds of solids.”
HOMA might be presenting the brand new Alligator chopper pump sequence for the first time at IFAT 2022 in Munich. This and different innovations, corresponding to the maintenance slide with sliding motor mount, might be defined and demonstrated by the HOMA gross sales staff in Hall B1 at Stand 429/528.
