เกจ์แรงดัน to sanitary towels, plastic baggage, textiles and wooden are being found increasingly often in wastewater. Pumping and sewage remedy plants are therefore more and more reaching their limits; items get clogged up and break down.
In occasions when low lifecycle prices are taking part in an ever extra important position, HOMA Pumpenfabrik offers an energy efficient and dependable answer for areas the place a excessive supply head is required, but on the identical time, a diverse vary of solids is expected: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator sequence permits effective operation by way of a strong cutter system. Thanks to the utilization of extremely sturdy chilled chrome cast iron, the primary elements which might be topic to essentially the most stress perform reliably even with abrasive substances corresponding to sand. HOMA might be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest potential lifecycle prices are becoming increasingly necessary in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for energy saving and reliable pumps that reach excessive delivery heads with great efficiency.” With its new Alligator chopper pump sequence, which will also be obtainable as an explosion-proof version, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with high effectivity
“Our objective was to achieve high supply pressures in the medium circulate price vary,” stories Konstantin Pörsch. Without forfeiting pump rate, the improved effectivity meant that a smaller, cheaper and more vitality saving motor than in other pumps in the identical working range was sufficient. To obtain this, HOMA developed a brand new cutter system that effectively shreds and removes large quantities of numerous solids such as tear-resistant hygiene wipes, plastic luggage and wood, which additionally get into the wastewater by way of surface water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear and tear plate, which can be outfitted with its personal cutter. This design permits the 2 central elements to work together to catch solids, break them down and ultimately take away them from the suction area by way of built-in grooves in the put on plate.
To enable greater efficiency with out compromising on chopping performance, the blades of the impeller also curve strongly backwards. As a end result, within the 50 Hz model, a move fee of as much as 130 m³/h and a supply head of up to 57 m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of 8 to twenty kW, a flow price of up to one hundred forty m³/h and a delivery head of up to 82 m are possible. The suction cover mounted on the pump housing may additionally be used to regulate the cutting gap between the impeller and the wear plate with the assist of six set screws. “The energy of our new Alligator series, which is out there for wet properly installation as properly as dry set up, is its great efficiency and effective cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to achieve not only the absolute best efficiency values in the operating range required for these sorts of wastewater applications, but in addition to cut back lifecycle prices general, HOMA attaches nice significance to low-maintenance operation along with efficiency. The impeller and wear plate, that are the parts subject to probably the most stress, are made of extraordinarily 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 effectivity and to get rid of any possibility of solids build up, which might negatively influence efficiency and lead to costly pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids within the waste water and transport them away, saving each energy and maintenance prices because of their excessive effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly suitable for waste water purposes that require excessive supply pressure, but on the identical time should take care of many alternative kinds of solids.”
HOMA might be presenting the new Alligator chopper pump sequence for the first time at IFAT 2022 in Munich. This and other improvements, such as the upkeep slide with sliding motor mount, might be explained and demonstrated by the HOMA gross sales staff in Hall B1 at Stand 429/528.
