Problematic solids similar to sanitary towels, plastic baggage, textiles and wooden are being discovered increasingly more typically in wastewater. Pumping and sewage therapy plants are therefore more and more reaching their limits; units get clogged up and break down.
In occasions when low lifecycle prices are playing an ever extra necessary position, HOMA Pumpenfabrik presents an power efficient and reliable resolution for areas the place a high delivery head is required, but at the same time, a various vary of solids is anticipated: the Alligator chopper pump series. The newly developed OC impeller of the Alligator series enables effective operation by way of a strong cutter system. Thanks to using highly sturdy chilled chrome cast iron, the primary elements which are subject to the most stress perform reliably even with abrasive substances similar to sand. HOMA shall be presenting the brand new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle prices have gotten more and more essential in water and wastewater functions,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for power saving and dependable pumps that attain excessive supply heads with nice efficiency.” With its new Alligator chopper pump collection, which may also be out there as an explosion-proof version, HOMA has developed a very environment friendly response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our aim was to attain high delivery pressures in the medium circulate fee range,” reviews Konstantin Pörsch. Without forfeiting pump fee, the improved efficiency meant that a smaller, cheaper and more energy saving motor than in different pumps in the identical working range was enough. To obtain this, HOMA developed a brand new cutter system that successfully shreds and removes large portions of various solids similar to tear-resistant hygiene wipes, plastic baggage and wooden, which also get into the wastewater via surface water. The specially designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which can be equipped with its personal cutter. This design permits the 2 central elements to work collectively to catch solids, break them down and in the end take away them from the suction space via built-in grooves in the put on plate.
To allow เกจวัดแรงดันน้ำ10บาร์ with out compromising on slicing performance, the blades of the impeller also curve strongly backwards. As a end result, within the 50 Hz version, a circulate rate of up to one hundred thirty m³/h and a supply head of as much as 57 m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of eight to twenty kW, a flow rate of up to 140 m³/h and a delivery head of as much as 82 m are attainable. The suction cowl mounted on the pump housing may also be used to adjust the cutting gap between the impeller and the put on and tear plate with the assist of six set screws. “The energy of our new Alligator series, which is on the market for moist nicely set up in addition to dry set up, is its nice efficiency and effective cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to achieve not solely the absolute best efficiency values within the working vary required for these kinds of wastewater purposes, but additionally to scale back lifecycle costs overall, HOMA attaches nice significance to low-maintenance operation in addition to effectivity. The impeller and put on plate, which are the components subject to probably the most stress, are made of extraordinarily durable chilled chrome forged iron, which withstands even abrasive substances similar to sand in the pumped medium. In addition, the hydraulics were optimally designed for the working range utilizing computational fluid dynamics (CFD) to increase efficiency and to eliminate any possibility of solids increase, which can negatively impact efficiency and lead to costly pump failures. “With the newly developed cutter system, the Alligator pumps can successfully break down all solids within the waste water and transport them away, saving both power and maintenance prices thanks to their high efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly suitable for waste water functions that require excessive delivery stress, however on the identical time have to cope with many various sorts of solids.”
HOMA will be presenting the new Alligator chopper pump sequence for the first time at IFAT 2022 in Munich. This and different innovations, similar to the maintenance slide with sliding motor mount, will be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
