Problematic solids such as sanitary towels, plastic baggage, textiles and wood are being discovered more and more often in wastewater. Pumping and sewage treatment vegetation are subsequently increasingly reaching their limits; items get clogged up and break down.
In occasions when low lifecycle prices are enjoying an ever more essential function, HOMA Pumpenfabrik offers an vitality efficient and reliable answer for areas the place a excessive supply head is required, however at the same time, a various range of solids is anticipated: 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 highly sturdy chilled chrome cast iron, the primary components that are subject to essentially the most stress carry out reliably even with abrasive substances such as sand. HOMA might be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest possible lifecycle prices have gotten increasingly essential 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 energy saving and dependable pumps that reach high supply heads with nice effectivity.” With its new Alligator chopper pump collection, which may also be obtainable as an explosion-proof model, HOMA has developed a very environment friendly response to this demand.
Cutter system shreds all solids with high efficiency
“Our objective was to attain excessive supply pressures in the medium move price range,” stories Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and extra power saving motor than in different pumps in the same operating vary was sufficient. To achieve this, HOMA developed a new cutter system that successfully shreds and removes large portions of various solids similar to tear-resistant hygiene wipes, plastic baggage and wood, which additionally get into the wastewater via surface water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which is also geared up with its own cutter. This design allows the two central elements to work together to catch solids, break them down and ultimately remove them from the suction space by way of built-in grooves within the put on plate.
To enable เครื่องมือที่ใช้วัดความดันเลือด without compromising on chopping efficiency, the blades of the impeller also curve strongly backwards. As a result, within the 50 Hz version, a flow fee of up to one hundred thirty m³/h and a supply head of up to fifty seven m can be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of 8 to 20 kW, a move rate of as much as one hundred forty m³/h and a supply head of up to 82 m are possible. The suction cowl mounted on the pump housing can be used to adjust the slicing gap between the impeller and the wear and tear plate with the assist of six set screws. “The energy of our new Alligator collection, which is on the market for wet well installation in addition to dry set up, is its nice effectivity and effective cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design
In order to attain not solely the very best effectivity values in the operating vary required for these kinds of wastewater applications, but also to scale back lifecycle costs overall, HOMA attaches nice significance to low-maintenance operation in addition to effectivity. The impeller and put on plate, that are the components subject to probably the most stress, are made from extraordinarily durable chilled chrome forged iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics had been optimally designed for the working range using computational fluid dynamics (CFD) to increase effectivity and to get rid of any risk of solids increase, 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 prices due to their excessive efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them notably appropriate for waste water applications that require excessive delivery stress, however on the same time should cope with many various sorts of solids.”
HOMA will be presenting the brand new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and other innovations, corresponding to 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.
