Problematic solids similar to sanitary towels, plastic bags, textiles and wood are being discovered more and more typically in wastewater. Pumping and sewage therapy vegetation are therefore increasingly reaching their limits; items get clogged up and break down.
In instances when low lifecycle costs are taking half in an ever more important role, HOMA Pumpenfabrik offers an vitality environment friendly and reliable resolution for areas where a high supply head is required, however at the same time, a various range of solids is anticipated: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection enables effective operation via a strong cutter system. Thanks to using extremely durable chilled chrome forged iron, the primary components which may be subject to probably 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.
“The lowest attainable lifecycle prices are becoming increasingly important 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 power saving and reliable pumps that reach excessive delivery heads with nice effectivity.” With its new Alligator chopper pump sequence, which will also be available as an explosion-proof version, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our objective was to realize excessive supply pressures in the medium circulate price range,” reports Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and extra power saving motor than in different pumps in the same working range was enough. To achieve this, HOMA developed a new cutter system that effectively shreds and removes massive quantities of numerous solids such as tear-resistant hygiene wipes, plastic bags and wood, which also get into the wastewater through surface water. เกจวัดแรงดันออกซิเจนราคา designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear and tear plate, which is also equipped with its own 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 by way of integrated grooves within the wear plate.
To allow higher efficiency with out compromising on chopping efficiency, the blades of the impeller also curve strongly backwards. As a end result, in the 50 Hz model, a flow rate of up to a hundred thirty m³/h and a delivery head of up to fifty seven 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 circulate price of as a lot as a hundred and forty m³/h and a delivery head of up to eighty two m are possible. The suction cowl mounted on the pump housing can be used to adjust the chopping hole between the impeller and the put on 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 set up in addition to dry installation, is its great effectivity and efficient cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to achieve not only the absolute best efficiency values within the operating range required for these sorts of wastewater functions, but also to reduce lifecycle prices total, HOMA attaches nice importance to low-maintenance operation in addition to efficiency. The impeller and wear plate, which are the components topic to the most stress, are manufactured from extremely durable chilled chrome forged iron, which withstands even abrasive substances similar to sand within the pumped medium. In addition, the hydraulics were optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to extend effectivity and to get rid of any chance of solids build up, which may negatively impression efficiency and result in expensive 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 each power and maintenance prices thanks to their high efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water functions that require high supply strain, but at the similar time need to take care of many different sorts of solids.”
HOMA might be presenting the model new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and different improvements, corresponding to the upkeep slide with sliding motor mount, shall be explained and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
