Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wood are being found more and more typically in wastewater. Pumping and sewage therapy crops are due to this fact increasingly reaching their limits; models get clogged up and break down.
In occasions when low lifecycle costs are enjoying an ever extra important role, HOMA Pumpenfabrik provides an power efficient and reliable resolution for areas the place a excessive delivery head is required, but on the same time, a various range of solids is anticipated: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator collection allows effective operation by way of a robust cutter system. Thanks to the utilization of extremely sturdy chilled chrome forged iron, the principle components which would possibly be topic to probably the most stress carry out reliably even with abrasive substances such as sand. HOMA will be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs are becoming more and more necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and reliable pumps that attain high supply heads with nice effectivity.” With its new Alligator chopper pump collection, which may even 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 efficiency
“Our objective was to realize high delivery pressures within the medium circulate rate range,” stories Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and extra vitality saving motor than in other pumps in the same operating vary was sufficient. To obtain this, HOMA developed a new cutter system that effectively shreds and removes massive quantities of various solids corresponding to tear-resistant hygiene wipes, plastic bags and wooden, which also get into the wastewater through surface water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the wear plate, which can also be outfitted with its own cutter. This design permits the two central elements to work together to catch solids, break them down and finally take away them from the suction area through built-in grooves in the wear plate.
To allow greater efficiency with out compromising on chopping performance, the blades of the impeller additionally curve strongly backwards. As a end result, within the 50 Hz version, a circulate rate of as much as a hundred thirty m³/h and a supply head of as a lot as fifty seven m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of eight to twenty kW, a flow price of as much as one hundred forty m³/h and a supply head of up to eighty two m are possible. The suction cover mounted on the pump housing may additionally be used to adjust the slicing gap between the impeller and the damage plate with the aid of six set screws. “The strength of our new Alligator series, which is available for moist nicely set up as nicely as dry installation, is its great efficiency and effective cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle prices due to wear-resistant design
In order to realize not solely the finest possible effectivity values in the operating vary required for these kinds of wastewater applications, but additionally to scale back lifecycle prices total, HOMA attaches great significance to low-maintenance operation in addition to efficiency. The impeller and put on plate, that are the elements subject to essentially the most stress, are manufactured from extremely sturdy chilled chrome cast iron, which withstands even abrasive substances such as sand within the pumped medium. In addition, the hydraulics were optimally designed for the operating vary using computational fluid dynamics (CFD) to increase efficiency and to remove any possibility of solids build up, which might negatively impact efficiency and result in 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 energy and upkeep costs thanks to their excessive effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly suitable for waste water functions that require excessive supply strain, however on the similar time need to cope with many alternative kinds of solids.”
HOMA shall be presenting ตัววัดแรงดันน้ำมัน for the primary time at IFAT 2022 in Munich. This and other innovations, such as the upkeep slide with sliding motor mount, will be defined and demonstrated by the HOMA gross sales staff in Hall B1 at Stand 429/528.
