Problematic solids similar to sanitary towels, plastic luggage, textiles and wood are being found increasingly more usually in wastewater. Pumping and sewage therapy plants are therefore increasingly reaching their limits; items get clogged up and break down.
In instances when low lifecycle prices are taking part in an ever extra essential role, HOMA Pumpenfabrik offers an power efficient and dependable answer for areas the place a excessive delivery head is required, but on the identical time, a various vary of solids is expected: the Alligator chopper pump collection. compound gauge ราคา developed OC impeller of the Alligator collection enables effective operation via a strong cutter system. Thanks to the usage of extremely sturdy chilled chrome cast iron, the main parts that are topic to the most stress carry out reliably even with abrasive substances similar to sand. HOMA shall be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest attainable lifecycle prices are becoming more and more important in water and wastewater applications,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for energy saving and dependable pumps that reach excessive supply heads with great effectivity.” With its new Alligator chopper pump series, which may even be out there as an explosion-proof model, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with high efficiency
“Our aim was to achieve high supply pressures in the medium flow rate vary,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and extra energy saving motor than in different pumps in the same operating vary was sufficient. To achieve this, HOMA developed a brand new cutter system that successfully shreds and removes giant portions of various solids corresponding to tear-resistant hygiene wipes, plastic baggage and wooden, which also get into the wastewater via surface water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the damage plate, which is also equipped with its personal cutter. This design allows the two central components to work collectively to catch solids, break them down and in the end remove them from the suction space via integrated grooves in the wear plate.
To allow greater efficiency with out compromising on cutting efficiency, the blades of the impeller additionally curve strongly backwards. As a outcome, in the 50 Hz version, a move price of up to 130 m³/h and a delivery head of up to fifty seven m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of 8 to 20 kW, a flow rate of as much as one hundred forty m³/h and a delivery head of up to 82 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 help of six set screws. “The strength of our new Alligator collection, which is on the market for moist nicely installation as properly as dry installation, is its nice effectivity and effective cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to realize not solely the finest possible effectivity values in the working range required for these sorts of wastewater functions, but in addition to scale back lifecycle prices general, HOMA attaches nice significance to low-maintenance operation in addition to efficiency. The impeller and put on plate, that are the components topic to essentially the most stress, are made from extraordinarily sturdy chilled chrome cast iron, which withstands even abrasive substances similar to sand in the pumped medium. In addition, the hydraulics have been optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to extend effectivity and to get rid of any possibility of solids increase, which may negatively influence performance and lead to 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 each vitality and maintenance prices thanks to their high efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water functions that require high supply strain, but at the similar time have to deal with many various sorts of solids.”
HOMA will be presenting the brand new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and other improvements, such as 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.
