New chopper pump achieves high effectivity without compromising on cutting performance

เกจวัดแรงดันราคา as sanitary towels, plastic luggage, textiles and wood are being found increasingly often in wastewater. Pumping and sewage remedy plants are subsequently increasingly reaching their limits; items get clogged up and break down.
In occasions when low lifecycle costs are enjoying an ever extra necessary position, HOMA Pumpenfabrik offers an power efficient and reliable resolution for areas where a high delivery head is required, however on the similar time, a diverse vary of solids is expected: the Alligator chopper pump series. The newly developed OC impeller of the Alligator sequence enables efficient operation via a powerful cutter system. Thanks to the use of highly sturdy chilled chrome forged iron, the principle components which may be topic to probably the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA will be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs are becoming more and more necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and dependable pumps that attain high supply heads with nice effectivity.” 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 high effectivity
“Our goal was to attain high delivery pressures in the medium circulate rate range,” stories Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and more energy saving motor than in different pumps in the identical operating range was enough. To achieve this, HOMA developed a new cutter system that successfully shreds and removes giant portions of various solids such as 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 wear plate, which is also geared up with its own cutter. This design allows the 2 central parts to work together to catch solids, break them down and finally remove them from the suction space through integrated grooves in the wear plate.
To enable greater efficiency without compromising on cutting efficiency, the blades of the impeller additionally curve strongly backwards. As a end result, within the 50 Hz model, a move fee of as much as 130 m³/h and a delivery head of up to 57 m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of eight to 20 kW, a move price of up to one hundred forty m³/h and a delivery head of up to 82 m are possible. The suction cover mounted on the pump housing may additionally be used to adjust the cutting hole between the impeller and the damage plate with the help of six set screws. “The strength of our new Alligator series, which is out there for wet well installation as properly as dry installation, is its nice effectivity and efficient cutter system, coupled with an extended service life,” adds Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design
In order to realize not solely the greatest possible effectivity values in the operating vary required for these kinds of wastewater applications, but additionally to scale back lifecycle costs overall, HOMA attaches nice importance to low-maintenance operation along with efficiency. The impeller and put on plate, which are the components subject to probably the most stress, are manufactured from extraordinarily durable chilled chrome cast iron, which withstands even abrasive substances such as sand within the pumped medium. In addition, the hydraulics have been optimally designed for the operating vary utilizing computational fluid dynamics (CFD) to increase effectivity and to get rid of any chance of solids increase, which can negatively impact performance and result in pricey pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids within the waste water and transport them away, saving both power and maintenance prices because of their high efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water functions that require high delivery strain, however on the identical time need to take care of many various sorts of solids.”
HOMA will be presenting the new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and different improvements, such as the maintenance slide with sliding motor mount, shall be explained and demonstrated by the HOMA gross sales staff in Hall B1 at Stand 429/528.
