New chopper pump achieves high effectivity without compromising on chopping performance

Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wooden are being found increasingly usually in wastewater. Pumping and sewage remedy plants are therefore more and more reaching their limits; units get clogged up and break down.
In times when low lifecycle costs are taking part in an ever more necessary position, HOMA Pumpenfabrik offers an power efficient and dependable answer for areas the place a high delivery head is required, however on the similar time, a various vary of solids is predicted: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator collection enables effective operation through a strong cutter system. Thanks to the usage of extremely sturdy chilled chrome forged iron, the primary elements which are topic to the most stress perform reliably even with abrasive substances such as sand. HOMA might be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs have gotten increasingly essential in water and wastewater applications,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for power saving and dependable pumps that reach excessive delivery heads with nice efficiency.” With its new Alligator chopper pump collection, which may even 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 aim was to achieve excessive supply pressures within the medium circulate fee range,” stories Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and more vitality saving motor than in other pumps in the identical working range was enough. To achieve this, HOMA developed a model new cutter system that successfully shreds and removes massive quantities of diverse solids such as tear-resistant hygiene wipes, plastic luggage and wooden, which also get into the wastewater by way of surface water. The specially 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 2 central components to work collectively to catch solids, break them down and finally take away them from the suction space via integrated grooves in the put on plate.
To allow larger effectivity without compromising on cutting efficiency, the blades of the impeller additionally curve strongly backwards. As a outcome, within the 50 Hz version, a move price of as much as one hundred thirty m³/h and a delivery head of up to fifty seven m could be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of eight to 20 kW, a circulate price of as much as 140 m³/h and a supply head of up to 82 m are attainable. เกจวัดความดันน้ำ mounted on the pump housing can additionally be used to adjust the cutting gap between the impeller and the wear plate with assistance from six set screws. “The power of our new Alligator collection, which is on the market for wet well set up as nicely as dry set up, is its great efficiency and efficient cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle prices due to wear-resistant design
In order to attain not solely the very best efficiency values within the working vary required for these sorts of wastewater applications, but in addition to reduce lifecycle costs general, HOMA attaches great importance to low-maintenance operation along with effectivity. The impeller and wear plate, which are the parts subject to essentially the most stress, are made of extraordinarily sturdy chilled chrome forged iron, which withstands even abrasive substances similar to sand in the pumped medium. In addition, the hydraulics were optimally designed for the working vary using computational fluid dynamics (CFD) to increase efficiency and to remove any risk of solids building up, which can negatively influence performance and result in expensive 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 vitality and maintenance costs because of their high effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water functions that require excessive supply strain, however at the identical time have to take care of many alternative sorts of solids.”
HOMA shall be presenting the new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and other improvements, corresponding to the maintenance slide with sliding motor mount, will be defined and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
