New chopper pump achieves excessive effectivity with out compromising on cutting performance

Problematic solids corresponding to sanitary towels, plastic bags, textiles and wooden are being discovered increasingly more often in wastewater. Pumping and pressure gauge ไท วัสดุ are therefore increasingly reaching their limits; items get clogged up and break down.
In times when low lifecycle prices are taking half in an ever more necessary function, HOMA Pumpenfabrik provides an vitality efficient and reliable solution for areas the place a high delivery head is required, but on the similar time, a diverse vary of solids is anticipated: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator series enables efficient operation via a robust cutter system. Thanks to the use of extremely sturdy chilled chrome forged iron, the primary parts which are subject to probably the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA shall be presenting the model new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle prices are becoming increasingly important in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for power saving and reliable pumps that reach excessive supply heads with great efficiency.” With its new Alligator chopper pump sequence, which may even be out there as an explosion-proof model, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our aim was to realize high delivery pressures in the medium circulate price vary,” stories Konstantin Pörsch. Without forfeiting pump price, the improved efficiency meant that a smaller, cheaper and extra power saving motor than in other pumps in the identical operating vary was adequate. To obtain this, HOMA developed a brand new cutter system that effectively shreds and removes giant portions of diverse solids similar to tear-resistant hygiene wipes, plastic bags and wooden, which also get into the wastewater through surface water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which can additionally be equipped with its own cutter. This design allows the 2 central elements to work together to catch solids, break them down and in the end take away them from the suction space via built-in grooves in the put on plate.
To allow higher effectivity with out compromising on chopping efficiency, the blades of the impeller also curve strongly backwards. As a outcome, in the 50 Hz version, a move rate of up to 130 m³/h and a delivery head of as much as 57 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 circulate price of as much as 140 m³/h and a delivery head of up to eighty two m are attainable. The suction cover mounted on the pump housing may also be used to adjust the cutting gap between the impeller and the put on and tear plate with assistance from six set screws. “The power of our new Alligator series, which is available for wet properly installation in addition to dry installation, is its nice effectivity and effective cutter system, coupled with an extended service life,” provides Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design
In order to attain not solely the best possible effectivity values within the working vary required for these kinds of wastewater purposes, but also to reduce lifecycle prices total, HOMA attaches great importance to low-maintenance operation in addition to effectivity. The impeller and wear plate, that are the elements topic to the most stress, are manufactured from extraordinarily sturdy chilled chrome cast iron, which withstands even abrasive substances similar to sand in the pumped medium. In addition, the hydraulics were optimally designed for the working vary utilizing computational fluid dynamics (CFD) to increase efficiency and to remove any chance of solids build up, which can negatively impression efficiency and lead to 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 each energy and upkeep prices because of their excessive effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably suitable for waste water functions that require high supply stress, however at the identical time have to cope with many different sorts of solids.”
HOMA might be presenting the new Alligator chopper pump series for the first time at IFAT 2022 in Munich. This and other innovations, similar to the upkeep slide with sliding motor mount, will be defined and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
