Problematic solids similar to sanitary towels, plastic bags, textiles and wood are being found increasingly often in wastewater. Pumping and sewage therapy plants are due to this fact increasingly reaching their limits; items get clogged up and break down.
In instances when low lifecycle prices are enjoying an ever more necessary position, HOMA Pumpenfabrik offers an power environment friendly and reliable answer for areas the place a high delivery head is required, but on the same time, a diverse range of solids is expected: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection permits efficient operation through a powerful cutter system. Thanks to the usage of extremely sturdy chilled chrome forged iron, the primary elements which are topic to probably the most stress perform reliably even with abrasive substances such as sand. HOMA might be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest attainable lifecycle prices are becoming more and more essential in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for energy saving and reliable pumps that reach high delivery heads with nice efficiency.” With its new Alligator chopper pump collection, which will also be out there as an explosion-proof model, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with high efficiency
“Our aim was to realize high delivery pressures in the medium circulate rate range,” stories Konstantin Pörsch. Without forfeiting pump fee, the improved efficiency meant that a smaller, cheaper and more vitality saving motor than in other pumps in the identical operating range was adequate. To achieve this, HOMA developed a brand new cutter system that effectively shreds and removes massive portions of diverse solids similar to tear-resistant hygiene wipes, plastic bags and wood, which additionally get into the wastewater by way of surface water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear and tear plate, which is also geared up with its own cutter. เกจวัดแก๊สlpg permits 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 effectivity with out compromising on slicing performance, the blades of the impeller also curve strongly backwards. As a end result, in the 50 Hz version, a circulate rate of as a lot as a hundred thirty m³/h and a supply head of as a lot as fifty seven m may be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of eight to 20 kW, a move price of up to one hundred forty m³/h and a supply head of up to 82 m are potential. The suction cover mounted on the pump housing can also be used to adjust the cutting gap between the impeller and the wear and tear plate with assistance from six set screws. “The energy of our new Alligator sequence, which is available for moist well installation as nicely as dry installation, is its great efficiency and efficient cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to attain not only the greatest possible efficiency values within the working range required for these kinds of wastewater applications, but additionally to reduce lifecycle prices overall, HOMA attaches nice importance to low-maintenance operation in addition to efficiency. The impeller and wear plate, that are the components subject to probably the most stress, are made from extremely durable chilled chrome forged iron, which withstands even abrasive substances such as sand within the pumped medium. In addition, the hydraulics have been optimally designed for the working vary utilizing computational fluid dynamics (CFD) to extend efficiency and to eliminate any possibility of solids build up, which can negatively influence efficiency and result in costly 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 upkeep prices due to their high effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water functions that require excessive delivery pressure, however on the same time should deal with many different kinds of solids.”
HOMA shall be presenting the new Alligator chopper pump collection for the first time at IFAT 2022 in Munich. This and different innovations, similar to the maintenance slide with sliding motor mount, will be explained and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
