Problematic solids such as sanitary towels, plastic luggage, textiles and wood are being discovered more and more 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 taking half in an ever extra important function, HOMA Pumpenfabrik provides an power efficient and reliable resolution for areas the place a high delivery head is required, but on the similar time, a various range of solids is expected: the Alligator chopper pump collection. เกจวัดแรงดัน developed OC impeller of the Alligator collection enables effective operation via a powerful cutter system. Thanks to using extremely sturdy chilled chrome forged iron, the main parts which are topic to essentially the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA might be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle prices are becoming increasingly essential in water and wastewater applications,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for energy saving and reliable pumps that attain high supply heads with great efficiency.” With its new Alligator chopper pump collection, which may even be out there as an explosion-proof model, HOMA has developed a very environment friendly response to this demand.
Cutter system shreds all solids with excessive effectivity

“Our aim was to achieve excessive supply pressures in the medium flow rate range,” reports Konstantin Pörsch. Without forfeiting pump fee, the improved efficiency meant that a smaller, cheaper and more power saving motor than in other pumps in the same working range was enough. To obtain this, HOMA developed a new cutter system that successfully shreds and removes giant quantities of various solids corresponding to tear-resistant hygiene wipes, plastic luggage and wooden, which additionally get into the wastewater through floor water. The specially designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the wear plate, which can be equipped with its own cutter. This design permits the 2 central parts to work together to catch solids, break them down and finally take away them from the suction area via built-in grooves within the put on plate.
To allow greater efficiency with out compromising on cutting efficiency, the blades of the impeller also curve strongly backwards. As a result, within the 50 Hz model, a circulate fee of up to one hundred thirty m³/h and a supply head of up to 57 m could be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of 8 to twenty kW, a flow fee of as a lot as a hundred and forty m³/h and a delivery head of up to 82 m are possible. The suction cover mounted on the pump housing can also be used to regulate the slicing gap between the impeller and the wear and tear plate with assistance from six set screws. “The strength of our new Alligator series, which is out there for wet properly set up as properly as dry set up, is its nice effectivity and efficient cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design

In order to achieve not only the absolute best effectivity values within the operating range required for these kinds of wastewater applications, but additionally to reduce lifecycle prices overall, HOMA attaches great significance to low-maintenance operation along with effectivity. The impeller and wear plate, which are the elements subject to essentially 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 were optimally designed for the operating range utilizing computational fluid dynamics (CFD) to increase efficiency and to get rid of any risk of solids building up, which might negatively influence performance and lead to 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 each vitality and upkeep costs because of their excessive effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them notably appropriate for waste water applications that require high delivery stress, however at the similar time need to take care of many different kinds of solids.”

HOMA shall be presenting the brand new Alligator chopper pump collection for the first time at IFAT 2022 in Munich. This and other innovations, such as the maintenance slide with sliding motor mount, will be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
