Problematic solids similar to sanitary towels, plastic luggage, textiles and wood are being discovered more and more often in wastewater. Pumping and sewage remedy vegetation are subsequently more and more reaching their limits; items get clogged up and break down.
In Economical when low lifecycle prices are taking half in an ever more essential role, HOMA Pumpenfabrik presents an energy efficient and dependable resolution for areas where a high supply head is required, however at the same time, a various vary of solids is predicted: the Alligator chopper pump series. The newly developed OC impeller of the Alligator collection enables effective operation via a robust cutter system. Thanks to using highly durable chilled chrome forged iron, the main elements which are topic to the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA might be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs are becoming increasingly essential in water and wastewater functions,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and dependable pumps that attain excessive supply heads with nice efficiency.” With its new Alligator chopper pump collection, which may even be available as an explosion-proof model, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our aim was to attain high supply pressures in the medium flow price range,” reviews Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and more vitality saving motor than in other pumps in the identical operating vary was sufficient. To achieve this, HOMA developed a model new cutter system that effectively shreds and removes large quantities of numerous solids such as tear-resistant hygiene wipes, plastic luggage and wooden, which additionally get into the wastewater by way of floor water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the damage plate, which can be outfitted with its personal cutter. This design permits the two central parts to work collectively to catch solids, break them down and ultimately remove them from the suction area by way of built-in grooves in the wear plate.
To enable greater effectivity with out compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a result, within the 50 Hz version, a flow fee of up to 130 m³/h and a delivery head of up to 57 m can be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of eight to 20 kW, a circulate fee of up to 140 m³/h and a supply head of up to 82 m are possible. The suction cover mounted on the pump housing can be used to adjust the slicing gap between the impeller and the damage plate with assistance from six set screws. “The energy of our new Alligator sequence, which is on the market for wet well set up as nicely as dry set up, is its nice effectivity and effective cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to realize not solely the finest possible effectivity values within the working range required for these sorts of wastewater purposes, but also to cut back lifecycle prices general, HOMA attaches nice importance to low-maintenance operation along with efficiency. The impeller and wear plate, which are the elements topic to the most stress, are made of extremely durable chilled chrome cast iron, which withstands even abrasive substances similar to sand in the pumped medium. In addition, the hydraulics had been optimally designed for the operating vary using computational fluid dynamics (CFD) to extend efficiency and to remove any chance of solids build up, which may negatively impression performance and result in pricey 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 upkeep prices because of their excessive effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly suitable for waste water functions that require high supply pressure, but at the similar time have to take care of many different kinds of solids.”
HOMA will be presenting the new Alligator chopper pump sequence for the first time at IFAT 2022 in Munich. This and different innovations, such as the upkeep slide with sliding motor mount, might be defined and demonstrated by the HOMA gross sales group in Hall B1 at Stand 429/528.
