Problematic solids such as sanitary towels, plastic luggage, textiles and wooden are being discovered increasingly often in wastewater. Pumping and sewage treatment vegetation are subsequently increasingly reaching their limits; units get clogged up and break down.
In instances when low lifecycle costs are enjoying an ever more essential function, HOMA Pumpenfabrik provides an vitality efficient and reliable answer for areas the place a high delivery head is required, however on the similar time, a various range of solids is expected: the Alligator chopper pump series. The newly developed OC impeller of the Alligator sequence allows efficient operation through a powerful cutter system. Thanks to the use of extremely sturdy chilled chrome cast iron, the primary elements which might be topic to probably the most stress perform reliably even with abrasive substances similar to sand. HOMA will be presenting the brand new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs have gotten more and more essential in water and wastewater functions,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is ขนาดpressuregauge growing demand for energy saving and reliable pumps that reach excessive supply heads with great effectivity.” With its new Alligator chopper pump sequence, which will also be obtainable as an explosion-proof version, 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 price range,” stories Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and more vitality saving motor than in different pumps in the same working vary was sufficient. To achieve this, HOMA developed a new cutter system that effectively shreds and removes massive quantities of numerous solids similar to tear-resistant hygiene wipes, plastic bags and wood, which additionally get into the wastewater through 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 parts to work together to catch solids, break them down and finally take away them from the suction space by way of integrated grooves in the wear plate.
To enable greater effectivity without compromising on cutting performance, the blades of the impeller also curve strongly backwards. As a result, in the 50 Hz model, a flow rate of up to 130 m³/h and a delivery head of as much as fifty seven m can be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with power consumption of 8 to twenty kW, a flow rate of up to 140 m³/h and a supply head of up to eighty two m are possible. The suction cowl mounted on the pump housing can additionally be used to regulate the slicing hole between the impeller and the put on and tear plate with assistance from six set screws. “The energy of our new Alligator series, which is on the market for wet properly set up in addition to dry set up, is its nice effectivity and efficient cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle prices due to wear-resistant design
In order to achieve not solely the very best effectivity values within the working range required for these kinds of wastewater functions, but additionally to reduce lifecycle prices overall, HOMA attaches great importance to low-maintenance operation along with efficiency. The impeller and put on plate, which are the parts subject to probably the most stress, are manufactured from 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 working vary utilizing computational fluid dynamics (CFD) to increase effectivity and to remove any chance of solids increase, which may negatively influence performance and result in costly pump failures. “With the newly developed cutter system, the Alligator pumps can effectively break down all solids in the waste water and transport them away, saving both energy and maintenance costs because of their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water applications that require excessive supply strain, however on the same time should cope with many various sorts of solids.”
HOMA will be presenting the model new Alligator chopper pump collection for the first time at IFAT 2022 in Munich. This and other improvements, such as the maintenance slide with sliding motor mount, shall be defined and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
