Problematic solids such as sanitary towels, plastic bags, textiles and wood are being found increasingly more usually in wastewater. Pumping and sewage treatment vegetation are subsequently increasingly reaching their limits; units get clogged up and break down.
In occasions when low lifecycle prices are playing an ever extra important position, HOMA Pumpenfabrik presents an vitality efficient and reliable solution for areas where a excessive delivery head is required, but at the similar time, a diverse range of solids is anticipated: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator series permits effective operation by way of a robust cutter system. Thanks to using extremely sturdy chilled chrome cast iron, the main elements which would possibly be subject 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 potential lifecycle costs are becoming increasingly essential in water and wastewater applications,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for energy saving and reliable pumps that reach excessive supply heads with nice effectivity.” With its new Alligator chopper pump collection, which will also be available as an explosion-proof version, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with high effectivity
“Our aim was to attain high supply pressures in the medium flow fee vary,” reviews Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and more power saving motor than in different pumps in the same working vary was enough. To achieve this, HOMA developed a new cutter system that effectively shreds and removes large quantities of diverse solids corresponding to tear-resistant hygiene wipes, plastic luggage and wooden, which also get into the wastewater by way of surface water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the put on and tear plate, which is also geared up with its personal cutter. เกจวัดแรงดัน300psi allows the 2 central parts to work collectively 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 efficiency with out compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a end result, within the 50 Hz model, a circulate rate of up to 130 m³/h and a supply head of up to fifty seven 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 move fee of as much as a hundred and forty m³/h and a supply head of up to 82 m are potential. The suction cover mounted on the pump housing may additionally be used to regulate the slicing gap between the impeller and the wear and tear plate with the help of six set screws. “The power of our new Alligator sequence, which is out there for moist nicely installation in addition to dry installation, is its great effectivity and efficient cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to realize not solely the finest possible effectivity values in the operating vary required for these sorts of wastewater purposes, but in addition to scale back lifecycle costs total, HOMA attaches nice significance to low-maintenance operation in addition to efficiency. The impeller and put on plate, that are the elements subject to the most stress, are made from extremely durable chilled chrome forged iron, which withstands even abrasive substances similar to sand in the pumped medium. In addition, the hydraulics were optimally designed for the operating range utilizing computational fluid dynamics (CFD) to extend efficiency and to get rid of any chance of solids increase, which may negatively impact performance and result in pricey 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 vitality and maintenance prices due to their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water functions that require high supply stress, however on the similar time have to deal with many different sorts of solids.”
HOMA shall be presenting the new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and different improvements, similar to the maintenance slide with sliding motor mount, shall be explained and demonstrated by the HOMA sales group in Hall B1 at Stand 429/528.
