New chopper pump achieves high efficiency with out compromising on chopping performance

Problematic solids similar to sanitary towels, plastic baggage, textiles and wooden are being discovered increasingly more usually in wastewater. Pumping and sewage remedy plants are therefore increasingly reaching their limits; items get clogged up and break down.
In instances when low lifecycle prices are enjoying an ever more essential position, HOMA Pumpenfabrik provides an energy efficient and dependable resolution for areas the place a high supply head is required, however at the same time, a various vary of solids is predicted: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator sequence permits effective operation via a robust cutter system. Thanks to the use of highly durable chilled chrome cast iron, the principle components that are subject to the most stress perform reliably even with abrasive substances such as sand. HOMA will be presenting the brand new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle costs are becoming increasingly important in water and wastewater functions,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is เกจวัดแรงดันแก๊สlpg growing demand for power saving and reliable pumps that reach excessive supply heads with nice efficiency.” With its new Alligator chopper pump series, which will also be out there as an explosion-proof version, HOMA has developed a very 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 flow price vary,” stories Konstantin Pörsch. Without forfeiting pump fee, the improved efficiency meant that a smaller, cheaper and extra vitality saving motor than in other pumps in the same working vary was adequate. To obtain this, HOMA developed a brand new cutter system that effectively shreds and removes massive portions of diverse solids corresponding to tear-resistant hygiene wipes, plastic bags and wood, which also get into the wastewater via floor water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear plate, which can be geared up with its personal cutter. This design allows the 2 central components to work together to catch solids, break them down and in the end remove them from the suction area through built-in grooves within the wear plate.
To enable higher efficiency without compromising on slicing efficiency, the blades of the impeller also curve strongly backwards. As a result, within the 50 Hz model, a move price of as a lot as one hundred thirty m³/h and a delivery head of as much as fifty seven m can be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of eight to 20 kW, a flow fee of up to a hundred and forty m³/h and a delivery head of up to 82 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 damage plate with the assist of six set screws. “The strength of our new Alligator sequence, which is available for wet nicely set up as well as dry installation, is its great efficiency and effective cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle costs due to wear-resistant design
In order to realize not only the absolute best efficiency values in the operating vary required for these kinds of wastewater applications, but also to scale back lifecycle prices general, HOMA attaches nice significance to low-maintenance operation in addition to effectivity. The impeller and put on plate, that are the elements topic to probably the most stress, are made of extremely sturdy chilled chrome cast iron, which withstands even abrasive substances such as sand within the pumped medium. In addition, the hydraulics had been optimally designed for the working range using computational fluid dynamics (CFD) to extend effectivity and to remove any possibility of solids increase, which might negatively impression performance and result in pricey 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 prices because of their high effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water purposes that require excessive delivery strain, however at the identical time should take care of many various sorts of solids.”
HOMA might be presenting the new Alligator chopper pump series for the primary time at IFAT 2022 in Munich. This and different improvements, corresponding to the maintenance slide with sliding motor mount, shall be defined and demonstrated by the HOMA gross sales group in Hall B1 at Stand 429/528.
