New chopper pump achieves excessive effectivity with out compromising on chopping efficiency

Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wood are being discovered more and more typically in wastewater. Pumping and sewage therapy crops are therefore increasingly reaching their limits; models get clogged up and break down.
In times when low lifecycle costs are taking half in an ever more necessary role, HOMA Pumpenfabrik provides an power environment friendly and dependable answer for areas where a excessive supply head is required, however at the identical time, a various range of solids is predicted: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator series enables effective operation via a robust cutter system. Thanks to using extremely sturdy chilled chrome cast iron, the main elements which are topic to essentially the most stress carry out reliably even with abrasive substances corresponding to sand. HOMA might be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle prices are becoming more and more essential in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for vitality saving and dependable pumps that reach high supply heads with nice effectivity.” With its new Alligator chopper pump sequence, which may also be out there as an explosion-proof version, HOMA has developed a particularly environment friendly response to this demand.
Cutter system shreds all solids with high efficiency
“Our goal was to realize excessive delivery pressures within the medium move rate range,” stories Konstantin Pörsch. Without forfeiting เกจวัดแรงดันต่ำ , the improved efficiency meant that a smaller, cheaper and more energy saving motor than in different pumps in the identical working vary was sufficient. To achieve this, HOMA developed a new cutter system that successfully shreds and removes large portions of numerous solids similar to tear-resistant hygiene wipes, plastic luggage and wooden, which also get into the wastewater through floor water. The specifically designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the wear and tear plate, which can additionally be equipped with its own cutter. This design permits the 2 central elements to work together to catch solids, break them down and in the end take away them from the suction space through built-in grooves within the put on plate.
To enable greater effectivity with out compromising on slicing performance, the blades of the impeller additionally curve strongly backwards. As a outcome, in the 50 Hz version, a move fee of as much as 130 m³/h and a delivery 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 eight to 20 kW, a circulate price of as much as a hundred and forty m³/h and a supply head of up to eighty two m are potential. The suction cover mounted on the pump housing can be used to adjust the slicing hole between the impeller and the wear and tear plate with the help of six set screws. “The power of our new Alligator collection, which is on the market for wet nicely installation as well as dry set up, is its nice effectivity and effective cutter system, coupled with a protracted service life,” provides Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to achieve not only the greatest possible efficiency values within the operating vary required for these kinds of wastewater applications, but additionally to cut back lifecycle costs general, HOMA attaches nice importance to low-maintenance operation in addition to efficiency. The impeller and put on plate, which are the components subject to the most stress, are manufactured from extraordinarily sturdy chilled chrome forged iron, which withstands even abrasive substances corresponding to sand in the pumped medium. In addition, the hydraulics had been optimally designed for the working vary using computational fluid dynamics (CFD) to increase efficiency and to remove any possibility of solids build up, which may negatively impact performance and result in costly pump failures. “With the newly developed cutter system, the Alligator pumps can successfully break down all solids within the waste water and transport them away, saving each vitality and maintenance prices because of their excessive effectivity and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water applications that require excessive supply stress, but at the same time have to cope with 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 different innovations, such as 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.
