Problematic solids corresponding to sanitary towels, plastic luggage, textiles and wood are being found increasingly more often in wastewater. Pumping and เกจวัดแรงดันน้ำประปาราคา are therefore more and more reaching their limits; units get clogged up and break down.
In occasions when low lifecycle prices are enjoying an ever more important function, HOMA Pumpenfabrik presents an vitality efficient and dependable resolution for areas the place a excessive supply head is required, but on the identical time, a diverse range of solids is predicted: the Alligator chopper pump series. The newly developed OC impeller of the Alligator series enables efficient operation by way of a powerful cutter system. Thanks to the usage of extremely durable chilled chrome cast iron, the principle components which would possibly be subject to essentially the most stress perform reliably even with abrasive substances such as sand. HOMA shall be presenting the model new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs are becoming more and more necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager within the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a rising demand for energy saving and reliable pumps that attain excessive supply heads with great effectivity.” With its new Alligator chopper pump collection, which may even be available as an explosion-proof model, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with excessive effectivity
“Our objective was to realize excessive supply pressures in the medium circulate rate range,” reports Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and extra vitality saving motor than in other pumps in the same working range was sufficient. To achieve this, HOMA developed a brand new cutter system that successfully shreds and removes massive quantities of diverse solids similar to tear-resistant hygiene wipes, plastic baggage and wood, which also get into the wastewater through floor water. The specially designed impeller has built-in 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 two central parts to work together to catch solids, break them down and in the end remove them from the suction space through built-in grooves within the wear plate.
To enable greater efficiency without compromising on chopping performance, the blades of the impeller also curve strongly backwards. As a outcome, in the 50 Hz model, a circulate rate of as much as one hundred thirty m³/h and a supply head of as much as fifty seven m can be achieved with power consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of 8 to twenty kW, a circulate fee of as a lot as a hundred and forty m³/h and a delivery head of up to 82 m are possible. The suction cover mounted on the pump housing can be used to regulate the chopping hole between the impeller and the wear plate with the help of six set screws. “The strength of our new Alligator series, which is out there for moist properly installation in addition to dry installation, is its nice efficiency and efficient cutter system, coupled with a long service life,” adds Konstantin Pörsch.
Low lifecycle costs because of wear-resistant design
In order to realize not solely the very best efficiency values in the working vary required for these kinds of wastewater functions, but additionally to reduce lifecycle prices general, HOMA attaches nice importance to low-maintenance operation in addition to efficiency. The impeller and put on plate, which are the components topic to probably the most stress, are manufactured from extraordinarily 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 working vary utilizing computational fluid dynamics (CFD) to extend effectivity and to get rid of any chance of solids increase, which might negatively impact performance and lead to pricey 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 energy and upkeep prices because of their high efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them significantly suitable for waste water applications that require high supply stress, however at the similar time should deal with many various sorts of solids.”
HOMA shall be presenting the new Alligator chopper pump sequence for the first time at IFAT 2022 in Munich. This and different innovations, corresponding to the upkeep slide with sliding motor mount, might be explained and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
