เกจวัดco2 as sanitary towels, plastic baggage, textiles and wood are being found increasingly often in wastewater. Pumping and sewage treatment crops are therefore increasingly reaching their limits; units get clogged up and break down.
In occasions when low lifecycle costs are taking part in an ever extra necessary role, HOMA Pumpenfabrik offers an energy efficient and dependable solution for areas the place a excessive supply head is required, but at the similar time, a diverse vary of solids is expected: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator sequence enables effective operation by way of a robust cutter system. Thanks to using extremely sturdy chilled chrome forged iron, the primary parts which may be subject to essentially the most stress carry out reliably even with abrasive substances such as sand. HOMA shall be presenting the new Alligator chopper pumps for the primary time at IFAT 2022 in Munich.
“The lowest potential lifecycle prices have gotten more and more essential in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager within the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for vitality saving and reliable pumps that attain high supply heads with great efficiency.” With its new Alligator chopper pump sequence, which will also be available as an explosion-proof model, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with high efficiency
“Our goal was to attain high delivery pressures within the medium move fee vary,” reports Konstantin Pörsch. Without forfeiting pump fee, the improved effectivity meant that a smaller, cheaper and extra vitality saving motor than in other pumps in the same working vary was enough. To obtain this, HOMA developed a model new cutter system that successfully shreds and removes large portions of numerous solids such as tear-resistant hygiene wipes, plastic baggage and wooden, which additionally get into the wastewater via floor water. The specially designed impeller has integrated cutters and a sharp-edged radius of 10 mm to the wear plate, which is also outfitted 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 space through built-in grooves in the wear plate.
To allow larger effectivity with out compromising on slicing efficiency, the blades of the impeller also curve strongly backwards. As a result, within the 50 Hz model, a flow price of up to 130 m³/h and a delivery head of as much as 57 m can be achieved with power consumption of 5 to 12 kW. In the 60 Hz version, with power consumption of eight to twenty kW, a flow price of up to a hundred and forty m³/h and a delivery head of as much as 82 m are attainable. The suction cover mounted on the pump housing may additionally be used to regulate the slicing gap between the impeller and the damage plate with assistance from six set screws. “The energy of our new Alligator collection, which is available for wet well installation in addition to dry installation, is its nice effectivity and efficient cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle costs thanks to wear-resistant design
In order to attain not only the best possible effectivity values within the working vary required for these sorts of wastewater functions, but in addition to scale back lifecycle prices overall, HOMA attaches nice significance to low-maintenance operation along with efficiency. The impeller and put on plate, which are the parts topic to the most stress, are manufactured from extraordinarily sturdy chilled chrome forged iron, which withstands even abrasive substances such as sand within the pumped medium. In addition, the hydraulics had been optimally designed for the operating vary using computational fluid dynamics (CFD) to increase efficiency and to eliminate any risk of solids build up, which might negatively impression efficiency and lead to expensive pump failures. “With the newly developed cutter system, the Alligator pumps can successfully break down all solids in the waste water and transport them away, saving each power and maintenance costs due to their high efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water applications that require excessive supply pressure, however at the similar time should cope with many different sorts of solids.”
HOMA might be presenting the brand new Alligator chopper pump series for the primary time at IFAT 2022 in Munich. This and other improvements, similar to the maintenance slide with sliding motor mount, might be defined and demonstrated by the HOMA gross sales team in Hall B1 at Stand 429/528.
