Problematic solids corresponding to sanitary towels, plastic luggage, textiles and wood are being found increasingly typically in wastewater. Pumping and sewage treatment crops are due to this fact increasingly reaching their limits; items get clogged up and break down.
In occasions when low lifecycle costs are enjoying an ever extra important role, HOMA Pumpenfabrik presents an energy efficient and dependable solution for areas the place a excessive supply head is required, however on the identical time, a various vary of solids is predicted: the Alligator chopper pump collection. The newly developed OC impeller of the Alligator series permits effective operation via a strong cutter system. Thanks to using highly durable chilled chrome forged iron, the principle parts which are topic to essentially the most stress carry out reliably even with abrasive substances such as sand. HOMA will be presenting the new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest possible lifecycle costs are becoming increasingly necessary in water and wastewater applications,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a rising demand for energy saving and dependable pumps that reach high supply heads with great efficiency.” With its new Alligator chopper pump collection, which may even be out there as an explosion-proof model, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with excessive efficiency
“Our aim was to achieve high supply pressures within the medium flow price vary,” reports Konstantin Pörsch. Without forfeiting pump price, the improved effectivity meant that a smaller, cheaper and more vitality saving motor than in different pumps in the same operating range was sufficient. To obtain this, HOMA developed a new cutter system that successfully shreds and removes massive portions of various solids corresponding to tear-resistant hygiene wipes, plastic luggage and wood, which also get into the wastewater through floor water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the put on and tear plate, which can be geared up with its personal cutter. This design permits the 2 central elements to work collectively to catch solids, break them down and in the end remove them from the suction area via integrated grooves in the put on plate.
To allow higher efficiency without compromising on chopping efficiency, the blades of the impeller additionally curve strongly backwards. As a end result, in the 50 Hz model, a circulate fee of as a lot as one hundred thirty m³/h and a delivery head of up to 57 m can be achieved with energy consumption of 5 to 12 kW. In the 60 Hz model, with energy consumption of 8 to 20 kW, a flow fee of up to 140 m³/h and a delivery head of up to 82 m are attainable. The suction cover mounted on the pump housing can additionally be used to adjust the slicing gap between the impeller and the damage plate with the help of six set screws. “The energy of our new Alligator collection, which is out there for moist properly set up as well as dry set up, is its nice efficiency and effective cutter system, coupled with a protracted service life,” adds Konstantin Pörsch.
Low lifecycle prices thanks to wear-resistant design
In order to realize not solely the absolute best effectivity values in the working vary required for these sorts of wastewater purposes, but additionally to scale back lifecycle prices overall, HOMA attaches great importance to low-maintenance operation in addition to effectivity. The impeller and wear plate, which are the components subject to the most stress, are made of extremely durable chilled chrome forged iron, which withstands even abrasive substances corresponding to sand within the pumped medium. In เกจวัดแรงดันเครื่องกรองน้ำ , the hydraulics were optimally designed for the working vary using computational fluid dynamics (CFD) to extend effectivity and to get rid of any chance of solids build up, which can negatively impact efficiency and lead to expensive 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 costs due to their high efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them particularly appropriate for waste water applications that require high supply stress, but at the similar time should deal with many various sorts of solids.”
HOMA will be presenting the new Alligator chopper pump sequence for the primary time at IFAT 2022 in Munich. This and other improvements, corresponding to the maintenance slide with sliding motor mount, shall be explained and demonstrated by the HOMA gross sales staff in Hall B1 at Stand 429/528.
