Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wooden are being discovered increasingly often in wastewater. Pumping and sewage remedy crops are therefore increasingly reaching their limits; items get clogged up and break down.
In times when low lifecycle prices are taking half in an ever more important role, HOMA Pumpenfabrik offers an vitality environment friendly and dependable resolution for areas where a high supply head is required, however on the identical time, a various range of solids is expected: the Alligator chopper pump sequence. The newly developed OC impeller of the Alligator sequence allows effective operation by way of a strong cutter system. Thanks to the usage of extremely durable chilled chrome cast iron, the primary components which may be subject to essentially the most stress perform reliably even with abrasive substances such as sand. HOMA will be presenting ขนาดpressuregauge for the primary time at IFAT 2022 in Munich.
“The lowest attainable lifecycle costs are becoming increasingly important in water and wastewater applications,” 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 attain high delivery heads with nice efficiency.” With its new Alligator chopper pump sequence, which will also be out there as an explosion-proof version, HOMA has developed a particularly efficient response to this demand.
Cutter system shreds all solids with high efficiency
“Our goal was to realize excessive supply pressures in the medium circulate rate vary,” reports Konstantin Pörsch. Without forfeiting pump rate, the improved efficiency meant that a smaller, cheaper and extra energy saving motor than in other pumps in the identical operating range was enough. To achieve this, HOMA developed a model new cutter system that successfully shreds and removes massive portions of various solids similar to tear-resistant hygiene wipes, plastic baggage and wooden, which additionally get into the wastewater by way of floor water. The specially designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear plate, which can additionally be equipped with its personal cutter. This design allows the two central parts to work collectively to catch solids, break them down and finally take away them from the suction area via integrated grooves within the wear plate.
To enable greater efficiency without compromising on chopping efficiency, the blades of the impeller additionally curve strongly backwards. As a result, in the 50 Hz model, a flow rate of as a lot as a hundred thirty m³/h and a delivery head of up to fifty seven m may be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of 8 to twenty kW, a circulate price of up to a hundred and forty m³/h and a supply head of up to 82 m are possible. The suction cowl mounted on the pump housing can additionally be used to adjust the cutting hole between the impeller and the put on and tear plate with assistance from six set screws. “The strength of our new Alligator sequence, which is on the market for moist properly set up as nicely as dry installation, is its great effectivity and efficient cutter system, coupled with a long service life,” provides Konstantin Pörsch.
Low lifecycle prices because of wear-resistant design
In order to achieve not only the absolute best effectivity values in the operating range required for these sorts of wastewater functions, but in addition to minimize back lifecycle costs general, HOMA attaches great importance to low-maintenance operation in addition to efficiency. The impeller and wear plate, that are the parts topic to essentially the most stress, are made from extremely sturdy chilled chrome forged iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics had been optimally designed for the working range utilizing computational fluid dynamics (CFD) to extend efficiency and to eliminate any risk 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 effectively break down all solids in the waste water and transport them away, saving both power and maintenance costs due to their excessive efficiency and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water purposes that require high supply pressure, but on the similar time have to deal with many different sorts of solids.”
HOMA shall be presenting the new Alligator chopper pump sequence for the first time at IFAT 2022 in Munich. This and other improvements, corresponding to the maintenance slide with sliding motor mount, might be explained and demonstrated by the HOMA sales staff in Hall B1 at Stand 429/528.
