Problematic solids corresponding to sanitary towels, plastic baggage, textiles and wood are being discovered more and more typically in wastewater. Pumping and sewage therapy vegetation are due to this fact increasingly reaching their limits; units get clogged up and break down.
In instances when low lifecycle prices are enjoying an ever more essential function, HOMA Pumpenfabrik offers an vitality efficient and dependable solution for areas the place a excessive delivery head is required, however on the same time, a various range 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 the usage of highly sturdy chilled chrome forged iron, the main parts that are topic to essentially the most stress perform reliably even with abrasive substances corresponding to sand. HOMA will be presenting the brand new Alligator chopper pumps for the first time at IFAT 2022 in Munich.
“The lowest potential lifecycle prices are becoming more and more necessary in water and wastewater purposes,” explains Konstantin Pörsch, Project Manager in the Design & Development division at HOMA Pumpenfabrik GmbH. “There is a growing demand for power saving and reliable pumps that attain high supply heads with nice efficiency.” With its new Alligator chopper pump collection, which may even be out there as an explosion-proof version, HOMA has developed a very efficient response to this demand.
Cutter system shreds all solids with high effectivity
“Our objective was to attain high supply pressures in the medium circulate fee vary,” stories Konstantin Pörsch. Without forfeiting ที่วัดแรงดัน , the improved efficiency meant that a smaller, cheaper and more power saving motor than in different pumps in the identical operating range was sufficient. To obtain this, HOMA developed a model new cutter system that effectively shreds and removes giant portions of numerous solids such as tear-resistant hygiene wipes, plastic luggage and wooden, which also get into the wastewater via floor water. The specifically designed impeller has built-in cutters and a sharp-edged radius of 10 mm to the wear and tear plate, which can also be geared up with its personal cutter. This design permits the two central parts to work collectively to catch solids, break them down and finally take away them from the suction space by way of integrated grooves within the wear plate.
To enable higher effectivity with out compromising on slicing efficiency, the blades of the impeller also curve strongly backwards. As a end result, in the 50 Hz version, a move price of as a lot as 130 m³/h and a supply head of as much as fifty seven m can be achieved with energy consumption of 5 to 12 kW. In the 60 Hz version, with energy consumption of eight to 20 kW, a flow rate of as much as 140 m³/h and a delivery head of up to 82 m are possible. The suction cover mounted on the pump housing can additionally be used to regulate the cutting gap between the impeller and the wear and tear plate with the assist of six set screws. “The strength of our new Alligator collection, which is on the market for wet properly set up in addition to dry set up, is its great 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 attain not solely the best possible effectivity values in the operating range required for these kinds of wastewater functions, but also to minimize back lifecycle prices total, HOMA attaches great significance to low-maintenance operation in addition to efficiency. The impeller and put on plate, which are the parts topic to the most stress, are made from extraordinarily sturdy chilled chrome cast iron, which withstands even abrasive substances similar to sand within the pumped medium. In addition, the hydraulics had been optimally designed for the operating range using computational fluid dynamics (CFD) to extend effectivity and to eliminate any chance of solids building up, which might negatively influence efficiency 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 both vitality and maintenance prices due to their high effectivity and wear-resistant supplies,” Konstantin Pörsch sums up. “This makes them significantly appropriate for waste water functions that require high delivery stress, but on the similar time have to deal with many different sorts 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 upkeep slide with sliding motor mount, will be explained and demonstrated by the HOMA sales team in Hall B1 at Stand 429/528.
