The New OC Series Chopper Pump: Uncompromising Against Solids

News Press release

Problematic solids such as sanitary towels, plastic bags, textiles and wood are being found more and more often in waste water. Pumping and sewage treatment plants are therefore increasingly reaching their limits; units get clogged up and break down. In times when low lifecycle costs are playing an ever more important role, HOMA Pumpenfabrik offers an energy efficient and reliable solution for areas where a high delivery head is required, but at the same time, a diverse range of solids are expected: the Alligator chopper pump series.

The newly developed OC impeller of the Alligator series enables effective operation through a powerful cutter system. Thanks to the use of highly durable chilled chrome cast iron, the main components that are subject to the most stress perform reliably even with abrasive substances such as sand.

“The lowest possible lifecycle costs are also becoming increasingly important in water and waste water applications,” explains Konstantin Pörsch, Project Manager in the Design & Development department at HOMA Pumpenfabrik GmbH. “There is a growing demand for energy saving and reliable pumps that reach high delivery heads with great efficiency.” With its new Alligator chopper pump series, HOMA has developed a particularly efficient response to this demand, which will also be available as an explosion-proof version.

Low lifecycle costs thanks to wear-resistant design

In order to achieve not only the best possible efficiency values in the operating range required for these kinds of waste water applications, but also to reduce lifecycle costs overall, HOMA places a great deal of emphasis on low-maintenance operation in addition to efficiency. The impeller and wear plate, which are the components subject to the most stress, are made of extremely durable chilled chrome cast iron, which withstands even abrasive substances such as sand in the pumped medium. In addition, the hydraulics were optimally designed for the operating range using computational fluid dynamics (CFD) to increase efficiency and to eliminate any possibility of solids building up, which can negatively impact performance and lead to 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 energy and maintenance costs thanks to their high efficiency and wear-resistant materials,” Konstantin Pörsch sums up. “This makes them particularly suitable for waste water applications that require high delivery pressure, but at the same time have to deal with many different kinds of solids.”
