Pumps in waste and energy recovery plants are exposed to high loads. Rainwater shafts and leachate often contain coarse solids that can quickly clog conventional pumps. HOMA cutting wheel pumps from the OC Alligator and GRP Barracuda series reliably shred these materials, ensuring trouble-free operation. The heavily contaminated leachate from landfills varies greatly in pH value (3–12) depending on the composition of the waste – corrosion-resistant stainless-steel pumps from the CTP, CH, CV and CMX series are used here. In waste-to-energy plants, HOMA pumps are used in processes similar to those in coal-fired power plants and meet the highest requirements for temperature and media resistance – for maximum operational reliability and energy efficiency.
