Walf pump: By guaranteeing high flow rates and heads, these pumps are ideal for use in the industrial and service sectors.
They are used to feed hydrocyclones in the aggregate treatment and washing industry, as well as in all those areas where abrasive and/or acid fluids need to be transferred.
Bodies and impellers can be cast with super alloys of high mechanical abrasion resistance (with a hardness of about 800 HB), or coated with special anti-abrasive rubber compounds.
