Centrifugal pumps for slurries and fluids with suspended solids. Constructed with casings and impellers made of cast iron, high-chrome alloy, or stainless steel. Shaft sealing is achieved through a mechanical seal with backup packing. The open impeller design allows for the passage of solids up to 7 mm. Suitable for operation with electric, hydraulic, or internal combustion engines (diesel, gasoline, or gas). Designed with flanges compatible with conventional installations, allowing for equipment replacement without modifying the surrounding setup.
