5 Materials Overview of available materials Component Material Volute casing Bronze Shaft Stainless steel 1.3 Impeller Plastic (PSU - 3 % glass fibre) Bearings Carbon, resin-impregnated Product benefits Maximum savings of operating costs by high-efficiency motor combined with speed control "All-in" concept saves costs Design principle ensures long service life and high level of comfort Universal use reduces storage costs Certifications Overview Label Effective in: Comment Germany All sizes Selection information Minimum pressure The minimum pressure p min at the pump suction nozzle serves to avoid cavitation noises at an ambient temperature of + C and the indicated fluid temperature T max. The indicated values are applicable up to 3 m above sea level. For installation at altitudes > 3 m, an allowance of.1 bar / 1 m must be added. Minimum pressure p min [bar] specified for the fluid temperature [ C] Size Fluid temperature Minimum pressure [ C] [bar] 3-1, 3-1, -1, Up to 8,5-1, to 95 1, Up to 8,8 81 to 95 1,5 Rio-Eco Therm N 5
