CKR Self-priming liquid ring pumps ➠ with double anti-seize inserts PERFORMANCE RANGE INSTALLATION AND USE • • Suitable for use with clean water or liquids that do not contain abrasive particles and liquids that are not chemically aggressive towards the materials from which the pump is made. As a specific result of the pump’s operating principle they are suitable for use in all situations where a compact self-priming pump is required or where the fluid supply is limited, irregular or contains air. The pump should be installed in an enclosed environment, or at least sheltered from inclement weather. Flow rate up to 50 l/min (3 m³/h) Head up to 51 m APPLICATION LIMITS • • • • • • Manometric suction lift up to 9 m (HS) Liquid temperature between -10 °C and +90 °C Temperature of diesel up to +55°C Ambient temperature up to +40 °C Max. working pressure 6 bar Continuous service S1 PATENTS - TRADE MARKS - MODELS CONSTRUCTION AND SAFETY STANDARDS • • EN 60335-1 IEC 60335-1 CEI 61-150 OPTIONALS AVAILABLE ON REQUEST CERTIFICATIONS EN 60034-1 IEC 60034-1 CEI 2-3 • • • Motor bracket: patent n° IT1243605 Registered Community Design n° 342159-0008 Special mechanical seal Other voltages or 60 Hz frequency IP 55 class protection GUARANTEE 2 years subject to terms and conditions 122
