PK Pumps with peripheral impeller PERFORMANCE RANGE APPLICATION LIMITS Suitable for use with clean water that does not contain abrasive particles and liquids that are not chemically aggressive towards the materials from which the pump is made. Thanks to their reliability, the fact that they are easy to use and are economical, they are ideal for domestic use and in particular for distributing water in combination with small pressure sets and for the irrigation of gardens and allotments. The pump should be installed in an enclosed environment, or at least sheltered from inclement weather. •• Flow rate up to 90 l/min (5.4 m³/h) •• Head up to 100 m •• Manometric suction lift up to 8 m •• Liquid temperature between -10 °C and +60 °C •• Ambient temperature up to +40 °C (+45 °C for PK 60) •• Max. working pressure: •• CONSTRUCTION AND SAFETY STANDARDS EN 60335-1 IEC 60335-1 CEI 61-150 PATENTS - TRADE MARKS - MODELS •• Registered model PKm60 n° 009875394 •• Motor bracket: patent n° IT1243605 •• (reduces the risk of the impeller locking after long periods of inactivity) Registered Community Design n° 001894478 OPTIONALS AVAILABLE ON REQUEST •• Pump body with NPT ANSI B 1.20.1 threaded ports •• Special mechanical seal •• Other voltages •• IP X5 class protection for PK 70-80-90-100-200-300 GUARANTEE 2 years subject to terms and conditions
