• Operating head: 11 - 40 m
• Maximum head: 42 m
• Motor shaft output power: 1.15 kW
• Application: Water supply, supply of groundwater to waterworks. Irrigation in horticulture and agriculture. Groundwater lowering. Industrial applications
• Materials: Motor, pump shaft and housing: stainless steel AISI 304
• Impellers and chambers: Polyamide
• Liquid temperature: from 2 °C to 35 °C
• Pump diameter: Ø 74 mm (3 inches)
• Borehole diameter: minimum Ø76 mm
• Installation depth: Maximum 150 m below the static water level. The pump must always be fully submerged during start-up and operation.
• Pump connection size: 1 1/2"
• Pump height: 743 mm
• Minimum distance from the bottom of the borehole: 2 m
• Permissible sand content in the water: 50 g of sand per 1000 l of water
• Protection: Overvoltage, Voltage peaks (up to 6000 V), Overload, Overheating, "Dry" running
• Dry-running protection - Built-in. If the pump has stopped as a result of "dry" running, it will automatically attempt to restart after 5 minutes.
• Protection operation: In the event of overload, the built-in overload protection stops the pump for 5 minutes. After this period the pump attempts to restart. If the pump restarts and the borehole is empty, the pump will stop after 30 seconds.
