Submersible pump - citerne pump - well pump 230 V/50 Hz with built-in switch control and dry run protection with automatic restart. Type COM with 20 meters cable + Schuko plug (cast on) + mounting kit with nylon cord. For use in water supply, rainwater harvesting, irrigation, pressure boosting. As a depth well pump suitable for well pipes of 4" (DN100 = 102 mm on the inner wall) Automatic well pump, multi-stage submersible pressure pump including flow meter. Protection against dry-running and automatic restart at various intervals. After 30 sec = 3 start attempts. After 1 hour = 3 start attempts. After 5 hour = 3 start attempts. After 24 hours = 3 start attempts - Pressure-dependent shutdown at 2.8 bar shutdown pressure - Flow-dependent shutdown - In case of more than 7 start attempts within 200 seconds, the pump stops (suspected leakage) - High operational safety due to built-in (thermal) circuit breaker and self-cooling independent of immersion depth. - Automatic switch with dry-running protection and automatic restart directly in the pump. - Built-in check valve (cannot be removed) - Automatic venting function - Corrosion-resistant materials - stainless steel pump housing - Excellent hydraulic performance Flow (Q) = 5.1 3.6 1.8 0.9 m³/h Head (H) = 20 30 38 40 m Outlet connection: 1" female threaded Length of the pump about 74 cm CAUTION: only works vertically - not horizontally! Built-in capacitor: 15 µF Media temperature: max. 40°C Net weight: 11 kg casing-cooled motor: P2 = 0.6 kW Nominal voltage: 1 x 230 V - 10% / +6% 50 Hz Nominal current: 4,5 A Protection class: IP68 - insulation class B
