AL-Series – 2 Pole Dewatering pumps Suitable for general dewatering applications on construction sites, mines, quarries and foundries.                            Features                                                        Heavy duty cast iron construction with a high-chrome alloy impeller.                            Can be mounted on a duck foot bend for easy installation and maintenance.                                                        Complete cast iron construction with a High-Chrome Alloy impeller Pumps feature a double; back-to-back mechanical seal (Inner = Carbon vs.                            Ceramic, Outer = Silicone carbide vs. Silicone carbide) The seal is located in the oil housing and runs independently from the pumped product. It is thus not dependent on product for cooling or lubrication                            All HCP pumps are fitted with a motor protector “auto cut” thermal device.                             The auto-cut protector is a mechanical thermal switch that cuts power to the electric motor in the event of a power surge, lock rotor, phase failure and overloading.                            The switch automatically restarts the motor once the temperature inside the motor drops to 60-70°C                            Models : 50AL21,5 kW : 1.5 Voltage : 240/400/550 Discharge (mm) : 2”/50 Best Efficiency Point : 400l/min@12,5m Max (H) m : 20 Max (Q) L/min : 700 Solid size (∅mm) : 20 Weight (kg) 1P/3P : Weight (kg) 1P/3P
