CDL,CDLF is a kind of vertical non-self priming multistage centrifugal pump, which is driven by a standard electric motor. The motor output shaft directly conects with the pump shaft through a coupling. The pressure resistant cylinder and flow passage components are fixed between pump head and inlet & outlet section with tie-bar bolts. The inlet and outlet are located at the pump bottom at the same plane. This kind of pump can be equipped with an intelligent protector to effectively prevent if from dry-running,out-of-phase and overload. The Motor: Full-enclosed air-blast two-pole standard motor Protection class: IP55 Insulation class: F Standard voltage: 50HZ 1×220-230/240V 3×200-220/346-380V 3×220-240/380-415V 3×380-415V Standard voltage: 60HZ 3×200-230/346-400V 3×200-255/380-440V 3×200-277/380-480V Application: Water supply Industrial boosting Industrial liquid conveying Water treatment Irrigation
