Sewage End Suction Centrifugal Pump                           The Depon® ZX/ZW self-priming pump is an energy saving pump designed with ISO international standard and developed through absorbing and improving the related technical data both and abroad and belongs to self-priming centrifugal pump and uses the mechanical seal of a ceramic ring so as to resist any sandy liquid to go into the sealing face,preventing it from getting scratched. This pump holds the advantages of a compact structure, easy operation, stable movement, easy maintenance, high efficiency, long duration and strong self-suction capacity and, as no foot valve is needed to be mounted on the pipeline and only a certain amount of leading liquid is required to be filled into the pump before work, improves the work condition while simplifying the pipeline system.   ZX/ZW Type Model Notation                       Self-priming Water Pump, Direct driven, CRz driven!
