Pump
It is a kind of vertical non-self priming multistage centrifugal pump,which is driven by a standard electric motor. The motor output shaft directly coonects with the pump shaft through a coupling. The pressure resistant cylinder and flow passage components are fixed betwwen pump head and in-and outlet section with tie-bar bolts. The inlet and outle are located at the pump bottom at the same plance. This kind of pump can be equippped with an intelligent protector to effectively prevent it from dry-running, out-of-phase and overload.
