SMD,SMC is a stainless steel single stage centrifugal pump,which conveys the liquid by rotating the impeller with the centrifugal force. The pump body is mainly composed of shaft, impeller, diffuser, pump casing, and mechanical seal, which are connected with the motor. SMD,SMC series use the stainless steel plate design Back pullout construction makes the assembly and overhaul of the impeller and seal without distorting suction and discharge connections. technology such as stamping,bulging and well. SMD series is a one-piece design with an extended shaft connection for the motor while the SMC series is a rigid connection design for the NanYuan B35 motor.
