      P series canned motor pump is composed of a centrifugal pump and a three-phase AC motor, and its rotor part consists of the overflow part and the shaft of driving motor.

1. Overview
Shield pump is composed of a centrifugal pump and a three-phase AC motor, and its rotor part consists of the overflow part and the shaft of driving motor. The shield is embedded at the inner side of the stator to separate rotator chamber from stator chamber to achieve no leakage. The shield pump is in line with the standards of DIN24256/ISO2858 and API610. According to the use condition, the pump can be divided into standard pump (PCN), liquid gas pump (PNQ), high-temperature pump (PKG), common standard pump (PDC). The shield motor is three phase squirrel cage induction motor with explosion prevention performance conforming to the provisions of GB3836.1, GB3836.2 and GB3836.3 and the explosion prevention mark of Exde2 CT4 (T3). There are two methods to cool the shielding motor: 1. By the transmitted mediums; 2.Through exterior recycling cooler.

2. Structure Features
1)The world advanced hydraulic model is introduced in and improved to reduce electricity consumption.
2)The axial thrust is automatically balanced by use of hydraulics principles.
3)The structure is simple and compact and convenient for maintenance; all wearing parts can be repaired and replaced on the spot; and the volume is small, the noise little and vibration prevented.
3. Application Scope
It is suitable for transmitting corrosive, toxic, flammable, explosive, expensive and volatile mediums and widely used in the fields of chemical industry, petrochemical industry, water supply and drainage, medicine, textile, nuclear electricity and so on.
