PD type plate type hanging bag centrifuge is an upper discharge centrifuge designed on the basis of traditional tripod hanging bag centrifuge according to GMP standards and environmental hygiene requirements. It eliminates the traditional suspension leg, adopts flat weight and high viscosity damping vibration isolator to absorb vibration, and has no foundation installation. This centrifuge can be used for the suspension liquid's filtering, or the dewatering of fiber sub-stances, and is especially suitable for the filter-ing of mixture, in which the viscosity is high, the granularity is fine, and it is toxic or inflam-mable.
