PSB800 PTFE Lined Filter Centrifuge For Pharmaceutical Chemical Industry

Introduction

PSB series closed centrifuge is a kind of centrifugal filter equipment with high performance top discharge intermittent operation. It is suitable for solid-liquid separation of suspensions with a solid-liquid ratio of 5%--60%, solid phase particles > 0.01mm, not easy to compress, needs washing, and small liquid viscosity. Widely used in medicine, chemical industry, mining, light industry, food and other fields. Stainless steel, plastic-lined , PTFE-lined and halar-lined centrifuges can be customized for customers according to their industry needs.

The PSB800 PTFE lined filter centrifuge is a high-performance solid-liquid separation machine specifically engineered for industries requiring strong corrosion resistance, high purity, and safe processing conditions. It is widely used in pharmaceutical, chemical, and food processing industries where conventional stainless steel centrifuges may fail due to aggressive materials.

With advanced PTFE lining technology, this centrifuge ensures maximum durability, minimal contamination, and superior filtration efficiency, making it an ideal choice for handling acids, alkalis, and toxic substances.

What Is a PTFE Lined Filter Centrifuge?

A PTFE (Polytetrafluoroethylene) lined filter centrifuge is a type of vertical centrifuge equipped with a perforated basket and filter medium. The internal surfaces are coated with PTFE to provide exceptional resistance against corrosive chemicals.

Compared to standard centrifuges, PTFE-lined models offer:

• Superior resistance to strong acids and alkalis

• Reduced risk of product contamination

• Extended equipment lifespan

• Stable performance in harsh environments

This makes the PSB800 centrifuge particularly suitable for GMP-compliant pharmaceutical production and high-demand chemical processes.

Technical Parameter

Working Principle

The material is fed into the drum by the feeding pipe on the closed casing. Under the action of the centrifugal force, the liquid phase passes through the filter medium and is discharged out of the machine, and the solid phase is trapped in the drum. After the machine is stopped, the cover is opened to discharge from the top.

1. Feeding Stage
The slurry is fed into the rotating basket through the feed pipe.

2. Separation Stage
Under high-speed rotation:

Liquid passes through the filter cloth and basket holes

Solid particles are retained and form a filter cake

3. Washing Stage (Optional)
Clean liquid is sprayed to remove impurities from the cake.

4. Drying Stage
Continued spinning removes residual moisture.

5. Discharge Stage
The solid cake is discharged manually from the top.

This process ensures efficient solid-liquid separation with high clarity filtrate.
