Filter press close device is an important part of filter press. According to the close types, filter presses can be divided into manual filter press, mechanical filter press and hydraulic filter press.

 

What is manual filter press? The manual filter press closed is depend on manpower without electricity consumption. It’s suitable for small size filter press machine. The manual filter press include manual jack filter press, manual screw filter press, manual hydraulic filter press etc... 

 

What is mechanical filter press? This filter press type is closed by the screw, which driven by motor and reducer via gears. They have higher close pressure than manual filter press, so that better sealing performance. 

 

What is hydraulic filter press? Their pressing device is hydraulic system, and they adopt electrical connecting pressure gauge to realize pressure keeping. This advantage is labor saving, stable performance and has the best close pressure, so that can ensure high feeding pressure to realize best filtering performance.
