Product Description

High Temperature Resistance PP Material Filter Plate for Filter Press Machine
Features Description
High-pressure pressing Can be squeezed twice, the moisture content of filter cake is 10%-30% lower than that of ordinary filter plate.
High-efficiency filtration Shorten the filtration cycle and increase the production capacity.
Flexible diaphragm Strong fatigue resistance, can be repeatedly expanded/contracted for tens of thousands of times.
Corrosion-resistant PP/rubber material adapts to acid and alkali environment.
Washable The filter cloth is removable for easy maintenance.
Structure and working principle of diaphragm filter plate

(1) Basic structure

Diaphragm filter plate is composed of rigid substrate + elastic diaphragm (rubber or polymer material), mainly divided into:

Polypropylene (PP) diaphragm filter plate: acid and alkali resistant, suitable for general industrial filtration.
Rubber diaphragm filter plate (EPDM/NBR): high temperature and oil resistant, suitable for special working conditions (such as oil, food industry).
Composite diaphragm filter plate: combined with metal skeleton to enhance strength, used for high-pressure filtration.

Typical structure:

Feed hole: the channel for the slurry to enter the filtration chamber.
Drainage channel: path for filtrate discharge.
Diaphragm chamber: Expanded after inflation/water filling, squeezing the filter cake.

Frequently Asked Questions (FAQ)
What are the primary benefits of using a high-pressure pressing diaphragm filter plate?
It allows for secondary squeezing, reducing the moisture content of the filter cake by 10% to 30% compared to ordinary filter plates, which shortens the filtration cycle and increases production capacity.
What material options are available for diaphragm filter plates?
The rigid substrate and elastic diaphragm are available in Polypropylene (PP) for acid and alkali resistance, Rubber (EPDM/NBR) for high temperature and oil resistance, or as composite diaphragm filter plates combined with a metal skeleton for high-pressure filtration.
What are the main structural components of a typical diaphragm filter plate?
A typical structure includes a feed hole for slurry entrance, a drainage channel for filtrate discharge, and a diaphragm chamber that expands to squeeze the filter cake.
Are the diaphragms on these filter plates durable?
Yes. The flexible diaphragms have strong fatigue resistance and can be repeatedly expanded and contracted tens of thousands of times.
Is the filter cloth on the PP filter plate replaceable?
Yes, the filter cloth is removable and washable, which allows for easy maintenance and sustained filtration performance.
