What Is a Filter Pump?
The filter pump is a device for removing fine and harmful solid particles in the solution in the electroplating plant.
- Inside the plating plant, outside dust or any powder can enter
- Filter pumps are generally divided into vertical and horizontal.
Filter pump pocket filter pump
- (1) Exterior structure
- The compact filter pump is suitable for laboratory and ABS plastic electroless plating. Its shape is shown below:
- Structure of pocket filter pump
- The casing of this pump is mostly composed of epoxy resin, and the simple structure inside is as follows:
- Internal structure of pocket filter pump
- (2) Working principle
- After the motor of the filter pump is turned on, the magnet B is driven to rotate, so the magnet A also rotates as the magnet B. Rotating the magnet A also rotates the blade, so that the blade sucks the unfiltered solution through the filter cloth and centrifuges out in the direction indicated by the arrow. The weight of this pump is between 14 and 34 kg, which is very convenient to use. [1]
Filter pump Filter pump using filter aid
- (1) Exterior structure
- This pump must use an acid-resistant casing and an acid-resistant gasket for an acid copper bath. Its size and shape are shown in the following figure:
- Filter pump using filter aid
- (2) Working principle
- The filtering principle of this pump is to use a special acid-resistant nylon filter cloth, and apply a layer of filter aid with a uniform thickness on the surface of the filter cloth. This filter aid helps to completely remove tiny particles. filter. Generally, in order to increase the filtering effect, the surface area of the filter cloth needs to be enlarged. Therefore, a plastic sheet is used to support the fixed position of the filter cloth.
- The filter aid is usually called Pre-coating, which is a very light and extremely tiny white powder, which will have a good auxiliary effect and effect on the filtering effect. The effect diagram is as follows: [1]
