Cast Steel Filter 3

Principles of type selection:

1. Import and export paths:

In principle, the inlet and outlet diameter of the filter should not be less than the matching pump inlet diameter, generally consistent with the inlet pipe intersection diameter.

2. Nominal pressure:

The pressure level of the filter is determined according to the maximum pressure that may occur in the filter pipeline.

3. Selection of the number of holes:

The particle size of the impurities to be intercepted is mainly considered, depending on the technological requirements of the medium process. Various sizes of wire mesh can be intercepted. Look up the "filter mesh specifications" in the table below.

4. Material of filter:

The material of the filter is generally the same as that of the process pipeline connected. For different service conditions, filters made of cast iron, carbon steel, low alloy steel or stainless steel can be selected.

5. Calculation of resistance loss of filter

The pressure loss of water filter is 0.52-1.2 kPa under the normal rated flow rate.
