Y-type Filter Selection Principles

Y-type filter selection principles

1. Inlet and outlet diameters:
In principle, the inlet and outlet diameters of the filter should not be less than the inlet diameter of the matching pump, and are generally consistent with the inlet pipe diameter.

2. Nominal pressure:
Determine the pressure level of the filter according to the maximum pressure that may occur in the filter pipeline.

3. Selection of the number of holes:
Mainly consider the particle size of impurities to be intercepted, which is determined according to the process requirements of the medium flow. The particle size that can be intercepted by various specifications of wire mesh can be found in the table "Filter Specifications" below.

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

5. Calculation of filter resistance loss
For water filters, the pressure loss is 0.52~1.2kpa at the generally calculated rated flow rate.
