Positioned ahead of the pump, Suction Filters and strainers protect it from contamination, while providing additional flow diffusion to the pump suction line.
They are equipped with a magnetic column for retaining ferrous particles and are normally placed under the fluid head to take advantage of the piezometric thrust of the fluid and to reduce the risk of cavitation.
There are two types of suction filters:
- Suction strainer - a simple lter element screwed onto the suction pipe
- Tank wall-mounted suction filters - which are easier to maintain when the element needs replacing due to anti-drain valve
Key features include:
- Wire mesh from 25 µm to 250 µm
