Suction strainer is a filtration device installed at the suction side of pumps or hydraulic systems to remove solid particles from the fluid before it enters the pump.

Its main function is to prevent contaminants such as rust, debris, sand, or metal particles from damaging pumps, valves, and other critical equipment.


Suction strainers are typically installed:

inside storage tanks

at the inlet of hydraulic pumps

in pipeline suction lines


These strainers act as the first line of protection in fluid systems, helping extend the service life of pumps and maintain stable system operation.

Structure of a Suction Strainer

Filter Mesh: The wire mesh captures solid contaminants from the fluid.

Perforated Support Tube: Provides structural support for the mesh filter and maintains flow strength.

End Caps or Fittings: Male or female threaded connections allow easy installation in pipelines or tanks.

Reinforcement Frame: Improves mechanical strength and prevents deformation during operation.


Applications of Suction Strainers

Hydraulic Systems: Hydraulic pumps require clean fluid to operate efficiently. Suction strainers remove particles before fluid enters the pump.

Oil and Lubrication Systems: Suction strainers protect lubrication pumps from contaminants that may cause wear or damage.

Chemical Processing: Chemical production systems use suction strainers to prevent solid particles from entering pumps and reactors.

Water Treatment Systems: Suction strainers filter sand and debris from raw water before it reaches pumps or filtration units.

Paint and Coating Equipment: Small suction strainers are commonly installed in spray pumps and coating equipment to prevent nozzle clogging.
