Strainer baskets

Custom strainer baskets with perforated, woven-mesh-lined or wedge-wire walls. Match the seating rim, basket body, closed bottom and removal handle to the housing; select the filtering surface and support for the process fluid and flow direction.

Construction

How the screen, support and basket fit work together

  • Mesh-lined basketFine mesh does the separation while a perforated body carries load. Keep the liner supported at the base and around the inlet.
  • Perforated basketA perforated wall suits coarse straining when the hole size meets the separation need. A liner adds finer retention and additional pressure loss.
  • Removal clearanceProvide space for the handle, the complete basket body and discharge of retained solids. Define the handle attachment and lifting arrangement together with the maintenance method.
  • Perforated bodyHole size, pitch, plate thickness and pattern set the open area and structural support.
  • Mesh liningThe woven layer defines the finer opening; the backing and rim keep it supported and captured.
  • Wedge-wire surfaceSlot, profile wire, support rods and flow direction define a rigid continuous-slot construction.

Strainer baskets

Start with the basket seat, then define the filtering wall

The rim locates the basket in its housing and establishes the seating boundary. Define its outside diameter, thickness and any step or flange together with the mating seat. Measure basket depth from that datum. This separates the length available for collecting solids from the overall length needed for fitting the handle and closing the housing.

A perforated body provides a rigid wall and a drainage path. In a mesh-lined construction, the woven liner supplies the finer opening while the perforated wall supports it. Identify the liner side, seam, bottom closure and retaining ring on the assembly drawing. For wedge wire, identify the working face and slot direction with the supporting rods; the slots and supports form one screening structure.

Plan how the basket is emptied and returned to service

The handle needs a clear extraction path above the open housing. Include the full body, the handle in its removal position and space to discharge retained material. A hinged or folding handle changes the transport envelope; its attachment and load path belong on the drawing alongside the rim and bottom.

Cleaning access follows the liner construction. A captured liner, a removable liner and an unlined perforated wall expose different seams and recesses during cleaning. Specify the surfaces to inspect after washing, the way the bottom is reached and the positions where the liner is secured. Replacement orders then reproduce both the seating geometry and the complete filtering boundary.

Strainer baskets

Applications

The basket form and screen construction change with debris loading, cleaning access and the equipment that needs protection.

Cooling and process water

Intercept debris before pumps, valves or heat exchangers.

Batch processing

Removable baskets allow periodic inspection and washdown.

Replacement elements

Retain the existing housing and inlet interface while replacing the worn basket.

Pump suction and machinery protection

A supported coarse screen catches debris before rotating equipment. Confirm allowable suction-side pressure loss, basket area and the dirty-basket condition.

Basket fit and load-path checks

Captured solids add weight as well as flow resistance.

Quality control for filtration components
Strainer baskets: Inlet seat
Inlet seat

Inlet seat

Check flange contact, positioning and bypass paths.

Liner attachment

Inspect seams, unsupported gaps and the base transition.

Handling

Check handle joints and whether loaded lifting is part of the design.

Check the seated assembly

Check rim fit, basket depth and handle clearance against the housing. Inspect the liner seam and the wall-to-bottom junction around the full circumference.

Questions before ordering

Why does a basket distort after service?

High differential pressure, blocked area, inadequate supports or heavy collected solids may overload the wall or base. More sheet thickness alone may not solve a poorly distributed load.

Can a finer liner be added?

Often, but it reduces open area and can increase pressure loss. Check attachment, clearance, backing and cleaning frequency.

How much clearance is needed to remove a basket?

Allow at least the basket withdrawal length plus handle and cover clearance in the installed housing. Confirm this against the actual vessel drawing before finalizing depth.

Which dimensions define a replacement basket?

Record the housing seat, rim diameter and thickness, basket outside diameter, depth from the seating face, bottom shape and handle position. Include the filtering wall and any liner-retention details so that the replacement reproduces the complete assembly.

How is a removable liner specified?

Show the mesh construction, liner side, top retaining ring, longitudinal joint and bottom attachment. Define the removal sequence and the surfaces that remain accessible for washing and inspection.

Technical enquiry

Define the dimensions, media, joints and inspection records before confirming the order.
