Filter housings

Filter housings and strainer baskets

The vessel matters as much as the element: housing material, flange standard and basket mesh decide whether a filter can be cleaned, re-basketed and kept in service. Housings and the elements inside them come from the same workshop.

Home/Products/Filter housings & strainers

Filter range

Eight filter types on the line

From a single basket on a transfer line to a multi-cartridge security housing ahead of a membrane skid — specified by medium, rating, pressure and the way the unit is cleaned.

Request a specification
Multi-cartridge security housing
01

Security filter housing

Multi-cartridge precision housing that sits at the end of a treatment train and protects membranes, resin beds and instruments.

  • Single or multi-cartridge, stainless steel body
  • Any element material and rating fitted to the duty
  • Liquid enters at the inlet, passes the element outside-in, exits clean

Basket strainer with quick-opening cover
02

Basket strainer

Small in-line unit that takes coarse solids out before they reach pumps, valves and instruments.

  • Body built from tee, basket, flanges, cover and fasteners
  • Basket and frame fully stainless steel
  • Flange to GB25092-2009 PN1.0; GB, SH, JB, ANSI, DIN and JIS on request

Housing detail →

Return-line filter housings
03

Return-line filter

Mounted on the return line at 1.6 MPa or below, catching wear debris before it reaches the reservoir.

  • Differential pressure switch signals at 0.35 MPa
  • Element cleaned or replaced on the signal
  • Protects the tank charge and the next start-up

Housing detail →

Suction filter housings
04

Suction filter

Coarse protection at the pump inlet, protecting the pump from start-up debris.

  • 25 to 1300 L/min
  • 80 to 180 µm
  • Bore 15 to 90 mm, threaded or flanged

Housing detail →

In-line and single-cartridge housings
05

In-line pressure filter

Pressure-side filtration for hydraulic and transmission lines.

  • 1 to 100 µm, 21 to 210 bar
  • Media BN glass fibre, W stainless mesh, P wood pulp, V sintered mesh
  • Seals in FKM or NBR

Housing detail →

Duplex changeover filter
06

Duplex filter

Two housings on one valve block, changed over without stopping the line.

  • Model family SRLF-330*30P
  • 1 to 30 µm, 60 to 1300 L/min
  • 1.6 MPa, bore 25 to 100 mm

Housing detail →

Three- and five-cartridge housings
07

Coalescing separator filter

Three-stage liquid-liquid separation inside one vessel.

  • Stage 1 coalescer: solids held, droplets grow and settle to the sump
  • Stage 2 separator: oleophilic and hydrophobic, passes oil and blocks free water
  • Water drained at the sump valve, oil leaves dry

Housing detail →

Back-flushing housing with valve train
08

Automatic back-flushing and gas separation

Self-cleaning units for high solids duty, and three-stage separation for fuel gas.

  • Back-flush without dismantling the element stack
  • Gas unit: centrifugal separation, mist capture, then coalescing
  • Efficiency held at high dust load, less manual cleaning

Housing detail →

Basket strainer

The basket is the wear part

Liquid enters the tee, solids are held inside the basket and clean fluid leaves through the outlet. Cleaning means draining the body, lifting the cover flange and either washing the basket or dropping a new one in — so the basket, not the housing, is what you re-order.

Send the bore and mesh
Housing material
Carbon steel Q235, 304, 304L, 316, 316L, titanium
Connection
Internal thread, external thread, butt weld, socket weld
Flange type
Slip-on, weld neck, threaded, lap joint, socket weld
Flange facing
Flat, raised face, tongue and groove, ring joint
Flange standard
GB25092-2009 PN1.0 as standard; other standards and ratings on request

Cleaning routine

  • Drain the body through the bottom plug
  • Release the cover flange and lift the basket out
  • Wash and refit, or fit a new basket when the mesh is damaged

Mesh count, bore and material are the three numbers needed to match a basket to the line.

Baskets

Strainer baskets and basket elements

Mesh count, bore and material change per line — these are the shapes we hold drawings and photographs for.

Send the bore and mesh

Element media

Four media, four duties

The same housing takes quite different elements. Tell us the medium and the target rating and we fit the right one — glass fibre for efficiency, woven mesh where the element has to be washed and reused, sintered mesh where back-flushing and collapse strength matter.

BN · Glass fibre paper
High efficiency on pressure-side hydraulic duty
W · Stainless steel woven mesh
Washable and reusable, coarse to medium rating
P · Wood pulp paper
Deep bed adsorption for fine particulate
V · Stainless steel sintered mesh
Back-flushable, high collapse strength
Filter elements checked on the inspection bench
