Selection priorities
Duty, filtration elements, dimensions, materials, interfaces and service conditions

Working principle

Two filter units are connected by pipework. Series, parallel and changeover arrangements serve different purposes; valves and routing determine operation.

Construction & flow path

Two basket bodies are connected by changeover piping. Valves, isolation and flow routing determine whether one side can run while the other is serviced.

Applications & filtration duty

A direction for reducing cleaning shutdowns in pipeline protection. Continuous-operation capability requires an agreed changeover configuration.

Technical parameters

Use these specifications for selection. Materials, dimensions and operating conditions follow the selected model and agreed specification.

Selection information

  • Fluid & viscosity
  • Operating flow (m³/h)
  • Operating / design pressure (MPa)
  • Operating / design temperature (°C)
  • Connection size & standard (DN / in)
  • Differential pressure & service trigger (MPa)
  • Dimensions & service clearance (mm)

Model and configuration notes

Configuration for your application

Share the fluid, filtration goal, operating conditions and installation requirements. Existing models, nameplates or drawings help us review the configuration.

Information to prepare for an inquiry

Use this family’s selection priorities to share available operating conditions, equipment information or drawings.

  • Provide a flow diagram and state any uninterrupted-changeover requirement.
  • Review one-side capacity, pressure loss and isolation.
  • Define changeover valves, vent/drain arrangements and service space.

Operation & maintenance

Before opening, replacing elements or disassembly, stop and isolate under the equipment procedure, depressurize, drain and confirm zero pressure. Follow the actual valve sequence, confirm the serviced body is depressurized and inspect both baskets and changeover seals.

Common operating inputs
  • Fluid and major composition
  • Target flow and operating pattern
  • Operating temperature and pressure
  • Contaminant form and target rating
  • Material, connection and space constraints
  • Maintenance frequency and existing equipment
