Overview

Water and wastewater systems need durable, corrosion-resistant parts that operate continuously for many years. Typical parts include pump casings and impellers, valve bodies and gates, stainless piping and fittings, screens, clarifier components and tanks.

Türkiye has a strong base of pump and valve manufacturers and stainless fabricators serving municipal and industrial water projects at home and abroad.

On Metraxio you describe the part, attach drawings and state material, pressure rating and quantity. The platform structures the requirement and shows which facilities are a technical fit.

Water and wastewater equipment must resist corrosion for decades in wet, often chemically treated environments. Stating the media, stainless grade or coating system and any drinking-water contact requirements helps identify facilities with the right materials and welding experience.

Typical parts & components

  • Pump casings, impellers and shafts
  • Valve bodies, discs and gates
  • Stainless piping spools and fittings
  • Screens, grids and filter parts
  • Clarifier and aeration components
  • Tanks, covers and walkways
  • Flanges and couplings

The processes, materials and requirements below are an editorial reference of what is typical for water & wastewater programs — not a statement about facilities in the Metraxio network.

Common manufacturing processes

Typical materials & grades

Certifications & compliance

What buyers in this industry commonly ask suppliers for. Exact requirements depend on the program, customer and part.

Supplier certifications

  • ISO 9001 Typically required

    Baseline quality system.

  • ISO 14001 Common

    Often requested in public projects.

  • ISO 3834 Sometimes requested

    Welding quality system.

Standards & regulations

  • EN 10204 Type 3.1 Typically required

    Material certificate for metallic raw material.

  • Pressure Equipment Directive (PED) Sometimes requested

    For pressure equipment above the thresholds.

  • CE Marking Common

    CE marking for complete machinery.

Quality & documentation

  • Material certificates to EN 10204 3.1.
  • Pressure testing of valves and pump casings.
  • Drinking-water compliance for materials in contact with potable water.
  • Welding with pickling and passivation for stainless parts.
  • Coating documentation for carbon steel parts.

Typical tolerances & surfaces

  • Pump shafts and bearing seats: typically ±0.01–0.03 mm.
  • Impellers: dimensional and balance tolerances per drawing.
  • Flanges: dimensions per EN 1092-1.
  • Welded spools: tolerances per the piping specification.

Sourcing from Türkiye

Türkiye combines a deep contract-manufacturing base with short routes into Europe. Industrial goods move between Türkiye and the EU under the customs union, so buyers typically avoid EU import duties on qualifying parts.

  • Many European destinations can be reached by road within several days; actual transit depends on origin, destination, customs handling and cargo.
  • Common delivery terms are EXW, FCA and DAP; Metraxio keeps the agreed Incoterm attached to the quotation and order.
  • State whether parts are in contact with drinking water, as this affects the permitted materials and coatings.

How Metraxio qualifies suppliers

Every request is checked against each facility's structured profile before any supplier is invited.

  • Hard criteria: the required process (e.g. casting or welding), the specified material and grade, and required certifications.
  • Missing data is not a rejection. If a facility profile does not yet state something, the result is "Needs More Information" rather than "Not Qualified".
  • No match yet? You can continue with Managed Sourcing and the Metraxio team runs supplier discovery for you.
  • Facility identities stay anonymous during the technical assessment.

Example project

How a typical request moves through Metraxio

80 stainless pump impellers — 316 — balanced — DAP.

  • The buyer uploads drawings for cast and machined impellers.
  • Metraxio structures the requirement: casting, CNC machining, balancing, stainless steel 316 and DAP delivery.
  • The fit assessment shows which facilities are qualified, which need more information and which do not match.
  • The buyer invites qualified facilities to a Supplier RFQ, or hands the job to Managed Sourcing.

Frequently asked questions

Which materials are common?

Stainless steel 304 and 316, ductile and grey cast iron, bronze and plastics such as PE and PVC.

Do parts need drinking-water approval?

Parts in contact with potable water usually require materials and coatings approved for drinking water in the target country.

Can suppliers balance impellers?

Many pump-part suppliers balance impellers in-house; list balancing with your requirement.

Are large fabricated parts possible?

Yes. Stainless fabrication of screens, tanks and walkways is common.

Are supplier names visible during the assessment?

No. Facilities are shown anonymously during the technical assessment. Identities are shared as the engagement progresses.
