Overview - EN ISO 2858:2010 (ISO 2858:1975)
EN ISO 2858:2010 specifies key parameters, designation rules, nominal duty points and principal dimensions for end‑suction centrifugal pumps (rating 16 bar). The standard defines a simple, consistent pump identification system and dimensional data (including side and front views) to promote interchangeability and clear specification between manufacturers, users and testing authorities. Flange branch sizes covered in the published tables range from 50 mm up to and including 200 mm.
Key topics and requirements
- Pump designation: A three‑number code - inlet diameter – outlet diameter – nominal impeller diameter.
- Example: 80‑50‑250 = 80 mm inlet, 50 mm outlet, 250 mm impeller.
- Nominal duty point and dimensions: Standardised nominal duty point definitions and a table of principal dimensions with accompanying side and front views to support engineering drawings and procurement.
- Pressure rating and testing: Pumps are specified for a maximum operating rating of 16 bar. Static test pressure is 1.5 × maximum discharge pressure, but shall not exceed 24 bar; the relation between cold test pressure and hot operating pressure is to be agreed between manufacturer and user.
- Connections and tapping points: All connections follow ISO/R 228 (pipe threads). Typical tapping points include a 3/8 in. connection for cooling/heating supply and stuffing box tappings not to exceed 1/2 in.
- Rotation and construction notes: Rotation is clockwise when viewed from the driven end. Some dimensions/forms are left to manufacturer discretion; branch sizes in brackets may be limited‑time options.
- Scope limits: Applies to end‑suction pumps with PN16 rating and referenced flange dimensions (ISO 2084/ISO 7005).
Applications - who uses EN ISO 2858
- Pump manufacturers and OEMs for consistent product designation and dimensional base lines.
- Piping and mechanical design engineers specifying pump interfaces, suction/discharge flanges, and shaft heights.
- Procurement and asset owners ensuring interchangeability and compatibility across suppliers.
- Test laboratories and commissioning teams applying the specified static test pressures and tapping requirements.
- Maintenance and spare‑parts specialists using standard nominal impeller diameters and flange sizes for replacements.
