GOST R 54805-2011 PDF

Full title and description

GOST R 54805-2011 — "Centrifugal pumps. Technical specifications. Class II". National standard of the Russian Federation, a modified adoption of ISO 5199:2002 describing technical requirements for Class II centrifugal pumps (single- and multistage, horizontal or vertical) for general service applications.

Abstract

This standard specifies design, performance, testing and documentation requirements for centrifugal pumps of Class II used in general industrial service. It sets out constructional requirements, materials and tolerances, factory and type testing, marking and accompanying documentation intended to ensure safe, interchangeable and reliable pump operation in a wide range of fluids and duty conditions.

General information

• Status: Active (in force).
• Publication date: Introduced into effect 1 July 2012 (approved by Rosstandart order in December 2011).
• Publisher: National standard of the Russian Federation — Federal Agency on Technical Regulating and Metrology (Rosstandart).
• ICS / categories: Pumps and compressors; ICS code related area 23.080 (hydraulic and pneumatic systems and components).
• Edition / version: GOST R 54805-2011 (adoption/modification of ISO 5199:2002).
• Number of pages: Approximately 53 pages (published PDF editions commonly listed as 53–54 pages).

Scope

The standard applies to single- and multistage centrifugal pumps of Class II, regardless of drive type and mounting arrangement, intended for general industrial service. It covers overall technical requirements for pump construction, materials, allowable tolerances, performance characteristics, shaft sealing and bearing arrangements, factory acceptance tests and documentation. It does not replace industry- or application‑specific rules where those impose additional requirements.

Key topics and requirements

• Definitions and classification of Class II centrifugal pumps (single- and multistage; horizontal/vertical).
• Design and constructional requirements for casings, impellers, shafts and bearing supports.
• Material selection and corrosion/erosion considerations for wetted parts.
• Permissible dimensional tolerances and manufacturing accuracy.
• Shaft sealing arrangements (packing, mechanical seals) and sealing‑fluid/flush considerations.
• Performance parameters (flow, head, efficiency), allowable deviations and test conditions (factory and hydraulic tests).
• Vibration, bearing temperature limits, noise and operating safety requirements.
• Marking, technical documentation, nameplate data and information supplied with the pump.

Typical use and users

Used by pump manufacturers, hydraulic designers, equipment procurement and quality departments, test laboratories, certification bodies and maintenance engineers. Typical application areas include water and utility services, process industries, HVAC, chemical and petrochemical installations where Class II performance and interchangeability are required.

Related standards

Directly based on ISO 5199:2002 (Technical specifications for centrifugal pumps — Class II). Companion national standards for pumps include the Class I counterpart (GOST R 54806-2011) and other GOST/ISO documents covering testing methods, noise and vibration limits, and specific application requirements.
