GOST R 54804-2011 PDF

Full title and description

GOST R 54804-2011 (ГОСТ Р 54804-2011) — "Centrifugal pumps. Technical specifications. Class III" (Russian: "Насосы центробежные. Технические требования. Класс III"). The standard establishes technical requirements for centrifugal pumps of Class III used for general-purpose applications, covering single-stage and multistage designs, horizontal and vertical arrangements, and various mounting and drive options.

Abstract

This national standard specifies design, construction, materials, testing, marking and documentation requirements, as well as rules for installation, operation and safety for centrifugal pumps of Class III. It adapts and aligns with the relevant international practice (based on ISO guidance) to define minimum technical and acceptance criteria for manufacturers, designers and conformity assessment bodies.

General information

• Status: Active / In force (national standard of the Russian Federation).
• Publication date: Introduced into force 01 July 2012; approved by Rosstandart order 13 December 2011.
• Publisher: Federal Agency on Technical Regulating and Metrology (Rosstandart); published commercially via Стандартинформ / national standards publishers.
• ICS / categories: 23.080 — Pumps (hydraulic and pneumatic systems and components).
• Edition / version: Designation year 2011 (first national adoption as GOST R 54804-2011, implemented 2012).
• Number of pages: 24 pages (standard text length).

Scope

The standard applies to single-stage and multistage centrifugal pumps of Class III for general industrial applications, irrespective of drive type and mounting (horizontal or vertical). It covers technical requirements for pump construction, materials, auxiliary piping, support plates and couplings, inspection and testing, marking and documentation, and provisions related to safe operation and maintenance. The drive (prime mover) is excluded from the scope unless it is an integral part of the pump assembly. Deviations and alternative designs may be accepted when agreed between manufacturer and purchaser.

Key topics and requirements

• Definitions and classification of centrifugal pumps by class (Class III) and mounting/drive type.
• Design and construction requirements (materials, corrosion/erosion resistance, clearances, sealing arrangements).
• Performance characteristics and acceptance criteria (rated capacity, head, efficiency ranges and allowable deviations).
• Testing and inspection procedures (factory tests, hydraulic and mechanical checks, routine and type tests).
• Marking, documentation and information to be supplied (nameplate data, technical documentation, operating instructions).
• Requirements for accessories and assemblies included in the pump supply: baseplates, couplings, auxiliary piping; exclusion of non-integral drives unless specified.
• Safety, maintenance and installation recommendations relevant to reliable operation and conformity assessment.

Typical use and users

Used by pump designers, manufacturers and suppliers to define minimum technical requirements for product development and supply; by purchasers and engineers for procurement specifications; by test laboratories and certification bodies for conformity assessment; and by maintenance and commissioning teams to interpret marking, documentation and testing requirements for Class III centrifugal pumps. The standard supports market surveillance and compliance with machinery safety regulations where applicable.

Related standards

This national standard is aligned with and references international and regional documents. It is based on ISO/IEC practice and is associated with ISO 9908:1993 (the international reference indicated for GOST R 54804-2011). Other related Russian pump standards in the same series include GOST R 54805-2011 (Centrifugal pumps. Technical specifications. Class II) and standards referenced for machinery safety and conformity assessment under regional technical regulations (for example provisions related to TR TS 010/2011 on machine and equipment safety).
