GOST 27854-88 PDF

Full title and description

GOST 27854-88 — "Насосы динамические. Ряды основных параметров" (English: "Rotodynamic pumps. Main parameters series"). This national standard defines preferred (series) values for the main nominal parameters of rotodynamic (centrifugal and similar) pumps used for general-purpose liquid pumping.

Abstract

GOST 27854-88 establishes standard series of nominal pump parameters (nominal head/energy per stage, nominal flow rates, nominal rotational speeds, recommended impeller diameters and conditional passages) to be used when designing and specifying newly developed general-purpose rotodynamic pumps. It gives tables and recommended series for selection of nominal values and includes informative appendices for large flows and recommended impeller diameters.

Scope

The standard applies to newly designed general-purpose rotodynamic pumps for pumping various liquids and specifies the series of main nominal parameters to be used at design and selection stages. It explicitly excludes special-purpose pumps, pumps with parameters set by model testing or custom manufacture, pumps whose main parameters are set by another standard, and pumps operating at nominal speeds different from those assumed in design.

Key topics and requirements

• Defined series (preferred discrete values) for nominal head (nominal specific energy) per stage.
• Defined series of nominal flow rates (Q) for pumps (detailed tabulation and an extension for very large flows).
• Recommended series of nominal rotational speeds (synchronous and asynchronous values) for selection.
• Recommended series of impeller (working wheel) diameters and conditional passages; notes on preferred and non-preferred values.
• Application notes: parameter values are given for water at 20 °C at the nominal rotational frequency; values in brackets are marked as less preferred.

Typical use and users

Engineers and designers of pump equipment, pump manufacturers, specification writers, procurement and standards departments, and technical libraries use this standard to harmonize nominal parameter choices, simplify interchangeability and inventorying, and reduce the variety of pump sizes produced for general industrial, water-supply and process applications.

Related standards

This GOST implements/adopts the CMEA/CIS counterpart ST СЭВ 6049-87 ("Rotodynamic pumps. Main parameters series") as a basis and references other national standards for pumps and hydraulic equipment where appropriate. When selecting pumps the document is typically used alongside product-specific GOSTs and industry normative documents for pump testing, materials and installation.

FAQ

Q: What is this standard?

A: GOST 27854-88 is the USSR/Russian national standard that sets the series of main nominal parameters for rotodynamic (centrifugal-type) pumps used for general-purpose liquid handling.

Q: What does it cover?

A: It covers preferred discrete (series) values for nominal pump head (energy per stage), nominal discharge (flow), nominal rotational speeds, recommended impeller diameters and related selection guidance; it also includes informative appendices for very large flows and recommended wheel diameters.

Q: Who typically uses it?

A: Pump designers and manufacturers, technical specification authors, procurement specialists, and standards/engineering departments concerned with standardizing pump sizes and simplifying design and spare-parts logistics.

Q: Is it current or superseded?

A: The document is shown in multiple standards databases as "in force" (действует) and was introduced on 01 January 1989; users should verify whether a more recent national or international replacement applies to a particular project or jurisdiction before final specification.

Q: Is it part of a series?

A: It forms part of the family of pump-related standards (GOSTs) and implements the CMEA/CIS technical recommendation ST СЭВ 6049-87; complementary GOSTs address testing, materials, dimensional series and specific pump categories.

Q: What are the key keywords?

A: Rotodynamic pumps, nominal parameters, series of values, flow (Q), head (H), rotational speed (n), impeller diameter, pump selection, GOST.
