Pumps

About the Pumping Equipment in the Catalogue

This section includes centrifugal pumps of various types: TsNS multistage sectional pumps, type D double-suction pumps, NKV and NK cantilever oil pumps, as well as pumps whose type is still being clarified. Some items are supplied with an electric motor and some without; this is indicated in the card according to inventory records.

For many domestic pumps, the designation contains the main parameters. Thus, per GOST 10407-88, the designation of a TsNS pump consists of the type, the flow rate in m³/h and the head in metres: TsNS 180-1050 means 180 m³/h and 1050 m. Per GOST 10272-87, the same scheme applies to type D pumps: 1D200-90 means 200 m³/h and 90 m. However, the rule does not apply to all designations, so in the cards the series parameters are shown in a separate block with a reference to the source.

Series parameters describe the standard size, not a specific unit in stock. A pump of one standard size is produced in different versions: with impeller trimming options, from different materials, for different media and temperatures. For example, GOST 10407-88 provides for a TsNS version for water and a TsNSs version for aggressive oilfield waters. The specific version is to be confirmed from the nameplate and data sheet.

The “Flow rate from” and “Head from” filters use series reference data. Items for which these data have not been established are hidden when the filter is enabled — they are worth viewing separately.

For selection, state in your request the pumped medium and its temperature, the required flow rate and head, the power supply parameters and the place of delivery. If you are looking for a replacement for an existing unit, attach a photograph of its nameplate — this is the quickest way to compare parameters.
