Console oil pumps such as NK and NKV

Console oil pumps such as NK and NKV

Purpose: pumps such as NK and NKV and pumping units based on the type of anch and ankV are designed for pumping petroleum products with a temperature of up to 360 ° C in technological processes of oil refineries and petrochemical industries. They can also be used to pump water in explosive zones.

Design: Pumps of oil console NKs and NKV - centrifugal, horizontal, console with an axial entrance, with a radial connector of the case, single -flow, one- or two -stage. The unloading of the axial force is hydraulic. The supporting bracket is unified, equipped with SKF bearings with crankcase and forced cooling. Shaft seals-mechanical with oilcopic stuffing of various types, interchangeable with mechanical end seals of various performance according to plan 52 or plan 53 API 682. A feature of the design of the NK and NKV of the new generation is a durable and rigid welded housing and the presence of a spatular withdrawal from the output from work wheel. Such a technical solution excludes the effect of radial force in the entire work range in filing.

Materials:

  • hulls and lids - forks made of heat -resistant carbon dinked steel with corrosion -resistant surfaces on sealing surfaces;
  • details of the prototype part - casting and forging from chromium steels 20x13l and 30x13;
  • Details of slotting seals - unprotected corrosion -resistant alloys;
  • shaft - varietal rental made of structural alloy steel 40x.

Complete:

  • A collected pump with auxiliary pipelines within the pump;
  • Representative flanges on the pipes;
  • Explosion -proceeding drive electric motor;
  • Connective coupling like a municipal unitary enterprise with a fence;
  • General foundation frame;
  • System for ensuring the work of end seals;
  • Parts of fastening the pump, engine and fence of the coupling;
  • SIP set.
