AMG, NPS
Axially split, multistage, between-bearings process pumps
type ВВ3 (API 610)


DESCRIPTION

AMG and NPS are the new series of horizontally mounted, axially split, multistage, between-bearings pumps designed in full compliance with API 610 standard of the latest edition for various industrial applications. The pumps are produced at manufacturing facilities of the HMS Group affiliate companies:

  • APOLLO Goessnitz, Germany: AMG series pumps
  • Nasosenergomash, Ukraine: NPS series pumps


APPLICATION

  • Onshore / offshore production of oil, gas and condensate
  • Transportation of crude oil and oil products
  • Oil refineries and gas processing plants
  • Petrochemical industry
  • Desalination plants


TECHNICAL DATA

  • Capacity range: 20 - 3800 m³/h
  • Head range: 150 - 2400 m
  • Operation pressure: up to 275 bar
  • Rotation speed: up to 2950 rpm
  • Pumped media temperature: - 80 … + 250 °C
  • Specific gravity: over 0.70


DESIGN FEATURES & ADVANTAGES

  • New high-capacity series of horizontally mounted, axially split, multistage, between bearings pumps with double volute casing
  • Excellent suction capability due to double-suction first stage NPSH impeller
  • Back-to-back impellers providing rotor axial balance and low wear of rotating elements
  • Symmetrical casing parts and centreline-located feet ensure uniform temperature expansion of the casing with high-temperature liquids
  • Specially designed pump stages, wear rings and bushings provide uniform pressure drop per mm throughout the pump width for uniform distribution of normal wear of the elements for increased reliability
  • High-strength compact size casing with single row easy accessible bolting simplifies the pump maintenance operations
  • Extra heavy-duty rigid shaft with minimum deflection in operation to extend lifetime of bearings and mechanical seals


SHAFT SEAL

  • Seal chamber, being complaint with API 610 / ISO 13709 requirements, is designed to fit API 682 / ISO 21049 compliant seals of a cartridge type and provides necessary space for tandem and double mechanical seals installation.
