    TG03

Multistage, horizontal high-pressure pump in barrel design, as back-to-back version. The process pump is particularly suitable for big volumetric flow rates and has a modular design for the best possible adaptation to customers’ requirements and low operating costs.

Based on the excellent hydraulic characteristics and the high reliability in critical applications, the pumps are suitable for applications such as:

  • applications in the oil and gas industry
  • offshore applications 
  • booster applications in all industrial branches
  • water injection onshore and offshore 
  • boiler feed water applications
  • Q= 1 800 m³/h
  • H= 4 200 m
  • P= 450 bar
  • T= +420 °C
  • the “pull-out” version ensures maximum serviceability. Barrel remains in the piping. The pump as an insert unit can be dismantled and serviced.
  • very short standstill time during maintenance work thanks to cartridge design
  • 1st stage designed as NPSH stage
  • sealing area designed according to API 610 / 682
  • centerline-supported
  • single impeller support depending on design
  • API 610 requires stable rotor dynamics even on double clearance - a „back-to-back“ arrangement with bearing in the middle fulfills this requirement
  • suitable for high number of stages and high speeds even on small viscosity
  • small bearing loads by compensation of axial thrust
  • wear of casing wear rings has just very small influence upon axial thrust
  • pump is especially suitable for critical application cases and high speeds
  • grey cast iron
  • ductile cast iron, ADI materials
  • cast steel
  • 12 % chromium steel
  • austenitic steel
  • special alloys
  • Q= 700 m³/h
  • H= 4200 m
  • P= 450 bar
  • T= +360 °C
     
  • version for speeds up to 6000 r.p.m.
  • as a result of speed increase reduction of number of stages and investment cost
  • special rotor design for high speeds
  • exact analysis of critical speeds ensures stable runability in the whole operating range
  • radial-axial slide bearings with forced oil lubrication
