KSB-RPH-Process Pumps



rph-heavy-duty-oh2-process-pump-165375_2b.jpg (1000×1413)Design

Ksb-RPH is Horizontal, radially split volute casing pump in back pull-out design to API 610, 11th edition, or ISO 13709 (heavy duty), with radial impeller, single-stage, single-entry, centreline pump feet; with inducer, if required. Design to ATEX.



Refineries, petrochemical and chemical industry, power stations.


Low maintenance costs

  • The selection of a balancing system for the specific duty point markedly reduces axial forces and extends the bearing life.
  • The double volute (DN 80 and above) reduces radial thrust and prevents shaft deflection.
  • This reduces the load on bearings and mechanical seal.
  • Mechanical seals to ISO 24109 / API 682 in cartridge design are easy to install/remove for maintenance.

Low operating costs

  • A choice of more than 70 hydraulic systems enables optimum pump selection to API with higher efficiencies.
