Extend the Useful Life of Process Pumps

Upgrade obsolete Bearing Assemblies to ISO 13709/API 610, 12th (latest) edition and simultaneously lower the Total Cost of Ownership in the process.

Bring any outdated OH2 pump (regardless of the OEM) up to full compliance. This standard upgrade reduces on-site inventory costs, features a quick assembly, and significantly reduces lead time versus new equipment.

Available in 10 API Seal Chamber Sizes (#1-10) and all materials classes (S-4, S-5, S-6, S-8, C-6, A-7, A-8, D-1, D-2).
Cooling
  • Fan cooling with low noise technology
  • Water cooling with finned tubed coolers
  • Finned deflectors improve internal cooling and heat dissipation
Lubrication
  • Ring Oil
  • Pure Oil Mist
  • Purge Oil Mist
Cover and Seal Chamber
  • Designed to the 12th Edition API / ISO 13709
  • API 610 seal chamber sizes: #1/2/3/4/5/6/7/8/9/10
  • Ready to retrofit using any cartridge seal under API 682/ISO 21049
  • API 610 Heating and Cooling Options
  • Includes Cover Wear Ring: Inner diameter of the cover wear ring is machined to mate with the existing impeller hub WR. Engineered to provide the proper clearance and allows cost saving by reusing your impeller hub WR (if possible).
  • Throttle Bushing: Tighter clearances are available for seal chamber pressure control
Shaft
  • Reliability Realized with optimal L/D ratio that your envelope allows
  • Engineered for maximum shaft diameter
  • 6 bearing frames provide maximum space in the seal chamber. More space allows for the largest shaft diameter possible.
  • Low L/D ratio for reduced shaft deflection and extended seal life
  • Shaft end is machined and keyed to match your existing coupling. In most cases, reuse your existing coupling assembly.
Bearing Housing and Bearings
  • Heavy duty bearing housings designed for high suction pressure applications
  • Full compliance with API 610 bearing life requirements
  • Engineered bearing available
  • Finned bearing housing to provide maximum heat dissipation
  • Machined Insulation Slot reduces heat transfer from the stuffing box to the bearing housing
  • Oil Ports for oil mist applications
  • Extended bearing life with better sized bearing options
  • 6 bearing frames provide the best reliability – multiple sizes available to meet your “tailored” load requirements
  • Bearing Seal Options: INPRO™ bearing isolators / Labryrinth Oil Seal / Magnetic Isolators
Drop-In Replacement:
Sundyne Engineers will measure the existing OH2 pump on site using advanced laser scanning technology. Sundyne will provide a new “drop-in” pump that is dimensionally interchangeable with the existing pump. No shutdown needed for engineering of the “drop in” replacement.

Delivery Options:

  • Kit Only: Complete a brief inspection sheet; Sundyne will send the kit machined to size for quick re-assembly. Let Sundyne
  • Do the Work: Send your OH2 to any Sundyne Factory or Authorized Service Center. Sundyne will send you the upgraded pump ready for install.
