EnviroPump and Seal VIT Series Power Frame Upgrades

Why Upgrade your Pump?

Improve pump performance, cut downtime, and reduce maintenance cost without
replacing the entire pump. Upgrade only the critical components

If you agree with any of the following statements concerning your existing  centrifugal pumps, then the VIT Upgrade Program can benefit your company:

  • We have more frequent failures of bearing or mechanical seals than we like
  • We need to reduce downtime on our pumps
  • We need to increase interchangeability
  • We need to reduce spare parts inventory
  • We have tried everything we know to increase MTBF, but we want more

The VIT Modular Power Frame Assembly is designed to adapt to virtually any existing pump liquid end that has a back pullout design. The patented system allows one frame, one shaft, one set of bearings, one seal size to fit nearly any ANSI, API, ISO, DIN, JIS, and other types of centrifugal pumps (such as slurry pumps, recessed impeller pumps, self-priming pumps, etc.)

Size VIT-500 is suitable for most pump sizes up to 4x6x10 and up to 75 HP (55 kW)
