HEVVY PUMPS, the evolution of TOYO PUMPS, now brings you the next generation of agitator with far superior agitation, mixing and suspension abilities. We introduced the world to its very first Agitator over 40 years ago and now we’re very proud to introduce the patented Suspendore™.

The best just got better:

  • Optimized Thrust: Like the wings of a fighter jet, Suspendore’s™ blades have been engineered to provide the perfect combination of downward and outward thrust without sacrificing efficiency or degrading the suction performance of the pump.
  • Sump vacuuming ability: Compound layers of blades are positioned to optimize the Suspendore’s ability to lift resting solids into suspension so that they can be pumped rather than settle and collect. The Suspendore™ helps our pumps act like a sump vacuum cleaner.
  • Better wear characteristics: The Suspendore™ is engineered to maintain its agitation capability for the longest period possible as it wears. We do this through the very intentional placement of our agitation blades and encapsulating shroud.
  • More modular design: With our new design, it’s the application that drives the Suspendore’s™ size not the pump alone. If your application requires more agitation we can now fit your pump with a bigger sized Suspendore™ to ensure the most optimized mixing result. (some exceptions apply).


  • Maximum Flexibility 
    If your pump performance requirements change, simply change the pumping end to ensure you are always achieving maximum productivity and efficiency.
  • Cost Savings
    No need to buy a brand new piece of equipment when system requirements change. Just change the pump end. If you can standardize on the same pumping ends throughout your plant then you can greatly reduce the need for excessive spare parts inventory.
  • Increased Productivity
    Production is profit. When systems change the lead times of some custom drive units can not only be long but also expensive. If you can recycle your drive unit and simply change your pumping end you can get back into production quicker, cheaper, with less downtime required.
