We have a long history of designing groundbreaking agitation technology

Our engineering team is always working to stay ahead of the curve and provide you with the most advanced pumping solutions on the market.

Our pioneering agitator changed the game for slurry pumping, delivering superior performance and efficiency in a wide range of applications. But we didn’t stop there – we continue to push the boundaries of what’s possible with our Suspendore™ which is the latest example of our commitment to innovation and excellence, delivering enhanced performance and efficiency in even the most challenging slurry applications.



We introduced the world to its very first agitator over 40 years. The Toyo agitator eliminates solids accumulating on the sump floor and can significantly reduce maintenance costs.

  • The ultimate agitator design

    Holding International patents, the agitator blades are curved towards the direction of rotation while straightening at an oblique angle to the axis of the rotation along the lower portion.

  • The blade shape

    Similar to an aircraft wing, gives the highest efficiency for material mixing and has proven itself in thousands of installations. For this reason, the agitator has unparalleled fluidization performance in: Ball Mill Sumps, Steel Scale Pits, Tailings Reclamation, and Material Excavation in Dredging.

  • When the agitator revolves

    Settled material is mixed with liquid into a highly concentrated slurry. The low-pressure area in front of the pump’s suction, partially caused by the interaction between the impeller and agitator induces material (slurry) back into the pump’s suction. This ensures the longest material path for fluid/material mixing, thus promoting a uniform-density slurry and the highest concentration feasible.



Hevvy, the evolution of Toyo, now brings you the next generation of agitators with far superior agitation, mixing, and suspension abilities, the patented Suspendore™.

  • 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.

We Use Computational Fluid Dynamics software to refine our current products and design new components

Whether it’s a custom impeller and volute for a specific customer application, a new impeller capable of transporting the heaviest solids in the most efficient manner, putting in time researching how wear might affect existing designs or our team developing a brand new agitator which creates the perfect combination of agitation and mixing, our engineering and development lab is always up for the challenge.

Using CFD also opens up more possibilities as it allows us to really look inside our pumping solutions and see what is going on when they are running.  It has also proven invaluable to investigate our current products to see what is really going on and determine areas for improvement by making modifications or even completely redesigning components.

We use flow simulation software to test out more innovative, groundbreaking, and unconventional designs and mathematical optimization software to find the optimal solution.

Modularity offers maximum flexibility and increased productivity while being cost-effective

Our Modular program gives you the flexibility of coupling the pumping ends with different drive configurations

If your pump performance requirements change, simply change the pumping end to ensure you are always achieving maximum productivity and efficiency. 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. 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.

We use our over 20,000 US gallons test tank to conduct comprehensive assessments of our pumps’ performance

Our custom-designed tank is specifically tailored to test large submersible pumps and a hydraulic lift designed for cantilever pumps, providing an ideal environment to evaluate their performance and durability.

Equipped with advanced features like a torque transistor and a command center that enables operators to control the testing process, including operating the actuating valve for seamless control of water flow, the test tank ensures precise and accurate measurements.

This tank is one of a kind in Canada and is the perfect tool to generate performance and power curves, providing essential data for pump analysis and optimization.

With this advanced testing facility, we ensure that every pump we manufacture undergoes thorough evaluation, guaranteeing reliable and high-performing products that meet your needs.

  • Increased Reliability

    Our positive pressure sealing system delivers a more reliable seal than packing or lip seals in applications with high pressure, high temperature, or abrasive fluids.

  • Reduced Leakage

    Avoids contamination by having the positive pressure behind the seal face assuring that a clean film of oil is maintained on the seal face instead of the abrasive slurry.

  • Extended Service Life

    Reduces wear and tear on the shaft and bearings resulting in lower maintenance costs and longer intervals between repairs or replacements.

  • Like an API Plan 54 for Submersible Pumps
